Kind Code:
B2
Abstract:
A belt is entrained about the rollers. A belt guide is secured to an inner surface of the belt and is guided by pulleys. The belt guide is formed of a material that has a dissipation factor of tan δ≧0.05 at a resonance frequency of 1 Hz±10% and at a temperature of 50±0.5° C., and a storage modulus of E′≧8.0×106 (Pa) at a resonance frequency of 1 Hz±10% and at a temperature of 50±0.5° C. Another material has tan δ≧0.05 at 1 Hz±10% and at 50±0.5° C., and E′≧8.0×106 (Pa) at 1 Hz±10% and at 50±0.5° C. The belt guide may be formed of a plurality of layers.
