An elastic body roller which has an excellent non-stick property or release property, and frictional force (gripping force) and is able to stably feed and guide a belt-shaped member such as a linerless label, a typical liner label, or the like is provided. Attention has been paid to coating an outer layer of an inner layer elastic material member (23) having a silicone resin (a coating layer (24) with a C hardness (hardness by a spring-type Asker C type defined in the SRIS 0101 standard) set low. An elastic material member (22) of an elastic body roller has an inner layer elastic material member (23) provided on the outer periphery of a roller shaft ( 21) , and a coating layer (24) provided on the outer periphery of the inner layer elastic material member (23) and being in contact with a belt-shaped member, and the coating layer (24) is formed from a silicone resin with a C hardness of 20 degrees or less.

A banknote stacking apparatus includes a banknote stacking plate 1 on which banknotes are to be stacked, a first banknote press plate 11 fixed to a support shaft 10 so as to be swingably together with the support shaft 10, a second banknote press plate 15 which is formed of a synthetic resin sheet having flexibility, whose upstream end portion is fixed to the banknote stacking apparatus and whose downstream end portion is fixed to the first banknote press plate 11 and a solenoid 27 for driving the first banknote press plate 11 and the banknote stacking apparatus is constituted so that when a banknote is fed into the banknote stacking apparatus and the first banknote press plate 11 is driven by the solenoid 27, the first banknote press plate 11 is swung and presses a portion of a banknote close to the front end portion thereof and the second banknote press plate 15 is swung together with the first banknote press plate 11 and deformed so as to form a convex portion 15c projecting toward the banknote, whereby a portion of the banknote close to the rear end portion thereof is pressed by the convex portion 15c of the second banknote press plate 15. According to the thus constituted banknote stacking apparatus, a banknote can be stacked on the banknote stacking plate 1 in the desired manner using a single drive means.

The invention provides a feed/transport roller formed of polyurethane material, which roller has high wear resistance as well as low hardness for providing excellent sheet feeding capacity and which meets a recent requirement; i.e., high durability for allowing high-speed operation. The feed/transport roller has an elastic layer formed of a castable polyurethane produced through reaction of a polyester-polyol having a number average molecular weight of 1,000 to 3,000 with a polyisocyanate, wherein the elastic layer is formed from the polyester-polyol, the polyisocyanate, an adipic acid ester derivative serving as a plasticizer, a short-chain diol having a molecular weight of 70 to 120 serving as a chain-extender, and a triol having a number average molecular weight of 3,000 to 5,000 serving as a cross-liking agent.

The present invention relates to paper feed rollers required to transfer papers in printers, facsimiles, copiers, etc. with accurately, and provides novel paper feed rollers which are lighter, less expensive and mass-producible with larger diameters as compared with conventional paper feed rollers. The paper feed roller according to the present invention includes a rotary shaft, a cylindrical roller portion formed by press molding a mixture of a hydraulic composition, followed by curing and hardening, and integrated with an outer periphery of the rotary shaft.

An elastic roller includes an inner layer side elastic member around a roller shaft, and a coating layer surrounding around the inner layer side elastic member, the coating layer contacting a belt-shaped member. The coating layer is made of silicone resin having JIS-C hardness of 20 degrees or less. A base layer (23a) and an intermediate layer (23b) of the inner layer side elastic member (23) have JIS-A hardness of 30 to 80 degrees. The rubber hardness of the base layer (23a) is higher than the rubber hardness of the intermediate layer (23b). The intermediate layer (23b) has tearing strength of 25 N/mm or more, the tearing strength being measured using an unnicked angle-shaped test piece in accordance with JIS K 6252. The intermediate layer (23b) has internal grooves (31) having a groove angle of 40 to 160 degrees and having a V-shaped cross section.
摘要:
A web processing method and apparatus for processing a tube shaped web material (16) into one or more sheets (18, 19), e.g. two sheets, of the web material which are forwarded through the apparatus in parallel. The apparatus comprises means (3, 11) for introducing pressurised ionised air into the area between two essentially parallel and opposing surfaces of the web material. The means for introducing ionised pressurised air are integrated into the body part (3) of an edge slitting knife, preferably made of a polymer, such as homo or copolymers of PET, PET-P, HD-PE, PP, PEEK, PSU or mixtures thereof onto which an air ioniser (11) based on AC or pulsed DC technology is connected to a pressurised air inlet (1) of the knife body for ionising the air to be passed to the air nozzles (6) of the knife body (3). Alternatively an ionising air bar (20) is applied between two sheets of web (18, 19). Reduced wear on the knife body part (3) is obtained and electrostatic effects acting on surfaces of the web (16, 18,19) facing each other is neutralised or controlled in order to reduce the tendency of the web to cling to apparatus parts and/or to itself or to the other web sheet.
