Abstract
A device to tear the perforated margins off of a stack of computer paper is described. The device has a base which contains a waste receptacle in one embodiment that will catch the removed margins. The device uses a lower and upper elastic rib in one embodiment and a lower elastic rib only in another embodiment. The clamping mechanism is pivotal and the design is such that a given force on the handle will provide a greater than the given force clamping the paper margins. The clamping mechanism is either activated by hand or by power means, preferably an electric solenoid.
Claims29
A method of removing the margins from a stack of edge driven, continuous feed, computer tractor rail paper, the margins being separated from the paper by a perforated line, comprising:
- providing a rectangular base, said base having a top, a bottom, two length sides and two width sides, the top having a paper glide surface and an elongated edge, said edge being spaced from said paper glide surface and defining an opening for accepting margins of the stack of papers supported by said paper glide surface, said base having an internal removable waste receptacle;
- providing an abutment on said base extending generally in the direction of the axis of said mounting means for engaging said margins of said stack and positioning said stack at a predetermined distance relative to said edge;
- providing an upper elastic rectangular rib and a lower elastic rectangular rib;
- providing activating means to activate and deactivate said upper and said lower ribs into said open and said closed position;
- providing a mounting member comprising an angle member having a handle and said lower rib attached thereto and further having side members attached on each end of said angle member, a pivotal mechanism extending through said side members of said angle members and said width sides of said base to form a pivot axis for the lower rib, such that said upper rib and said lower rib provide a space therebetween in an open position for receiving the margins of a stack of paper and in a closed position said upper rib and said lower rib clamp the margins for tearing against said upper rib:
- placing the margins of said stack between the upper and lower ribs against said abutment;
- activating said activating means such that said margins of said stack are held firmly between the upper and lower ribs;
- tearing said margins along said perforated lines;
- and
- deactivating said activating means whereby said margins are deposited in said waste receptacle.
A device for stripping the margins from a stack of edge driven, continuous feed, computer tractor rail paper, the margins being separated by a perforated line, said device comprising:
- a rectangular base, said base having a top, a bottom, two length sides and two width sides, the top having a paper glide surface, and an elongated edge, said edge being spaced from said paper glide surface and defining an opening for accepting margins of the stack of paper supported by said paper glide surface;
- an upper rib attached to the edge of the top of said base;
- a lower rib;
- mounting means in said base for mounting said lower rib for pivotal movement about an axis wherein said lower rib and said upper rib have a space therebetween in an open position for receiving the margins of a stack of paper and said lower rib and said upper rib, in a closed position, clamp the margins for tearing against said upper rib;
- an abutment on said base extending generally in the direction of the axis of said mounting means for engaging the margins of said stack and positioning said stack at a predetermined distance relative to said edge;
- activating means to activate and deactivate said upper and lower ribs into said open and said closed position, and;
- removable waste containment means in said base.
A device for stripping the margins from a stack of edge driven, continuous feed, computer tractor rail paper, the margins being separated from the paper by a perforated line, said device comprising:
- a rectangular base, said base having a top, a bottom, two length sides and two width sides, the top having a paper glide surface;
- a hardened upper edge attached to the top of said base, said edge being spaced from said paper glide surface and defining an opening for accepting margins of the stack of paper supported by said paper glide surface;
- a lower rib;
- mounting means in said base for mounting said lower rib for pivotal movement about an axis wherein said lower rib and said upper edge have a space therebetween in an open position for receiving the margins of a stack of paper and said lower rib and said upper edge, in a closed position, clamp the margins for tearing against said edge:
- an abutment on said base extending generally in the direction of the axis of said mounting means for engaging the margins of said stack and positioning said stack at a predetermined distance relative to said edge;
- activating means to activate and deactivate said hardened upper edge and said lower rib into said open and said closed position;
- and
- removable waste containment means in said base.
A device for stripping the margins from a stack of edge driven, continuous feed, computer tractor rail paper, the margins being separated from the paper by a perforated line, said device comprising:
- a rectangular base, said base having a top, an open bottom, two length sides and two width sides, the top having two extended arms, a paper glide surface and an elongated edge, said edge bring spaced from said paper glide surface and defining an opening for accepting margins of the stack of papers supported by said paper glide surface;
- a hardened upper edge attached to the edge of the top of said base;
- a lower rib;
- mounting means in said base for mounting said lower rib for pivotal movement about an axis wherein said lower rib and said upper edge have a space therebetween in an open position for receiving the margins of a stack of paper and said lower rib and said upper edge, in a closed position, clamp the margins for tearing against said upper edge;
