A method of making a storage bag comprising the following steps performed in any order: (a) forming a composite tube having an inner surface comprising a higher melting polymer, an outer surface comprising a lower melting polymer, two ends, and a diameter; (b) flattening the tube in a direction perpendicular to the diameter; (c) forming a joint at one of the ends at a temperature between respective melting points of the higher melting polymer and the lower melting polymer; (d) providing a composite sheet having a first side comprising a higher melting polymer and a second side comprising a lower melting polymer; and (e) disposing the composite sheet over the joint such that the first side comprising a lower melting polymer engages the joint and forming a lap seam over the joint at a temperature between respective melting points of the higher melting polymer and the lower melting polymer, and a storage bag made by such method.

According to a method or an apparatus for fastening bristles in a bristle carrier (10) without using an anchor a heating (39) is provided in a tool part configured to transport the bristles. After inserting the bristles into anchoring openings (12) in the bristle carrier (10), the anchoring openings are closed by applying pressure.

A method of directly joining a polymer to a metal along a joint interface through the formation of CO-M chemical bonds, where M represents an element in the metal to be joined. The method includes heating the metal to a predetermined temperature above a glass transition temperature of the polymer and less than a flash ignition temperature of the polymer and less than a metal melting temperature of the metal; physically contacting at least one of the metal and the polymer; and applying compression pressure to the joint interface of the metal and the polymer when the metal is above the glass transition temperature of the polymer and less than the flash ignition temperature of the polymer and less than the metal melting temperature of the metal to generate intimate atomic contact between the metal and the polymer to create CO-M chemical bonds between the metal and the polymer.

A chemical barrier fabric and a method of manufacturing the fabric is provided. The chemical barrier fabric includes at least first and second chemical barrier layers which have an interfacial region therebetween and which are intermittently point bonded providing a point-bonded area which is in the minority and an un-bonded area which is in the majority in the interfacial region. The chemical barrier layers typically comprise single layer polymer films and/or co-extruded layers. A non-woven layer may also be point-bonded to either the first or the second chemical barrier layer to give support to the fabric.

The present disclosure relates to methods and apparatuses configured to bond elastic laminates together between a rotating drum and anvil. The drum includes a fluid nozzle and a press member. As such, a first elastic laminate and a second elastics laminate may be advanced in a machine direction onto the rotating drum. A fluid is heated to a temperature sufficient to partially melt substrate layers of the first and second elastic laminates. As the drum rotates, the press member shifts radially outward from the drum wherein a length, L, of the pattern surface extends in the cross direction across a plurality of elastic strands of first and/or second elastic laminates. And the partially melted portion of the substrate layers of the first and second elastic laminates and the plurality of elastic strands are then bonded together by being compressed between the pattern surface and the anvil roll.

A method for producing a tube skirt for a flexible tube, said tube skirt being manufactured from a flat strip 1 comprising a decorative film 15 superimposed on a primary film 16, said primary film 16 comprising a sealable inner layer 14 at the lower surface 20 of the strip 1 as well as two stabilizing layers 11, 13, said decorative film 15 comprising a sealable outer layer 7 at the upper surface 19 of the strip 1, and a decorative layer 8, 9. This method comprises the following steps: winding the flat strip 1 into the form of a sleeve to shape the tube skirt; superimposing a first side border 2 of the strip 1 on a second side border 2 of the strip 1 to form an overlapping area 3, the sealable inner layer 14 of the primary film 16 of the first side border 2 overlapping the sealable outer layer 7 of the decorative film 15 of the second side border 2; applying a heating temperature T2 to the inside of the tube skirt at the inner face 22 of the overlapping area 3 to produce the side weld of the tube skirt; simultaneously with the application of the heating temperature T2, applying compression between the outer 21 and inner 22 faces of the overlapping area 3 so as to finalize the side weld of the tube skirt.

A method attaches a liquid-repellent filter to an air vent of a resin molded article accommodating a component/electronic part. A thermal processing tip and a thermally welding tip and a molded article are provided. The thermal processing tip (22) forms a filter attachment surface (14) at the inlet or outlet of an air vent (16) in a thermoplastic resin molded article (13). A filter fixing rib (15) is formed around the attachment surface. The porous filter (18) is dropped onto the filter attachment surface, and a thermal welding tip (2) is used to melt the filter fixing rib such that the melted resin flows onto and covers a circumferential edge portion of the filter, penetrating the body of the filter. The melted resin penetrating the filter 18 and covering the circumferential edge portion of the filter are cooled to solid, whereby the filter is fixed to the filter attachment surface.
