ABSTRACT:
The weaving machine includes an electronic control device which can receive a signal for a reverse-motion of the pile warp let-off drive motor from the card dobby via a sensor when borders (plain woven regions) of the fabric are to be produced within the terrycloth material. When the drive motor briefly runs backward, the tension in the pile warp increases, which causes the plate warp tensioning beam to be shifted into the plain weaving position in which a pivoting lever rides up onto a leaf spring. The latter is shifted into the plain weaving position which causes the increased pile warp tension to be produced. If a terrycloth weaving operation is to be returned to, then the drive motor receives an appropriate signal from the card dobby for a brief fast forward motion of the pile warp beam, which causes a lower pile warp tension to be produced again while the pile warp tensioning beam pivots back into the normal position. In this manner particularly regular, loopless borders having sharp or defined edges can be obtained within the terrycloth fabric.
