2097925 9211412 PCTABS00014 A woven fabric, such as a base fabric for a press felt, which is designed for a papermaking machine or the like has along each one of two end edges a plurality of seam loops (11-14) to be included in a loop seam to form an endless woven fabric. The fabric is characterised in that there is provided, at least at one of the end edges, at least one string of material, preferably in the form of one or more extra yarn threads (30), extended substantially parallel to the above-mentioned one end edge adjacent the regular thread system (V1-V4) of the fabric. The extra yarn thread or threads (30) are woven to only such portions of the seam loops (11-14) as are facing a first side of the fabric, preferably the paper side thereof. In this manner, there is formed in the seam zone a type of extension of the regular thread system of the fabric, whereby the loop seam is conformed to the rest of the fabric to avoid markings in a paper web at the loop seam.
La présente invention concerne un tissé pouvant servir, par exemple, d'ossature de feutre de presse de machine à papier, et comportant le long de chaque extrémité des boucles (11-14) destinées à l'assemblage du tissu pour former une bande sans fin. € l'une au moins des extrémités du tissu, au moins un brin supplémentaire de matériau, de préférence formé d'un ou de plusieurs fils (30), est ajouté parallèlement au bord du tissu, à côté des fils de trame (V1-V4). Le ou les fils supplémentaires (30) sont insérés dans les boucles (11-14) sur une des faces du tissu seulement, de préférence la face destinée à être en contact avec le papier, de manière à assurer l'uniformité de la trame entre la zone d'assemblage et le reste du tissu et à éviter ainsi la formation de marques sur la feuille de papier à cet endroit.
