Terry loom with pile warp length compensation and deflection into back shed

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 wherein said pile warp thread sheet intersects with and crosses through said ground warp thread sheet at a thread crossing location between said first thread supply arrangement and said back shed, and comprising a thread deflecting arrangement that includes a thread deflecting rod extending along a weaving width of said loom system on a side of said ground warp thread sheet opposite said second thread supply arrangement and having said pile warp threads deflected thereon, a shaft that extends along and is pivotable about a horizontal axis, support levers fixedly connected to said shaft and supporting said thread deflecting rod so that said thread deflecting rod rocks pivotally along with a pivoting of said shaft about said axis, and a pivot drive connected to said shaft and adapted to controlledly drive a pivoting motion of said shaft about said axis.
