ABSTRACT:
A trimming apparatus for edge trimming books including a trimmer knife assembly and a conveying apparatus for conveying the books along a path of movement into aligned relationship with the trimmer knife assembly. The conveying apparatus includes a pair of horizontally extending endless conveyor chains positioned in parallel on adjacent sides of the path of movement and including outwardly extending pusher members for engaging longitudinal edges of the books and moving them along the path of movement. A pair of vertically extending guide members are positioned laterally outwardly of the endless chains for engaging the ends of the books and moving them into proper lateral alignment with the path of movement. An endless conveyor belt is associated with the endless conveyor chains for frictionally engaging an exterior face of the books and a drive mechanism acts to simultaneously drive the conveyor chains and the endless conveyor belt in the same direction with said conveyor belt being driven at a velocity slightly less than the velocity at which the conveyor chains are driven to thereby produce a frictional force acting to continuously impel the books toward the pusher members to maintain them properly oriented relative to the path. The specification also discloses an access door support for the apparatus so that the door can be slid horizontally to a partially open position and thereafter swing to a full open position.
