[Problems to be solved by the invention]
The twain feeding device w in the above-described conventional roll baler A is pulled out from the twain roll a, and the twain brake b → twain pulley c → twain feeding roller d → twain guide metal fitting e → bundling width fixing metal f etc. When the tension applied to the twain t wound around the circumferential surface of the roll bale B in that order is pulled out from the twain roll a, there is almost no tension, and the tween delivery roller d is exited through the twain brake b. Slightly small tension is applied during the period until the tween guide fitting e is engaged and the roll bale B is passed through the tween guide fitting e due to frictional resistance caused by contact with the tween guide fitting e. A moderate tension that increases or decreases according to the angle at which the twain t is bent is given by the moving position of the metal fitting e. Inner fitting e is moved to the end portion side in the axial direction of the roll bale B, by contacting the TWAIN t further bundling Habake' fittings f, so that given the large tension by greater frictional resistance.
[0009]
For this reason, if the twain feeding device w is provided in duplicate in correspondence with the left half side and the right half side of the roll bail B in the axial direction, In the middle of the range from the corresponding part to one end, the tightening of the tween t wound around the peripheral surface of the roll bale B is weak, the tightening is strong on the end side, and the tightening is weak in the middle of the above range. There is a problem that causes the phenomenon of loosening in the binding.
[0010]
As a countermeasure for eliminating this phenomenon, it is only necessary to increase the tension of the twain t at the position of the twain feeding roller d by adjusting the twain brake b. Since there is a limit to the driving force of M, there arises a problem that the tension of the twain t cannot be increased more than before.
[0011]
Further, the tension applied to the twain t must be within a range that does not cause the twin t to be cut, and at the end of the roll bail B in the axial direction, the twain t is connected to the twain guide fitting e and the bundling width determination fitting f. Since the tension applied by both is limited, there is a restriction that the tension cannot be increased beyond the tension applied to the twain t at the shaft end of the roll bail B.
[0012]
The present invention has been made in order to solve the above-mentioned problems occurring in the conventional means, and the end of the roll bale B is applied to the twin t wound around the circumferential surface of the roll bale B by the twain feeding device w. A tension equal to or slightly smaller than the tension applied when winding on the part side is applied to the central part in the axial direction of the roll bail B to enhance the tension of the twain t wound around this central part. It is an object of the present invention to provide a new means for preventing looseness in the binding of the peripheral surface of the roll veil B by the twain t at the site.
[0013]
