Abstract
A tying mechanism on a baler having a bale forming chamber incorporates an improvement for removing end play between the components of the tying mechanism. The tying mechanism includes an elongated drive shaft and a plurality of side-by-side units mounted along the shaft and operable to carry out tying of strands of material that band a bale being formed in the bale chamber. The tying units are movable axially along the shaft for adjusting them to predetermined operational positions relative to one another. The improvement relates to a pair of annular adjustment cams being mounted about and releasably secured to the shaft between the units. The cams of each pair thereof engage one another and are individually rotatable, upon release of the securement thereof to the shaft, for movement to various angular positions relative to each other about the shaft to vary the width of the space occupied by the pair of cams and thereby adjust the units relative to one another and maintain the same at the predetermined positions along the shaft.
