Apparatus and methods for applying labels

摘要

An apparatus for applying labels to moving articles includes a vacuum drum mounted for rotation about a central axis and a manifold having a first passage adapted to be in fluid communication with a first vacuum line. First apertures in the vacuum drum are in communication with the first passage of the manifold such that vacuum pressure may be developed at the first apertures to hold labels on selected portions of the vacuum drum. Second apertures in the vacuum drum are adapted to be in communication with a second vacuum line. The second apertures are positioned for location behind the trailing edges of labels held by the first apertures so that excess adhesive applied to the labels may be removed through the second apertures.
