One embodiment of the present invention is an endless non-woven tissue making fabric. The endless non-woven tissue making fabric has a machine direction, cross-machine direction, a tissue machine contacting surface, a tissue contacting surface, a first side edge, and a second side edge. The non-woven tissue making fabric comprises a fabric strip of non-woven material comprising at least one layer of non-woven material. The fabric strip has a first edge, an opposing second edge, a machine direction, and a cross-machine direction. The fabric strip may be spirally wound in a plurality of contiguous turns wherein the first edge in a turn of the fabric strip extends beyond the second edge of an adjacent turn of the fabric strip, thereby forming a spirally continuous seam with adjacent turns of the fabric strip. The first edge of the fabric strip overlaps or underlies the second edge in at least one turn of the fabric strip. The spirally continuous seam has a higher basis weight than the fabric strip.
Selon une variante, l'invention concerne un non tissé pour la fabrication de tissu sans fin, ce non tissé ayant un sens machine, un sens travers, une surface de contact machine de fabrication de tissu, une surface de contact tissu, une première bordure latérale, et une seconde bordure latérale. Le non tissé comprend une bande de matériau non tissé comprenant au moins une couche de matériau non tissé. La bande comporte des première et seconde bordures opposées, un sens machine, et un sens travers. Elle peut être enroulée en spirale dans une pluralité de boucles contiguës, sachant que la première bordure dans une boucle s'étend au-delà de la seconde bordure d'une boucle adjacente, formant une boucle intégrée continue à boucles adjacentes du matériau.
