First mechanical folding, then should be book 1 strapping soothe, for ShuBei rubber subscribes the thickness of the basic agreement to create favorable conditions, make the glue of subscribing machine of the plate clamping institutions reliable work, rubber subscribes ShuBei thickness after consistent, plain founder. Second glue order process in the hollows of glue, thin and even, firm bonding. Prevent side too thick glue, ShuBei incision in the three face higher than cut generated when the book on the big small fault. Back on the rubber in rubber, according to quality standards on thick as far as possible, eliminate three face book ShuBei DaZhou phenomenon when cut. And in the firm bonding, don't try to ShuBei than incision thick, can make the ShuBei with round potential, for three face book was cut machine uniform dimension creates the condition. Three face cut book, not only to adjust according to customer requirement knife rules, keep books size.

4, up and down the sword
Its reason is one thousand jins linking piece pressure to adjust undeserved, pressure is too great, ShuDui back would cock, pressure is too small, ShuDui feet in pressure will uplift, cutting after ShuDui surface appear before the mouth more than normal size size, one thousand jins linking piece height should transferred to ShuDui from the 5 ~ 10 mm; Paper... pine, the upper air much, cutting knife when moving paper books press, cause it smaller than the normal size; Deal with books for 24 h match again for strapping page, conditional with page should press flat; Clip book institutions in send a book car tailgate and workbench not vertical, should be adjusted vertical; Cutting on the high side, causing pressure paper device pressure big, stone, big, paper, the bending deformation is big, reduced cut book height; Cut institutions of books, the path or the book clip bearing wear, make the clip book is send a book before and after when Yang, make books size is differ, should be replaced wear parts, readjust the eccentricity of the bearing, make its clearance consistent.

6, book after cutting askew
The reason for this is send a book after the car door is not parallel with baffle sword, should be adjusted parallel degree; Send a book in car track rollers eccentric adjustment is bad, the large clearance, or so skewed, should be adjusted to car without swinging; Shell and deformation wear on the sword, should be replaced.
7 each pile of books, the first, anchor near the back a barns incision not neat
