Elastomer roller

Abstract

The present invention provides a tape-shaped member with excellent non-adhesive or peeling properties and frictional force (grip force) that can be stably applied even to tape-shaped members having different widths, such as labels without a liner and ordinary labels with a liner. Elastomeric rollers that guide the transfer. Focusing on covering the outer layer of the inner layer side elastic member 223 with a silicone resin (covering layer 224) with a lower C hardness (the hardness based on the spring type hardness meter Asker C type specified in the SRIS0101 standard), it has inner layer side elasticity. 223 and the covering layer 224 which is arranged on the outer periphery of the inner layer side elastic member 223 and is in contact with the belt-shaped member. The covering layer 224 is made of silicone resin with a C hardness of 20 degrees or less, and has an inclined peripheral surface 225 in the direction of the opposite side end. The opposite end direction inclined peripheral surface 225 gradually decreases the elastic body roller diameter D1 toward the opposite end 220L on the opposite side to the offset end 220R in the axial direction of the roller shaft 221 .

Description

technical field [0001] The present invention relates to elastomer rollers, especially to platen rollers, pinch rollers and other rollers for transferring linerless labels or ordinary labels with a liner and other belt-shaped parts, especially for transferring linerless labels, etc. Adhesive layer or elastomeric roll that prevents linerless labels from being caught with hard-to-adhesive adhesives. Background technique [0002] A linerless label has been developed that does not use a release paper (so-called liner) that is temporarily pasted on the back side of the adhesive layer of the label. Since the liner that is discarded after use disappears, it is expected to be a resource-saving material. Figure 13 It is a perspective view of a state in which a conventional linerless label 1 is wound into a roll, and the linerless label 1 is as follows: Figure 13 As shown in a partially enlarged cross-section in , it has a label substrate 2, an adhesive layer 3 on the back side, a hea...

Problems solved by technology

In the thermal printer 8 with such an offset structure, sometimes a plurality of strip-shaped members (such as linerless labels 1) with different issuance widths are printed alternately. In the part where the paper label 1 is exposed, the platen roller 17 is in direct contact with the thermal head 16, and the load due to friction increases, making it difficult to accurately transfer the tape-shaped member.
