PURPOSE:To enable easy setting of intermittent feed speed as desired along with an easy working and a simple mechanism by employing a flat slide cam for an intermittently feeding mechanism. CONSTITUTION:With upward movement of a slide cam member 11, the cam surface 11b thereof moves from the position indicated by two dot and one dash line to the position as indicated by one dot and one dash line and a pin 8 engaged therewith is pushed up toward the left on the drawing with a roller 9 turning. Consequently, a turret member 7 is turned instantaneously to the left by a half pitch angle of the pin 8 while causing an output shaft 3 to turn instantaneously to the left likewise. At this point, the end at which a cam surface 11c of the slide cam member 11 is formed is located at the position retreated from the moving locus of the pin 8 thereby enabling the turning of the turret member 7 without difficulty. |
