  • Publication number: 20150133250
    Abstract: A belt having a tensile cord embedded in the belt, extending in a longitudinal direction and made up of two components: a tensile component and a sacrificed component. The sacrificed component may be broken into a plurality of discontinuous segments. The tensile component provides most of the reinforcement of the belt. The sacrificial component of the precursor cord protects the tensile component from excessive stretching during cord treating and winding, but breaks, melts, or yields during mandrel expansion during the belt molding process, thus preserving the stretchability of the tensile component.

  • Patent number: 8888635
    Abstract: A V-ribbed belt that includes a ribbed surface covered with fabric is provided. The fabric is stretchable in two predetermined directions. A method for manufacturing the V-ribbed belt is also provided. The method includes placing a belt matrix about a mandrel, placing a fabric about the external circumference of the belt matrix which wraps around the mandrel, placing the mandrel inside a shell having a plurality of grooves on the internal circumference, expanding the belt matrix and the fabric toward the internal circumference of the shell and thus pressing the fabric onto the internal circumference having the multi-ribbed structure, and curing the belt matrix with the fabric. The fabric is stretchable to accommodate itself to the multi-ribbed structure.

  • Publication number: 20140287862
    Abstract: 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.
