Large and largest, heavy and heaviest corrugated boxes can only be produced on highest quality machines. To meet these demands, we have been investing in the technology of Jumbo flexo-folder gluers of the model series CONTAINER LINE CL 16/45, CL 20/48, CL 20/50 and CL 20/55 since 1982. And we continue to develop these machines. With more than 120 installations worldwide, we are proud to know that almost all well-known corrugated manufacturer operate these Jumbo machines on a daily basis. We continuously invest in R&D to improve this product line to maintain our leading market position.

For the production of
RSC – Regular Slotted Cases with high-graphics printing of up to 4 colors in a single pass. Heavy board up to triple wall, with inline rotary die cutting. All sealing methods can be used: Glue, stitch and tape.
Four rows of friction rollers accelerate each single sheet from zero to run
speed. The sheet on the bottom of the hopper is pulled onto the friction rolls by an adjustable vacuum, ensuring an accurate feed register.
All adjustments, such as lateral and front stops, backstop, caliper etc. are made rapidly and automatically by the CNC system.
The fed table is fitted with support rolls to reduce friction to the lowest possible level.
High quality print units are a distinction of ours. Print and counter cylinder are built in a 1:1 ratio to deliver 100% repeatability. Highest print quality, also in a multi-color process is achieved with ease. The use of a chamber blade system, laser engraved ceramic anilox rolls allow for meeting even the most discerning quality demands.
This module was developed specifically for processing heavy-duty corrugated board. In this unit we pre-crush the scoring zone to optimize the physical properties of the board to deliver ideal folding results. Of course, the pre-crush unit is adjustable fully automatically.
The slotting units play a very important role in the production of big boxes.
Slots have to be exact and accurate. Scoring has to be perfect. Head adjustment has to be quick, flexible, precise and multifunctional.
The sealing flap has to be cut exactly and the production of a wide variety of box design has to be possible. To achieve this no fixed, or even partially fixed, center head is used.
And, last but not least, „Extended Slotting”.
Many demands on one or two units –We meet them all!
Today, most order require the use of a rotary die cutter. That’s why we spent a lot of time on this unit and Göpfert brought to bear all its rotary die cutting knowledge. The result is a rotary die cut unit with synchrodrive, anvil trimmer, quick-lock die cut cylinder and even „Extended Die Cutting“- Let’s discuss your needs.
The blanks are transferred via flat belts and ant-crush rollers into the folding section. A vacuum transport system guides the blanks slip free into the 90 – 180° folding position to avoid any possible scuffing of the print through relative movements. A patented step-fold belt assures highest run speeds even when running light board grades. This is possible because the blanks are always guided parallel the folding score. Both folding belts, 0 – 90° and 90 – 180° are driven individually by separate servo drives. This allows individual adjustments to counter already any possible gap and fish tailing issues. The machine is equipped with a movable center carrier for large format blanks. Driven side guide belts as well as horizontal form rollers assure highest quality. Access to the folding section within a watch point for quality inspection purposes.
Gluing: A choice of various glue application systems. Inside and outside glue application, glue inspection systems also available.
A servo-squaring unit is available to deliver perfectly accurate taping and stitching sealing methods.
The squaring section has up to four squaring support units; adjustable across the entire working width to allow even for difficult height-to-width ratio squaring.
The squaring speed is individually adjustable according to format and board grade of the box. Thusly the accuracy of the box is influenced to achieve the highest precision. For skip-feed operation the squaring cams are also adjusted automatically to positively influence the setup times.
The Push-Together unit was awarded the FEFCO Innovation Prize.
Output performance can be boosted between 20% to 80%. Depending on the feed length the PTC-unit can adjust the sealing speed when running in tape or stitch mode. This is achieved by running the PTC-unit at a higher rate of speed to close the feed length depending gap between blanks.
Two fully servo-driven sealing unit operates with a high-capacity stitch head., A central lubrication system assures flawless operation applying up to 2,500 stitches per minute. AC servo-drives for transport belts allow for maximum production speeds. An adjustable center transport carrier with driven transport belt assures precise transport during the stitching process. A quick-change tool cuts setup times, further allowing any required maintenance outside the machine. A control system monitors the blank transport to avoid stoppers inside the machine.
The BAHMÜLLER TopSpeedTaper model TST is a fully servo driven unit which runs up to 180 m/min. It is mounted alongside the high-capacity stitching head on a common Support.
All combination sealing methods can be utilized: Glue, tape, stitch.
A well-proven system collates the blanks following the sealing unit in a drying chute. The blanks are transported in shingled fashion across two transport decks to the palletizing unit.
Precision laser Count.
Exact pile positioning of die cut blanks via a newly developed piling unit.
Fast setup vial CNC.
Hold-down elements for glued boxes.
Automatic pallet cycling.
Intermediate pile grid to boost output performance during pallet change.
Systems for empty pallet feeding and cover sheet feeder are available.
