Beschreibung
Zusammenfassung:	The feed system for a coal getting combine works with a face conveyor. It comprises: a traction device located on the combine and having a cylinder-shaped sprocket on the side surface of which a circular spherical-shaped recess is provided, slots being made on both inner sides of the spherical recess, the slots having an involute-spherical surface. Arranged lengthwise of the conveyor is a longitudinally traversable guide bar secured at the ends of the conveyor and composed of a number of separate tubular sections articulated together and provided with open-end holes arranged square with the longitudinal axis of the holes. L'invention concerne l'industrie minière. Le système d'avance faisant l'objet de l'invention est du type comportant un dispositif de traction disposé sur l'abatteuse-chargeuse et un guidage constitué par des sections distinctes articulées entre elles et possédant des éléments d'engrenage avec le dispositif de traction, et est caractérisé notamment en ce que chaque section 6 du guidage 5 est de forme tubulaire et comporte des orifices débouchants perpendiculaires à l'axe du guidage 5, lesdits éléments d'engrenage étant constitués par des axes à extrémités semi-sphériques disposés dans lesdits orifices avec possiblité de rotation libre autour de leur axe et de déplacement limité de chacun desdits axes le long de l'axe de l'orifice. L'invention s'applique notamment aux abatteuses-chargeuses à taille étroite le long du front d'attaque.
