Description
Face cam 1 and impression cylinder 6 are rotated about fixed axes A and E by a drive powered from the main shaft of the printing press. Cam 1 has profiled groove d. Follower 3 oscillates about fixed axis B and carries roller 7 which rolls and slides along groove d. Link 4 is connected by turning pairs C and D to follower 3 and to link 5 which turns about axis E and has shaped end a. At the moment in the rotation of the impression cylinder when the sheet is ejected, roller b of grip 2 runs onto shaped end a of link 5, grip 2 opens and releases the sheet. At this point, link 5 starts to turn. During the time the impression cylinder stands idle, the grips are open. The grips are closed by a spring (not shown) at the moment the cylinder starts its working movement. $3292$CmL,FD$
