Power transmission belt
First Claim
1. A power transmission belt comprising:
- at least one longitudinally extending rib having laterally spaced, first and second oppositely facing surfaces for reception within a complementary pulley groove;
at least one fiber embedded in the one rib, having a length extending transversely to the longitudinal extent of the one rib, and having a portion projecting outwardly from the one rib beyond one of said first and second surfaces; and
a noise suppressing material applied to the one of the first and second surfaces and the portion of the one fiber to inhibit noise generation between the power transmission belt and a cooperating pulley resulting from relative movement of the transmission belt and a cooperating pulley, one against the other.

Abstract
A power transmisison belt having: at least one longitudinally extending rib having laterally spaced, first and second oppositely facing surfaces for reception within a complementary pulley groove; at least one fiber embedded in the one rib and having a length extending transversely to the longitudinal extent of the one rib, with the fiber having a portion projecting outwardly from the one rib beyond one of the first and second surfaces; and a noise suppressing material applied to the one of the first and second surfaces and a portion of the one fiber to inhibit noise generation between a power transmission belt and a cooperating pulley resulting from relative movement of one against the other.

13. A power transmission belt comprising:
-
at least one longitudinally extending rib having laterally spaced, first and second oppositely facing surfaces for reception within a complementary pulley groove; a plurality of discrete fiber yarns each extending transversely to the longitudinal direction of the one rib and having a portion projecting outwardly from the one rib beyond one of said first and second surfaces; and a noise suppressing material applied to the one of the first and second surfaces and the portions of a plurality of the yarns to inhibit noise generation between the power transmission belt and a cooperating pulley resulting from relative movement of the transmission belt and a cooperating pulley, one against the other. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
