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).
A loom with a warp thread tensioning device and with a shedding device which has warp threads pretensioned into a first shedding position, furthermore with a lifting device capable of being driven in oscillation and having drivers for the warp threads, and also with control means actuable by means of actuators, in order to bring the warp threads, and also with control means actuable by means of actuators, in order to bring the warp threads selectively into engagement with the drivers which move the warp threads into a second shedding position, wherein said loom has a second lifting device designed as a lifting beam common to all the warp threads, in order to move the warp threads out of the first shedding position into a switching position active for the first lifting device and in order to move nonselected warp threads jointly into the first shedding position as a result of the pretensioning of the warp threads.
