moves around roller 64 at velocity v 2 in the direction d indicated in fig1 v 2 is less then v 1 at least when belt 22 presses signature 50 against outer surface 34 tucking blade 70 from a transfer cylinder 72 for example the transfer cylinder disclosed in u s pat no 6 923 753 hereby incorporated by reference herein tucks a signature 50 into jaw gap 46 movable jaw 44 pushes against signature 50 to place folded edge 51 in jaw gap 46 in between movable jaw 44 and stationary part 42 fig2 gripping device 40 holds signature 50 as signature 50 travels around jaw cylinder 30 at velocity v 1 when jaw cylinder 30 reaches a point a in the jaw cylinder rotation cam cam follower interaction may for example cause movable jaw 44 to release signature 50 at a point beyond point a belt 22 presses signature 50 against jaw cylinder 30 belt 22 moving at slower velocity v 2 guides signature 50 along a segment of jaw cylinder 30 between point a and a point b thus due to the difference between v 2 and v 1 folded edge 51 slides out of gripping device 40 after point b belt 22 continues to carry signature 50 away from jaw cylinder 30 at velocity v 2 stationary stripper 90 rests partially in circumferentially extending grooves of jaw cylinder 30 and is positioned to intercept signature 50 as signature 50 travels along outer surface 34 signature 50 slides along stationary stripper 90 to a gap 66 located between belt 22 and belt 62 belt 22 and belt 62 move at velocity v 2 and transport signature 50 along for further processing fig2 shows an enlarged view of gripping device 40 gripping device 40.
