摘要： Bales are successively formed in the baling chamber of the machine by intermittently packing an additional charge of new material against the trailing end of a forming bale to progressively push the bales toward the discharge end of the chamber. When the bale reaches its predetermined size, a needle swings across the bale chamber behind the trailing end of the bale and presents a binding strand to a knotter. The knotter unites the presented end of the strand with an end previously held by the knotter during a packing cycle such as to form a secure, tied loop about the bale. As the needle retracts from the knotter, it places a new length of strand across the bale chamber in preparation for the loop around the next, succeeding bale, and it is during such retraction of the needle that a slackening device draws a supply of slack in the strand and lays the same along the proximal side of the preceding bale. Hence, as the next bale is incrementally advanced through the chamber, the slack supply becomes progressively depleted as it strings out along the forming bale. Thus, until the slack supply is entirely consumed, the strand need not be pulled through the interface between the preceding and forming bales in order to string out the strand along the bale.
