RAP 2.21 Left Jogger Cylinder
Outputs 10 and 18
To register each book, an air cylinder pushes
the book into the registration plate during the jog
cycle. This jogging cylinder is located on the left
side of the machine, across from the registration
assembly (Figure 2-26).
The jogger pressure valve increases or de-
creases the pressure to the jogger cylinder de-
pending on the thickness of the books.
