<p>An arrangement, apparatus, and method for alternately stacking material, such as copper, glass, etc. to form a stack of uncured laminates in a laminating press line. A material sheet pick-up and depositing head has at least one compartment which receives negative air pressure for a pick-up mode, and positive air pressure for a material sheet depositing mode. A slightly curved convexed surface on the underside of this head may cooperate with the positive pressure in first forcing the center of the sheet downwardly and then outwardly onto the build-up station, whereby air is dispelled from between the sheet and the already uncured stacked laminates, resulting in the sheet being placed smoothly onto the stacked laminates. A conveyor belt system mounted on the head cooperates with the negative air pressure to uncoil a sheet of material from a let-off unit.</p> |
