Device for transport of multi-layer, edge-perforated imprint-receiving substrates

A device for the transport of multilayer, edge-perforated imprint-receiving substrates comprising

• a flip cover having a support face for a rear layer of a multilayer imprint-receiving substrate, wherein the flip cover is furnished smooth at said support face and exhibits an opening recess;
• a thrust tractor including at least one driven gear wheel and closable by the flip cover and exhibiting a rough braking face disposed opposite the closed flip cover, wherein the flip cover is pressable onto the rear layer of the passing imprint-receiving substrate;
• an endless gear belt guided and lead over the driven gear wheel, wherein the gear belt is furnished with pins on the outside for an engagement into the imprint-receiving substrate, and wherein the opening recess of the flip cover surrounds the pins.

A device for the transport of multilayer, edge-perforated imprint-receiving substrates, which are movable along a curved transport path, with a thrust tractor pair disposed in front of a substrate support in transport direction, as well as with at least one friction roller pair with in each case at least one driven friction roller, by way of which friction roller a pulling force can be transferred, wherein the multilayer imprint-receiving substrate rests with its rear layer on the substrate support, wherein

• the thrust tractor (5) is furnished with a braking element (19) for the front layer (8b) of the multilayer imprint-receiving substrate (8) such that a following first friction roller pair (11) exhibits a driven friction roller (11a), which friction roller (11a) rests at the front layer (8b) of the multilayer imprint-receiving substrate (8), and which friction roller (11a) performs a slightly smaller motion path per time unit relative to a counter friction roller (11b), wherein however a counter friction roller (11b), resting at the rear layer (8a), performs a slightly larger motion path versus the tractor advance path.

A device for the transport of multilayer, edge-perforated imprint-receiving substrates with a thrust tractor, which is disposed in transport direction ahead and in front of a substrate support, and which includes at least one driven gear wheel, where an endless gear belt is guided and lead over the driven gear wheel, where the gear belt is furnished with pins on the outside for an engagement into the imprint-receiving substrate, and wherein there is furnished a flip cover with an opening recess for the pins, wherein

• the thrust tractor (5) exhibits a rough braking face (30), disposed opposite the closed flip cover (28), where, however, the flip cover (28) is furnished smooth at its support face (31) and is pressable onto the entered imprint-receiving substrate (8).
