Abstract
Improvements have been devised in wire straightening and cutting apparatus to the end of protecting the external coating on the wire as it is advanced, straightened and then cut to a predetermined length and are specifically directed to the novel arrangement of feed rollers upstream of a bending spindle to positively force the wire through the bending spindle, demagnetizer and cutter section in such a way as not to damage the external surface of the wire or remove any coating on the wire. A cutting mechanism is correlated with the driving of the feed rollers to cut the wire, once straightened, into predetermined lengths; also, the length of wire cut can be varied simply by varying the speed of the cutter relative to the speed of advancement of the wire.
Claims18
In a wire straightening and cutting apparatus adapted to cut wire of varying lengths from a supply source having a continuous length of wire, wire feeding means for advancing said continuous length of wire in a lengthwise direction from said supply source, wire straightening means downstream of said feeding means through which said continuous length of wire is advanced, and guide means downstream of said wire straightening means to permit said continuous length of wire to float unrestrained from said wire straightening means, and a cutter mechanism including a cutter blade and rotary drive means for rotating said cutter blade in correlated relation to said wire feeding means including means to vary the speed of rotation of said cutter blade in relation to the rate of advancement of said wire as established by said feeding means in regulating the length of wire which is cut by said cutter blade.
A wire straightening and cutting apparatus adapted to cut wire of varying lengths from a continuous length of wire, said apparatus comprising:
- wire feeding means for advancing said continuous length of wire in a lengthwise direction at a location upstream of said wire straightening and cutting apparatus, straightening means downstream of said feeding means for rotating and straightening said continuous length of wire as it is advanced therethrough, a wire demagnetizer downstream of said straightening means, and guide means between said wire straightening means and demagnetizer means to float said wire unrestrained from said wire straightening means through said demagnetizer;
- and
- a cutter mechanism including a cutter blade and rotary drive means for rotating said cutter blade in correlated relation to said feeding means, an anvil on one side of said wire opposite to said cutter blade to support said wire as it is being cut by said cutter blade, and means to vary the speed of rotation of said cutter blade in relation to the rate of advancement of said wire in regulating the length of wire which is cut by said cutter blade.
