ABSTRACT:
The slubbing stopping device comprises a movable part having a magnet and a fixed part having a magnet. One of these magnets is an electromagnet and the other a permanent magnet. The movable and fixed parts can assume an operating position in readiness for clamping the elongate or rope-like fiber material which may be constituted by a silver, roving or slubbing or the like. These movable and fixed parts, when in the operating position, are connected by the magnetic field of the permanent magnet. An electrical energy supply delivers electrical energy to the electromagnet so that the movable and fixed parts can be separated from one another and the movable part assumes a slubbing clamping position. The electrical energy supply powers the electromagnet such that the permanent magnet and the electromagnet, which previously adhered to one another by magnetic attraction, are repelled so as to separate the permanent magnet and electromagnet from one another.
