YF-Z Series Automatic Corrugated Board Box Gluing and Bundling Machine

The YF-Z Series is an automatic corrugated board box gluing and bundling machine with a fully modular architecture, integrating in-line suction feeding, folding, differential correction, full alignment, output and bundling into stacks. Designed for packaging manufacturers that process large-format boxes with strict folding and gluing accuracy requirements, this automatic corrugated board box gluing and bundling machine reaches 130 m/min with a box front of up to 1000 mm on the 1630Z model — one of the largest processable formats in an automatic folder-gluer available in Romania.

Compared with the HS-A, HS-B and HS-C series, which use variable-frequency alignment systems and navigation buoys, the YF-Z Series introduces two distinct technical systems: differential correction with independent left-right control and full alignment with linear rails and lateral belt — a more robust mechanical architecture for heavy boxes and large formats where conventional alignment systems generate wobble or incomplete folding.

Key advantages of the YF-Z Series automatic corrugated board box gluing and bundling machine

• Differential correction with independent left-right control – the differential correction system allows the speed on each side of the line to be adjusted independently, compensating for variations in board thickness or rigidity and preventing wobble when packing heavy products — a common problem on conventional folder-gluers with large formats and dense materials.

• Full alignment with linear rails and left-right lateral belt – the guide structure with linear rails and a lateral belt on both edges of the box ensures precise alignment along the entire length of the folding line, with an active lateral alignment function that corrects deviations from the center axis in real time.

• Synchronized transverse movement of the left-right arms – the left and right folding arms move synchronously and transversely together with the deflectors and the gluing mechanism, preventing any lateral wobble and ensuring perfectly symmetric folding across the entire box width.

• Multi-channel forming device for the box corner – the multi-channel system ensures correct forming of the 90° angle at the box corner; the additional bidirectional structure prevents the phenomenon of incomplete folding common on thick or rigid board.

• One-key adjustment — length, width and height simultaneously – the automatic corrugated board box gluing and bundling machine performs the complete adjustment function with a single key, with direct entry of the dimensions; no separate adjustments are needed on each station when changing format.

• Box front up to 1000 mm (1630Z model) – the maximum box front format of 1000 mm and back of 1100 mm on the 1630Z model exceeds the capacity of all other folder-gluer series in the UZINEX portfolio, covering large industrial boxes for furniture, household appliances and equipment.

• Independent variable frequency for feeding and stack output – the feeding speed and the stack output speed are independently adjustable through variable frequency, adapting production to the specifications of each job without compromising quality or speed.

• Electric adjustment of the carriage and pressing roller – the paper carriage and the pressing roller are both electrically adjustable in distance directly from the control panel, with no manual intervention with tools, saving time at format changeover.

Technical specifications of the YF-Z Series automatic corrugated board box gluing and bundling machine

The 2 models of the YF-Z Series automatic corrugated board box gluing and bundling machine

1224Z — maximum accuracy ±1,5 mm for medium formats

The 1224Z model of the automatic corrugated board box gluing and bundling machine processes boxes with a front between 250 and 800 mm and a back between 100 and 800 mm, at folding accuracy of ±1,5 mm and a speed of 130 m/min. It is the choice for plants that process medium-format boxes with high geometric accuracy requirements — packaging for technical products, electronics and medium-size industrial products where tight folding tolerances are critical for compatibility with customers' automated filling lines.

1630Z — extra-large format with a front up to 1000 mm

The 1630Z model significantly extends the capacity over the 1224Z: a box front up to 1000 mm and a back up to 1100 mm, with a minimum folding spacing of 400 mm and ±2 mm accuracy. The 1630Z automatic corrugated board box gluing and bundling machine is the solution for manufacturers of packaging for furniture, large household appliances, industrial equipment and any product that requires boxes with a front larger than 800 mm — a format that no other folder-gluer model in the UZINEX portfolio can process.

