MACCHINA A CONTROLLO AUTOMATICO CON DISPOSITIVO A DEPRESSIONE PER IL TAGLIO DI MATERIALE FLOSCIO IN FOGLIO

摘要

An automatically controlled cutting machine includes a conveyor table having an endless conveyor belt for moving segments of limp sheet material onto the table for cutting. A cutting carriage and blade are mounted for controlled movement over the support surface of the table to cut pattern pieces from the limp sheet material positioned on the surface. A vacuum system holds the material in a compressed state on the surface during cutting, and a sealing carriage is coupled with the cutting carriage to spread an air-impermeable overlay which seals the material when cut. Before the conveyor belt moves the cut segment of the sheet material off of the table, the sealing carriage is uncoupled from the cutting carriage, and the overlay is wound onto a self-retracting roller on the sealing carriage. The carriage is simultaneously drawn by the overlay toward one end of the table where the carriage remains parked as the cut segment moves off the table.
