lever with little mass, high mechanical strength, especially schlaghebel for weaving machines

摘要

The lever is constructed of a hub and a lever arm of composite structure which is secured to the hub. The lever arm is made of one or more strips of resin-impregnated carbon fibers cut from a board of like material. The boards are commercially prepolymerized to a predetermined extent. In addition, a loop of carbon fibers can also be used with the strips to form the lever arm. The arm is secured to the hub by a pressing and curing operation or is secured in place by an overlying cover.
