Abstract: A protective barrier for protecting a pipe extending through an opening in a framing member.

Abstract: An apparatus for continuous bakery products includes a carriage having opposed sealing jaws. Upper and lower webs of wrapping material extend between the jaws of the carriage along a bakery product path. Bakery products to be wrapped are advanced along the bakery product path between the webs of wrapping material and between the initially open jaws of the carriage. The jaws of the carriage are then closed to form transverse seals at the trailing edge of a leading package of bakery products and at the leading edge of a trailing package of bakery products. The carriage is advanced along the bakery product path during the sealing operation so that sealing of the bakery product packages is carried out on a continuous basis.

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: An oscillating sealing wire for high speed sealing of thermoplastic film. The sealing wire curved in the shape of a bow rocks back and forth across the moving surface of a thermoplastic film so the wire continuously presents a hot surface to the film. The film removes heat from the wire surface which touches the film. The oscillating wire continuously presents a new hot surface to the film to allow high speed movement of the film and still obtain a good seal.
