There is disclosed an improved circular sliver knitting machine having increased carding capacity for increasing the amount of sliver which can be carded and fed into the knitting machine. A mounting ring is fixed on an upper bed plate fixed to the sliver knitting machine frame. A plurality of sliver feed assemblies are supported on a sliver feed mounting plate secured to the upper bed plate. The sliver feed assemblies interconnect to a ring gear mounted in surrounding spaced relation to the mounting ring. The sliver feed assemblies card and feed sliver yarn to the knitting needles as the ring gear is turned. A bearing assembly for allowing rotation of the ring gear relative to the mounting ring while withstanding radial and tangential loads imparted on the ring gear includes at least one wire race extending along the outer surface of the mounting ring and at least one wire race extending along the inner surface of the ring gear. A plurality of ball bearings engage the wire races for rolling along the wires as the ring gear is turned.

Métier circulaire de tricotage avec rubans, à fonction de cardage améliorée en vue d'accroître la quantité de rubans pouvant être cardés et alimentés dans le métier à tricoter. Une bague de montage est fixée sur le bâti supérieur, lequel est monté sur le cadre du métier. Plusieurs ensembles d'alimentation en rubans s'appuient sur une plaque de montage installée sur le bâti supérieur. Les ensembles d'alimentation en rubans sont interreliés à une couronne montée autour de la bague de montage, mais sans contact avec celle-ci. Sous l'effet de la rotation de la couronne, les ensembles d'alimentation cardent et amènent le ruban transformé en fil. Un ensemble support permettant à la couronne de tourner par rapport à la bague de montage et de supporter les charges radiales et tangentielles qui lui sont imparties comprend au moins une voie de roulement formée de fils métalliques s'étendant le long de la surface extérieure de la bague de montage et au moins une voie semblable le long de la surface intérieure de ladite bague. Plusieurs roulements à billes s'engagent dans les voies de roulement et se déplacent le long des fils métalliques sous l'effet de la rotation de la couronne.
