摘要： A sewing machine has a work bearing surface in a substantially horizontal plane and a cutting device for the work including a bottom knife disposed in the horizontal plane of the work bearing surface and a top knife movable in the vertical direction. The cutting device has a toggle lever transmission drive comprising two articulatedly connected connecting rods, the joint of which is connected with a drive element. One of the two connecting rods is connected, at an outer joint thread with the top knife.

摘要： A flexographic printing machine has a printing block cylinder, an impression cylinder and a duct roller that is immersed in an ink trough. The printing block cylinder is rotatably supported by exchangeable bearing blocks that are removably secured to spaced support beds. Each support bed is mounted on an eccentric having a journal which is carried by side plates of the printing machine. The support beds are movable both horizontally and vertically to shift the printing block cylinder between various positions.

摘要： A sewing machine includes a main shaft driving a sewing needle to reciprocate it through the material to be sewn which is fed over a needle slide of a stitch plate. The main shaft also drives a trimming knife drive which drives a reciprocating knife which cooperates with a counter blade adjacent the stitch plate for trimming the material. The trimming knife drive includes an eccentric driven by the main shaft and operating a knife operating linkage connected to reciprocate the knife. An eccentric rod is driven by the eccentric and it drives a swing lever through a guide rod which is pivoted thereto. The swing lever in turn drives the knife through a linkage connected between it and the knife and selectively moves it upwardly and downwardly for stopping its motion in either an upward or downward position. A device is connected to the eccentric rod so as to pivot the swing lever into a position in which it actuates the linkage to move the knife to its cutting position independently of the position of the eccentric.
