Abstract:
A master processing apparatus for use with a pair of removable feed rolls, each carrying a supply of stock material to be unwound, at least one of the stock materials having a layer of adhesive provided thereon, said apparatus comprising:a frame including a first frame portion and a second frame portion movably connected for movement relative to one another between open and closed positions; a pair of cooperating pressure applying structures mounted within said frame, said cooperating structures being constructed and arranged to be positioned adjacent one another in a cooperating pressure applying relationship wherein, when the master with the first and second stock materials on opposing sides thereof and with the adhesive contacting the master is positioned between said cooperating structures, said cooperating structures apply pressure to said master and stock materials as they pass therebetween so as to affect adhesive bonding between said master and said stock materials; one of said pair of cooperating pressure applying structures being mounted on the first frame portion and the other of said pair of cooperating pressure applying structures being mounted on the second frame portion such that (a) movement of the frame portions into their open positions moves the pressure applying structures apart from one another into an open access position to facilitate positioning of the stock materials therebetween and (b) movement of the frame portions into their closed positions moves the pressure applying structures into engagement with one another and into pressure applying engagement with the portion of the stock materials positioned therebetween; and guide structure providing a guide surface constructed and arranged to guide the movement of the pressure applying structures into the engaged position thereof.
