Abstract: A facility for heat-shrinking sleeves made of heat-shrinkable material inserted onto supports, such as containers, includes an enclosure provided with a heat-diffusion means, a conveyor for carrying the supports through the enclosure between an intake of the enclosure and an output of the enclosure, the enclosure including a base and a hood which is mounted mobile between an open position allowing access to the conveyor and an operational position in which said hood is sealingly mounted on the base, the hood comprising two openings through which the conveyor extends when the hood is in operational position. The hood comprises an inner partition mounted mobile between a retracted position and a service position in which the partition defines with the side walls of the hood and the base a main chamber of the enclosure subjected to the action of the heat-diffusion means when the hood is in operational position.

Abstract: The invention relates to a heat-shrinking facility for heat-shrinking sleeves made of heat-shrinkable material inserted onto supports, such as containers, comprising an enclosure, a heat-diffusion means (200) arranged inside the enclosure for supplying the heating means with steam and at least one conveyor for carrying the supports through the enclosure between an intake of the enclosure and an output of the enclosure. According to the invention, the steam-generation means comprises an adjustment means suitable for controlling the steam-generation means according to at least one measurement of the temperature prevailing in the enclosure such as to make the measured temperature tend towards a given set temperature.

Abstract: The invention relates to a device for accumulating flat material in flexible strip form, the device comprising an accumulator box having a bottom on which the strip accumulates, at least during accumulation stages, between two end walls and between two side walls that extend so as to face edges of the strip. The accumulator device includes at least one of the following means: rollers mounted idle close to the bottom and on which the strip rests during accumulation stages; air-flow means for establishing a flow of air within the box towards the bottom of the accumulator box; vibrator means for vibrating at least one of the side walls; and adjuster means for adjusting spacing between the side walls.

Abstract: The present invention relates to a cover for wrapping at least one article, the cover being of the type constituted by a sleeve of heat-shrinkable plastics material suitable for closely surrounding at least a portion of the article or a group of articles. In accordance with the invention, the sleeve is constituted by superposing at least two walls secured to each another by detachable adhesive means, said walls having shrinkage characteristics that are essentially identical, and the outermost wall of the sleeve also presenting, through its entire thickness, at least one cut defining a detachable circumferential strip, said circumferential strip being printed so as to present respective patterns of printing that appear on each of its sides, the other wall(s) also presenting a pattern of printing behind the detachable circumferential strip that appears after said circumferential strip has been detached.
