Abstract
A roller die cutting machine includes a base having a drive roller assembly generally centered thereon between opposing side edges. A first table is located between the drive roller assembly and the first side edge to support a die assembly, and a second table is supported on the base opposite the first table to support a die assembly. A crank is connected through a set of gears to the pressure roller to rotate the pressure roller and to draw a die assembly through the drive roller assembly, to thereby cut stock positioned on the die assembly. A cover on the drive roller assembly includes a pair of inwardly projecting lips which will contact the pressure roller and produce an audible sound as a consumer's hand approaches the cutting location of the pressure roller.
Claims5
A roller die cutting machine, comprising:
- a base having forward and rearward ends, opposing first and second side edges and upper and lower surfaces;
- a drive roller assembly having an operable pressure roller, mounted on the upper surface of the base extending from the forward to the rearward ends thereof generally midway between the side edges, said drive roller assembly operable to rotate the pressure roller and draw a die assembly through the roller assembly to cut stock located on the die assembly;
- said drive roller assembly including:
- a pressure roller rotatably mounted between forward and rearward stanchions for rotation on a longitudinal axis;
- and
- a cover removably mounted between said stanchions and having first and second opposed vertical panels extending downwardly between said stanchions in generally vertical parallel planes, each of said first and second vertical panels having a generally horizontal lower edge extending between said stanchions a predetermined distance above said base upper surface;
- a first table for supporting a die assembly, located between the drive roller assembly and the first side edge;
- a second table for supporting a die assembly, located between the drive roller assembly and the second side edge;
- drive means connected to the roller assembly for rotating the pressure roller to cut stock;
- and
- means on the drive roller assembly for producing an audible signal upon the approach of a human hand a predetermined distance from the pressure roller;
- said means for producing an audible signal including:
- said pressure roller having a cylindrical outer surface of a resilient compressible material;
- a lip projecting from a lower vertical edge of the first vertical panel towards said pressure roller and spaced a predetermined distance from said roller outer surface;
- a lip projecting from a lower vertical edge of the second vertical panel towards said pressure roller;
- said first and second vertical panel lips having an inwardly projecting edge parallel to the outer surface of said pressure roller;
- said cover vertical panels being formed of a resilient flexible material permitting bending of the vertical panels upon contact of a human hand with an exterior surface of the panel and permitting vibration of the lips upon contact with the pressure roller, such that the inward edge of each vertical panel lip frictionally contacts the outer surface of the pressure roller to produce said audible signal upon rotation of the pressure roller;
- said pressure roller outer surface being formed with a material which vibrates the panel lips upon contact therewith to produce said audible signal.
