Abstract: 1,108,931. Making uppers. DUNLOP RUBBER CO. Ltd. 3 Nov., 1964 [12 Nov., 1963], No. 44544/63. Heading A3B. [Also in Division B8] A machine for winding cotton cord 51 on to a core member 30 to form an article such as a shoe upper thereon, is so constructed that the core 30 can be supported on a bracket 16 movable so that it is first traversed in one direction relative to a cord applying means 34a to cause the cord to be laid along one side of the core, followed by rotary motion of the bracket 16 causing the cord to be applied around one end of the core, followed by traverse motion in the opposite direction causing the cord to be laid along the opposite side of the core, followed by a further rotary motion causing the cord to be applied around the other end of the core, and so on, the cord applying means 34a being movable away from the plane, of traverse androtation of the bracket so that the cord turns may be laid in side-by-side relationship, and displaced as and when necessary to follow the contours of the core. In the particular embodiment the core 30 is in the form of a shoe upper and has a metal base that can be gripped by a magnetic head on the bracket 16. In operation a stockinette is first pulled over the core 30, and its metal base, before the core is placed on the magnetic head. The parts of the stockinette covering the side and top of the core are then covered in adhesive and the cord end is brought into contact with the feather portion of the heel of the core and adhered thereto by adhesive. A motor 24 drives a cam 18 causing the bracket 16 to traverse along the guide means 6. Gear wheels 26, 27 (26 is not visible in Fig. 1) having missing toothed portions are used to rotate the guide means 6 in an intermittent manner so that rotary motion thereof takes place as and when required. By manually turning a handle 42 the stylus 34 can be rotated about an axis 46. By turning a further handle 49 the stylus 34 can be displaced radially with respect to the axis 46. In this manner the stylus tip 34a, that is biased against the core 30, can be moved in any direction relative to the core 30 so that the core is covered to the desired extent and desired manner with adjacent turns of the cord. Zig-zag or sinuous windings. By using separate electric motors to drive the cam 18 and rotate the guide means 6, as well as separate electric motors for causing rotary and radial movement of the stylus 34 with respect to the axis 46, all of the motors being programmed upon a master control device receiving signals initiated by a punched card device, the cord can be caused to be wound around the core in a zig-zag or sinuous manner. Hot air jet acting on thermoplastic base. The stockinette may be impregnated with a thermoplastic material having a polymeric base and the stylus 34 may move with a heated tube through which air is passed to soften the thermoplastic material at the point where the cord is being applied. Fully automatic arrangement. The Specification describes (Figs. 11 to 17, not shown) an embodiment in which the application of the cord 51 to the core 30 is fully automatic, the means for moving the bracket 16 along the guide means 6 and the means for rotating the guide means 6 being of different design from those in Fig. 1.
