Abstract
A ground warp thread sheet and a pile warp thread sheet are supplied to a shed forming device. Two stop motions on separate planes respectively monitor the pile warp and the ground warp. The ground warp and the pile warp are deflected over a deflecting rod upstream from the shed forming device. The deflecting rod supports the ground warp and directs the pile warp to cross and interpenetrate through the ground warp before being deflected into the back shed. The vertices of the ground warp and pile warp back sheds are thus located on opposite sides of the deflecting rod. The pile warp crosses through the ground warp directly upstream from the deflecting rod, at a steep angle, for example from 45 to 135 °.
Claims22
In a terry weaving loom system including a first thread supply arrangement, a plurality of ground warp threads supplied from said first thread supply arrangement and forming a ground warp thread sheet, a second thread supply arrangement, a plurality of pile warp threads supplied from said second thread supply arrangement and forming a pile warp thread sheet, a shed forming device which receives said ground warp threads and said pile warp threads extending therethrough and is adapted to form a respective open shed of said ground warp threads and said pile warp threads including a back shed on an upstream side of said shed forming device toward said first and second thread supply arrangements and a front shed on a downstream side of said shed forming device opposite said upstream side, a weft insertion device adapted to insert a weft thread into said front shed of said open shed, and a weft beating device adapted to beat-up the weft thread while forming terry pile loops of said pile warp threads,
- an improvement comprising a first thread deflecting element arranged on a pile warp thread path that is followed by said pile warp threads between said second thread supply arrangement and shed forming device, in such a position so that said pile warp thread sheet intersects with and crosses through said ground warp thread sheet at a thread crossing location and is deflected on said first thread deflecting element to said shed forming device, so that a first back shed vertex of said back shed of said pile warp threads is located on said first thread deflecting element.
