  • Patent number: 5829346
    Abstract: A baler of crop material which forms bales by encircling compressed crop material with twine. The twine is formed in loops around the bale and knotted. The baler includes a bale compression chamber into which successive charges of crop material are introduced, a plunger for reciprocating movement in the bale compression chamber which serves to compact the charges and advance the compacted charges towards an exit. It also includes a knotter for tying twine in a form stabilizing manner around successive increments of compacted material after they have been compacted to form bales. A knotter position adjuster changes the position of the knotter in order to accomplish adjustment of tension on the twine during compression and before knotting.
