The invention relates to a method and a device for producing a fabric consisting of plastic strips, and to the fabric itself. Said method comprises the following steps: a) a transversal web (1) comprising transversal plastic strips (1a) which are connected beneath each other by means of a plastic layer (1b) is provided; b) pieces (1c) of the same length of the transversal web (1) are cut and transported to a assembly station (6), where the transversal pieces (1c) of web are introduced perpendicularly to the longitudinal direction of the transversal plastic strips thereof; c) a plurality of longitudinal plastic strips (8) are provided; d) the longitudinal plastic strips (8) are supplied parallel to the assembly station; and e) the longitudinal strips (8) are connected to supplied transversal strips (1c) of web at the assembly station (6) to form a fabric (11, 19), by introducing a plastic melt layer (10) between the longitudinal plastic strips (8) and the transversal pieces of web (1c) during the course thereof through the assembly station (6), and the plastic melt layer is then cooled such that the longitudinal direction of the longitudinal plastic strips (8) extends at an angle to the longitudinal direction of the plastic strips of the transversal pieces (1c) of web.

L'invention concerne un procédé et un dispositif servant à produire un canevas constitué de bandelettes de plastique, ainsi que le canevas lui-même. Le procédé selon l'invention comprend les étapes suivantes : a) fourniture d'une bande transversale (1) comprenant des bandelettes plastiques transversales (1a) reliées entre elles par une couche de plastique (1b) ; b) découpe de tronçons de bande transversale (1c) de même longueur dans la bande transversale (1) et transport des tronçons de bande transversale (1c) à une station d'assemblage (6) où ces tronçons (1c) sont introduits perpendiculairement à la direction d'axe longitudinal de leurs bandelettes plastiques transversales ; c) fourniture d'une multitude de bandelettes plastiques longitudinales (8) ; d) amenée des bandelettes plastiques longitudinales (8) en agencement parallèle à la station d'assemblage (6) ; e) assemblage des bandelettes longitudinales (8) avec les tronçons de bande transversale amenés (1c) au niveau de la station d'assemblage (6) pour former un canevas (11, 19), par introduction d'une couche de plastique fondu (10) entre les bandelettes plastiques longitudinales (8) et les tronçons de bande transversale (1c) pendant leur passage à travers la station d'assemblage (6), puis refroidissement de la couche de plastique fondu de sorte que la direction d'axe longitudinal des bandelettes plastiques longitudinales (8) forme un angle par rapport à la direction d'axe longitudinal des bandelettes plastiques des tronçons de bande transversale (1c).
