Description

Machine for profiling vulcanized rubber soles It is already 'known to form rubber shoes or cloth shoes with rubber soles in pressing machines and finished or only partially vulcanized.

With regard to this vulcanization in the press machine must Rubber parts are covered by the mold, so in the production of cloth shoes with rubber umbels at least also laterally movable molded parts to hold the Sole be present.

In contrast to this production of rubber shoes by compression molding when the shoe is hand-made, the shoe is already finished before the sole is applied Ready-made, so that a single press die is sufficient to press on the sole. With this type of production, the soleplate has already been rolled out so far profiled and therefore had to for the different types and sizes of shoes. one Keep a lot of profiled soles in stock. According to the invention, this is now Profiling only made at the same time as pressing the sole onto the already ready-made shoe. Since no vulcanization is required here, it is sufficient to press on with a single press ram in a machine without a lateral Molded parts. There are therefore only smooth calendered soles for all types of soles Rubber plates and rubber soles punched out of them are necessary.

An embodiment of the machine according to the invention is shown in FIGS Drawings shown, namely Figures i and 2, show a side and front view of the machine, Fig. 3 the actual sole stamp in plan view, Fig. ¢ and 5 sections according to the line A-B or C-D in Fig.3.

The machine frame carries a table over which the strips are attached hike continuously with the finished, but vulcanized shoes that have been pinched on. The upwardly extending part of the machine is a stand a, the is pierced in its upper horizontally elongated part to provide a support b to record. This carrier can be driven horizontally by a Zahnstangena Direction- move back and forth. At the front end of this beam is a guide d, a lever holder c is attached to the rear end. In the guide d can be through a Lever a stamp holder e can be moved up and down. At the end of this stamp holder Finally, the actual sole stamp e1f is attached so as to be removable and replaceable.

On the upper part of the sole stamp, in which there is an electrical resistance heater g, a differently engraved lower part can be attached as desired. The curvature of the lower part is adapted to the shape of the last of the shoe to be covered.

The semi-arcuate engraving means that the Guaranteed sole edge and at the same time achieved a bevel of the same. Instead of a somehow engraved sole calender roller, there is only one corresponding engraved lower part of the stamp required.

The mode of operation of this machine is as follows: depending on the size of the shoe to be covered with the sole to be profiled is the carrier b with shifted the whole stamp mechanism in the horizontal direction, in each case as far forwards or backwards as the position of the soles of the lasts, all of which are without Considering their size, they are attached to the two pins in the same place, requires. The sole stamp used as required is now in a @ warmed state moved down by the lever and pressed onto the sole. This pressing banishes possibly also done hydraulically or by an eccentric. Through the on the soft = pressure exerted on vulcanized rubber sole, the sole is profiled in one simple operation.
