Definitions
- the present invention relates to an improved apparatus for the continuous production and liquid treatment of threads (within which term, as used in this specification and claims, are included filaments) more particularly of artificial threads.
- the present invention consists in the provision of flanges which, instead of extending continuously around the respective rollers, are provided with suitable gaps through which the loops of thread will pass during spinning or when the thread traverse is being started or re-established.
- the rollers carrying the thread to be treated are provided with one or more flanges, each of which is interrupted by a gap.
- the lower roller may be furnished with a gapped flange situated at the end of the acid treatment zone, and the upper roller with a gapped flange some distance farther along.
- the gaps are preferably of a width not less than one-sixth of the length of the flange (i. e. of the circumference of the roller), thus subtending an angle of not less than 60 at the axis of the roller at that point,
- the gapped flange may be turned out of the solid during the manufacture of the roller, or may be separately made and attached to the roller, or may be in the form of a split ring of springy material sprung on to the roller.
- Figs. 1 to 4 are fragmentary views in side elevation of rollers or godets provided with gapped flanges in various desirable forms and arrangements within the invention, in which wherever the path of the thread is indicated, the showing is for an upper roller;
- Figs. 5 and 6 are fragmentary views of a pair of rollers illustrating how the thread cross-over from one side of a flange to the other is permitted by the flange gap;
- Fig. '7 shows a portion of another pair of rollers embodying the invention.
- two gapped flanges I, 2 are provided in spaced relationship on a guide roller 3, the gaps, 4, 5, in these flanges being disposed not immediately opposite each other but in staggered positions for good separation of the treating zones :on the roller.
- a single flange, 6, is provided with a gap, 1.
- Fig. '7 shows diagrammatically a portion :ofa 7 pair of thread-storing, thread-advancin rollers l2, l3, in operation.
- the flanges may be convex :gor .zprismaticizin cross-section, and are preferably Ytchamfered: on both sides or at least on one side sothat the thread may pass smoothly through the gap.
