摘要:
A system and method of making an open-ended, reinforced, layered belt having a profile layer, a top layer material, and tensile cords fully encapsulated there between. The method includes engaging portion of the profile layer on a rotatable cylindrical mandrel with an engaging roller, disengaging with a take-off roller, and applying and fusing the cords to the profile layer at a desired cord spacing there between. The cord may be fused by melting the profile layer surface with a heated plow and/or with heated cord. The cord is then covered with the top layer material in a lamination step involving heating to melt at least a portion of the top layer and pressing it to fuse it to the reinforced profile layer. Lamination may be done downstream or directly on the mandrel.

A method for folding a fastener during a high speed manufacturing process and maintaining the fastener in a folded configuration throughout the high speed manufacturing process. The method includes obtaining an article that has a foldable fastener and moving the article in the machine direction during the high speed manufacturing process. The foldable fastener has first and second opposing surfaces, a web and at least one engaging member joined to the web. The method includes applying a frangible bonding agent to a first portion of the first surface of the fastening system; folding the fastening system such that the frangible bonding agent contacts a second portion of the first surface of the fastening system; and allowing the frangible bonding agent to cool at a temperature of less than 60° C.

A process for preparation of a tufted polyamide-type fiber carpet is provided. A primary backing tufted with yarn comprised of at least 85% by weight of fibers selected from the group nylon fibers, wool fibers, and blends thereof is provided. A molten polymer adhesive is provided on the back side of the tufted primary backing, the polymer adhesive consisting of at least 85% by weight of one or more ethylene copolymers each comprised of 50 to 95 weight % of ethylene, and 5-50 weight % of at least one comonomer selected from the group of esters and carboxylic acids. The tufted primary backing and the molten polymer adhesive layer are compressed under a moving belt that applies a pressure of at least 1 N/cm2 for a period of at least 5 seconds during which time the polymer adhesive remains in a molten state. The molten polymer adhesive then cooled to a temperature below the melting point of said molten adhesive. A secondary backing may be placed over the molten polymer adhesive on the back of the primary backing.

摘要:
A method is provided for producing a thermoplastic resin sheet or film by hot-melting and then cooling a thermoplastic resin to form a sheet or film. The thermoplastic resin sheet or film is moved so that it is pressed against the outer surface of an external heated roll and against a heated, endless metal belt. The endless metal belt is disposed at one end around a moving, internal heating roll and at an opposite end thereof around a moving, internal cooling roll. The internal heating roll heats the endless metal belt to a temperature higher than the softening point of the thermoplastic resin and higher than the temperature of the external heating roll to thermally adhere the thermoplastic resin sheet or film to the external heated roll or the heated, endless metal belt. The thermoplastic resin sheet or film is then moved along on the external heated roll or belt into a high temperature zone. The thermoplastic resin sheet or film is then released from the contact with the external heated roll and released from contact with the endless metal belt in a low temperature zone. The thermoplastic resin sheet or film is then peeled from the endless metal belt. Methods are also provided for producing a laminate of two or more thermoplastic resin sheets or films. The above methods provide non-stretched thermoplastic resin sheets, films or laminates with high-quality surfaces, which are suitable for wrapping foods and medicines.
