A belt construction and method of making the same are provided, the belt construction having opposed sides and comprising a plurality of teeth defining one of the opposed sides of the belt construction and being mainly formed of a first polymeric material that has reinforcing fibers therein, each tooth having opposed sides that are disposed in spaced relation to adjacent sides of adjacent teeth, the belt construction having a land area between adjacent teeth, and a backing member defining the other of the opposed sides of the belt construction, the backing member being mainly formed from a second polymeric material that is initially separate from the material of the teeth. The method comprises the steps of providing a grooved drum, disposing the first polymeric material in a non-cured form thereof about the drum, then subjecting the drum to heat and pressure to cause the first material to be forced toward the drum and exude into the grooves to at least partially form the teeth, then substantially immediately cooling the first material and the drum to stop the curing of the first material so that the first material is generally in a non-cured condition, then disposing the second material in a non-cured form thereof about the first material on the drum, and then again subjecting the drum to heat and pressure to cause the first and second material to be forced toward the drum to complete any remaining unfinished portion of the teeth and be cured together to form the belt construction.

Elastomer waste may be devulcanized without depolymerization to a material capable of recompounding and revulcanization into a product having physical properties essentially equivalent to the original vulcanizate. Devulcanization is accomplished by application of a controlled dose of microwave energy to sized material, preferably in a continuous process.

A belt construction and method of making the same are provided, the belt construction having a plurality of teeth defining one of the opposed sides thereof and being mainly formed of a first polymeric material that has reinforcing fibers therein, and having a backing member defining the other of the opposed sides of the belt construction and being mainly formed from a second polymeric material that is initially separate from the material of the teeth and is substantially free of fibers therein, the materials defining an interface line therebetween with the interface line in each land area having a portion thereof disposed spaced from the tensile member on the side thereof opposite to the side thereof that faces toward the teeth.
摘要:
A method of making an endless power transmission belt and belt made employing such method are provided wherein the belt has a set of driving teeth on each of pair of opposite surfaces thereof and the belt is adapted to be operated to provide a precision driving action employing the driving teeth on either surface thereof due to such belt having a pair of cooperating helically wound load-carrying cords disposed on a precise pitch line associated with all teeth.

摘要:
A system for conveying a fluid through an under-the-ground location and method of making the same are provided, the system comprising a primary flexible conduit for conveying the fluid therethrough and having an outer peripheral surface and an inner peripheral surface, and an outer secondary conduit having at least a portion of the primary conduit removably disposed therein and having an inner peripheral surface and an outer peripheral surface that engages the ground in the under-the-ground location thereof, the secondary conduit having the inner peripheral surface thereof comprising a helically disposed and inwardly directed projection thereof that engages the outer peripheral surface of the primary conduit in a spiral manner and cooperates therewith to define a helically disposed passage that extends therebetween throughout substantially the entire engagement area thereof.
