Abstract
A releasable corner structure for a heddle frame includes a projection carried by a side support, wherein the projection is received in a hollow space of a frame stave and is clamped in position by a clamping screw. The clamped projection is in the form of a flat body formed in one piece with the side support, and defines an outer frame having an opening within which flexible vibration dampers are positioned to lie between the outer frame of the projection and a metallic member that fits within and is spaced from the sides of the frame opening. The metallic member is riveted to a U-shaped sheet-metal casing that is adapted to surround the outer frame with a slight clearance space. Into the open top of the U-shaped sheet metal casing is riveted a rigid ledge member, against which the clamping screw acts. The side support projection is received within the frame stave and is separated therefrom by the vibration dampers, and therefore vibrations between the side support and the frame stave are damped and heddle frame breakage is prevented, especially when the machine in which the heddle frame is installed is operated at high speeds.
