1. 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;
wherein each of the warps extend in warp paths between the warp supply source and the take-up device, and wherein 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; and
wherein the air pressure for performing shedding is vacuum/suction air pressure, the vacuum pressure system comprising a plurality of shedding ducts to exert a suction action on individual warps, at least some of the shedding ducts being moveable in a direction towards and away from the warps.
