Abstract
An apparatus for perforating a length of pierceable material which includes a first roller, the length of pierceable material being in engagement with and at least partially circumscribing said first roller; and a second roller disposed in close proximity to the first roller. The second roller, which is provided with a plurality of piercing members, is movable from a first position wherein the piercing members are spaced apart from the first roller to a second position wherein selected ones of the piercing members pierce the length of pierceable material. Uniquely, the first roller has a plurality of transversely spaced grooves that receive the extremities of the piercing members when the first roller is in the second position.
Claims12
An apparatus for perforating a length of pierceable material comprising:
- (a) a first roller, the length of pierceable material being in engagement with and at least partially circumscribing said first roller;
- and
- (b) a second roller disposed in close proximity to said first roller, said second roller having a plurality of piercing members and being movable from a first position wherein said piercing members are spaced apart from said first roller to a second position wherein selected ones of said piercing members pierce the length of piercable material.
An apparatus for perforating a length of pierceable material comprising:
- (a) a support;
- (b) a first roller rotatably carried by said support, said first roller having a plurality of transversely spaced apart ridges defining a plurality of transversely spaced apart grooves;
- (c) a second roller rotatably carried by said support in close proximity with said first rotatable roller, the length of piercable material extending between said first and second rotatable rollers, said second rotatable roller having a plurality of transversely spaced apart rows of piercing members and being movable from a first position wherein said piercing members are spaced apart from said first rotatable roller to a second position wherein selected ones of said piercing members pierce the length of piercable material and extend into said grooves of said first rotatable roller.
An apparatus for perforating a length of pierceable material comprising:
- (a) a support;
- (b) a first roller rotatably carried by said support, said first roller having a plurality of transversely spaced apart ridges defining a plurality of transversely spaced apart grooves;
- (c) a second roller rotatably carried by said support in close proximity with said first rotatable roller, the length of piercable material extending between said first and second rotatable rollers, said second rotatable roller having a plurality of transversely spaced apart rows of piercing members and being movable from a first position wherein said piercing members are spaced apart from said first rotatable roller to a second position wherein selected ones of said piercing members pierce the length of piercable material and extend into said grooves of said first rotatable roller;
- and
- (d) a drive system operably associated with the length of piercable material for controllably moving the length of piercable material between said first and second rotatable rollers.
