Title: Improvements in or relating to fibre producing apparatus
IPC: C03B37/065
Filed: 1946-05-30
Abstract: 612,849. Thread guides. THURSTON, A. P. (Owens-Corning Fiberglas Corporation). May 30, 1946, No. 16455. [Classes 120(ii) and 120(iii)] [Also in Group XXIII] In apparatus wherein a plurality of fibres are maintained by a guide at a required lateral spacing differing from that determined by the supplying source, the guide is threaded by a device which is movable to bring two angularly positioned grooved portions alternately into engagement with the fibres to alter their spacing simultaneously by the required amount. As applied to glass fibre producing apparatus of the type wherein streams of molten glass from orifices 11 in a container 10 are drawn into fibres 12 which are passed into the high velocity flame of a burner 17, and are maintained at a lateral spacing, less than that of the orifices, by a fixed guide 14, the fibres, initially manually formed into a flat bundle with their ends evened up and introduced between the continuously rotating resilient driving rolls 13, are simultaneously directed towards their appropriate spaced channels 15<SP>1</SP> in the lower part of the guide 14 by a device 18 whose comb portion 20, with grooves 22 spaced at their free ends correspondingly to the orifices 11, is first placed against the fibres 12 adjacent the orifices, the device then being moved downwards and rotated through the appropriate angle, e.g., 90 degrees, to transfer the fibres into grooves 21 in the guide portion 19 which is then fixed in the main frame 25; the spacing of the grooves 21 corresponds to that of the channels 15<SP>1</SP>, and as soon as the fibres issuing from the rolls 13 (and temporarily diverted by a plate 24) have adopted this spacing, they are severed by retraction from the guide 14 of a slotted knife 27 previously inserted therein, and the plate 24 is withdrawn to allow the freshly cut ends to enter the channels 15'.

A longitudinally oscillating rod S excited., e.g., magnetostrictively, is held at the centre by a support which is capable of oscillating and whose basic natural frequency is small compared with the working frequency of the rod. The working frequency of the rod lies within the higher harmonics of the support and the damping of the support is such that the differences between successive maxima and minima of its mechanical impedance considered as a function of frequency are negligibly small. The support may be in the form of a short rod at right angles to the oscillating rod (Fig. 2, not shown) or in the form of a circular disc supported at its edges with the oscillating rod arranged axially (Fig. 3, not shown). In the modification shown the support comprises annular flat or conical springs E1, E2 which engage an intermediate element Z connected rigidly to the rod. A suitable material for the support is beryllium-bronze. Damping additional to that inherent in the support may be provided. The Specification describes a known type of magnetostrictive oscillator in which a magnetically polarized rod coupled at the ends to a pair of coils is supported at its centre by a disc which is clamped at the edges and has the same natural frequency of vibration as the rod.
