Abstract
A distributor layer moving in a reciprocating motion to deposit a web coming from a card, on an output apron to form thereon a lap designed for subsequent mechanical bonding. A front conveyor belt transporting the web up to a folding carriage and a rear conveyor belt for supporting the other surface of the web up to a depositor carriage are driven so as to have identical moving speeds in a pinching zone. In the folding carriage the web is deviated by less than 90 degrees to move in a down slope along a section, then a turning of more than 90 degrees, is first exposed, then is externally supported by a support structure. The pinching zone slopes slightly downwards. The web is likewise exposed for the turning in the folding carriage then with external support by an arrangement in a second angular surface.
