The PULCHRA double knife jointing guillotine with integrated glue application is based on the heavy and rugged construction of the AFD double knife jointing guillotine and cuts and glues up to 3 veneer bundles per minute under the supervision of one single operator.
constant surface pressure on the veneer bundle during trimming and gluing accounts for precise glue application along the bundle’s edge, even with buckled sliced and rotary cut veneers
high cutting quality and perfect squared-edge cuts due to the swinging knife movement
highest possible level of automation owing to fully automatic trimming, gluing and discharging processes
less space requirements compared to traditional systems
special control modes allow to split up or to double cut veneer bundles
Double-Knife Jointing Guillotine with Glue Application
Computer Control and Format Dimension Storage
The built-in computer, based on a Windows operating system, allows for a selection of programs and operating modes. The positioning control based on a micro processor with storage function for the most common widths accounts for economic optimizing of veneer yield.
Automatic Discharge System
After cutting and gluing, the veneer bundles are automatically taken over by a discharge system and transferred to a roller conveyor for angular out-feed to a fanning station.
Glue Application Heads
The glue application heads efficiently apply the glue in both traverse paths. Glue application occurs within the same clamping as the cutting, thus ensuring even and gap-less glue application, even with wavy and buckled veneers. Chilled, large volume glue pots allow for high operating times without constant refilling.
Glue Application Head
Pre-feeding and Optimization Device
The veneer bundle is manually placed on the pre-feeding device and aligned on the gripper shafts. To optimize veneer yield, the manually operable laser helps position the back knife. The maximum attainable veneer width is thus set and transferred to the computer at the push of a button.
Front and Rear Knives
Both knives cut the veneer bundle in a straight and exactly parallel line. The swinging knife movement trims the veneer edges clean and square-edged. The knives cut against a flexible plastic strip.
The pressure beams press the veneer bundle in a single clamping both for cutting and gluing. The veneer bundle is being cut and glued directly afterwards under constant pressure. This ensures gap-less glue application which is specifically useful when processing buckled veneers. The front and rear pressure beams work individually in continuous mode, whereas they work simultaneously in single mode.
Veneer Bundle Fanning (optional)
For the fanning of pre-glued veneer bundles both in grain and cross-grain direction, thereby keeping the veneer strips from sticking together. The Fanningmaster is commonly used in combination with the Gluemaster glue application machine or the Pulchra double-knife jointing guillotines with built-in automatic glue application. Automated production lines typically rely on these machines.
