Abstract

Ground warp and pile warp thread sheets are supplied to a shed forming device. The ground warp and the pile warp are separately 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 deflecting the pile warp into the back shed. The deflecting rod is positively driven and controlled to pivot about a horizontal axis to provide a positive controlled partial compensation of the pile warp thread length variations. The pile warp also runs over a pile warp thread reserve and compensating device upstream from the thread crossing location to provide an additional passive uncontrolled compensation of the pile warp thread length variations and to provide a pile warp thread reserve during the pile loop formation and/or the shed changes in the weaving process.
