Verfahren und Vorrichtung zur Heisssiegelung von Etiketten auf Behältern.

摘要

A labeling machine for applying labels of heat softenable material to containers comprises a rotating cylindrical vacuum drum (11) which picks up labels (20), in succession at a label receiving station as it rotates, transports each label to a label applying station (12) at which the leading end of each label is applied to a container; means to rotate each container to which the leading end of a label has been applied to wrap the label around the container and to lap the trailing end of the label over the leading end and while so doing to apply pressure to the lapped junction of the leading and trailing ends, and means in the form of a heat applicator located within the drum, extensible through an opening in the drum to bring a head or nozzle (25) into close proximity to the trailing end (20a) of a label during most of the travel of such trailing end between the label receiving and label applying positions and to apply heat during such period to the trailing end to soften the trailing end so that it can be welded by pressure to the leading end.
