Abstract: 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.

Abstract: A continuous web in the form of a hose-like thermoplastic foil is intermittently fed through a welding and severing station in which two transverse weld seams on the foil are made and simultaneously a cutting blade severs a completed bag along a line between the weld seams. A transfer unit arranged immediately below the welding station temporarily seizes the severed bag, displaces the same a small distance in feeding direction, and then dashes the rear portion with the still plastic weld seam against an alignment line of a stacking station. The stacking station is arranged a small distance below the welding station at the other side of the severed bag, and the still plastic weld seam fuses with the corresponding weld seam of the preceding bag interlocked in the stack. The completed stack is discharged in a perforating station where the tearing line is perforated simultaneously through all stacked bags. If desired, additional holes are punched between the upper edge of the bag and the perforation line.

Abstract: A set of sheets delivered seriatim from a copier/duplicator or other source are advanced along a sheet path leading from an input station to an assembly station where a booklet is formed. As a sheet is moved along the path a line of adhesive is applied to one surface of the sheet adjacent to one side edge of the sheet. In the assembly station the sheets are jogged to align the sheets of the set and then pressure is applied to the sheets over the line of adhesive. When the entire set has been bound together into a booklet, the booklet is removed from the assembly station and delivered to an output station, such as a tote tray.

Abstract: Assembly apparatus including a vacuum mold for supporting a flexible sheet of interlayer material for assembly against a bent glass sheet or between a pair of bent glass sheets of matching configuration has a first apertured wall shaped to conform to the shape of the bent glass, and a second apertured wall of conforming shape adapted for coupling to a vacuum source to form and hold the flexible sheet of interlayer material against the mold in unwrinkled condition. The mold is pivoted to a carriage from a mold loading orientation of convex elevational configuration to a mold unloading orientation of concave elevational configuration. Carriage movement between a mold loading station and an assembly station is correlated to the elevational configuration of the mold in assembling said flexible sheet of interlayer material against one or more bent glass sheets.

Abstract: This invention relates to an arrangement of vacuum cups in a bent glass sheet sandwich assembly apparatus and a method of using said arrangement that provides a temporary bias to the central portion of a bent glass sheet to insure that a flexible sheet of interlayer material applied to the bent glass sheet initially engages its central portion and the area of engagement extends gradually to the edge of the sheets to avoid entrapment of air or other vapors in the interface of the resulting subassembly. When another bent glass sheet is applied to the opposite surface of the flexible sheet of interlayer material, the subassembly is temporarily biased once more to insure initial engagement in the central portion gradually extending to the edge of the sheets to avoid entrapment of air or other vapors in the interface of the subassembly with the second bent glass sheet.

Abstract: An adhesive applicator has a nozzle through which adhesive can be dispensed to sheets of a set as the sheets are driven seriatim past the nozzle. Adhesive is furnished in a cartridge which is pressurized so that the adhesive is delivered from the cartridge to the nozzle under pressure. A valve controls the flow of adhesive from the nozzle, and the valve is under control of a logic and control unit. The logic and control unit receives signals from various sensors or detectors indicating, inter alia, the presence of an adhesive cartridge, the level of adhesive in the cartridge, the flow of adhesive from the nozzle, and the amount of adhesive in a collection bottle which receives surplus adhesive dispensed from the nozzle but not applied onto a sheet. The logic and control unit is capable of operating the valve that controls flow of adhesive from the nozzle so that adhesive is selectively dispensed from the nozzle to all but one sheet of a set of sheets.
