ABSTRACT:
The machine is designed to enfold substantially parallelepiped packs in single transparent wrappers and comprises an indexing wheel provided with radial pockets each designed to accommodate one pack together with its wrapper, which is folded to the point where the pack becomes entirely enveloped save for an area of each end face lying at right angles to the axis of the wheel; the wheel includes a pneumatic clamping system whereby suction is applied during the indexed rotation both to the uncovered areas of the pack and to other parts enveloped by the wrapper, in order to disallow movement of the pack internally of the pocket and prevent any relative movement between pack and wrapper.
