  An object of the present invention is to solve the above-described problems and to change the printing surface even if the thickness of the space formed between the printing portions of the endless printing belt main body is increased. Rotation mark that makes it possible to sense the moderation when performing the printing process and that the printing parts of the endless printing belts that are lined up are aligned accurately so that it is not necessary to visually recognize the change in the printing surface. It is an object of the present invention to provide an endless printing belt.

The endless printing belt for rotating stamps of the present invention that has solved the above-mentioned problems is a rotating belt in which a large number of printing portions are arranged with spaces between each other on the surface of a printing belt main body made of a porous material at least on the front side. In the endless printing belt for printing, the surface of the printing belt main body is a non-porous surface that is melt-processed leaving only the printing portion as described above in a porous state, and both ends are dams at intermediate positions of the space portions. A groove in the width direction formed in the portion is formed .
Note that you Keru printing belt body endless printing belt rotary stamp described above is of a laminated belt land that particle course the ink flow resistance reinforcing backing fabric on the back surface of the thermoplastic resin belt locations porous with numerous interconnected pores The surface layer is made of a melt-processed non-porous surface that leaves a porous printed part and is a thin melt-processed laminated belt with a thickness of 2.0 mm or less. It is preferable to raise it. The width direction of the groove which is formed in an intermediate position of each space portion is necessary to both ends and having a dam for increasing the strength of the thin melt processing the laminated belt on top to prevent Tsutai ink In particular, it is preferable that the top of this dam part is flush with the surface of the space part .

  In the present invention, at least the front side of the print belt main body made of a porous material has a surface on the surface of the print belt body, and a large number of print portions are arranged with space portions between them. Since the groove in the width direction is formed, when the portion where each printing portion is formed by the printing surface changing operation passes through the bridge portion of the rotation mark frame, the space portion thinned by the groove is formed. Since the intermediate back is located at the corner of the bridge, the operating resistance changes, and the user can feel the moderation feeling due to the fluctuation of this operating resistance, so there is no need to visually check the change of the marking surface, and this The concave grooves also serve as a guide when aligning the print portions of the endless print belts.

Further, since a certain surface of the space portion in the rotary stamp for endless printing belt as nonporous surface, the intensity is enhanced in terms of ink wetting from this space portion surface is eliminated so that the durability is increased. Further, for preventing the Tsutai ink to prevent the ink that has entered the both ends of the concave groove in the width direction are formed at an intermediate position of each space portion to the groove reaches the back side from both ends of the belt body If it is used as a dam part, ink will not flow out from the dam part and the surroundings will be less likely to get dirty. In addition, the dam part has the advantage of increasing the strength. It is necessary to provide a very short dam part that does not hinder the performance and feeling of moderation, and the height of such a dam part prevents ink transfer effect, moderation feeling, strength, and all manufacturing conditions. In consideration, it is preferable that the top portion of the dam portion is substantially flush with the surface of the space portion.

In the following, as a preferred embodiment of the present invention, an endless print belt for rotation marks used for a rotation mark incorporated in the rotation mark with a master mark shown will be described.
In FIG. 4, 1 is a rotation mark body with a master mark, 2 is a rotation mark, 3 is a master mark in which the rotation mark 2 is incorporated, and a shaft 21 is installed in the middle of the rotation mark frame of the rotation mark 2 described above. An endless printing belt for rotational marking according to the present invention is suspended between a plurality of rotors 22 pivotally supported on the bridge and a bridge portion 23 provided at the lower end of the rotational marking frame.
As shown in FIGS. 1 and 2, the print belt main body 24 of the endless print belt for rotation stamp according to the present invention has a surface layer of a porous thermoplastic resin belt base 24a having countless continuous pores such as foamed polyethylene resin. As shown in FIG. 4, the surface layer of the laminated belt with the ink flowability reinforcing backing cloth 24b layered on the back surface thereof is melt-processed to leave the porous print portion 52 and the space between the print portions 52 and 52. A thin melt-processed laminated belt having a thickness of 2.0 mm or less with a melt-processed non-porous surface including the portion 51 and the entire surrounding portion is provided.

Further, in the space portion 51 formed between the print portions 52 and 52 of the endless print belt main body 24, the concave groove 25 is formed in the width direction at an intermediate position that divides the space portion 51 between the print portions 5 and 5. Is formed. As in the reference example shown in FIG. 1, if the concave groove 25 is a communication groove whose both ends reach the both end edges of the print belt main body 24, ink transfer may occur from both ends . In addition, it is assumed that both ends of the concave groove 25 are dam portions 53 for preventing ink transfer. When the dam portion 53 is provided in this way, the length of the dam portion 53 is extremely short, for example, about 0.5 to 1.0 mm, and the height of the dam portion 53 is the surface of the space portion 51. To some extent on the same plane. By providing the concave groove 25 in this way, it is positioned at the corner of the bridge portion 23 when rotating to change the print surface of the print belt main body 24, and is visually recognized based on the sense of moderation due to the change in the operation resistance. It is possible to feel that the marking surface has been changed without doing so, so that it is not necessary to visually recognize the marking surface every time a rotation operation is performed. In addition to the effect of preventing ink transfer, which is the original function of the dam portion 53, by providing the dam portions 53, 53, it is necessary even if the groove 25 is thinned by the reinforcing effect of the dam portions 53, 53. Strength can be maintained. It should be noted that the grooves 25 and the dam portions 53 and 53 are preferably made non-porous by melting processing or coating processing in the same manner as the space portion 51.

  The above explanation is only for the endless print belt for rotation marks used for the rotation mark incorporated in the rotation mark body with the master mark. However, at least the front side has a large number of prints on the surface of the print belt body made of a porous material. Of course, endless printing belts for rotation stamps that are spaced apart from each other are effective as endless printing belts for all rotation markings as long as they are within the range of known materials and applications. .
