Abstract
This invention relates to a laminated belt for use in a machine which delivers free flowing material into receiving spaces in between filter plugs. The belt of this invention is a lamination of a metal band and a composition strap perforated with a plurality of apertures. This belt travels in part parallel with and adjacent to a garniture tape carrying filter plugs separated by receiving spaces. The composition strap is shaped to conform to the round shape of the filter plugs, and it contacts the filter plugs, urging them against the garniture tape. The belt and the garniture tape are synchronized so that the receiving spaces precisely register with the apertures in the belt, while an independent device delivers free flowing material through the apertures into the receiving spaces. By urging the filter plugs against the garniture tape, the belt holds the filter plugs in this registered position on the garniture tape. Non-apertured portions of the laminated belt screen the filter plugs from exposure to free flowing material.
