Claim 8:
9. A method for producing a woven material from tape-like warps and wefts comprising:
providing tape-like warps from a warp supply;
forming a shed by said warps;
inserting tape-like weft in the shed; and
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 forming of the shed comprises applying air pressure towards the face of at least some of the warps in an intermediate position of the warp paths, between the warp supply source and the taking-up, the air pressure being sufficient to displace said at least some warps in essentially the thickness direction of the tape-like warps, wherein the air pressure for performing shedding is vacuum/suction air pressure provided by a vacuum pressure system comprising a plurality of shedding ducts to exert a suction action on individual warps, and wherein at least some of the shedding ducts are moveable in a direction towards and away from the warps.
