As shown in FIGS. 4 to 6, the conventional plate winding device for a shaft-wheel printing press has a slit 2 in the longitudinal direction of the plate cylinder 1, and the plate winding device has a slit 2 in the longitudinal direction so as to be located inside the slit 2. Roll-up shaft 3
is inserted, and this plate winding shaft 3 is held between clamp fittings 4, 4 provided on the end face of the plate cylinder 1, and plate winding is performed by tightening the clamp fittings 4, 4 with bolts 5, 5. The shaft 3 is fixed.

巻込み軸３を固定することにより版６が版胴１に
ゆるみなく固定されるようになつている。 The plate 6 has a bent portion 6A at one end formed at an acute corner 2A of the slit 2 of the plate cylinder 1, and a bent portion 6B at the other end formed at a groove 7 formed in the axial direction of the plate winding shaft 3. By rotating the plate winding shaft 3 in the direction of the arrow in FIG. 6, the plate 6 is tightened and brought into close contact with the surface of the plate cylinder 1, and in this state, the bolts 5, 5 are engaged with each other. By tightening the plates and fixing the plate winding shaft 3 with the clamp fittings 4, 4, the plate 6 is fixed to the plate cylinder 1 without loosening.
しかして近時、版６の厚さが従来0.3ｍ／ｍの
ものが0.24ｍ／ｍと薄くなり、版材の節減が図ら

なつて版抜けが生じるという事態を招きやすい。 However, recently, the thickness of the plate 6 has been reduced from 0.3 m/m to 0.24 m/m, and there is a tendency to save on plate materials. The rigidity of the bent portions 6A and 6B of the plate 6 is insufficient, and the locking by the slits 2 and the grooves 7 becomes uncertain, which tends to cause the plate to come off.
本発明はこれに鑑み、薄い版であつても版抜け
が生じることのない版巻込み装置を提供すること
を目的としてなされたものである。
In view of this, the present invention has been made for the purpose of providing a plate winding device that does not cause plate omission even when a thin plate is used.

In order to achieve the above object, the present invention has a plate end inserted into the inner part of a plate end insertion slit formed in the longitudinal direction of the plate cylinder so as to be rotatable along the slit, and one of the plate ends inserted in the axial direction. In a printing press equipped with a plate winding shaft having a groove in which the plate is inserted, a vertical surface portion corresponding to the depth of the groove, a horizontal surface portion bent at a substantially right angle to the lower end of the vertical surface portion, and a A plate edge pressing member having an arcuate surface portion bent in the opposite direction to the horizontal surface portion and curved so as to closely contact the circumferential surface of the plate winding shaft is provided, and this plate edge pressing member is fitted and fixed in the groove. , the edge of the plate is held under narrow pressure between the surface of the plate edge pressing member and the inner surface of the slit of the plate cylinder.
以下、本発明を第１図乃至第３図に示す実施例

同一符号を用いて説明する。
The present invention will be described below with reference to the embodiments shown in FIGS. 1 to 3, using the same reference numerals for parts common to those in FIGS. 4 to 6.
本発明においては、版巻込み軸３の溝７に版端
押え部材８が溝７の長手方向に嵌合固定されてい
る。 In the present invention, a plate edge pressing member 8 is fitted and fixed in the groove 7 of the plate winding shaft 3 in the longitudinal direction of the groove 7.
この版端押え部材８は、前記溝７の深さに相当

形成されている。 This plate edge pressing member 8 has a vertical surface portion 8A corresponding to the depth of the groove 7, a horizontal surface portion 8B bent at a substantially right angle to the lower end of the vertical surface portion 8A, and a horizontal surface portion at the upper end of the vertical surface portion 8A. It consists of an arcuate surface portion 8C that bends in the opposite direction to the plate winding shaft 3 so as to be in close contact with the circumferential surface of the plate winding shaft 3, and is formed of a metal plate or the like.

ている。 The plate end pressing member 8 is fixed to the bottom surface 7B of the groove 7 of the plate winding shaft 3, the inner surface 7C, and the surface of the plate winding shaft 3 with an adhesive. However, by setting the width L of the horizontal surface portion 8B to a size that allows it to fit firmly into the bottom of the groove 7, it can be used without necessarily being bonded. In addition, the direction in which the plate end presser member 8 is fixed is such that its surface portion 8C is aligned with the slit 2 of the plate cylinder 1.
It is located on the side opposite to the inclined inner surface 2B connected to the acute corner 2A. Further, the thickness of the surface portion 8C is set to be sufficient to hold the end portion 6A of the plate 6 under narrow pressure in the gap between the inner surface 2B and the surface portion 8C.
本発明は上記の構成であるから、版胴１のスリ

れる。 Since the present invention has the above-mentioned configuration, the end portion 6A of the plate 6 on the side that easily comes out from the slit 2 of the plate cylinder 1 is connected to the surface portion 8C of the plate edge pressing member 8 and the inner surface of the slit 2.
Since the plate 6 is sandwiched between the plate 6 and the plate 6, it is prevented from slipping out from the slit 2 even if the plate 6 is thin and lacks rigidity.

As explained above, the present invention has a vertical surface portion corresponding to the depth of the plate end insertion groove of the plate winding shaft, a horizontal surface portion bent at a substantially right angle to the lower end of this vertical surface portion, and a vertical surface portion of the vertical surface portion. A plate edge pressing member is provided at the upper end and has an arcuate surface portion that is bent in the opposite direction to the horizontal surface portion and curved so as to be in close contact with the peripheral surface of the plate winding shaft, and this plate edge pressing member is fitted into the groove. Since the edge of the plate is held under narrow pressure between the surface of the plate edge pressing member and the inner surface of the slit in the plate cylinder, even if the plate is thin, the thickness of the surface can be reduced. It is possible to securely hold the plate without the plate falling out simply by selecting the plate edge, and since the plate edge holding member only needs to be fitted and fixed in the groove of the plate winding shaft, it is possible to securely hold the plate without falling out. It can be carried out immediately by fitting and fixing into the stopper groove, and can be easily applied without modifying the plate cylinder of the printing press. Further, since the plate edge pressing member can be easily obtained by plating or the like, it has various effects such as being able to be provided at a low cost.
