ABSTRACT:
An automatic sliding-weight scale arrangement with a hinge-supported scale beam. A continually motor-driven friction drive moves a sliding weight along the scale beam. The friction drive has at least two frictional elements, one of which is attached to the frame, and the other is attached to the scale beam. One of the frictional elements, furthermore, is supported exclusively by one or several rotary friction units and is displaceable in a rotationally and lengthwise manner for moving the sliding weight. A lengthwise displaceable friction roller is supported by a rotary friction unit located vertically underneath it, as well as by a rotary friction element on one side and an additional friction unit on the opposite side. Two of the friction units are mounted on the scale beam, and the friction element is mounted on the frame. The friction unit may be in the form of two coaxially-spaced friction disks of the same size.
