Title: Withdrawal unit comprising pair of soft-faced conveyor belts gripping e.g. extruded sections or cables
Inventor: SCHMEES HERMANN
IPC: B29C48/355
Filed: 1996-11-29
Abstract: A novel belt withdrawal unit is used in e.g. a product processing or sheathing plant. It makes an elongate product comprising a rubber mixture or plastic, e.g. a profile strip or a cable. The two motor-driven conveyor belts run between drums,  enclosing the product between them. In the new arrangement, each belt (5A, 5B) has a drive motor (8A, 8B), connected to a unit (9) containing controllers (10, 11). One motor drives a belt at the required velocity. By means of a controller (11), the other belt is driven at the same speed. To measure the speeds, each belt has a transducer (12A, 12B). Preferably the transducers measure the speeds of the strands (14) away from the product. The speeds are compared in the controller and converted to digital impulses, which moderate the drive motor (8B) speed. The transducer senses marks on the rear of the strand away from the product. The belt(s) have cushioned outer surfaces (6). The desired speed of the first drive motor may be set from measurement of the product speed, or by the degree of product sagging ahead of the belts, as measured by a sensor (13).