The YF-Z Series versus the HS-A, HS-B and HS-C series — when to choose differential correction

The HS-A, HS-B and HS-C series are high-speed folder-gluers optimized for medium and small formats, with speeds of 280–350 pcs/min and alignment systems using navigation buoys and variable frequency. The YF-Z Series automatic corrugated board box gluing and bundling machine uses a fundamentally different mechanical architecture — differential correction with independent left-right control and full alignment with linear rails — designed specifically for large-format and heavy boxes where conventional systems generate wobble or incomplete folding.

If the packaged products are heavy (furniture, equipment, metal parts), if the box format exceeds 800 mm front, or if the geometric accuracy of the finished box is critical for the customer's filling line, the YF-Z Series automatic corrugated board box gluing and bundling machine is the correct technical solution, even if the speed in pcs/min is lower than the HS series. UZINEX provides free consultancy for comparing configurations based on specific requirements.

Applications and industries for the YF-Z Series automatic corrugated board box gluing and bundling machine

The YF-Z Series automatic corrugated board box gluing and bundling machine is intended for packaging plants that process large and medium-large format boxes for the furniture, household appliance, industrial equipment, construction materials and heavy technical parts industries. The differential correction system and the linear-rail alignment are designed specifically to handle the rigidity and weight of the triple wall board frequently used in these applications.

Manufacturers of export packaging — where the boxes must withstand stacking on pallets in maritime containers — use this automatic corrugated board box gluing and bundling machine because the geometric accuracy of the folding and the gluing quality are critical for the mechanical strength of the finished box. A box with an incorrectly formed corner or incomplete folding fails prematurely under stacking, even if the board itself is of superior quality.

Packaging plants that serve manufacturers of flat-pack furniture (IKEA-type), large household appliances or HVAC equipment find in the 1630Z model of the automatic corrugated board box gluing and bundling machine the only folder-gluer in the UZINEX portfolio capable of processing boxes with a 1000 mm front and 1100 mm back in a complete automatic flow.

How the YF-Z Series automatic corrugated board box gluing and bundling machine works

1. Suction feeding with active lateral alignment – the pre-die-cut blanks are picked up by suction on the guide edge and fed into the line through the linear-rail structure with a left-right lateral belt; the active lateral alignment function immediately corrects any misalignment at the inlet.

2. One-key format adjustment – the operator enters the box dimensions (length, width, height) directly into the system; the machine automatically reconfigures all stations simultaneously, with no separate adjustments on each module.

3. Folding with synchronized transverse movement – the left-right folding arms move synchronously and transversely together with the deflectors and the gluing mechanism, applying the folding force uniformly to both edges of the box and preventing asymmetry or lateral wobble.

4. Differential left-right correction – the differential correction system independently monitors and compensates the speed on each side of the line, correcting variations in board rigidity or load imbalances on heavy boxes, without stopping production.

5. Box corner forming with multi-channel system – the multi-channel device forms the box corner at exactly 90°, with the bidirectional safety structure preventing incomplete folding on thick board or board with thickness variations between batches.

6. Final full alignment – the full alignment station checks and corrects the geometry of the finished box before output, ensuring that all corners are at 90°, that the flaps are correctly folded and that the gluing is uniform along the entire length of the flap.

7. Pneumatic stacking and automatic bundling – the pneumatic stacking mechanism counts and stacks the boxes according to the set quantity; the pushing time and the stack output speed are independently adjustable through variable frequency for adaptation to the specifications of each job.

Frequently asked questions about the YF-Z Series automatic corrugated board box gluing and bundling machine

What is differential correction and why is it important for large, heavy boxes?

Differential correction is a control system that independently adjusts the transport speed on the left and right sides of the folding line, compensating for differences in the board's mechanical strength. On large, heavy triple wall boxes, even minimal thickness variations between the left and right edges of the sheet can generate lateral wobble or incomplete folding if both edges are pulled with the same force. The YF-Z Series automatic corrugated board box gluing and bundling machine detects and compensates for these variations in real time, maintaining precise alignment without manual intervention.

