Heddle frame for a high speed weaving machine

摘要

A heddle frame having a pair of hollow laterally extending cross rails and a pair of end braces connected to adjacent ends of the cross rails to form a rectangular frame. A quick release connection is provided between the end braces and the laterally extending cross rails which includes a connector which is fixed within an opening in the cross rail which has means for compressively gripping a projection which extends at right angles from the end brace. The projection has a width which is less than the width of the opening into which it extends and the connector is resiliently connected to the walls of the hollow rail to provide a connection between the end brace and a cross rail which is rigid when not under stress but which permits limited relative movement of the cross rails and the end braces whenever the cross rails are under stress. The resilient connection includes an insert of synthetic material, or an elastomeric material such as polyurethane into which is fitted two or more bushings for the reception of metal fasteners which fasten the insert securely to the wall of the hollow cross rail.
