Abstract: 1466268 Adhesive nozzles BRITISH UNITED SHOE MACHINERY CO Ltd 11 April 1974 [13 April 1973 16 Aug 1973] 17813/73 and 38790/73 Heading B2L [Also in Division A3] A shoe upper conforming machine for simultaneously lasting opposite side portions of shoes in at east the waist region thereof, has nozzles 270 to operate at opposite side portions of a shoe assembly and longitudinally movable relative to the shoe assembly, means are provded for initially moving the nozzles into proximity with a mid portion of an insole and for then moving the nozzles outwardly toward opposite sides of the insole to predetermined position determined by template means whereby, on relative movement between shoe supporting means 2 and the nozzles in a direction extending lengthwise of the shoe assembly, the nozzles may be displaced, in directions extending widthwise of the shoe assembly in a desired manner to extrude adhesive between the marginal portions of the upper and insole. Shoe support means 2 positions the shoe assembly so it can be worked upon by lasting rolls 4. Carriage 20 mounts the shoe support means and the heel band assembly 30 and provides the relative movement between the rolls and the shoe assembly by being movable by piston 80 in channel members 26. When the carriage is moved to the left post 10 is lent forward for reception of a shoe assembly, the post is then moved vertical and then upwardly by piston cylinders 42, 36 respectively. The pad 72 is movable by piston 74. A two armed lever 52, 54 pivoted by piston cylinder 62 moves the engaging plate 68 into engagement with the toe end of the shoe to effect measurement of the length of the shoe assembly. The carriage is then moved to the right so that the shoe assembly is correctly positioned relative to nozzles 270, this is determined by stop screw 14. Traversing of the shoe assembly post rolls 4 and nozzles 270 is controlled by an adjustable hydraulic dash pot arrangement 320.  Nozzles 270 are carried on nozzle bodies 272 and can be moved vertically or horizontally by cylinders 293 and 307 respectively. A foot 312 is associated with each nozzle 270 so that the nozzle follows the contour of the insole. Springs 290 counterbalance the weight of the bodies 272. The nozzles have a needle valve therein to stop drooling between cycles. Each template 348 is contacted by a follower 346 attached by cable 330 to the respective nozzle. The templates are inversely proportional to the shoe assembly and are movable to cater for variations of shoe width with size. When a shoe asembly is gripped by the heel band the toe portion is displaced somewhat to one one side or the other dependent on if it is for a right or left foot. This displacement allows the machine to sense the foot involved to move the correct mask 36 to allow the correct template 348 to be engaged by its follower 346. The mask is effectively a straight sided template. In a modification for shoes shaped on both sides two templates are provided on each side of the machine. Selection of the correct template can be automatic and similar to the method used above or, an operator may manually select which templates are to be operative.
