| 摘要 | 1,156,862. Boots &c. BRITISH UNITED SHOE MACHINERY CO. Ltd. 19 Aug., 1966 [20 Aug., 1965], No. 37146/66. Heading A3B. A method of assembling a shoe upper includes the steps of laying the parts of the upper on an adhesive coated carrier web with adhesive between the overlapping parts of the upper, pressing the parts together while the adhesive is active and then separating the assembly from the web by cutting along the periphery of the upper. As described a web 10 of lining material is advanced intermittently from a supply 12, e.g. an extruder or a supply roll, and passes through a marking station 24 where the outline A of the upper and each of the components is printed on the web 10. The web then passes through an adhesive applying station 30 which coats the area B within the outline of the upper with adhesive. Succeeding stations 32, 34 and 36 sequentially apply a counter C, box toe D and throat stay E, each of these consisting of a layer of thermoplastic material printed on to the upper in the appropriate region. The web 10 then passes through a heating tunnel 38 to activate the adhesive and operators then place the components I to VI of the upper in position on the web with their edges overlapping, the margins of the upper components. having previously been coated with adhesive. The web then passes through a press 50 to bond the parts together, the adhesive being activated by a high frequency electric field. Finally the assembled upper passes through a cutting station 60 where the completed upper, including a lining 70, is cut from the web 10 and the remainder of the web 10 is wound about a take up roll 16. | ||||||
