ものであつた。[Prior Art] Conventional cutting machines for saddle-stitched books use a shear cutting method in which the upper blade is moved up and down relative to a fixed blade to cut the paper. In this method, since the back of the saddle-stitched book is thick, a space is created between the straight lower blade and the back of the saddle-stitched book depending on the thickness of the saddle-stitched book. Since the lower blade could not be brought into close contact with the lower blade, the cutting machine became uneven, which caused so-called back plucking. Therefore, in order to prevent this back binding, a method has been used to eliminate the space by attaching a pillow to the space between the spine of the saddle-stitched book, but although this method provides some improvement, It was difficult to select the appropriate pillow depending on the thickness of the pillow and to replace it.

機を提供しようとするものである。[Problems to be solved by the invention] Therefore, the present invention uses a pillow-shaped cutting blade attached to the lower blade to eliminate the space between the back of the saddle-stitched book and the lower blade, thereby preventing spine plucking. It is an object of the present invention to provide a saddle-stitched book cutting machine that prevents this from occurring and also facilitates the operation of attaching pillows.

る。B. Structure of the invention [Means for solving the problem] The present invention is a saddle-stitched book cutting machine consisting of a fixed lower blade and an upper blade that moves up and down. A pillow-shaped cutting blade with an inclined surface and an elongated hole for guiding a mounting tool in the longitudinal direction is provided so as to be slidable and replaceable so as to overlap with the cutting surface of the lower blade.

Adjust the position of the placing part 4 and set it so that it overlaps with the cutting blade surface of the lower blade, and place the back of the saddle-stitched book on the resting part of the back of the sloped surface of the pillow-shaped cutting blade.The lower blade and the back of the saddle-stitched book The back resting part of the pillow-shaped cutting blade is located in the gap between the book and the lower blade, and there is no space between the back of the saddle-stitched book and the lower blade.
As the upper blade descends, cutting is performed by the upper blade, the lower blade, and the pillow-shaped cutting blade, so that back plucking does not occur.

接合する位置に設定するものである。 The lower blade 1 of the cutting machine is fixed to the cutting machine, and when the upper blade 2 descends relative to the lower blade 1, it can move up and down at a position where it joins the lower blade 1. A pillow-shaped cutting blade 3 is placed on the lower blade 1 so that its cutting blade surfaces overlap.
is installed. The pillow-shaped cutting blade 2 is the third
As shown in FIG. 4, a saddle-stitched book spine resting part 4 is formed with one end having an acutely inclined surface, and is provided with an elongated hole 5 for guiding a mounting tool on the upper surface. The pillow-shaped cutting blade 3 is
Before the cutting operation of the saddle-stitched book 10 starts, the saddle-stitched book 10 is bound in accordance with the cutting dimension l of the saddle-stitched book 10, and is carried by the binding needle 10a carried on the transport guide 7 and guides 8 and 9 provided on both sides. It is located at the back of the saddle stitched book 10 at the cutting positions 12 and 13 according to the thickness of the saddle stitched book 10 (see FIG. 2), and the back part 1 of the saddle stitched book 10 is
1 is set at a position where it joins to the back rest part 4 of the pillow-shaped cutting blade 3 without any gap.

て使用できる。(c) Effects of the invention Because there is a resting part on the back of the pillow-shaped cutting blade that can itself act as a cutting blade in the gap between the back of the saddle-stitched book and the lower blade, the back of the saddle-stitched book is the cause of spine plucking. Since there is no gap between the upper blade and the lower blade, and the pillow-shaped cutting blade itself also performs cutting as the lower blade, saddle-stitched books have no room to move along the cutting blade, and there is no back plucking.
A clear cut will be made. Moreover, since the pillow-shaped cutting blade is provided movably and replaceably, it can be used in a state that matches the size of the saddle-stitched book to be cut.
