Abstract: 1,004,961. Attaching containers to cards; partitions for boxes; dispensing paper cups. MOIRS Ltd. April 30, 1963 [Feb. 11, 1963], No. 17040/63. Headings B8P and B8S. [Also in Divisions B5 and B6] Containers such as paper cups for chocolates are secured in predetermined formation on a backing card coated with adhesive and cut from a web, by rendering the adhesive tacky, depositing a group of the containers on the card and allowing the adhesive to dry. The carded containers may be passed through steam to cause them to open out to facilitate placing chocolates within them. The described apparatus comprises two horizontally reciprocating carriages 20, 25 connected by links 26, 27, rods 30 mounted on the trailing carriage 20 passing through apertures in brackets on the leading carriage 25 and bearing springs 31. Only the carriage 25 is driven and as it advances, it causes jaws 15 on the links 27 to close on jaws 16 on the carriage 20 to grip the web W, or preferably a series of parallel webs in a multi-lane machine and pull them from rolls 10. On the return stroke, the carriage 20 is not moved initially due to clearance between the ends of the springs 31 and the carriages but the links 27 move backwards to release the webs which are prevented from return movement by pawls 33. The springs then engage the carriage 20 to push it back until it engages a stop 24<SP>1</SP>. The stop is adjustable to alter card lengths. The webs are severed by knives 14<SP>1</SP> and the cards 11 fall between dogs 38 on conveyer chains 40, the dogs protruding above a slotted bed having suction apertures to hold the cards. The chains are advanced by pawls 41 on the carriage 25 engaging the dogs. The cards are heated by means, not detailed, to render the adhesive tacky and pass beneath a series of mandrels, Fig. 7a, on a vertically reciprocating head 48. Each mandrel supports a stack of cups C by frictionally engaging the uppermost and comprises a gripper portion 52, spring-biased downwards and mounted for rotary motion when pressed upwards, in a holder 51. The head 48 descends so that the nested cups are pressed against the cards and all but the lowermost rotated by rotation of the portions 52. This releases the lowermost so that they remain adhered to the cards as the head 48 rises. Spring-loaded pins 57 on the head 48 hold down the cards during the initial disengaging movement. A pawl-operated counter (not detailed) stops the machine when enough mandrel strokes to exhaust the stacks have been performed. A stripper plate 66, Fig. 11, is then lowered by a handle 68, Fig. 1, to remove any remaining cups into a tray 67 pushed forward for the purpose and a cup loading board 7 with new stacks C located on it is advanced, pushing clear the tray 67. The head 48 is caused to descend so that the mandrels engage the fresh stacks. The completed cards are urged by a brush 61 on to a smooth conveyer 64 running at right angles to their original direction which advances them to a slower-moving friction surfaced belt 72, Fig. 3, so as to change the intermittent to continuous supply. A shoot 74 reverses the cards for passage over steam outlets 79 in a tunnel 77. Air inlet apertures 84 cause the cards to curl in addition to the opening out of the cups by the steam, this also facilitating filling. The cards are turned upright by a shoot 85, cooled on a belt 86 and fed to the filling position (not described) by a conveyer 73. The machine is pneumatically operated throughout (Fig. 12, not shown). Specification 928,429 is referred to.
