  • Patent number: 5284197
    Abstract: A method and apparatus for facilitating a splicer operator's pre-splice preparation and positioning of the leading end of a new web for splicing, in a splicer, to the running web of an expiring roll. The webs both include regular and longitudinally spaced registration marks and identical, repeating and longitudinally spaced patterns.A movable table is used for the initial, off line, pre-splice web preparations. It includes a fixture for guiding the leading end of the new web along a longitudinal path and a hole puncher adjacent to the path. An optical instrument is also mounted on the table and is movable transversely across the path. The optical instrument is spaced longitudinally a preselected distance from the hole puncher. The operator moves the new web along and the optical instrument across the path until a registration mark is aligned beneath the optical instrument. The operator then punches holes in the new web using the hole puncher.
