Abstract
A method of preparing continuous label paper from a continuous paper consisting of a label sheet coated with an adhesive on the back side thereof and a support sheet detachably adhered to the back side of the label sheet and which sheets are wider than a finished width of the continuous label paper. The steps include forming a plurality of transfer holes at equal intervals along both lateral edges of the finished width of at least the supporting sheet of the continuous paper, forming slits along the side portions of the supporting sheet at positions corresponding to the finished width of the continuous label paper to define excess width portions laterally outwardly of the slits, cutting cut lines in the label sheet to form label pieces in the label sheet spaced at intervals therealong, cutting edge lines in the label sheet adjacent lateral edge portions thereof at positions where the edge lines do not overlie portions of the support sheet corresponding to transfer holes, and which edge lines have an irregular shape defining projections extending closer to the lateral edges of the finished width of the supporting sheet than the positions of the transfer holes, thereby defining unnec…
