Abstract: The present invention provides a mandrel tool and method for more efficiently and consistently forming various shapes of material. In one embodiment of the invention, a pair of pliers having mandrel jaws that are shaped with a uniform cross sectional area throughout a length of the mandrel jaw is used to replace the traditional tapered mandrel. Because the mandrel jaws have a uniform cross sectional area, the wire, for example, can be wrapped multiple times around the mandrel jaw when it is desired to produce multiples of the same shape. For added versatility, the pliers can have opposing mandrel jaws, with different size cross sectional area.

The machine for making the device has a motor driven, horizontally rotating spool with a spool arm to grip and bend the bar about a generally vertical axis. In manufacturing the V-shaped device, a central portion of the bar is placed against the spool so that the spool's arm can grip the bar for winding the bar about the spool. The bar is then bent an appropriate number of times around the spool to form the coiled spring portion, and thereafter the spool rotated backward a portion of a turn to loosen the coils about the spool. The device can then be removed from the machine and finished into any number of products. An example of use for such a V-shaped device is as an exerciser, exercising being performed by bending the V-arms together against the force of the coiled vertex.
