This invention relates to an object-powered
pressure-sensitive adhesive tape dispenser and
applier which utilizes the driving power of the
moving objects to which the tape is applied for
operating the dispensing mechanism. Each op
eration of the applier results in the automatic
positioning of a piece of tape ready for applica
tion to the next object.
The preferred embodiments utilized the “cutter

between the feeding means and the applier,
whereby the object-impelled applying stroke of
the applier performs the heavy work of feeding
(withdrawing and cutting) while the lighter task
of positioning the severed tape is done later by
a spring-impelled return stroke of the applier.
This permits the ?nal positioning of a succeeding
piece of tape to be delayed until the preceding
object is clear of the machine and at the same
