  • Patent number: 4056426
    Abstract: Machine for salvaging rolls of paper such as printed business forms having pin feed registration holes along at least one edge includes guide rollers for positioning the paper web over a normally retracted splicing board. The free ends of the paper which are to be spliced are separately and selectively engaged by spaced vacuum tables. A pair of pin bars, each containing at least four spaced perforation engaging pins, are mounted on a splicing bar with a dovetail arrangement that permits rapid and accurate alignment with the paper. A hand actuated lever permits the pin bars to be moved vertically into or out of the web path so that a tape splice can be made very quickly.
