Abstract
A sheet overlap device or apparatus that includes an improved and novel method and means for overlapping of sheets and in particular for overlapping hand towels at high speeds using a vacuum arrangement. The transfer from one vacuum roll to the other is made at the same surface velocity so as to provide better register of the overlap and wherein there will be less likelihood of jamming occurring. The unit includes feed rolls, a fly knife roll, vacuum fed bed roll, pinch or pressure roll, vacuum fed lap roll, vacuum fed tail roll, and retard rolls. In one form of the invention, there is a generally horizontal feed, while in another form of the invention the feed occurs vertically rather than horizontally. By utilizing a vertical rather than a horizontal discharge of the machine, there is the added advantage to gravity helping the discharge from the folding rolls.
