Apparatus for applying a sleeve of heat-shrink material (a "band") to a container comprises a rotary drum having a plurality of upstanding heads. A web of banding material is intermittently advanced and lengths cut off, each cut length being held by fingers in the path of a gripper head mounted on the rotary drum. Each head has forward-facing vacuum port through which air is drawn on a timed basis, so that a band 30 will be picked-up and held by one side face as the gripper head passes the fingers. The resilience of the banding material allows the band partially to open out as it is transferred by the gripper head. The rotation of the drum is synchronized to advancement of the containers, so that a held band is rolled on to the top of a container, the container serving to assist in the opening-out of the band, whereat the band is released by the gripper head.
