An apparatus for packaging stacks of folded paper products such as handkerchiefs or the like with blanks of plastic film, comprising at least one pocket (58), insertion means (5), along an insertion direction, of a single stack in said pocket (58) with the interposition and consequent folding of a corresponding blank, said pocket (58) being operatively associated with stop means (24) of the stack completely inserted within said pocket. There are control means (22) adapted to operate the stop means (24) in a coordinated manner with respect to the operation of the insertion means (5), to provide an abutment to the stack during the whole insertion step in the pocket (58), the stop means (24) comprising suction means (72) adapted to keep the film in position and to disengage the same film at least in an extraction step of the stack from the pocket.
A unit for compressing and inserting a sequence of stacks of tissue paper products or the like, from an upstream feeding system to a revolving drum for packaging stacks with blanks of plastic film, said unit comprising insertion means for inserting said stacks in said drum in a radial direction and compression means for compressing the stacks, preliminary to said insertion, in a direction substantially tangential of said drum, wherein said compression means and said insertion means are supported respectively by a lower arm and by an upper arm radially projecting from a rotation axis of said drum and arranged sideways to the same drum, said arms being tiltable in a reciprocating manner, independently one from each other and from the drum, around said axis, driving means being provided for driving, respectively, said insertion means, said compression means and said arms, in a coordinated manner with each other and with the rotation of said drum.
