Abstract
A twine brake device is so controlled that during an initial period in which the bale chamber is not filled with harvested material, the average tension in the twine, wire or cord is higher than during a second period in which the bale chamber is completely filled with harvested material.
Claims11
A method for controlling a twine brake device of a rectangular baler comprising:
- controlling the twine brake device during a first period in which the bale chamber is not completely filled with harvested material such that the average tension in the twine, wire or cord is greater than during a second period in which the bale chamber is completely filled with harvested material;
- and
- wherein the controllable twine brake device comprises first and second twine brakes, the second twine brake cooperating with the first twine brake to exert an additional braking force on the twine, wire or cord when the bale chamber is not completely filled with harvested material and to build up on the basis of this additional braking force an increased tension in the twine wire or cord.
A rectangular baler, comprising:
- a bale chamber;
- one plunger oscillating in the bale chamber;
- a knotter device for knotting twine, wire or cord;
- at least one controllable twine brake device comprising a first twine brake to increase the tension in at least one twine, wire or cord;
- and
- a controller programmed to control the twine brake device in a first period in which the bale chamber is not completely filled with harvested material such that the average tension in the twine, wire or cord is greater than during a second period in which the bale chamber is completely filled with harvested material;
- and
- wherein the controllable twine brake device further comprises a second twine brake device, the second twine brake device cooperating with the first twine brake to exert an additional braking force on the twine, wire or cord when the bale chamber is not completely filled with harvested material and to build up on the basis of this additional braking force an increased tension in the twine wire or cord.
