ABSTRACT:
A rotating turrent equipped with a plurality of spring-biased, reciprocating vacuum nozzles is employed in conjunction with a packaging machine which forms packages from strip stock. The reciprocating nozzles are rotated about a stationary cam which sequentially thrusts the nozzles out into engagement with the outer sidewall of a strip of U-shaped stock material which has been formed into a series of longitudinally-spaced pockets and which strip is positively secured to a filling station at its other sidewall by suction means. The spring-biased vacuum nozzle is then retracted in order to effect separation of the top edges of the sidewalls and permit filling of the pocket with a granular material.
