Abstract
A crop baling machine of the type for producing round bales and in which a cylindrical bale forming compartment receives crop material from a pickup device, the bale-forming compartment being defined by an endless apron which extends around inner and outer sets of guide rollers. The endless apron also extends respectively around drive sprockets and takeup guide sprockets which are spaced apart to provide an inlet to the bale forming compartment, the takeup guide sprockets being mounted for limited movement against springs to maintain the apron taut but also permit limited expansion of the inner portion of the apron which extends around the inner set of guide rollers when the bale forming compartment is filled to a desired degree, and the movement of the takeup guide sprockets causing additional mechanism to disconnect the pickup device from the power source which drives it and thereby automatically prevent structural damage to the machine.
