Description

Device for fusing pieces of glass, especially optical ones Glasses with the putty blocks that are used to attach them to the sanding bowls. Optical glasses that are ground together in large numbers on bowls (heads) and should be polished. throw previously provided with so-called putty blocks, by means of which they are attached to the so-called putty shell.

One of the most common methods used here is (Let the glasses be placed on a pickled plate and then a piece of pitch on the Glass brings: the warmth of the heated plate causes -then, -lease the piece of glass of pitch intimately connected with a glass. Here, however, the glasses often become excessive strongly heated. get tension and jump dänti during the later P # car processing.

The present Ertin. ung relates to a device in which The fastening of the putty blocks to the glass in a more common: controllable way Kind of happens. = Incidentally, the working procedure was simplified.

The device consists. as shown in the drawing, essentially from a rotatable heating table right. who somehow, z. B. electrical or with Ga: is heated. The worker sits in front of it. what Iie glasses with the ones on Pieces are lying on the '<'% 'armature plate le_-t. The table turns either slowly automatically thrown by the worker from Hatiei @) along with it the foot turned further, so date srlilielalich (put table all around with workpieces lie is leaking. The temperature of the hot plate and its speed of rotation we-1 so tingeriduet that the glasses are fused with the blocks of pitch, if -leg heat table has made one revolution. The worker then takes the produce @ i'erkstücl: e and put new glasses with pitch blocks in their place. The table will be covered with a hood h to which a flue pipe is attached r closes for the pitch mist.

Incidentally, it is not necessary that the place where the glasses are on the hot plate is put on and removed again, is the same; one can Of course, the work is also set up in such a way that a person measures a certain level Place the device on the workpieces and a second person on another Place the finished fused workpieces again.

Putty devices of a type similar to that described above, with a rotating table have also been used elsewhere. The -new thing about the present device is that yaw rotatable table at the same time warming up of the glasses for the purpose of fusing them together, so that at the same time he does the task has to transport and warm the glasses. while with the older acquaintances Devices the rotating table only serves the former purpose.
