ABSTRACT:
A baling machine has belts which define a chamber in which a bale is formed. The belts are trained over rolls including belt take-up rolls mounted on a pair of pivoted arms moved by a piston and cylinder units connected thereto at first ends and connected at second other ends to a gate of the machine.
In order to have the choice of producing a bale with a soft core each arm has a plurality of connection points one of which is close to the arm pivot and a geometric line through the axis of each unit will pass near the arm pivot so that tension applied by the unit to the belts during formation of the bale core is insignificant. The angle between the axis of each unit and a line joining the connection point of the unit to the gate and the arm pivot is zero to seven degrees, and desirably three to four degrees.
