Abstract: A container labelling method consisting of predisposing means (3) for supporting at least one container (2) in an erect position; from below, mounting onto the body of said at least one container a heat-shrinkable label in the form of an annular band; and causing the (5) label to adhere to said container. The method is implemented by a plant (1) comprising a device for supporting and transporting (3) at least one container which acts from above on the container suspended in an erect position; means for mounting a heat-shrinkable annular band (4) onto the container from below; and means for causing said label to adhere to said container (6) by heat-shrinkage.

Abstract: A method comprises forming a preform of plastic material, expanding said preform to obtain a container, said forming comprising compression-forming said preform in that mould arrangement wherein said expanding occurs; a method comprises expanding a preform in a mould arrangement to obtain a container, before said expanding it being provided to form a dose of plastic material in a paste state in said mould arrangement to obtain said preform; an apparatus comprises a forming mould arrangement, a punch device for expanding a preform in said mould arrangement, an abutting device cooperating with said punch device, said punch device and said abutting device identifying a configuration in which said punch device and said abutting device cooperate to define a forming unit for compression-forming a semifinished product of plastic material to obtain said preform and a further configuration in which said punch device and said abutting device cooperate to define an expansion unit of said preform to obtain a container.
