Abstract
A stripping device for removing waste sheet material from the vicinity of a cutter. In one embodiment, a plurality of pins are mounted to a rotatable drum positioned adjacent a rotary steel cutting die. The die includes knives for cutting a sheet of material into a desired configuration with the waste portion of the sheet remaining wedged on the die. The stripper pins pierce and lift the waste portion of the sheet away from the die. In lieu of a drum, a plurality of hubs mounted to a common shaft may be provided having the stripping pins mounted thereon. In another embodiment, the stripping pins are mounted directly to the rotary cutter. A cam-actuated lever mounted to the rotary cutter is operable to eject the waste sheet portion from the stripping pins.
