    • 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).

    • In a method for controlling the tension of a warp for production of a textile with the number of crossing of the warp with respect to the weft smaller in one part compared with the other part of the textile in the width direction, a warp (3) corresponding to one part with a small number of crossing and a warp (2) corresponding to the other part with a large number of crossing are drawn out from a warp beam (4) and are placed on different rolls (5,6), and the roll (6) dedicated to the warp (3) corresponding to one part is movably provided in the direction crossing with the axis of the roll (6). The method includes the steps of: temporarily reducing the tension of the warp (3) corresponding to one part via the dedicated roll (6) immediately before beating; increasing the tension of the warp (3) corresponding to one part via the dedicated roll (6) after beating so as to regain a target tension value; detecting the position of the dedicated roll (6); calculating the deviation of the detected position and a preset target position; and correcting at least one of the degree of reducing the tension and the target tension value so as to decrease the deviation.
    • 在纺织品生产的经纱的张力控制方法中,与织物的宽度方向的其他部分相比,经纱相对于纬纱的交叉次数在一个部分中的交织数量较小, 对应于具有少量交叉的一个部分,并且对应于具有大量交叉的另一部分的经线(2)从经轴(4)被拉出并被放置在不同的辊(5,6)上,并且 专用于对应于一个部分的经纱(3)的辊(6)可在与辊(6)的轴线交叉的方向上可移动地设置。 该方法包括以下步骤:在打浆之前,暂时通过专用辊(6)临时减小对应于一部分的经纱(3)的张力; 在打浆之后通过专用辊(6)增加对应于一部分的经纱(3)的张力,以便重新获得目标张力值; 检测专用卷轴(6)的位置; 计算检测位置和预设目标位置的偏差; 并且校正减小张力和目标张力值的程度中的至少一个,以便减小偏差。
