Abstract: The method of manufacturing shoes of the present invention comprises a pre-step of heating a following reactive hot-melt adhesive to melt it and providing the melted adhesive on a joining surface of at least one adherend, an ultraviolet treating step of irradiating the adhesive with ultraviolet light having irradiation energy more than 100 mJ/cm2 and less than 1200 mJ/cm2 to polymerize a polyurethane prepolymer, and a joining step of overlaying a joining surface of another adherend on the adhesive to bond both adherends together. The reactive hot-melt adhesive contains a polyurethane prepolymer having an (meth)acryloyl group and an isocyanate group at the end of a molecule, and a photopolymerization initiator. The polyurethane prepolymer includes a non-crystalline polyol and a crystalline polyol, wherein the non-crystalline polyol is contained from 20% by mass to 90% by mass with respect to the whole polyols. The viscosity of the reactive hot-melt adhesive at 80° C. is 300 Pa·s or less.

Abstract: A laminate for laser bonding of the present invention contains a bonding sheet that is melted by irradiation of laser light and a first member laminated on one surface of the bonding sheet and formed of a thermoplastic foam. The difference between the melting point of the first member (Mfoam) and the melting point of the bonding sheet (Msheet) (Mfoam?Msheet) is ?50° C. to 20° C. and the difference between the melt viscosity of the first member (Vfoam) and the melt viscosity of the bonding sheet (Vsheet) (Vfoam?Vsheet) is 3.0×105 Pa·s to 8.0×105 Pa·s. Preferably, the laminate for laser bonding contains a second member having transparency to laser light laminated on the other surface of the bonding sheet.

Abstract: Electro-unite tubes having different plate thicknesses or different diameters are breakdown-formed without changing the upper rolls and the lower rolls of the breakdown pass rolls each time. Each of breakdown pass rolls 12 includes an upper roll 12a having a convex curved surface and a lower roll 12b opposed to the upper roll 12a, the lower roll 12b being provided with a V-shaped concave portion 13. A gap is maintained between a metal band plate 11 and the deepest portion D in the concave portion 13, and the metal band plate 11 is in local contact with the lower roll 12b. The upper roll 12a can be moved up and down, and the distance between the end of the curved surface of the upper roll 12a and the deepest portion D in the concave portion 13 is adjusted depending upon the plate thickness and the diameter of the electro-unite tube to determine the curvature (R.sub.1 or R.sub.2) for forming the metal band plate 11.
