[Also in Division A3] A method of making a shoe includes the step of using an adhesive which does not require heat for activation e.g. a pressure-sensitive adhesive, to effect the top line seam and at least some of the seaming of the outer and/or lining of the upper. As described a shoe upper 1 is formed from two blanks 1A and 1B joined to-. gether along a side seam 2 and a preferably straight back seam 10. The seams 2 and 10 are formed by lap joints using a cold setting adhesive, the edges of the blanks being skived so that the joint is of uniform thickness, and the joints may be reinforced by stitching. The lining 12 is formed in a similar manner with its side seam on the opposite side to the seam 2 and is bonded to the outer 1 by adhesive 15 (Fig. 4). The top edge of the upper blank is skived as shown in Fig. 2 and is folded back on itself as shown in Fig. 4. A reinforcing tape 11 is bonded in the fold by a cold-setting adhesive and the lining 12 is bonded to the rebate skive 6 by an adhesive 14. |
