Abstract
Abstract A method and machine for gathering together in superposed and in exact timed relationship a plurality of webs of paper from independent rolls of paper. The webs on the rolls have a prepunched row of regularly spaced holes extending longitudinally and along at least one edge thereof. Each web is pulled from a roll and is guided to a lower moving endless belt having pins thereon which enter certain of the holes in the web from the under side thereof and pull it into a horizontal position. Each web is passed from one such belt to another to gather the webs into superposed relationship. Eqch web has a slack portion in the form of a festoon therein after it is pulled from a roll, and each web has a frictional restraint at the end of the festoon to maintain the web in taut condition as it approaches a lower belt. There may be an upper moving belt which has pins thereon which enter holes in the webs, from the upper side thereof, and said upper belt extends beyond all of the lower belts and maintains control of the webs continuously while they are moving over the spaced lower belts and also while they are moving between the spaced lower belts. The upper belt may partially overlap another moving lower belt having pins thereon which enter holes in the webs other than those occupied by the pins on the upper belt. The last mentioned lower belt controls the movement of the webs while operations are being performed thereon and discharges them from the machine. The method enables rolls to be prepunched and stored indefinitely under different climatic conditions then selected for use in any number of multi-part forms and gathered together into exact lengths. Additionally, the method permits relatively heavy rolls of paper to be mounted near the floor level and at one end of the machine for convenience and alacrity in handling and replenishment.
