Abstract (en)
[origin: EP0235093A1] Automatic control apparatus for controlling the tension of a fabric as it passes over the barrel of a carding and napping machine has a first electronic unit (10) for controlling the speed of a first variable speed drive (3, 13) which feeds the fabric onto the barrel and a second electronic unit (20) for controlling the torque of a second variable speed drive (4, 24) which draws the fabric from the barrel. The two variable speed drives (3, 13; 4, 24) are electrically interconnected in such a way that the second variable speed drive is governed in speed in dependence on the speed of the first variable speed drive by means of a tachometric generator (16) driven to rotate by the said first variable speed drive (3, 13).
