Abstract
Process and device are provided for the automatic adjustment of the rotational speed ratios among the operating elements of a draw frame. The invention utilizes a drive for a draw frame which is less expensive and at the same time achieves a higher degree of automation and precision for the adjustment of the rotational speed ratios between the operating elements. The total required power to be supplied to the operating elements of a draw frame is divided up between a main motor and several separate motors. The distribution of the required power capacity is such that the main motor delivers a constant required power which represents the major part of the total required power. All the separate motors which deliver selectively variable required power, together furnish the lesser share of the total required power. According to the device, the mechanical gear coupling of all operating elements among each other is at the same time coupled to individual drives for all operating elements.
