ABSTRACT:
Labeling machine for applying labels of heat softenable material to containers comprising a rotating cylindrical vacuum drim which picks up labels in succession at a label receiving station as it rotates, transports each label to a label applying station 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 into close proximity to the trailing end 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.
