Device for separating perforated strips from paper sheets

A device for separating a narrow strip from a sheet of paper or the like, wherein the strip is joined to the sheet via a frangible tear line, comprising:

• a main body having means for engaging and accurately positioning a sheet of paper or the like placed thereon;
• a top hinged to the main body along one side and adapted to be swung from a first position overlying the main body to a second position away from the main body;
• and
• gripping means on said top and main body for engaging and holding the narrow strip while the sheet is grasped and pulled away from the device, thus tearing the strip from the sheet, said gripping means including an elongate recess or channel in one of the top and main body and a mating elongate blade-like projection having a tapered knife-like edge on the other of the top and main body, said recess and projection being aligned with one another when the top is in its first position and adapted to engage on opposite sides of the strip to securely grip the strip while the sheet is torn away.

A device for separating the perforated transport edge or strip from sheets of computer paper or the like, wherein the strip is joined to the sheet via a frangible tear line and has a plurality of perforations therein, comprising:

• a main body having limit stop means for engaging and accurately positioning a sheet of paper or the like placed thereon;
• a top hinged to the main body at a hinge means along one side and adapted to be swung from a first position overlying the main body to a second position away from the main body;
• means on said top for engaging and holding the narrow strip while the sheet is pulled away from the device, thus tearing the strip from the sheet, said means comprising a clamping blade on the side of the top opposite said hinge means for engaging and clamping a sheet or sheets of paper or the like between the blade and main body when the top is closed over the main body, and a plurality of hook-like teeth on said top projecting therefrom in positions to extend into the perforations in the strip when the top is in its first position, to hold the strip securely in place;
• interfitting guide surfaces on the main body and the top for guiding the top during its closing movement relative to the main body;
• and
• at least one retainer on said main body, extending forwardly over said main body in spaced relation thereto and defining a limiting spacer for limiting the maximum number of sheets which can be inserted at one time into the device.
