SYSTEM AND METHOD OF MAKING OPEN-ENDED THERMOPLASTIC BELTING
A system and method of making an open-ended, reinforced, layered belt having a profile layer, a top layer material, and tensile cords fully encapsulated there between. The method includes engaging portion of the profile layer on a rotatable cylindrical mandrel (2) with an engaging roller (4), disengaging with a take-off roller (3), and applying and fusing the cords (7) to the profile layer at a desired cord spacing there between. The cord (7) may be fused by melting the profile layer surface with a heated plow and/or with heated cord. The cord (7) is then covered with the top layer material (10) in a lamination step involving heating to melt at least a portion of the top layer and pressing it to fuse it to the reinforced profile layer. Lamination may be done downstream or directly on the mandrel.

The durability of a belt is enhanced by improving the strength of rubber itself while enhancing its peeling strength with respect to a cord, a fabric or a short fiber. A toothed belt (10) comprises a belt body (13) that is integrally formed by a tooth rubber (11) provided on one surface side thereof, a backing rubber (12) provided on the other surface side, and an embedded cord (14) spirally wound in a boundary portion between the tooth rubber (11) and the backing rubber (12) that extends in the longitudinal direction of the belt. A facing fabric (20) covering the tooth rubber (11) is adhered to a surface of the tooth rubber (11), or one surface of the belt body (13). The tooth rubber (11) is obtained by vulcanization-molding a rubber composition including rubber such as HNBR, resorcinol, a melamine compound, silica and the like.

The present invention discloses a tensioner which comprises: a base; a swing arm mounted on the base, rotating about a first central axis with respect to the base; an elastic element positioned between the base and the swing arm, which is used for biasing the swing arm to rotate with respect to the base; a frictional device which is located between the elastic element and the base or the swing arm, for buffering the relative movement between the swing arm and the base, wherein the elastic element exerts along the radial direction a first pressure on the frictional device such that a first frictional force is produced between the frictional device and the base or the swing arm, and the tensioner further comprises a supporting block which exerts along the radial direction a second pressure on the frictional device such that a second frictional force is produced between the frictional device and the base or the swing arm.
