An improved plunger assembly is provided for use in a splicing tape dispenser-applicator of the type which comprises a plunger and a guide channel in which the plunger reciprocates. The improved plunger assembly comprises a plurality of low-friction bearing devices carried by the plunger and arranged so as to slidably engage at least one member which defines the guide channel. The low-friction bearing devices reduce friction wearing of the plunger and the at least one channel-defining member.
