268,455. Courtaulds, Ltd., Glover, W. H., and Topham, C. F. Jan. 7, 1926. Spinning machines; spinning machines with twisting- arrangements at delivery; connecting continuously delivered material to the winding- means; spindle apparatus; moistening and sizing. - A dry-spun thread of artificial silk is wound in a centrifugal spinning box, and the end is introduced into the latter by means of a current of air or other gas. Thus, the thread A after passing round a godet B, is led through a guide a<1> to a groove d formed in the down-turned, end of a pipe D, and from this point it is returned to the godet, so forming a loop C; the end of the tube D is immediately above the guide funnel E of a spinning box F, such as that described in Specifioation 23158/00; in order to introduce the thread into the box, the tube D is given a sharp downward movement so as to break the loop and at the same time a current of air is passed through the tube so as to blow the end of the thread down the guide E into the box F. It is convenient to moisten the thread on its way to the spinning- box by passage over a damped brush, and the thread may also be sized as by passage over a moistened surface or through a brush. The cake may be removed bodily from the box preferably after heating for a short time. Alternatively, the thread may be wound out of the box preferably through the funnel E, which is then preferably held stationary with its end opposite the centre of the cake; during winding off, the box F may be held stationary or it may rotate, in which latter case an additional twist may be put on the thread.
