Process for obtaining or winding the depolarization mass of carbon electrodes. Patented in the German Empire on August 8, 1926.

The manufacture of flashlight batteries and anode batteries is a definite one Mass item, so all manufacturing operations are required to do so are as easy to set up as possible to ensure high performance even for unskilled workers is achieved. Obtaining or wrapping the depolarization mass on the carbon electrodes Hitherto happened in such a way that fabric, paper or the like around the depolarization mass is wrapped around and as a security again with twine, string or the like.

wraps and is knotted, and that is why the wrapping is done around the depolarization To hold the mass together and to protect it from damage during manufacture. The present procedure and the facility for carrying out the procedure are intended to Obtaining or wrapping the depolarization material of carbon electrodes for flashlight batteries and anode batteries, etc. with cloth. ίο paper or the like. Relieved, improved and a greater acceleration in manufacture can be achieved.

The invention consists essentially in that the carbon electrode with the winding material is pressed through a suitable die, which can also be heated, whereby • the material is firmly attached to the depolarization mass; Furthermore, the free-standing ends of the winding material forming at the lower end of the depolarization compound are folded over and pressed together by a punch dipped in pitch or resin compound or the like, whereby the free-standing ends are firmly placed on the bottom of the depolarization compound and stick together, which is the Wrap material gives a firm cohesion. The fabric used to cover the depolarization compound is cut so large that it completely covers the depolarization compound and has a hole in the middle through which the carbon pin fits comfortably.
On the drawing:

Fig. 2 is a plan view of the device; Fig. 3 shows the stamp for pushing out the electrode and

Fig. 4 shows a stamp with which the resin or pitch mass is pressed on. When the depolarization mass α is to be wrapped, the carbon pin 5 is pushed through the material c so that the material rests on the upper surface of the depolarization mass. Then the electrode with the substance is pressed into a die d, which is provided with bores e , which have such a large diameter that the electrode with the substance can be pushed through comfortably with little pressure. During the process, the electrode is pushed into the die until the electrode is completely enclosed by the die. In this way, the material is pressed firmly against the depolarization compound, especially when the die is warmed up a little, and the ends f of the material exposed at the lower end of the depolarization compound are pressed by a stamp which has previously been dipped in a resin or pitch compound specially produced for this purpose is pressed together bent over with a pressure and thereby glued to one another. Then the fully wrapped electrode is completely ejected from the die with a second punch. Above the matrices, there is an enlarged bore and several depressions g, in which the wrapping material is evenly distributed, so that the wrapping becomes uniform. The matrices can be used individually or several arranged next to one another in this method. A machine rotating intermittently can also be used in this method, which of course results in higher performance. When the electrode is ejected from the die, it falls into a box h placed under the dies.
