Addition to patent no. 25887 of June 29, 1883.

Fatentirt in the German Empire on March 29, 1885. Longest duration: June 28, 1898.

The difficulties encountered in practice when using the so-called continuous Whalebone rods stuck out next to each other and doubled over the entire length stacked waste strips made of whalebone, horn, etc. have led to the invention of the existing innovations or improvements.

The short fuselage strips to be used are so prepared and united with one another that the rods formed from them without end (or ligaments) the regular thickness and suppleness of the simple whalebone obtain. To do this, the ends of the strips are gradually flattened and sloped Sheets of sufficient length are formed, two of which are placed on top of one another, no greater Thickness as a simple whalebone (see Fig. 3).

The dressing of the strips respectively. Bevelling of the ends of the same can be done by hand Filing or the like happen; but it is better to do this work by means of milling, whetstones or to carry out knives which are specially set up for this purpose. To the stripes to connect well with one another and to ensure an intimate union of the same, they become the connection points, as well as regularly wrapped with two threads over the entire length. Depending on the width, the desired appearance and the required properties of the fabric to be fabricated Band or The threads of the continuous whalebone bar become more or less taut and with narrower or wider ones Winding distances around the waste strips to be combined. To the durability To further increase the connection, small, closely spaced notches of shallow depth on the beveled strip ends attached to the latter by the To hold back threads and prevent them from shifting, so that, even under the influence a deliberate application of force, a separation of the strips from each other no longer can take place. Furthermore, the bevels can be coated with glue before their union takes place by wrapping the threads.

To give the product all the good properties of the real whalebone and thereby generalizing its use, the threads used for wrapping become by means of a special one which occurs automatically in the heat according to the manufacturing process Glue is glued to the whalebone so that the finished tape can be cut in any length Can cut pieces without having to fear that the wrapped threads will break detach.

To achieve this result, the adhesive is applied before the threads are wrapped, so that the latter are strongly impregnated with it, to the extent that they are wrap around the strips to unite the previous with the next.

The machine illustrated in the drawing is used to carry out this process used. The disks B and B ¹ , which carry the bobbins χ , rotate at the same speed, but in the opposite direction. There is only a single transport roller C on that side of the machine where the finished continuous whalebone band emerges. The effect of this transport roller on the whalebone BEZW. the strip to be united is secured by a roller y. The latter is pressed against the transport roller by an internal spring. The spring tension can be regulated by means of screw D. The feed device E, through which the strips get into the machine one after the other, consists of two jaws which are placed elastically against each other by the spring F. Above these jaws lies the horizontal bridge G, which can be adjusted vertically according to the width of the whalebone. On the exit side, the plate J carries a guide over which a bridge K , which can also be regulated like G , is arranged. A curved tube L made of glass or metal is rotatably mounted on the pin M by means of hooks, and the end O of this tube can be brought closer to the incoming whalebone by means of the regulating screw N as required. The pipe end O is closed with a permeable plug made of sponge, hair or the like, while the other pipe end ν is connected by a rubber pipe to a container, which contains the liquid warm glue or other suitable adhesive, the whalebone to be glued through the pipe L and the permeable stopper is fed through in an appropriate amount. As a result of the described suspension method, the glue feed pipe can be easily set down. It goes without saying that the application of the glue can also be carried out in other suitable ways; but it remains a requirement that the gluing take place before the threads are wrapped around the whalebone, so that the latter is good. be impregnated with glue '. After the above, it is easy to understand the operation of the whole apparatus. If a strip is already gripped by the driver C , the strips trimmed in the manner described are inserted one after the other at G , taking care that a strip with an oblique end always comes to rest on an oblique end of the already grasped strip. The latter then pulls the incoming strip away with it, forcing it at the same time to go over the glue-releasing plug of the pipe end O, taking into account the first wrapping thread. The union is completed by wrapping the second thread, corresponding to the advancement of the united strips under the action of the driver or the transport roller C. On leaving the machine, the bar enters a channel P, which is suitably heated, around the glue, if it is necessary to dry it more quickly before the finished continuous rod is rolled onto a cylinder arranged for this purpose. Without it being necessary to make any changes to the apparatus, one can use it to fabricate continuous whalebone rods, which are made of double or consist of strips laid one on top of the other. . Pateντ claim: The arrangement of a device on the machine protected by the main patent for applying glue to the whalebone rods before the same with the sutures be wrapped in order to prevent the latter from peeling off when the rods are cut.
