HEILEMANN in GEBHARDSDORF (Silesia). Process for the production of bulbous vessels from paper waste.

Patented in the German Empire on July 31, 1877.

The purpose of the method described below is to make bulbous paper vessels made of cheap material to produce, from the waste paper, such as those in the form of strips in the Paper production (as sections), at the telegraph stations (as written strips), occurs when wallpapering (as wallpaper sections) etc.

The accompanying drawing shows the mechanical device as it is designed by the inventor for the vessels to be spun from waste paper. The core of FIG. 1 (drawn on average) serves as the shape for the object to be manufactured thereon. It consists of two disks bb ' (Fig. 1), circular boards, which have twelve holes to accommodate as many ribs r r. are provided; the pins ζ ζ of the ribs contain gear segments (Fig. 3) made of iron at their front end. The disks are firmly connected to one another by an axis c, which contains a continuous cavity with a square cross-section L (FIG. 3); at the front end the axis protrudes by about 4 cm, and on this projection ν (Fig. 1) carries the gear Z (Fig. 3). All twelve segments mesh with the toothed wheel, so that, for example, one turn of the toothed wheel to the right causes the ribs to turn to the left about their axis. When the ribs are rotated through an angle of 90 °, their bulbous part, owing to the curved construction, retracts so far that they form approximately a straight cylinder qu qu (Fig. 2). Two wing lugs located on the gear wheel // (Fig. 1 and 3) serve to handle the gear wheel, as well as a slide 0 and which in the slot / sliding mandrel D (Fig. 3) is used to lock the ribs when the core is in use. The square cavity in the axis connecting the wooden disks is used to hold a square iron rod, which is inserted into a frame A (FIG. 4) and rotated; like the object to be turned on a lathe, the core then turns with the iron rod. On the ribs rr (Fig. 1) the outer surfaces of the ends II and / ¹ Z ¹ protrude somewhat above the central part. This middle part determines the inner height of the vessel, and by the protruding ends the bearings resp. Groove formed for the floors η η '(Fig. 2).

The method of manufacture is as follows: Paper strips R wound into rolls (Fig. 4) are hung over the core c , these take the way over the guide rollers aa ', the container with adhesive, roller K, felt roller F and core C. The ends of the strips you stick to the core and turn it by hand, so that the paper strips wind up on it. The paper strip, after it has been provided with adhesive by the roller K , runs over the raised edge of the container x in order to strip off the excess adhesive from the same, then over the felt roller F, which makes the strip cardboard and better adherent. The mechanical device shown in side view in Fig. 4 is such that the worker has everything conveniently at hand and in sight, namely the adhesive side of the paper strip. The worker spinning the wall of the vessel has to direct his attention to the fact that the strip of paper covers the core equally often in all places. In order to achieve this, he pushes the latter on the rod A as required from one side to the other, and thereby achieves a uniform thickness in the wall. When the worker has finished spinning the wall of a vessel, he takes the core from axis A (Fig. 4), turns the gear wheel of the same by means of the handle // (Fig. 1), which manipulation approximates the manufacture of one. a straight cylinder resembling body qu qu (Fig. 2), and thereby allows it to be removed from the wall WW (Fig. 2). The wall is then smoothed on a press with appropriately conical rollers - the roller, which acts as a stamp, can also be provided with a relief pattern in order to produce a deer pattern on the outer side of the vessel - and handed over to another worker to insert the bottoms. The bottoms dd (Fig. 2 with dots) are also made from scrap paper and cut by throwing presses or by hand, provided with glue on the edges and placed on the approaches which are formed by the protruding ends of the ribs. Then an adhesive is applied

See cardboard strips pp (Fig. 2) placed flat on the side wall, and now the still protruding edge of the wall turned inward. The average of barrels made in this way corresponds exactly to that of the wooden barrels, in that the bottoms are also in grooves, as with the wooden barrels.

The closure of the barrels depends on the purpose for which they are to serve; as well it is the case with the application of the glue and the preparation of the vessels with insoluble, substances that do not let the liquid through. Cut from one floor a lid with a conical edge, these paper barrels are particularly suitable for Post-Packet etc. shipments; you put the lid on the opening and glue it in enough Large piece of paper with an address on it. If you cut the opening even larger, and If you put a button on the lid, then such a Fafs should be used as a stand for domestic use as well as for pre-food stores. In addition, these barrels can be used for Set up many uses by putting the paper up against all destructive influences to a certain extent, and one can give the vessels manifold properties which the wooden casks give unequal would be more difficult. So z. B. in barrels for transport both, and for The storage of explosives: After the wall up to the protruding ends the rib is spun using ordinary glue, it is removed from the The core is taken and dried, then it comes back on the core, is covered with an asphalt solution painted over, simply spun with dry strips of paper and this latter manipulation repeated a few times; then you let the asphalt solution dry and bring it now a few sheets of ordinary glue over them, which are then secured against fire Preparations such as metal salts etc. can be impregnated. Such barrels are for inclusion better suited for ignition wares than wooden casks, since they come from one, as it were And there is no question of leaking due to drying up can.
