Abstract
A tape head assembly—which tapes flaps of boxes on a conveyor—includes power-assist functionality to stretch a first spring used to power a trailing roller to press tape against a trailing case sidewall of a case. A force by the case moving on the conveyor acting upon a leading roller may provide some of the energy to stretch the first spring. However, a roller-assist air cylinder uses compressed air to assist or fully stretch the first spring. A knife assembly may be used to cut the tape applied to a case. A second spring may be stretched by the force of the moving case acting upon a knife arm. The second spring may be used later operate the knife blade. However, a knife-assist air cylinder uses compressed air to assist or fully stretch the second spring. Both assist assemblies may be turned off to operate the tape head in a conventional manner.
