Abstract
Abstract A flying panel cutoff and punching machine which punches holes in a panel while that panel is being cut from a continuous length of material in a slugless manner. A camming arrangement drives a punch vertically downward while a shearing blade executes the downward and sideways movement used to cut off a panel in a slugless manner from a continuous length of material.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
114 words
A flying panel cutoff and punch device comprising: a slugless cutoff means and actuating means therefor for shearing panels of predetermined length from a continuous length of material; a punch means on said slugless cutoff means for punching holes in a panel; and punch actuating means on said cutoff means for actuating said punch while said cutoff means shears such panel from a length of material so that said punch means and said slugless cutoff means are actuated at the same time, said punch actuating means including a plurality of cams, said plurality of cams including a wedge block on the cutoff means and a retainer cam on a stationary member of the device.
Claim 2
Dependent Claim
114 words
A flying panel cutoff and punch device comprising: a slugless cutoff means and actuating means therefor for shearing panels of predetermined length from a continuous length of material; a punch means on said slugless cutoff means for punching holes in a panel; and punch actuating means on said cutoff means for actuating said punch while said cutoff means shears such panel from a length of material so that said punch means and said slugless cutoff means are actuated at the same time, said punch actuating means including a plurality of cams, said plurality of cams including a wedge block on the cutoff means and a retainer cam on a stationary member of the device.
Claim 3
Dependent Claim
22 words
The device of claim 1 wherein said cams further include a punch driver cam on said cutoff means contacting said wedge block.
Claim 4
Dependent Claim
