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.
