PROTECTION AND CLEANING DEVICE FOR CATERPILLAR COMB OF DRAFTING ELEMENT Russian patent published in 2009 - IPC D01H5/64 D01H13/14 

FIELD: textiles; paper.

SUBSTANCE: device is meant for protection and cleaning of caterpillar combs of the drafting element of textile machine. The device contains rotatable cylindrical brush, which position in relation with the drafting device changes as a result of winding of textile material around the caterpillar. The coiled material is removed with the cylindrical brush that causes increase of its visible diameter and causes the turn of the bearing of the cylindrical brush movable support or a lever. The cylindrical brush is situated on the way of withdrawal preferably as close as possible to the drafting cylinders. The cylindrical brush position may change in relation to the drafting device consequently from the position of comb cleaning till the withdrawal position. The sensor for determination of the cylindrical brush position in relation to the drafting device stops the machine in case of withdrawal of the cylindrical brush as a result of winding of textile material around the caterpillar. The axis of rotation of the cylindrical brush is set on the lever or on the movable base rotating around their axis that is immovable in relation to the machine body and is rigidly fixed with the machine body.

EFFECT: detection of excessive pollution of brush, prevention from mechanic damage as a result of winding of textile material around the caterpillar and increase of the intervals between brush cleanings and, thus increase of machine capacity and reduction of labor cost.
