Abstract: There is disclosed herein an attachment for a laminating machine. The attachment permits one-sided lamination by adjustably imparting a reverse curling force to an initially curled laminate. The reverse curling force is imparted by bending and/or stretching the heated and laminated product before the film sets so as to offset the initial curl. This is done by drawing the laminated product over a bar edge and adjusting the draw with an adjustable roller.

Abstract: An apparatus for pressing laminated composites formed of two glass layers and one interposed thin plastic layer presses the glass/plastic composite while the glass/plastic composite is in a vertical position. A horizontal conveyor delivers the composite to the apparatus, and a tipping device places the composite in a vertical position. A suction cup unit, which is rotatably mounted on a supporting shaft, receives the composite from the tipping device. A movable carriage moves the supporting shaft, suction cup unit, and composite to a pair of pressing rolls. The pressing rolls receive the composite therebetween and press the composite layers together. Another rotatably mounted suction cup unit removes the composite from the pressing rolls and delivers the composite to another conveyer. The arrangement allows highly curved glass/plastic composites to be pressed with no risk of breaking the glass and without requiring manual intervention.

Abstract: A method of and apparatus for dynamically mechanically bonding together a plurality of laminae, at least one of which comprises thermoplastic material: for example, polyethylene. In one aspect of the invention the laminae are forwarded in face to face relation through a pressure biased nip between a patterned nip defining member and an opposing nip defining member (e.g., a relief patterned cylinder and an anvil cylinder) which members are independently driven to maintain a predetermined surface velocity differential between them. In another aspect of the invention which is particularly useful at intermediate and higher line velocities--preferably for line velocities of about 300 feet or more per minute and, more preferably, for line speeds of about 450 feet or more per minute--the nip defining members may be operated with equal surface velocities.

Abstract: A rotary film sealing and severing device for use with thermoplastic film for forming packages. The device includes a rotating anvil assembly and a counter-rotating film cutting assembly having a heated sealing and cutting knife. First and second liquid cooled clamping bars on either side of the knife hold the layers of film together while the film is being sealed and cut. Cooling the clamping bars prevents the film from adhering to the clamps and causes the layers of film to quickly fuse together and allows high speed operation by preventing separation of layers of film due to slow cooling.

Abstract: A process and apparatus for bonding and embossing of sheet material is disclosed. The apparatus uses a pair of rotating calender rollers which are spaced apart. Sheet material is introduced into the space between the rollers. The calender rollers are equipped with raised, discrete points which form a surface design and determine the embossing design produced on the sheet material. The calender rollers are each driven at a synchronous speed by a drive system having the capability of varying the speed of one roller for a short period of time. This change in speed causes the surface designs of both calender rollers to shift relative to one another. This results in different degrees of overlap between opposing pairs of raised points. Thus, different embossing surface patterns can be produced as the overlapping areas are adjusted while the machines are in operation. This eliminates the necessity of replacing the calender rollers when a change of embossing patterns is desired.
