The hiring concerns a behavioral fin that consists of a part of a shoe consists, however, of an extension in the form of a shovel

It goes without saying that the Schaxif el part should be relatively steep with Solcaen Schwiniinflose en, whereas the shoe part should be sufficiently soft rough, d '-. R.it it easily adapts to the ^ u des? -ΐ.

On the other hand, such a float should be two different May have colors.

The control thus concerns a tail fin that consists of one Shoe part p-e indicates that the blade part is injection-molded made of relatively stiff ... aterial based on resin and the shoe part made of relatively v / oak spray; egosseneia Gum..i or rubber-like material originates from i? t.

In practice, the self-blade part is made first and then inserted into a form for the öchuh, after which the "two ropes connected to each other at fuel temperature.

Pie Figure 1 shows a perspective view of the Schwisraxlosse formed in accordance with the inflation, seen from above. FIG. 2 shows a perspective illustration to show the underside of the selector fin according to FIG. 1.

! / he Sciiaureiteii is formed from a relatively stiff, elastic material, as it - .., Β, is known under the trade name "ULT-_A.TEilE". The shaped shovel part, as can be seen from FIGS. 3 and 4, is then placed in a mold which is used to shape the shoe part j 6. 2 The shoe part is manufactured by injection molding from synthetic rubber or rubber-like material, ^e.g. the material known from the Irma Shell under the name "NARI? L3"; lf it fuses with the end sections of the blade part.

The two materials "/ earth in the case of the one prevailing during the injection Temperature linked so that one. receives an object forming a piece.

The measure of the separate molding of the two parts allows to give the fin two different colors.

The working time required for production is considerably shorter than with known injection molding processes and much shorter than with the Yulkani si er s.
