摘要： Improved apparatus and technique for the circular weft knitting of articles including an improved knitting machine control synchronization system for computer control operation using independently operable, modular components. Needle selection for knit, tuck or float operation is effected by a unique presser cam system which flexes the lower end of compound needles outwardly where they are selectively and magnetically held or released according to a prescribed program to enter one or one set of plurality of cam tracks (3120) depending on the intended function of the needle. The upper end of the needles are positively engaged and held at a prescribed position above the fulcrum (3108) during such selection operation. A modified sinker element (2090) and sinker drive system accommodate an increased range of stitch length control and compensate for variations in yarn elasticity. The yarn knitting cylinder is directly driven by a hollow core motor concentrically arranged with respect to the longitudinal axis (1904) of the knitting cylinder. Finally there is provided an improved laser yarn cutting system.

摘要翻译： 改进的用于圆形纬编编织的装置和技术，包括使用独立可操作的模块化部件的用于计算机控制操作的改进的针织机控制同步系统。 用于编织，折叠或浮动操作的针选择通过独特的按压凸轮系统来实现，所述按压凸轮系统使复合针的下端向外弯曲，根据规定的程序选择性地和磁力地保持或释放复合针，以进入一组或多组凸轮 轨迹（3120）取决于针的预期功能。 在这样的选择操作期间，针的上端被积极地接合并保持在支点（3108）上方的规定位置。 修改的沉降片元件（2090）和沉降片驱动系统适应线圈长度控制的增加范围并补偿纱线弹性的变化。 纱线编织筒由相对于针织滚筒的纵向轴线（1904）同心布置的中空芯电动机直接驱动。 最后提供了一种改进的激光切割系统。
