Abstract: Device and process for picking up a formable and/or collapsible part (30) that employs the forces of a vacuum (44) and generally distributes the vacuum force uniformly over a large portion of the surface of the part (30). The device preferably provides support for the part (30) at regular intervals, for example using a distributor plate (14) having many small openings (26). The device preferably employs a porous layer (12) such as an open cell foam between the distributor plate (14) and the part (30). The porous layer (12) may perform for one or any combination of the following: further distribute the vacuum forces, cushion the part (30) against the distributor plate (14), or further distribute the support for the part (30).

Abstract: Extrudate 10 materials that are in a formable and/or collapsible state present multiple challenges for cutting into lengths, particularly when the extrusion profile Includes one or more openings 12 (e.g., running the length of the extrudate 10). The invention is directed at apparatus, devices, systems and methods for cutting the extrudate 10. A cut 64 (e.g., and initial cut) into the extrudate 10 is performed using an ultrasonic knife 27 that vibrates at one or more frequencies. Preferably the cut using the ultrasonic knife 27 is a partial cut 64. A further cut through the extrudate 10 may be made using a secondary cutting tool such as a wire cutter 68. The secondary cutting tool preferably creates a final cut 66 through the extrudate profile, for cutting a part to a length. The ultrasonic knife 27 preferably travels In the horizontal direction at a rate faster than the extrudate 10 while cutting.
