Spindle mounting for ring spinning machine

In a ring spinning machine, in combination;

• a rail provided with a horizontal flange having a row of spaced-apart apertures;
• a plurality of rigid sleeves with vertical axes respectively mounted in said apertures;
• a plurality of elastic bushings respectively inserted into said sleeves;
• a plurality of upright shafts respectively supported in said bushings, each of said shafts having an upper extremity projecting above the respective bushing and further having a lower end projecting beyond said bushing below said flange;
• a plurality of vertical spindles having lower extremities provided with respective whorls, said lower extremities being rotatably journaled on said upper extremities of respective shafts;
• a pair of retaining rings independent of the respective sleeve fastened to said rail below said flange, said retaining rings elastically engaging said lower end through resilient, annular inserts at locations vertically spaced from each other and from the respective bushing;
• a driving belt stretched above said flange in tangential contact with said whorls for jointly rotating said spindles;
• and
• a plurality of pressure rollers carried on said rail on a side of said driving belt opposite said whorls and offset from said whorls in the direction of belt motion, said whorls having diameters substantially less than 30 mm, said pressure rollers having diameters substantially greater than 30 mm.
