Abstract
A device for straightening wire, particularly coiled wire, is disclosed. The device includes at least two banks of rollers that are pivotally mounted with respect to a supporting base.
Claims21
A device for straightening wire from a helically wound coil comprising:
- means for positioning said coil wherein said wire being uncoiled has a coil set lying generally in a plane, the angle of said plane with respect to said helical coil varying along the length of the coil as the wire is uncoiled;
- first means for guiding said wire for longitudinal movement in a first plane, said guide means having at least three surfaces spaced longitudinally from each other and offset laterally from each other within said first plane for contacting and bending said wire upon longitudinal movement thereof, said coil positioning means located adjacent said first guide means;
- second means for guiding said wire for longitudinal movement in a second plane angularly offset from said first plane, said second guide means having at least three surfaces spaced longitudinally from each other and offset laterally from each other within said second plane for contacting and bending said wire upon longitudinal movement thereof;
- and
- means for supporting said first and second guide means, said support means located in a fixed position with respect to said coil, said angle of said coil set varying with respect to said support means during uncoiling of said wire, said first guide means being mounted to pivot freely with respect to said support, said varying angle of the coil set of said wire pivoting said first guide means to maintain a substantially constant angle between said plane of the coil set and said plane of said first guide means while the said angle between said plane of the coil set and said fixed support means varies.

A device for straightening wire having a coil set comprising:
- a supporting base;
- first means for guiding said wire for longitudinal movement in a first plane, said guide means having at least three surfaces spaced longitudinally from each other and offset laterally from each other within said plane for contacting and bending said wire upon longitudinal movement thereof;
- second means for guiding said wire for longitudinal movement in a second plane angularly offset from said first plane, said second guide means having at least three surfaces spaced longitudinally from each other and offset laterally from each other within said second plane for contacting and bending said wire upon longitudinal movement thereof;
- and
- means for positioning a source of wire adjacent said first guide means, said coil set of said wire having an angle with respect to said supporting base that varies over time as the wire is straightened, said varying angle of the coil set pivoting said first guide means with respect to said base to maintain a substantially constant angle between said coil set and said first guide means while said angle between said coil set and said base varies.

A method for straightening wire from a coil comprising:
- positioning a coil for rotation adjacent to a straightening device, said wire having a coil set lying substantially in a plane, the angle of said plane with respect to the device varying along the length of the coil as the wire is uncoiled;
- passing the wire through a first means for guiding said wire for longitudinal movement in a first plane and for bending said wire at least three surfaces upon longitudinal movement of the wire;
- passing said wire through a second means for guiding said wire for longitudinal movement in a second plane angularly offset from the first plane and bending said wire at least three surfaces in said second plane;
- and
- pivoting the said first guide means about an axis to maintain a substantially constant angle between said plane of the coil set and said first plane of said guide means while the angle between said coil set and said straightening device varies during uncoiling of said wire.
