ABSTRACT:
In a wrapping apparatus, particularly for enclosing articles consisting of or containing groups of cigarettes in wrapper material, the articles are received in a pocketed drum in which at least one overlapped region of the wrapper material is heat scaled. Preferably opposed side seams and an end flap of the wrapper are sealed, so as substantially to complete the enclosure of the article while on the drum. Side seal heaters carried by the drum may be mounted on respective annular carriers which are rotatably displaceable to remove the heaters from contact with the articles if the drum is stopped for an extended period. End seal heaters may be pivotally mounted on the drum and operated by a cam arrangement to fold an end flap of the wrapper into an overlapped position.
