<p>Apparatus for applying a sleeve 30 or 31 of heat-shrink material (a "band") to a container 23 comprises a rotary drum 21 having a plurality of upstanding heads 24. A web of band materials is intermittently advanced and lengths 30 cut off, each cut length being held by fingers 29 until picked up by a head 24 on the drum 21. Each head 24 has a vacuum port through which air is drawn on a timed basis, so that as a head picks up a band 30, the band is held by the head until the band is to be released, on a container top. The rotation of the drum 21 is synchronised to advancement of the containers 23, so that a band 31 is rolled on to the top of a container, the container serving to assist in the opening-out of the band. In a modification, Figure 10, the sleeve (40) extends substantially the full length of the container. <IMAGE></p> |
