ABSTRACT:
While a book block (P) is nipped between a pair of clamping plates (1a,1b) and passes through processing units (B to D) in succession, perfect book bind processing is carried out. Two or more of the processing units (B to D) have pairs of members (2b,2c;3c,3d;4a,4b) which engage or come into contact with both sides of a back surface of the book block A thickness of the book block is measured by a measuring unit (6) before the book binding processing is started. When a thickness of next book block is measured by a measuring unit during the book bind processing of a previous book block, a control section (7) stores a measured value of the thickness of the next book block in a memory (8). When the previous book block reaches a predetermined position on a conveying path, a gap between the pair of members of the processing unit located upstream of a position of the previous book block is adjusted based on the measured value stored in the memory. Thereafter, a gap between the pair of members of the processing unit located downstream of the predetermined position is adjusted based on the measured value stored in the memory when the previous book block passes through the processing unit. After the book bind processing of the previous book block is completed, a gap between the pair of clamping plates is adjusted based on the measured value stored in the memory.
