<p>There is described herein an improved sealing film applying machine, of extremely reduced size, and adapted to package, in addition to parcels, also signatures and individual brochures. Said machine is characterized in that it substantially includes a feeding device (2) for the parcel, the leaflet or similar to be packaged, having a pusher member (9) located downstream therefrom, and traversing in a direction at right angles relative to the axis of said feeder device. Said pusher member causes the forward motion of the parcel, or leaflet (3), between a pair of films (11) of a suitable thermally shrinkable plastic material, fed out of an upper and a lower roll respectively, and sealed at the adjacent ends thereof, in order to form together a continuous surface. In practice, said pair of films cover the upper (14) and lower face of the parcel, or of the leaflet, and are subsequently sealed, downstream from the latter, by means of a suitable sealing blade (20). Means are further provided, for a proper positioning of the plastic film in general, and for stopping the parcel or leaflet in a proper position, during packaging thereof.</p> |
