described injection molding process this variant features instead of the above described lateral running fixing areas a multiplicity of fixing points 200 in which respectively the tool impinges for fixation during the manufacturing process fig2 c illustrates second basic variants of a two sided seal with which a lip geometry is provided the embodiment of the seal here shown possesses two seal lips 110 on each side of the support 100 so that as a result a double lip is obtained herewith the fixation also results by means of fixing points 200 a combination of the first and second variants is possible fig2 d to 2 f show possible variations of separator or limiter which can be used in seals in accordance with the invention the variations of the separator are displayed by reference to the embodiments illustrated in fig2 c but can also be used in combination with the first variant according to fig2 a or respectively in another connection containing mixed variants of first and second variants in fig2 d a separator is first of all realized by means of a stamped support a stamping of this kind can result by embossing of channels especially half channels in the support furthermore in fig2 e a separator is realized by means of a folded on both sides area of the support so that a separator with a height equal to the multiple folding plus one support thickness is obtained in conclusion in fig2 f a separator is realized by means of a one sided support folding in a predetermined support area the separator is averaged that is the separator is arranged.
