How does it work?

The system can be configured to meet the needs of the customer (in terms of quantity, flexibility, floor space available in the company, and integration with pre-existing IT systems).

 The classic configuration is to insert a roll holder into the line and then cut a number of plies that is equal to the number of rolls. This configuration, which is one possible option, has a number of defects, however, including the fact that various rolls can have different heights, lengths, and colours. Moreover, the phase dedicated to preparing all the rolls equals significant downtime in production, without the flexibility needed to pass from one material to the next or from one order to another.

Phase 1 (Planning)

reportA dedicated software is used to plan production:

  • Order entry or order import from the ERP system of the customer
  • Completely automated placement (nesting) in accordance with material properties
  • Printed report (a printed sheet with barcodes for every multi-ply spread that must be prepared).

Phase 2 (Spread preparation)

The spreads can be prepared using the company’s pre-existing machinery or by using the compact, inexpensive and flexible system supplied by Comelz (roll holders, electric trimmer, and spreading table with centimetre precision and an alignment system).

Phase 3 (Spread cutting)

At this point, there is no need for manual repositioning by the operator, and while the machine continues to cut and work without any downtime, the operator is free to begin reading the barcode and positioning the next spread on the Ply-Shifter for loading onto the machine.

Once the pieces have been cut by the machine, a sole operator can easily unload them: also in this case, just one operator is needed.
