DISTRIBUTOR LAYER

摘要

The invention concerns a distributor layer (14) moving in a reciprocating motion to deposit a web (4) coming from a card, on an output apron (8) to form thereon a lap (62) designed for example for subsequent mechanical bonding. A front conveyor belt (2) transporting the web (4) up to a folding carriage (10) and a rear conveyor belt (5) for supporting the other surface of the web (4) up to a depositor carriage (14) are driven so as to have identical moving speeds (F2, F5) in a pinching zone (20). In the folding carriage (10) the web (4) is deviated (A) by less than 90 degrees to move in a down slope along a section (2c), then a turning (B) more than 90 degrees, first exposed, then being externally supported by a support structure (6a, 5a, 6b). The pinching zone (20) slopes slightly downwards. The web is likewise exposed for the turning in the folding carriage (14) then with external support by an arrangement (3g, 2g, 3h) in a second angular surface. The invention enables to increase the treatment speed of the web without its being deformed in the turns.
