Abstract

The disclosure relates to a machine for performing trimming operations upon the front and side edges of a book as the book continues to advance through the machine. The machine includes a front edge trimming table which is reciprocated in a horizontal direction and receives a book from an infeed conveyor as the table moves in the direction of the conveyor. As the table continues to move in the direction of the infeed conveyor, the book is clamped to the table and the front edge of the book is trimmed. The machine further includes a side edge trimming table which is reciprocated in synchronism but substantially out of phase with the front edge trimming table. As the front edge table completes its motion in the direction of the infeed conveyor and as the side edge table is about to move in the same direction, the book having its front edge trimmed is advanced onto the side edge table. As the side edge table continues to move in the direction of the infeed conveyor, the book is clamped to the side edge table and the side edges of the book are trimmed. Toward the end of the forward motion of the side edge table, the book is released to a conveyor which advances it from the machine.
