ABSTRACT:
Certain steps in the present method of uncoiling and straightening strip material require that the pivotally mounted straightening machine have an inclined position as when operating on rather heavy and thick material. However when operating on thin strip material the pivotal straightening machine is horizontally positioned and substantially the same method steps are performed in passing the strip material to an accumulation pit. Also the coil is contained during operation to prevent uncontrolled expansion of the internal convolutions and stripping of the initial convolutions from the rotating coil and bending the same in a direction reverse to the curvature when on the coil is also contemplated by the method disclosed.
