    摘要： Described herein is a material roll feeder that may be used for automatically feeding material into a machine, such as an electronic cutting machine. The roll feeder includes a first portion and a second portion. The first portion may be configured to rotatably support a roll of material and the second portion may define a channel configured to receive and guide material from the roll of material therethrough. The second portion of the roll feeder may comprise guide geometry configured to operably enable a separated section of material that has been separated from the roll of material to move over a top surface of the roll of material.

    摘要： A cutting tool may comprise a blade portion forming a distal end of the cutting tool. The blade portion may comprise a knife edge, and this knife edge may be defined by a grind surface. The blade portion may further include a chamfer surface that intersects the grind surface. The grind surface may be planar and/or the chamfer surface may be planar. A first exterior surface angle, defined as an external angle between respective outwardly facing surfaces of the grind surface and the chamfer surface, may be between about 210 degrees and about 270 degrees.
