ABSTRACT:
The machine is designed to enfold substantially parallelepiped packs in 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 completely enveloped save for an area of each end face perpendicular to the axis of the wheel. The pockets are enclosed laterally by corresponding pairs of tongues lying normal to the axis of rotation, and indexed through a station to which one longitudinal flank of the part-enveloped pack is engaged by a heat-seal device; the ends of the tongues farthest from the wheel axis carry reaction pads that operate in conjunction with the heated plate of the device, of which the length is substantially equal to the full width of the wrapper, both measured parallel with the axis of rotation of the wheel.
