Abstract
A wire tension device for winding wire on an asymmetrical core or jig such that wire consumption periodically varies with the angle of rotation. Between the feed coil and the core a tensioning device is formed by two plates arranged parallel at some distance from each other, and are maintained at that distance by two side strips. The gap formed between the plates is closed on one side by a closing member comprising an inlet opening and an outlet opening for the wire and also an inlet for compressed air. One of the side strips is constructed to be gas-permeable.
Claims5
A wire tension device for winding wire, comprising two plates having flat inner surfaces arranged parallel and at a fixed distance from each other, defining a gap therebetween;
- side strips between and connecting said plates;
- and an end closing member connected to said plates and said side strips, said member having an inlet opening and an outlet opening for passage of wire therethrough, and means for passing a flow of compressed gas through said closing member into said gap, wherein at least a portion of one of said strips is permeable to a flow of gas therethrough whereby wire passing through said device is subjected to friction against said one of said strips.
A device as claimed in clam 1, comprising in addition a wheel closely fitting for free movement between said plates in said gap, said wheel having a circumferential edge arranged to permit passing a bight of wire, extending within said gap between said inlet and outlet openings, between a first side strip and the wheel edge, partway around said circumferential edge, and between a second side strip and the wheel edge.
