    摘要： A loom operating without a shuttle is provided with a weft selection mechanism and a weft retention mechanism with the former operating to select a weft thread and pass it through the sheds of the loom while the latter mechanism retains and holds the weft thread during loom operation. The weft selection mechanism includes a plurality of pivotable weft selector arms having a weft thread engaged at a first end thereof and an actuating mechanism oprating to drive a second end of the selector arms. A plurality of selector arms is provided with the first end of each of the arms passing through a common point during pivotal movement of the arms. The arms are pivotally mounted intermediate their first and second ends and a selector device is provided to selectively engage the second end of a particular arm with the actuating mechanism driving the arm through pivotal motion, thereby to effect selection of a weft thread. The retention mechanism includes a suction nozzle which engages a selected weft thread and holds the thread by operation of suction force with gripping threads actuated by a lever causing the weft threads to become engaged in the nozzle with the nozzle holding the weft threads while the gripping threads are released therefrom to engage other weft threads which are to be brought into nozzle engagement. The suction nozzle formed as part of the weft thread retention mechanism is transversely movable across the apparatus during operation thereof.

    摘要翻译： 在没有梭子的情况下操作的织机设置有纬纱选择机构和纬纱保持机构，前者用于选择纬纱并将其通过织机的梭口，而后者机构在织机操作期间保持和保持纬纱。 纬纱选择机构包括多个可枢转的纬纱选择器臂，其具有在其第一端处接合的纬纱和用于驱动选择器臂的第二端的致动机构。 多个选择器臂设置有每个臂的第一端在臂的枢转运动期间通过公共点。 臂可枢转地安装在其第一和第二端之间，并且提供选择器装置以选择性地接合特定臂的第二端，致动机构通过枢转运动来驱动臂，从而实现纬纱的选择。 保持机构包括吸嘴，其接合选定的纬纱并且通过操作吸力而保持螺纹，其中夹持螺纹由杠杆致动，使得纬纱在保持纬纱的同时保持纬纱而使纬纱接合在喷嘴中，而夹紧螺纹 被释放以接合要被引入喷嘴接合的其它纬纱。 形成为纬纱保持机构的一部分的吸嘴在其操作期间横向可移动穿过设备。

    摘要： 1,082,435. Weft selection; shuttleless looms. ELITEX, SDRUZENI PODNIKU TEXTILINHO STROJIRENSTVI. Aug. 5, 1965 [Sept. 2, 1964], No. 33488/65. Heading DIE. A weft selector 1 comprises a number of guides 4 which are held in a withdrawn position by pawls 30 and which are spring loaded so that, when a solenoid 34 releases a pawl 30, the guide is allowed to bear against a cam operated slide 14 having tracks 27 which allow the selector to be advanced to the picking position and causes it to be returned for latching by the pawl.
