Apparatus and method for bonding facing to insulation

摘要

Production machinery applies heat fusible protective films to fibrous insulation rolls or batts. The insulation is passed through a conveyor with upper and lower conveyor belts which pinch the insulation therebetween and which urge protective films into contact. The conveyor belts are heated by proximate heater apparatus to a sufficiently high temperature to cause the film to become tacky and bond to the insulation.
