ABSTRACT:
A mechanism for engaging a resting bobbin 10 carrying a web of packaging material and raising it into a rotatable web withdrawal position. A pair of bent yoke arms 17,18 straddling the bobbin carry lateral clamping jaws 14,15 at their one ends. Their other ends are movably pivotally mounted to a plate 11 by a pair of support plates 29,30 and a pair of lifting plates 25,26, the latter being eccentrically coupled to meshing drive gears 20,21. The continuous rotation of the gears successively pivots the jaw ends of the yoke arms inwardly to engage the bobbin, and thereafter raises the arms and bobbin into the working position.
