The present invention relates to the seaming of fabrics into endless loops for use as paper machine clothing or as a component therein. A papermaker's fabric is made by spirally winding a woven fabric strip. The fabric strip has first and second lateral edges, along which are a first and second lip, respectively. Each lip has at least one lengthwise yarn woven with crosswise yarns. Adjacent to and inward of the first and second lips on the fabric strip are a first and second gap, respectively, which lack lengthwise yarns but whose crosswise yarns join the lips to the body of the fabric strip. When spirally winding the fabric strip, the first lip is disposed within the second gap, and the second lip is disposed within the first gap, of adjacent turns to form a spirally continuous seam which is closed by attaching adjacent turns to one another.
L'invention concerne un tissu tissé obtenu par enroulement en spirale d'une bande de tissu tissé. La bande de tissu a une première (30) et une seconde (32) bordures latérales, qui sont longées par une première (34) et une seconde (36) lèvres, respectivement. Chaque lèvre a au moins un fil de chaîne (26) tissé avec des fils de trame (28). Un premier et un second espaces jouxtent, respectivement, la première (38) et la seconde (40) lèvres et vers l'intérieur de ces lèvres sur la bande de tissu, qui manquent de fils de chaînes, mais dont les fils de trame joignent les lèvres au corps de la bande de tissu. Lors de l'enroulement en spirale de la bande de tissu, la première lèvre est placée dans le second espace, et la seconde lèvre dans le premier espace des spires adjacentes pour former une couture en spirale continue qui se ferme par fixation de ces spires les unes aux autres.
