Abstract

A tape head apparatus for applying sealing tape to cartons moving thereunder on a conveyor has rollers as part of roller assemblies for rolling the tape under pressure onto the leading face, top surface, and trailing face of the carton. The rollers, assemblies, which are carried on a support frame, and are biased toward their extended position, with the biasing force creating the pressure of the rollers on the tape and the carton. The biasing force is augmented by a pressure enhancer which is actuated while the rollers are applying the tape to the top surface, and the augmented force remains until the tape has been applied to the trailing face of the carton. A cutter cuts the tape prior to its application to the trailing face, leaving a length of unapplied tape sufficient to apply to the trailing face.
