  • Publication number: 20130255869
    Abstract: An integrated process for making an inflatable laminated article comprises extruding a first film and a second film, followed by cooling the first film and the second film so that the films will not fuse to one another upon contact with each other. The films are then brought into contact with one another, and selected portions of one or both films are heated so that the films are heat sealed to one another in a selected area having a desired pattern. The unsealed area between the film provides inflatable chambers between the first film and the second film. An alternative process utilizes a film tubing in lay-flat configuration to produce a laminated inflatable article.

  • Publication number: 20130228278
    Abstract: An inflatable laminated article is prepared by contacting a first film with a second film, and heating selected portions of at least one the first and second films to a temperature above a fusion temperature of the first and second films, so that the first and second films are heat sealed to one another. The heat sealing is carried out in a pattern which provides a plurality of inflatable chambers between the first film and the second film. The first and second films are forwarded at a speed of at least 120 feet per minute while coming into contact with one another. The heating is carried out by contacting the first film with a heated raised surface roller having a release coating thereon.

  • Patent number: 8501061
    Abstract: A method for making a foam-in-place cushion in which a foam-forming composition is dispensed between two plastic film portions in a predetermined fashion to selectively control the distribution of the foam in the cushion. A foam dispenser can be moved in a transverse direction as foam is dispensed. A dispersion device can be employed to apply pressure on predetermined areas of the film portions towards each other so as to cause the composition to be redistributed in position in a predetermined manner while the composition is in a less than fully expanded state. The plastic film can then be sealed closed to form an expanding foam cushion that can be placed into a shipping carton where the cushion expands to fill void space, or into a mold where the cushion expands and is molded into a desired shape.

  • Patent number: 8484922
    Abstract: The invention is directed to a composite foam material that is alkaline and heat resistance. The composite foam material comprises a foam layer that having a film layer attached thereto and in which at least one of the film or foam layers includes a carbon free radical scavenger agent that is dispersed therein. The carbon free radical scavengers neutralize free radicals that are generated in the polymeric material (e.g., film or foam layer) and help prevent the degradation of the foam composite material. In particular, foam composite materials in accordance with the present invention can be used in underlayment applications in which exposure to heat can degrade the underlayment. As a result, the durability and useful life of the composite sheet material can be extended. In some embodiments of the present invention provides a floor underlayment material that overcomes many of the problems discussed above.

  • Publication number: 20130139665
    Abstract: An improved slicer having a reciprocating blade is disclosed. The use of a reciprocating blade allows the configuration and functionality of the slicer to be modified to address many of the deficiencies of current rotary slicers. The slicer operates without manual intervention, and includes the capability to automatically stack the sliced products. In other words, the food product to be sliced is placed on the slicer, and the slicer automatically slices the food product and stacks the sliced product, in a configuration that is presentable to the customer. In some embodiments, the machine is designed to have certain zones that can be cleaned or replaced, while the rest of the machine is never contaminated. In addition, the reciprocating blade is inexpensive and easily replaceable, thereby eliminating the need to sharpen the blade.
