7320 roller cutting machine

Cutting Machine in a steel welded construction with an individual number of prep tables

Material and cutting dies are loaded on the cutting board. By pressing the start button the request is stored in the PLC and shown on the touch panel. The cutting boards will be handled in the sequence the start buttons are pushed on related preparation tables.

The guide bar at the transport table is automatically lowered, the transfer devices swing out and the cutting board is manually pushed onto the transport table until its onward movement is undertaken by the transport wheels.

When the cutting board rests completely on the transport table, the lifting device lowers and places the „sandwich“ board onto the cutting dies. The transport wheels swivel and transport the cutting board between the cutting rollers through the machine. Thereby the leather hide is cut continuously.

The sandwich height can be chosen separately for each preparation table (0,1 mm steps) and is controlled via light barrier on infeed and outfeed side of the cutting area.

Once the cutting board has completely passed through the machine, the transport wheels are stopped and steel rollers are changed over for the return transportation of the cutting board. The upper cutting roller is lifted to avoid double cuts. As soon as the cutting board is returned to its initial position under the fi rst lifting device, the sandwich board is removed and the cutting board is partially moved by the driven transport wheels and then manually back onto the preparation table. After removing of the cut parts, the cutting board can be prepared for the next pass through the machine.
