is pulled by a driven roller 48 to a disposal area the roller 48 is driven through an adjustable slip clutch a constant pressure is applied to roller 48 by means of a pressure roller 50 mounted by a bracket on a shaft which in turn is mounted in a frame 52 which pivots about stud 54 mounted to the frame 17 the tension on roller 50 is supplied by a spring 61 the roller 50 and driven roller 48 hold the liner tightly therebetween maintaining tension on the liner from the metering roller 16 past eccentric pin 40 around the applicating tip 56 and through the rollers 48 and 50 this tension maintains the liner in a straight line as it travels about the rollers and tip through the taping head the various shafts driving the eccentrics can be driven by various drive means such as chains or gears a gear train is preferred since it is compact and requires the minimum amount of space the drive for the applicator is illustrated in fig2 and 6 the drive for the applicator is matched to the movement of the conveying mechanism for the substrate to keep the two pieces in proper timed sequence this is obtained by a drive belt or chain 70 driven from a drive pulley not shown supported on the conveyor frame.
