PATENT OFFICE.

The previously known method for producing with flutes and sleeves provided stoneware or clay pipes by means of extrusion required that the pipes, after they came out of the press mouthpiece, adapted from the pipe circumference Supports held and had to be carried away in trough-shaped troughs to dry. Not until several days later, when

ίο the pipes were dried out, they were pushed on rollers and, almost exclusively in a horizontal position on trestles, in certain Cut lengths, cleaned and provided with sealing corrugations, then put back up to dry out completely will. This cumbersome handling not only made the process of manufacture expensive, it also became the process of manufacture Pipe surface damaged by frequent handling during transport, so that when Cleaning a post-processing was necessary.

The present method significantly simplifies the manufacture of such tubes in that all machining operations take place in direct succession. For this purpose, leaves the tube after its sleeve is pressed in a conventional manner and the sleeve core has been removed, as ι illustrated in the accompanying drawing in Fig., On a wooden or hollow, metal roller d of somewhat lesser diameter than like the of the pipe c , run up. After the pipe has run into the desired length on the roller, it is cut off at the mouthpiece b of the press and the roller is inserted vertically into a plastering machine (FIG. 2). Here, the pipe with its socket surface is brought to bear on a disk h made of sheet metal or other material, which is attached to the lower end of the roller. By means of a suitable drive, the roller with the tube is made to rotate and is cut to the desired length by the knife attached to the lever arms or by appropriately arranged wires, furthermore with the help of corrugated iron η at the tip and in the sleeve with sealing corrugations and finished cleaned.

After the processing has now been completed, the pipes with the roller are in the Drying room done, with the point down and therefore with the sleeve down set up above and lifted the roller with the disc out of the tube. That now The finished tube does not need to be touched again until it is inserted into the furnace.

When the tube is pressed onto the roller, the latter rests with the end without a washer with the help of it; extended central axis d ¹ and with the help of a connecting sleeve e or the like. On a mandrel f, which carries the pipe core and the sleeve core on the mouthpiece, so that the roller is also correctly centered on the pipe to be pressed out. The other end of the roller, on which the

Disk is attached, rests with the extended axis expediently on a trestle or frame g, which can be aligned in the vertical plane to raise the horizontal storage of the roller according to the height of the press.

Claims (1)

Patent claim: ίο methods of pruning, cleaning and corrugation of socketed stoneware and clay pipes, characterized in that that the pipe coming from the extruder runs onto a roller with which it is fed into a plastering machine Standing vertically and with the mirror of its sleeve attached to one on the roller Disc is brought to rest, whereupon the corrugation, cleaning and cutting with subsequent rotation of the roller of the pipe to the required length by means of adjustable tools located on the plastering machine, for Purposes, all operations to complete the pipes in direct succession to be able to make. For this purpose ι sheet of drawings.
