    • The proposed controllable yarn brake for a yarn feed device has actuating elements (10, 11) connected to a control member (12) and designed to ensure controlled movements of the yarn braking element (8), these actuating elements using the axial play of the carrier ring (9) in its mount in a support member (7) to control the tension in the yarn (Y). In a yarn feed device (F) of this type, a slide drive (10, 11, 10', 11', 10", 11") is provided for each direction which the yarn braking element (8, 8') can take and connected to the support member (7); the slide drive for at least one direction of motion is a pneumatic slide drive connected to a pneumatic drive control (12). In a projectile weaving machine the controlled yarn brake engages and disengages in approximate synchrony with another controlled yarn brake; the engagement of the first controlled yarn brake is preferably in advance of the engagement of the second controlled yarn brake. In a gripper weaving machine the controlled yarn brake is disengaged and re-engaged repeatedly during each weft formation.
    • 可控输出制动器的纱线馈送装置,连接在一个控制部件(12)的操作元件(10,11)被设计为螺纹制动元件(8),并在其存储在一个保持部件的轴承环(9)的轴向间隙的受控位移(7) 使用用于控制纱线Y的张力 在这样的喂纱装置的纱线制动器元件(8,8“)的位移(F)包括一个与所述保持构件(7)连接到所述滑动件驱动器(10,11,10”,11”,10”,11" )提供了一种用于运动的每个方向,其中 一个驱动器到气动控制器(12)连接在所述滑动驱动的气动换档驱动器,用于移动中的至少一个方向。 在射弹受控输出制动器关闭大致与一个同样设置控制纱线制动器和接合,其中优选地所述接合发生,导致受控纱线制动器的接合同步。 在一个片梭织机中的每个条目中受控输出制动器被释放数次,并重新接合。
