Loom

摘要

The invention relates to a loom comprising a warp thread tensioning device and a shedding device ( 12 ), which comprises pre-tensioned warp threads ( 4 ) in a first shedding position (F₁). The loom also comprises a lifting device ( 38 ), which can be driven in an oscillating manner, and followers ( 40 ) for the warp threads ( 4 ), in addition to control means ( 46 ) that can be operated by actuators ( 44 ) in order to selectively engage the warp threads ( 4 ) in the followers ( 40 ) and that displace the warp threads ( 4 ) into a second shedding position (F₃). To simplify said loom, a second lifting device ( 48 ), which is common to all warp threads ( 4 ), is provided in order to displace said warp threads ( 4 ) from the first shedding position (F₁) into a selection position (F₂), in which the first lifting device ( 38 ) is active, and in order to displace non-selected warp threads in unison into the first shedding position (F₁) by the pre-tensioning of said warp threads ( 4 ).
