Abstract
Apparatus for setting the pasting rollers in book casing machines. This setting apparatus features a position indicator 2 that is installed outside the fold-pasting unit 3, to which position indicator 2 a fold angle 1a of a book block 1 can be aligned. When this angle 1a is set to the same height as the indicator, the position of the book block represents the datum zero position of the conveyor. The leading edge 6b of the recess 6a in the pasting roller 6 can then be set, in that the pasting roller drive has a position mark 10 which corresponds to the leading edge 6b of the roller recess 6a, enabling this drive to be brought into register with a mark 7 corresponding to the datum zero position of the conveyor.
Claims18
Apparatus for setting the pasting rollers in a book case machine, the machine having an endless, power-driven conveyor with horizontally oriented saddle plates engaging a book block on a transport path, comprising:
- a pasting unit including a pair of horizontally disposed pasting rollers located on both sides of the path of the saddle plates, the rollers including recesses which are configured with leading edges adapted to fit into the fold angles of a book block:
- first means external to the pasting unit, for indicating when the fold angles of a book block carried by a saddle plate are aligned with a reference elevation:
- second means, coupled to the pasting unit, for indicating when the leading edges of the rollers are in a reference angular position:
- third means, associated with said conveyor, for raising and lowering the saddle plate along said path and stopping the plate when said fold angle is at said reference elevation;
- and
- fourth means, coupled to said second means, for rotating the rollers independently of the conveyor until the leading edges of the rollers are in said reference position when the fold angle is at said reference elevation.
