Abstract: 1,253,192. Twisting head. ELECTROSPIN CORP. 19 Jan., 1070 [24 Jan., 1969; 18 Feb., 1969], No. 2457/70. Heading D1D. A gripping device for inserting twist into yarn coming from an open end twisting head comprises a radially clamp grip 1 through which the yarn can slide and which is mounted in a rotatable grip holder forming a chamber 9, 9a. A pneumatic yarn insertion device 20, 21 is provided downstream of the gripping device and has an inlet 23 into which a yarn end can be sucked and an outlet 22 coaxial with the gripping device 1, the grip holder having a terminal portion 15 which surrounds at least the outlet 22. As shown the gripping device comprises curved flexible filaments 4 mounted in a disc 10 slidable on splines 11 within the support device 3 which is rotatable in bearings 16, 17 and rotatable by a band and pulley arrangement 18, 19. A stationary tube 20 is arranged within the portion 15 and within tube 20 is a further tube 21 supplied with compressed air. When threading up the grip compressed air is passed through tube 21 so as to cause suction at inlet 23 and the yarn end 27 to be drawn into tube 20. Chamber 9a becomes pressurised and the disc 10 is thus lifted to cause a tube 14 on lid 12 to be forced between the filaments 4 and spread them apart. Thus a passageway is produced through which the yarn end is blown. When the end is joined to the open end forming surface the compressed air is turned off and the disc 10 falls to allow the filament 4 to grip the yarn. The rethreading is effected without stopping rotation of the grip holder 3. In a further form in which the grip holder needs to be made stationary for rethreading the filaments 35 (see Fig. 5), of the grip are mounted in a head which is radially slotted to allow the filaments to be radially displaced. In addition it is formed at one side with a sector shaped slot 38. Thus when the yarn end is blown upwards from the outlet of pipe 20 it passes through slot 38 and when tension is placed on the yarn it is displaced sideways forcing a way through the filaments 35 until it lies centrally of all the filaments and is symmetrically gripped. The grip holder 3 can then be rotated.

The carbon fibre content, from 2% to 25% by volume may be varied along the rod to adjust the flexibility. The handle may have up to 35% carbon fibres to permit a smaller diameter.  A rod is formed by placing bundles of carbon fibres 13, Fig. 1, or a woven tape 32 (Fig. 3, not shown) parallel to and spaced from the edge 14 of a trapezoidal resinimpregnated glass fibre cloth 11 and wrapping the cloth round a tapered mandrel which is generally removed but may be of light metal alloy and left in place. This forms a tube with carbon fibres sandwiched between glass fibres to which rod fittings are attached after curing the resin. Alternatively (a) the glass fibre cloth has selected warp threads or a central band of threads replaced by bundles of carbon fibres threaded into or lightly sown to the cloth, (b) a carbon fibre cloth is wound between layers of glass fibre cloth, or (c) a braided carbon fibre tube is stretched over a pre-formed glass fibre resin blank.  To form a tapered rod in which bundles of carbon fibres are equally angularly spaced throughout its length, the bundles of carbon fibres are placed into the grooves 42, 43 (Fig. 4, not shown) of a jig plate (41). The fibres are picked up by pressing them against a tacky glass fibre/resin cloth or by ironing the cloth against them. The carbon fibres may be prepared as disclosed in Specifications 1110791, 1166252 and 1195219.
