Abstract
A stream of scrap metal strip is continuously compressed in an apparatus comprising a pair of compression rolls and a traveling shear disposed, in that sequence, along a processing path having a substantial vertical component. The process is performed continuously, and there is no need for the process to be interrupted in order to remove strip parts overhanging the entrance to the compression apparatus.
Claims32
A method for compressing scrap metal strip, said method comprising the steps of:
- providing a processing path having an upstream end and at least a substantial vertical component;
- providing a pair of rotatable compression rolls along said path downstream of said upstream end;
- providing a guillotine shear along said path downstream of said pair of compression rolls;
- moving a volume of scrap metal strip downstream along said path toward said compression rolls, under the urging of gravity;
- rotating said pair of compression rolls (a) to compress said scrap metal strip into a slab of compressed scrap metal strip and (b) to feed said slab downstream toward said shear;
- and employing said shear to cut said slab into a plurality of slab portions each composed of compressed scrap metal strip.
An apparatus for compressing scrap metal strip, said apparatus comprising:
- means defining a processing path having an upstream end and at least a substantial vertical component;
- a pair of rotateable compression rolls located along said processing path downstream of said upstream end;
- a guillotine shear located along the processing path downstream of said compression rolls;
- means enabling a volume of scrap metal strip to move downstream along said path, toward said compression rolls, under the urging of gravity;
- said compression rolls comprising means for compressing said scrap metal strip into a slab of compressed scrap metal strip and for feeding said slab downstream toward said shear;
- and said shear comprises means for cutting said slab into a plurality of slab portions each composed of compressed scrap metal strip.
A method for compressing scrap metal strip, said method compressing the steps of:
- compressing a feed of scrap metal strip into a continuous slab of compressed scrap metal strip;
- and shearing said continuous slab into a plurality of slab portions each composed of compressed scrap metal strip.
A method for processing scrap metal material, said method comprising the steps of:
- providing a processing path having an upstream end and a substantial vertical component;
- providing a pair of rotatable rolls along said path downstream of said upstream end;
- providing a guillotine shear along said path downstream of said rolls;
- moving a volume of scrap metal material downstream along said path toward said rolls, under the urging of gravity;
- employing said pair of rotatable rolls to engage said scrap metal material and urge said material downstream toward said shear;
- employing said shear to cut said scrap metal material into pieces of a predetermined size;
- clamping said scrap metal material between said rolls while the material is undergoing shearing;
- and employing the clamping action of said rolls to prevent that part of the material immediately upstream of the shear from kicking upwardly in response to the shearing action.
