Abstract (en)
[origin: US5061096A] A device for the transport of multilayer, edge-perforated imprint-receiving substrates (8) takes into consideration a curve-shaped transport path (9), wherein a thrust tractor pair (5) is disposed in front and ahead of a substrate support (2), as seen in transport direction (10). Several friction roller pairs are following to the thrust tractor pair (5). In each case, a pulling force is transferrable by way of at least one friction roller. The multilayer imprint-receiving substrate (8) rests with its rear layer (8a) on the substrate support (2). A tearing of the edge perforations of the imprint-receiving substrate (8) as well as belly and bulge formations of one of the two layers (8a, 8b) is avoided by furnishing the push tractor (5) with a braking element (19) for the front layer (8b). A following first friction roller pair (11) rests with a driven friction roller (11a) at the front layer (8b). This friction roller (11a) performs a slightly smaller motion path per time unit relative to the counter friction roller (11b). However, the counter friction roller (11b), resting at the rear layer (8a), performs a slightly larger motion path relative to the tractor advance path.
