Weaving machine, especially a terry cloth weaving machine

Abstract

In a terry cloth weaving machine in which a horizontal translation of both warp thread systems of the upper shed and of the lower shed, together with the already woven fabric, takes place for the formation of loops and in which an apparatus for tucking or laying-in tucked or laid-in selvedges is arranged at each side of the machine for the fabrication of tucked or laid-in selvedges in the woven fabric, the tucking or laying-in needles of which tuck or lay the free ends or pick ends of the inserted weft threads back into the weaving shed, an apparatus for fixing the position of the apex of the weaving shed at least over the width of the associated tucked or laid-in selvedge is arranged at each of the sides of the machine. Each apparatus for fixing the position of the weaving shed apex comprises two bars or straight-edges parallel to the edge or fell of the fabric and to the apex line of the weaving shed, one of which engages the corresponding tucked or laid-in selvedge from above and the other from below. The straight-edges mutually overlap by a prescribed amount and are arranged sequentially in relation to the length of the fabric in a prescribed spaced relationship in which the straight-edge nearer to the weaving reed approximately coincides with the apex line of the weaving shed as well as with the edge or fell of the fabric and with the point of beat-up of the weft at the fabric fell by the weaving reed. This measure assures that, in particular, the weaving shed in the region of the tucking or laying-in needles always has the same opening, so that the weft thread ends tucked or laid back into the shed can be fixed better and flawless tucked or laid-in selvedges thereby obtained.
