Abstract:
PCT No. PCT/FR92/00472 Sec. 371 Date Feb. 1, 1993 Sec. 102(e) Date Feb. 1, 1993 PCT Filed May 27, 1992 PCT Pub. No. WO92/21802 PCT Pub. Date Dec. 10, 1992.A web of fibers (4) is conveyed by conveyor-belts (2, 5) which pass around rollers (32 to 43, 60 to 69). Some of these rollers are carried by main carriages (10, 14) which are capable of displacement in reciprocating motion above an apron (8) which moves in a direction parallel to the axes of the rollers and collects the web (4) in the form of a lap. Auxiliary carriages (16, 18) are provided for maintaining the length of the paths of the conveyor-belts (2, 5) at a constant value in spite of the reciprocating movements of the main carriages (10, 14). Each auxiliary carriage (16, 18) is located within a bottom passageway (70) which extends beneath the apron (8) and is separated from the apron by at least one partition-wall (72). The invention is applicable to the manufacture of nonwoven fabrics.
