CA 2413975

Artificial leather sheet material is made by hydroentanglement of waste leather fibres. A web (28) of the fibres is advanced on a porous belt (8, 9) high pressure water jet heads (13) in a number of successive hydroentanglement steps. Screens (14) are pressed onto the surface of the web (28) between the water jet heads (13) and the web (28). The screens (14) have apertures which allow deep penetration of the water jets into the web (28) whilst thin screen portions between the apertures act to interrupt the jets and limit formation of furrows (30). Deflector plates (19) are provided alongside water jet heads (13) to remove re-bounding water.

L'invention concerne un procédé de fabrication de matière de feuille de cuir artificiel par hydroenchevêtrement de fibres de rebuts de cuir. On fait avancer une bande (28) constituée des fibres sur une courroie (8, 9) poreuse, cette bande étant soumise à un certain nombre d'étapes successives d'hydroenchevêtrement mises en oeuvre par des têtes (13) produisant des jets d'eau haute pression. Des écrans (14) sont pressés sur la surface de la bande (28) entre les têtes (13) productrices de jets d'eau et la bande (28). Un écran (14) comporte des ouvertures permettant une pénétration profonde des jets d'eau dans la bande (28), tandis que de fines parties de l'écran, situées entre ces ouvertures, interrompent les jets et permettent de limiter la formation de stries (30). Des plaques (19) déflectrices situées à côté des têtes (13) productrices de jets d'eau servent à éliminer les éclaboussements d'eau.
