CASE LINE – FULLY SERVO-DRIVEN FLEXO-FOLDER GLUER

Special attention was placed on fast setup. For example, all print cylinders automatically zero-position into the operator optimum position. Closing of all units is initiated automatically without operator involvement to make time available for other Tasks.

Following you will find a short description of all modules:

The vacuum lead-edge feeder is equipped with servo direct drive technology for accurate feeding into the machine.
A dust cyclone assures sufficient negative pressure in the vacuum box. All axis’ are CNC controlled. Software and hardware interface to the pre-feeder support highest continuous production speeds. Optionally, the feeder can be equipped with a sheet cleaning unit.

Highest print and register accuracy are achieved using direct drive technology combined with the slip-free vacuum belt transport system. Options, like the Göpfert-developed chamber blade, specially tuned ceramic anilox rolls, various dryer options, print-length correction, print plate angle adjustment or the quick-change anilox roll-change system allow for a highly customized layout of print units to meet every customer-specific demand.
Special high-graphics options, such as the Göpfert ink management system, deliver superior post-print quality which used to be the realm of pure printing machines.

In between the last-down print station and the slotter unit an optional transfer station is available. Via vacuum belt the sheet transported into the slotter/ die cutter unit. This makes for a clear separation of the print to the converting process. Further, a final drying unit can be installed in this section. Equipped as a reject gate version printed sheets can be ejected during production for print quality control.

The Dual Slotter comprises two individual units. The extremely compact design allows for a minimum feed depth while maintaining optimum accessibility. Of course, also the slotting unit is equipped with the direct drive technology.
Specific advantages, like vacuum transport within the slotting unit and a direct-drive glue tab knife make this slotter unique among all flexo-folder gluers. Needless to say, all slotter axis’ are CNC-controlled and run on high-quality ball screws and complex precision guides. The optional Extendo-Slot function reduces the necessity of knife change against Zero.

The die cut unit is based on technology taken from the EVOLUTION RDC, there are no compromises in regard to efficiency, quality and performance.
Options include, quick lock die mounting cylinders and anvil grinding Systems.

The solution for your waste problems!
The module is located prior to the folder gluer. The board is securely held whilst three air knives remove any of the die cut or slotting waste, the sheet is then transported precisely into the folding unit.

Many possibilities and options are available to tailor make your machine to meet your customers demands know and in the future.

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.

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.

The fully servo-driven sealing unit operates with a high-capacity stitch head. A central lubrication system assures flawless operation applying up to 1,250 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.

Customers demand zero defect.
Being able to eject individual blanks at maximum production speed for quality control purposes is the ultimate innovation on a flexo-folder gluer. Your customer demand statistical quality control – no problem at BGM.
Quality inspection devices like glue control, camera systems for print and gap check, as well as RFID inserters from various OEMs can be integrated at any time.

A well-proven system precisely counts and squares the boxes in a drying chute following the sealing process.
Gentle handling of the high-graphic products demands the separation between bundle forming and ejection. Various box styles as well as die cut blanks can be stacked/bundled precisely.
Accumulation within the bundle forming unit assures good bonding of the glue prior to the ejection station. The bundles are gently transported with the assistance of a hold-down system to the strapper.
