A label on-rolling apparatus for a labeling machine includes a battery or succession of pairs of spaced soft, spongy and resilient rollers, with the rollers in each pair located on opposite margins of the conveyor and separated by a gap which defines a feed path. The rollers in each pair rotate in opposite directions and at different speeds, and the adjacent rollers along the same margin also rotate at different speeds. The speed differential between the rollers in each pair and the speed differential between adjacent rollers on each margin causes sequential counter rotation or rotary oscillation of containers as they move along the feed path through the adjacent pairs of rollers, causing firm pressure to be applied to the surface of the label to firmly affix the label to the container. A modified embodiment of the invention includes one longitudinal row of rollers located along one margin of the conveyor with adjacent rollers in the row rotating at different speeds, and an endless belt having a run located over the opposite margin of the conveyor and driven in a direction common with the conveyor and at a different speed than some of the rollers. |
