摘要:
A fabric for the forming, press and dryer sections of a paper machine, for use as a reinforcing base for a polymeric-resin-coated paper-processing belt or as a corrugator belt, or in other industrial settings where a material is being dewatered, is formed from a monofilament yarn (16), which is spirally wound in the form of a closed helix (26), adjacent turns thereof being abutted against and joined securely to one another. The monofilament yarn has a first side and a second side which are oppositely and correspondingly shaped, so that, when spirally wound in a plurality of turns, the first side fits closely into or against the second side of an adjacent and abutting turn, and adjacent spiral turns are secured to one another at the abutting first and second sides to form the fabric.

A method for joining two or more substrates with a seam is provided. The seam is formed with a thermoplastic tape that is capable of forming an adhesive bond and a physical bond with a substrate. For instance, in one embodiment, the thermoplastic tape is formed from a polyurethane film. In addition, the seam can be utilized in a flat configuration or folded into a variety of different shapes, such as in a z-shaped configuration. As a result of the present invention, it has been discovered that a seam can be formed to have improved strength without substantially sacrificing the desired functional properties of the substrate materials.
摘要:
A joint construction in a laminate of, alternately, at least two metal layers (1-3) and at least one plastic layer (6,7) accomodated between them comprises metal layers which have at least two sections (4',5',-4''',5'''). The two sections of at least one outer metal layer (4',5') overlap one another and are fixed to one another at the location of the overlap (8) by means of an adhesive (12). Each metal layer (1-3) has overlapping sections (8-10) which are fixed to one another by an adhesive (12).
摘要:
A metal member (31) suitable for use in friction stir welding, having a first face sheet (33) extending in length and width directions of the member (31) and having an outer face facing outwardly in the thickness direction of the member, and at least one cross-web (35,36) extending in the thickness direction at an angle to said face sheet wherein at at least a first lateral edge of said face sheet there is a rebate formation extending along said first lateral edge and defined by a first surface facing laterally and a second surface facing outwardly in the thickness direction and, adjacent said rebate formation, a weld sink compensation rib (37a) extending along said first lateral edge and standing up from said outer face.
摘要:
A seamed flexible belt (30) with interlocking seam members (64,65) having an outer layer (66) including a polyvinylbutyral and an isocyanate, or a polyurethane from the reaction of polyvinylbutyral and an isocyanate, for use in the xerographic, contact electrostatic, digital and other like machines.
摘要:
A joining structure is provided which includes a first resin member (1) and a second resin member (2) having respective joining portions that are joined together by friction welding. The joining structure further includes a projecting wall (5) that is opposed to the joining portions of the first and second resin members with a spacing therebetween. In the joining structure, at least one notch (15) is formed in a surface of the projecting wall (12) that faces the joining portions of the first and second resin members.

摘要:
A frictionally welded, filled thermoplastic article is strengthened by restricting lateral flow of molten material out of the gap between the workpieces, so that a molten pool of substantial depth is maintained from the beginning of melting to the onset of solidification. The restriction to lateral flow of material is provided by dams (projections) of essentially rectangular cross-section at each lateral edge of one of the workpieces, while the other workpiece has a substantially flat mating surface.
