摘要:
The present invention relates to a seam protecting device which can be applied to drum grinding or raising machines, for preventing threads connecting adjoining pieces to be processed from breaking, characterized in that the device comprises at least a pair of ring-like elements (1), parallel to one another and connected by means of connnecting beams or bars, adapted to turn about bearings (2) and a drum (3) provided with raising or grinding cylinders (4). To the pair of ring-like elements there is applied a cusp element (8) which, under a normal condition, is located at the bottom part of the drum.

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) forcontrolling 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).

The present invention relates to an improved maintenance raising machine including a safety device for preventing damage as the fabric being raised is broken. The raising machine comprises a horizontal axis drum (2) which can be rotatably driven about its rotary axis (2a) and which supports, on the periphery thereof, a plurality of raising cylinders (3,4), which have cylinder axes parallel to the drum axis (2a) and are rotatably driven about the respective axes. With a portion of the drum (2) are associated cleaning brushes (6,7) which can operate on the raising cylinders (3,4) for cleaning the latter. The cleaning brushes (6,7) are mounted on a controllably driven support (8) which can be displaced toward or away from the drum (2) in order to facilitate the maintenance of the raising machine and to prevent damage to the brushes (6,7) or the raising cylinder covers (5) as a fabric being raised is accidentally broken.
