US 7,500,495 B2 · End binder for a heald shaft

Abstract

An end binder (5) for a heald shaft (1) is formed by a bent sheet metal member (9) which preferably has a U-shaped cross section and which, according to the preferred embodiment, is of high-grade steel. The open side of the U-section faces the shaft rods (2,3). In the hollow space enclosed by the bent sheet metal member (9) shaft rod couplers (28) are secured which are preferably pivotally held. The upper or lower end of the bent sheet metal member forms part of a driving coupler (25) which is situated preferably in a linear continuation of the bent sheet metal member (9) and is a one-piece component with the end binder (5). Such a structure may be manufactured in a simple manner with very small tolerances, and it has a low weight, a substantial stiffness and highly satisfactory bearing properties for being supported in plastic guides.
