    • There are provided a stitch cam including a first cam (50, 150, 250) in which a stitch size determining cam surface for a large-sized stitch (61, 161, 261) and a receiving cam surface (63, 163, 305) are formed in the same phase, and a second cam (80, 180, 280) which has a common retracting cam surface and in which a receiving cam surface (95, 195, 331) is formed in the same phase as a stitch size determining cam surface for the small-sized stitch (89, 189, 289), and drive means for the first cam and the second cam, wherein the second cam is supported on the first cam in such a manner that when the first cam is shifted in the front-and-back direction by the drive means of the first cam, the second cam is shifted together in the front-and-back direction and also shifted relative thereto in the front-and-back direction by the drive means of the second cam so that the stitch size determining cam surface provided in the second cam can be displaced with respect to the stitch size determining cam surface provided in the first cam, whereby a small-sized stitch and a large-sized stitch are formed in the same course.
    • 提供了一种线圈凸轮,其包括:第一凸轮(50,150,250),其中大尺寸线圈(61,161,261)和接收凸轮表面(63,163,305)的线圈尺寸确定凸轮表面, 形成有相同相位的第二凸轮和第二凸轮(80,180,280),所述第二凸轮具有共同的缩回凸轮表面,并且其中接收凸轮表面(95,195,331)形成为与针迹尺寸确定 用于小尺寸针脚(89,189,289)的凸轮表面以及用于第一凸轮和第二凸轮的驱动装置,其中第二凸轮被支撑在第一凸轮上,使得当第一凸轮移动时 通过第一凸轮的驱动装置的前后方向,第二凸轮在前后方向上一起移动,并且还通过第二凸轮的驱动装置在前后方向上相对于其前后移动 凸轮,使得设置在第二凸轮中的线圈尺寸确定凸轮表面可以相对于线圈尺寸移位 确定设置在第一凸轮中的凸轮表面,由此在相同的过程中形成小尺寸的针脚和大尺寸的针脚。
