Abstract (en)
[origin: JPH03189031A] PURPOSE: To stepwise feed a web-shaped workpiece by vibrating motion with the pivot of a crank driving assembly and the vibrating motion of a slide which is superposed on a pivoting motion. CONSTITUTION: In a device for stepwise feeding a web-shaped workpiece. a 1st and 2nd workpiece feeding devices are composed through a transfer rod assembly from the same driving shaft 10. In the 1st workpiece feeding device, the web-shaped workpiece 24 is fed by the vibrating motion with the pivot 17 of the crank driving assembly 16 and the 2nd workpiece feeding device is composed by superposing the vibrating motion of the slide 18 on its pivoting motion. In this way, the web-shaped workpiece is stepwise fed.
