摘要:
Methods include providing a plurality fabric material layers, applying a plastisol layer between each fabric material layer forming plurality fabric material layers thereby creating a belt carcass, pressing the fabric material layers together with the plastisol layer(s) at a pressure of at least 5 psi to produce a preformed fabric carcass while heating the preformed fabric carcass while heating the preformed fabric carcass to a temperature which is within the range of about 360° F. to about 450° F. for a period of at least 6 minutes, disposing a thermoplastic elastomer polyvinyl chloride alloy composition onto the upper and lower surfaces of the fabric carcass, pressing the thermoplastic elastomer polyvinyl chloride alloy composition onto the upper and lower surfaces of the fabric carcass, and splicing opposing distal ends of the belt in a stepped splice configuration. The layers may be devoid of covering strips of lattice fabric disposed adjacent an abutment of any proximally positioned fabric layer.

A composite structure comprises stacked sets of laminated fiber reinforced resin plies and metal sheets. Edges of the resin plies and metal sheets are interleaved to form a composite-to-metal joint connecting the resin plies with the metal sheets.

An endless handrail manufacturing method includes: a first step of cutting the dorsal part on one end side and the dorsal part on the other end side of a belt-like molded product to expose a tension member from the end portions; a second step of heating the product on the one end side, then removing the softened resin member, and then exposing a canvas from the end portion; a third step of heating the product with a heating jig to dent the abdominal part; a fourth step of applying an adhesive to the terminal on the one end side or the terminal on the other end side of the product, then fitting the former terminal to the latter terminal of the product; and a fifth step of supplementing a resin to the fitting portion, then hot pressing the fitting portion to fusion-bond the terminals.

A system for welding two parts to be joined made of thermoplastic synthetic materials along a weld seam by a laser operating with a laser beam having a beam direction within an operating field by a control method with control data corresponding to the weld-seam course to be produced, including a beam dimension in the region around its focus causing the welding, which is smaller in the joint plane than the target width of the weld seam to be produced, and is dependent upon the angle of incidence of the laser beam on the joint plane and/or upon the position of the focus relative to the joint plane, is displaced in a first movement component in a principal forward-feed direction along the track of the weld-seam to be produced, in a second, oscillating movement component superimposed over the former to cover the weld-seam width transversely to the principal forward-feed direction with an oscillation amplitude value, and is adjusted with a control method in its oscillation amplitude width in inverse dependence upon the beam dimension in the joint plane such that the width of the beam field covered by the laser beam in the transverse direction relative to the principal forward-feed direction corresponds to the target width of the weld seam.

A method for manufacturing a pneumatic tire may include lap-splicing end parts of a laminate sheet in which a sheet obtained from a thermoplastic resin or a thermoplastic resin composition of a thermoplastic resin blended with an elastomer is laminated with a rubber that undergoes vulcanizing adhesion with the thermoplastic resin or the thermoplastic resin composition. After the sheet obtained from the thermoplastic resin or the thermoplastic resin composition is cut into lengths to be supplied for lap-splicing, and at a stage before tire vulcanization molding, distal end parts of the sheet obtained from the thermoplastic resin or the thermoplastic resin composition are sharpened with a thermal treatment.

An airfoil includes at least one precured composite spar having a web and at least one flange integrated with an end of the web. A precured composite skin is attached to the spar by adhesive bonding the skin to the flange.
摘要:
A method of manufacturing a pneumatic tire having high durability, in which when a tire is manufactured, including: cutting at a predetermined length a laminated sheet obtained by laminating a sheet of a thermoplastic resin composition obtained by blending a thermoplastic resin and an elastomer, and rubber to be cured and adhered to the thermoplastic resin composition; lap splicing end portions of the laminated sheet; and cure-molding the laminated sheet, such that delamination does not occur between the sheet of the thermoplastic resin composition and the tie rubber sheet cured and adhered to the sheet of the thermoplastic resin composition, which collectively constitute the inner liner layer. In this method cure-molding the laminated sheet can form an inner liner layer, and the cutting can be effected by thermal cutting at a temperature equal to or higher than a melting point of the thermoplastic resin.

The invention relates to an electronic button tag for tagging and identifying cattle and other animals, of the type which is intended to be placed on one of the ears of the animal. The inventive button tag includes a transponder which is enclosed in a shell. The shell is made from two half-shells, namely a lower half-shell and an upper half-shell, which are assembled together at a median plane. The transponder is fixed in place, without compression. between the two half-shells using a glue; and the two half-shells are assembled by a laser weld.
