A method of arranging twine around a bale of straw or hay formed by pressing in a baling machine in which twine is fed from two separate bobbins, and, while pressure on the bale is maintained, one knot is laid in both pieces of twine for tying off the bale and another knot as starting knot for a following bale. The time periods of the formation of the knots overlap. The knots formed are noose type knots. The knots are formed under substantially no tension, so that the bales can be pressed with a considerable pressure, and a resulting increased density, without affecting the process of forming the knots or the firmness and stability of formed knots. Apparatus for binding bales in a baling machine comprising means for supplying twine for each twine loop, from two separate bobbins, and first and second rotary driven knotters. Preferably the axes of the knotters are located on opposite sides of a common plane in which the pieces of twine are supplied and the centerlines of the knotters are in radial direction with respect to a common knotter drive spindle, and they are driven by a pair of discs each provided with a toothed sector.
A method arranging twine around a bale formed by pressing in the bale chamber of a baling machine by means of a press plunger, in which twine is fed from two separate bobbins, a starting knot is laid between the twine ends and the twine is arranged in the bale chamber so as to extend across the front of the bale remote from the press plunger, the bale is pressed and the twine is drawn from the bobbins during pressing so that one piece of twine comes to lie along one longitudinal side of the bale and another piece comes to lie along the opposite longitudinal side, after completion of the bale one of the said pieces of twine is carried across the back of the bale by means of a needle which performs a reciprocating movement across the back of the bale through the press plunger, and, while pressure is maintained by the press plunger, two knots are laid in both pieces of twine, one knot for tying off the bale and another knot as a starting knot for a following bale, the time period of the formation of the said other knot unit its completion overlapping the time period of the formation of the said one knot until completion thereof.
Appartaus for arranging twine around a bale formed by pressing in the bale chamber of a baling machine by means of a press plunger, said baling machine comprising means for supplying two pieces of twine from separate bobbins, the apparatus comprising first and second rotary driven knotters, means driving said knotters in overlapped sequential timed relation.
A baling machine, comprising a bale chamber with a press plunger movable therein, means to support at least two separate bobbins for the supply of twine, at least one needle to form a loop of twine around a bale formed by bringing pieces of twine from the at least two bobbins together, and one knotting mechanism for each two bobbins of twine, said knotting mechanism comprising two rotary driven knotter heads, means driving said knotting mechanisms in overlapped sequential timed relation.
