Abstract

1,239,412. Twist tubes. MACOTEX (MACHINERY) Ltd. 23 April, 1969 [5 July, 1968], No. 32188/68. Heading DID. [Also in Division H2] Twist tubes comprising two outwardly flared trumpet-shaped pieces 10a each extending around an arc of 90‹ and meeting at a small central opening are characterised in that each flared surface has a narrow frictionengendering surface 17a for the yarn, the remainder of the surface being smooth so that negligible friction is engendered thereby: As shown, the narrow surfaces are rings of hard wearing metal or ceramic set into the flared surfaces midway between the perimeter and centre and protruding from the surface. The flared pieces can be rotated by an endless belt engaging their periphery (Fig. 1) or be joined to the rotor 21 of a four pole shaded pole electric motor as shown. The flared pieces can be mechanically braked or the motor may be associated with circuitry which causes the motor to function as a brake so as to stop the flared pieces from rotating. The rotating flared pieces can be supported in ball bearings, plain bearings, a magnetic field, a self lubricating bearing or a self-generating air bearing. Reference has been directed by the Comptroller to Specification 1,042,811.
