Progressive laser blanking device for high speed cutting

A method of progressive laser cutting for high speed cutting of strips of material, comprising:

• feeding a strip of material from a coil line into an entry pinch roll assembly at a first end of a conveyor;
• feeding the strip of material along said conveyor to at least a second pinch roll assembly at a second opposed end of said conveyor;
• applying tension to the strip by feeding it between a pair of pinch rollers at said entry pinch roll assembly and said second pinch roll assembly;
• and,
• continuously moving the strip along said conveyor while at least two moveable laser heads progressively cut portions of a blank or a cut-out from the strip.

A laser blanking device for rapid speed cutting of a strip of material from a coil stock, said device comprising:

• an entry pinch roll assembly positioned at a first end of a conveyor support frame having a longitudinal axis;
• a second pinch roll assembly at a second opposed end of said conveyor support frame;
• and,
• a pair of opposed pinch rollers positioned adjacent and cooperating with each of said pinch roll assemblies, said pair of pinch rollers capture and apply tension to a moving strip of the coil stock traveling there between;
• wherein each pinch roller rotates at a velocity substantially equal to a velocity of travel of said conveyor;
• and,
• wherein each said pinch roller continually feeds the moving strip along said conveyor while at least two laser heads positioned on support members interposed between said pinch roll assemblies each moves along multiple axes transverse or parallel to said longitudinal axis to progressively cut portions of a blank or cut-out from the material strip.
