Abstract
A paper transfer feed separator automatically separates paper-drive edge tear strips from paper forms along perforations. The paper transfer feed separator may be hand-held and motor driven for removing the paper drive edge tear strips after the paper form is removed from a printer, or the like, or incorporated into a printer so that separation of the edge strips occurs simultaneously with printing on the paper. The frame of the separator causes a divergence in the paths of the body of the form and the edge paper strip to cause separation thereby, eliminating the need for knife blades or other elements requiring maintenance.