What is the accuracy difference between the 1224Z (±1,5 mm) and 1630Z (±2 mm) models?

The accuracy difference reflects the difference in format and weight of the processed box. On the smaller formats of the 1224Z model (front max 800 mm), maintaining ±1,5 mm accuracy is achievable with the differential correction system. On the large formats of the 1630Z model (front max 1000 mm, back max 1100 mm), the folding arm works over a greater length, and the cumulative board variations increase the realistic tolerance to ±2 mm. For standard industrial applications with extra-large format boxes, ±2 mm accuracy is more than sufficient and superior to what a conventional folder-gluer can achieve at these dimensions.

What is the concrete difference between the YF-Z (UZX-197) and the HS-A/HS-B/HS-C series — when do I choose each?

The HS-A (350 pcs/min, format up to 1100/1145 mm), HS-B (280 pcs/min, format up to 1000/1000 mm) and HS-C (small boxes, 130/80 mm minimum) series are optimized for maximum speed on medium and small formats, with alignment systems using buoys and variable frequency. The YF-Z Series is measured in m/min (130 m/min) — not pcs/min — because it works on large formats where linear speed matters more than the number of boxes. Recommendation: YF-Z for large (>800 mm front) and heavy boxes where geometric accuracy is critical; HS-A/B/C for maximum speed on medium and small formats. The YF-Z 1630Z model is the only one in the portfolio with a 1000 mm box front.

Why is the speed expressed in m/min on the YF-Z and not in pcs/min as on the other folder-gluers?

For large and extra-large format boxes, expressing it in pcs/min would vary greatly depending on the box size (a 1000 mm box needs more time in the line than a 400 mm one). The linear speed of 130 m/min is a more objective measure of the system's mechanical capacity. With a 1630Z box of 1000 mm front, the practical speed is approximately 80 pcs/min; with a 1224Z box of 500 mm front, the practical speed rises to over 200 pcs/min. This measurement is similar to the one used for integrated printing-folding-gluing lines (UZX-190 HX Folder-Gluer) that process the same large formats.

Can the YF-Z Series process export boxes with strict pallet-stacking requirements?

Yes, and it is one of the main applications of the series. For export in maritime containers, the boxes are stacked on pallets in rows of 5–10 levels, and the cumulative weight on the bottom box can reach 200–400 kg. A box with an incorrectly formed corner (not at 90°) or with incomplete folding fails under stacking even if the board is of superior quality — because the compression force is not distributed uniformly over the box edges. The multi-channel corner-forming system and the differential correction of the YF-Z ensure the perfect geometry needed for stacking strength throughout the complete logistics chain.

For what volumes is the YF-Z Series 1630Z (extra-large format) economically justified?

The 1630Z model is a justified investment for plants that regularly process boxes with a front over 800 mm — typically dedicated manufacturers for flat-pack furniture (IKEA and similar), large household appliances (refrigerators, washing machines), HVAC equipment or bicycles/electric scooters. The economic threshold is related to the percentage of large-format orders in the portfolio: if over 25–30% of the volume involves boxes over 800 mm front, the 1630Z is justified — the alternative being subcontracting for these formats, which is more costly per finished unit. UZINEX evaluates the plant's order profile free of charge for a concrete recommendation.

Is the YF-Z Series machine eligible for EU-funded projects?

Yes. UZINEX is a member of the Enterprise Europe Network and supplies equipment for EU-funded projects — NRRP, the Regional Program, the Just Transition Program. The YF-Z Series is suitable for funding applications with a component for modernizing heavy industrial lines and automating packaging for strategic sectors (furniture, household appliances, equipment). The distinct technical system (differential correction, linear-rail alignment, formats up to 1100 mm) represents a technological-innovation argument in funding applications.
