Abstract: A continuous vertical conveyor having a horizontal infeed and a vertically displaced horizontal outfeed and a horizontal platform continuously moving between the infeed and outfeed while supported on staggered transport chains so as to remain horizontal even while making a transition between horizontal and vertical directions of travel. The horizontal platform has an upwardly extending arm and a downwardly extending arm to which the chains are pivotally attached so as to provide stability to the platform. The platform is configured with relieved areas between fingers so that it will interleave with infeed and outfeed conveyors and horizontal supports at the infeed and outfeed stations as it passes through the stations.

Abstract: An applicator for applying patches to a traveling web, such as in a bag forming machine, includes a vacuum cylinder with an outer perforated sleeve, an inner slotted sleeve and a stationary core with shaped pressure chambers for applying patches cut from a roll to the traveling web. Cutting blades are included in the perforate outer sleeve to sever patch material from a roll as the vacuum cylinder rotates. The outer perforate sleeve is replaceable with sleeves of different outside diameters to accommodate different patch locations.
