Abstract
A packing machine, wherein an indexible turret carries an annulus of hollow mandrels for arrays of cigarettes, has a tongs which delivers a flat blank between two neighboring mandrels during each period of dwell of the turret, and such blank is placed against the front side of the mandrel therebehind, as considered in the direction of movement of the turret. A biasing member is installed between each pair of neighboring mandrels, and the biasing member which is adjacent to a mandrel that is contacted by a freshly supplied blank is thereupon moved against the outer side of the blank to urge it against the front side of the mandrel. The blank is then converted into a U-shaped body overlaying the front side and the lateral surfaces of the respective mandrel while it is held by the adjacent biasing member. The marginal portions of the U-shaped body are thereupon folded over each other at the rear side of the respective mandrel and adhere to each other under the action of adhesive which is applied to the outer marginal portion. The respective biasing member is then shifted forwardly to bear against the outer marginal portion of the blank surrounding the preceding mandrel to prevent separation of the marginal portions before the adhesive sets. The biasing members are moved rearwardly by discrete springs and forwardly by a stationary cam. Electromagnets are provided to hold the biasing members in neutral positions during introduction of fresh blanks between the respective mandrels.
