1,171,974. Manufacture of article carriers. DIAMOND INTERNATIONAL CORP. 19 Jan., 1967 [25 Jan., 1966], No. 2928/67. Heading A4. In a method and machine for carrying out the method for assembling a paperboard bottle or can carrier with its plastics handle section, a rotating cam 115, Fig. 3 and linkage 121 raises suction cups 111, Figs. 2B, 3 to remove the lowest blank 100 from a stack at 101 and draw it downwards between carrying guide plates 102 which fold the carrier side walls upwardly. At the same time spring loaded fingers 112 carried by the suction assembly are raised via a linkage 124 to pass through holes in the blank and raise carrier end flans 104. An eccentric and linkage 216, 214, 213 act on slide bars 211 having hinge members which engage the carrier edge and shift it laterally so that the top side wall edges enter a guide which bends the edges inwards to form locking tabs 105, Fig. 2E. Hinge bars 211 then shift the carrier to a third position where the lowermost handlesection 300 in a stack is removed by reciprocating fingers and caught by a gripper which lowers it on to supports 321, Fig. 11 within the divergent side walls of the carrier which lie against spring-loaded hinged hooked plates 310. The eccentric then pulls down cam plates 345 which, via rollers 346, move plates 310 and the carrier side walls inwards and then, via stops 344; and plate extensions 343 lower the plates so that the hooks engage the locking tabs 105 with the handle section. Equally the handle section can be moved upwards to engage the tabs. A finger 341, Figs. 3, 11, on endless chain 340 then engages and ejects the assembled carrier. |
