Abstract

The present invention discloses a method and an apparatus for producing a woven material from tape-like warps and wefts, comprising a warp supply source for tape-like warps; a shed forming device to form a shed by said warps; a weft insertion device for inserting tape-like weft in the shed formed by said warps; and a take-up device for taking-up the produced woven material. Each of the warps extend in warp paths between the warp supply source and the take-up device. Further, the shed forming device comprises an air pressure system arranged to apply pressure on the face of at least some of the warps in an intermediate position of the warp paths, between the warp supply source and the take-up device, the applied air pressure being sufficient to displace said at least some warps in essentially the thickness direction of the tape-like warps.

Description

technical field [0001] The present invention generally relates to weaving. In particular, the present invention relates to shedding operations in which the displacement of the tape-like warp threads is effected by air pressure. Background technique [0002] The shed is the primary operation in the weaving process. Its purpose is to displace the warp yarns to form the shed. Shedding is the selective shifting of the warp yarns performed at each weaving cycle to create a variety of different weaving patterns such as plain, twill and satin. [0003] Numerous shed methods have been developed over the years. The pedal, cam, dobby, jacquard methods are well known. In all these methods, the shed elements (ie heddles / healds) come into physical contact with the warp threads, regardless of their construction such as yarns, tows, belts, etc. This is because each warp thread passes through an eyelet in the heald frame. [0004] Shed systems have also been developed in which warp ya...
