Abstract: A calendar slide includes a hanger that is secured to the slide during the tinning or crimping process in which the slide is secured to the calendar. The hanger has a hole for hanging the calendar or other work piece tinned with the slide and hanger. Advantageously, according to this invention, the hanger does not need to be riveted or staked to the slide for secure attachment. The slide may include at least one through slot into which a leading edge of a roll of hanger material is inserted. The leading portion of the hanger material is severed or cut from the remainder of the roll while it is positioned in the hanger. An edge of the calendar or work piece is inserted between the spaced legs of the slide and initially crimped between the spaced legs. The hanger is severed from the roll either prior to the initially crimping operation, during the initial crimping operation or immediately there after.

Abstract: This invention relates to a method of binding a sheet of paper. The method includes the steps of feeding an end of a sheet of paper to be bound into a partially folded elongate binding strip which defines a longitudinal axis and has two portions angularly disposed to each other, the end of the sheet of paper being fed in a feed direction that is parallel to the longitudinal axis of the binding strip into a region between the two portions and mating the end of the sheet of paper and the binding strip, with the end of the sheet of paper located in the region between the two portions. The method also relates to an apparatus for binding a sheet of paper, according to the method of the invention.
