Abstract

1,177,962. Yarn bobbins. F. STEFFENINI. 7 Feb., 1967 [7 Feb., 1966; 19 Dec., 1966], No. 5892/67. Heading B8M. A tubular yarn supporting body comprises a wall 16 having an outer surface constituting a body of revolution and an inner surface, a plurality of continuously extending spiral ribs 14 integral with and projecting from said inner surface, at least the inner surface tapering from at least one end of the body to at least the centre of the body, whereby the inner diameter of the body decreases from said one end to at least the centre, and each rib having a cross-section tapering from root to tip. A spindle centring means 10 may be provided at the centre of the body. In a preferred embodiment, an even number of ribs is provided, the inclination of the ribs with respect to the axis of the body being between 25 and 50 degrees, preferably 30 and 35 degrees. The outer surface of the body may be cylindrical or frusto-conical.
