Abstract

Fully automated method and apparatus are provided for labelling containers, including supplying and applying labels. A supply provides a web of preprinted labels which may be pre-perforated for easy separation. This web of labels is fed past a sensing device and an adhesive applicator. A clamp temporarily clamps the web in response to signals from the sensor during separation of the leading label from the web. The leading edge of each label is fed to a label-engaging station with the adhesive-coated surface facing the container to which it is to be applied. Conveyor means continually transport a sequence of individual containers to said station where the respective container contacts the adhesive-coated label end. Immediately, the container begins to be rolled in a labelling channel defined between a continuously revolving belt having a friction surface and an opposed stationary wall for wrapping the label firmly around the container rolling along this channel. Pinch means at the upstream end of this channel drive the respective container into firm contact with the adhesive-surface of the label end while pressing the outside of the label against the revolving belt, thereby commencing rolling the container within the channel. After a predetermined amount of wrapping, the web is temporarily clamped, and the label is separated from it. Following the label separation, the container continues to be rolled along the channel for completely wrapping the label securely. In an alternative embodiment, the label so wrapped may be heat sealed.
