Band Printer Lubrication System

The wear problem caused by a type band dragging across a stationary platen is reduced by applying a wax-type material to a portion of the rear surface of the band.

A printer apparatus comprises endless metal type band 10 wrapped around friction drive pulleys 11 and 12. A platen 13 is located behind band 10 opposite print hammers 14. Platen 13 has a relatively hard surface against which band 10 drags during its continuous rotation by the drive pulleys 11 and 12. Lubricant wax stick 15 in fixed container 16 is located inside band 10 in advance of pulley
12. The end of stick 15 is narrower than the band and is positioned so that lubricant is applied in the center of band 10 behind the characters. A bias spring 17 may be used for continuous application. Alternatively, stick )5 may be periodically disengaged from band 10 to control the thickness of the lubricant layer.

By applying wax to only a portion of the band surface, the friction drive is not adversely affected while extending the life of the band 10.
