Description

The invention relates to a method for producing spinning pots, in particular especially for the production of artificial silk, through which spinning pots are obtained in a simple manner, the centrifugal stresses at high speeds and the corrosive Can withstand the influence of acid.

Attempts have been made to improve the strength of the spinning pots made of synthetic resin molding compound to increase by metal inserts, without, however, to a satisfactory result get there through, the metal inserts as a result If the weight distribution is not completely uniform, this will cause operational disruptions can. There are also spinning pots made of non-metallic material to increase the strength with metal parts surround, namely these metal parts in the form of a bandage on the smooth walls of the pot forced or shrunk. These bandages are available in both band and also been used in wire form. Spinning pots produced in this way can, however, meet the requirements do not correspond, as centrifugal forces occur with the honing such bandages placed around the wall can loosen and slide off, so that the Protection or cohesion of the pot is called into question. To get through the centrifugal To achieve the high mechanical strength required for stresses at high speeds, one has the Whole spinning pot made of metal wires impregnated with synthetic resin and wrapped with fiber built up. Such a structure is cumbersome and expensive, after all, and it can be implemented according to the invention by the following The described four drives achieve the same strength and centering of the spinning pot with much less effort and expenditure on steel wire.

The invention consists in that the outer wall ■ when making the spinning pots of the partially hardened preform made of synthetic resin molding compound with all around running indentations is provided by a metal wire covered with synthetic resin impregnated fiber fabric is wound, is filled. With the application of heat and pressure, the Whole for completion expedient in the form used to produce the basic shape inserted and hardened.

In Figs. 1 to 5, the individual stages in the manufacture of a spinning pot are illustrated.

Fig. 5 shows a single part. The method according to the invention takes place in the following way. First, a rough shape of the spin pot (Fig. 1) is made ao made of the malleable material. This raw form generally has the shape of the finished Spinning pot. The side wall 1 can consist of continuously continued layers Cotton fabric and made by winding a strip of appropriate Width can be formed on a rotatable core. The cotton fabric is in front of the Winding impregnated with synthetic resin and applying the bobbin in a form pressed by heat and pressure, but only so long that the resulting body is not yet completely hardened. The thus obtained Spinning pot is' subjected to further processing by cutting into the wall Grooves 6 and slots 8 cuts so that between the grooves rings 9 in which the Holes 2 are drilled, arise. At the same time, grooves 10 and 11 are also used Receipt of the ends of the reinforcement wire provided. Now one is impregnated with Cotton braided wire that is treated with a synthetic resin with its put one end into the groove ι ο and underneath the required tension wound in the grooves 6, so that the successive Turns of the wire are close together and the wire from one groove to the other runs through the slots 8. The other end of the wire is then placed in the lower groove 11, as shown in Fig. 3 can be taken.

The grooves 10 and 11 are then with "filled with malleable synthetic resin until the ends of the wires are covered. The resulting The body is then placed in a compression mold, for example in the one for producing the basic shape used, 'inserted and subjected to hardening under heat and pressure. The spinning pot then has a completely smooth surface, and the steel wire is completely with covered with an acid-resistant coating.

After completing this process, the outside of the spinning pot is covered with a thin woven fabric, such as a thin ribbon, wrapped around it. This is suitable especially a cotton ribbon of 0.15 mm Starch previously treated with a binder such as a synthetic resin has been. The tape is wound around the outside of the spinning pot that the successive turns overlap. The winding of the tape is in the Fig. 3 illustrates and indicated by the reference numeral 12. The wound up Tape thus represents a thin, complete coating with a smooth surface Fig. 4 is the ribbon on the completed spin pot (labeled 13.
