Title (EN) A METHOD OF PRODUCING A SEAM IN DOUBLE-LAYER FORMING FABRICS
(FR) PROCEDE POUR FORMER UNE JONCTION DANS UN TISSU A DEUX COUCHES
Abstract:
(EN) A method of providing a row of loops at each end of a forming fabric, a filter cloth or a similar fabric, said fabric comprising two layers of weft threads with the threads positioned in pairs substantially one on top of the other and warp threads interconnecting said weft layers where the weft threads are permanently removed in a first zone (4) closest to one end edge of said fabric and temporarily removed in a second zone (5) adjacent to said first zone, where a number of weft threads corresponding to the temporarily removed weft threads together with at least one folding thread (7, 8) are drawn in as a warp in a joining machine similar to a loom, and where one of said folding threads is coarse (8) and temporarily replaces the cable intended finally to interconnect the two fabric ends. The method comprises different proceedings depending upon the position of the warp threads in accordance with the weave pattern when they cross the weft threads of the outermost pair preceding the loop itself.
(FR) Procede pour former un rang de boucles a chaque extremite d"un tissu formant texture, tel un filtre ou un tissu similaire, ledit tissu comprenant deux couches de fils de trame, ces fils etant disposes par paires sensiblement l"un au-dessus de l"autre et des fils de chaine reliant lesdites trames, dans lequel les fils de trame sont enleves de facon permanente dans une premiere zone (4) situe plus pres d"un bord extreme dudit tissu et enleves de facon temporaire dans une seconde zone (5) adjacente a la premiere zone, dans lequel un certain nombre de fils de trame correspondant aux fils de trame enleves temporairement, avec au moins un fil de pliage (7, 8), sont tires comme une chaine dans une machine similaire a un metier a tisser, et dans lequel l"un desdits fils de pliage (8) est epais et remplace temporairement le cordon qui doit finalement relier les deux extremites du tissu. Le procede comprend differentes variantes selon la position des fils de chaine conformement au schema de tissage lorsqu"ils croisent les fils de trame appartenant a la partie situe le plus a l"exterieur et precedant la boucle elle-meme.
