Abstract

1344782 Air bearing BARMAG BARMER MASCHINENFABRIK AG 7 July 1972 [9 July 1971] 31868/72 Heading F2A A yarn roller comprises a tubular roller casing 7 rotatably mounted on a spindle 1, the spindle having a large diameter portion 6 within the roller casing, there being an axial duct 3 in the spindle for supplying compressed air which is fed to the space between the spindle and casing via radial openings 4 in the spindle. Circular end plates 8, 9 are provided in the roller, whose interal diameter is smaller than the external diameter of the large portion of the spindle, the plates having air outlet ducts 12, 13 which are arranged at regular intervals on a circle concentric with the axis of rotation and which are oblique to the axis of rotation. Air, which is exhausted from the bearing through the ducts in the end plates, serves to drive the roller. Openings 16 may be provided in the ends of the large diameter portion of the spindle to allow air between the spindle and end plates to form a thrust bearing. The air supply sustem (Fig. 4, not shown) may be arranged to reduce the pressure of the air supplied when the roller is rotating and generating a sufficient air film.
