ABSTRACT:
Method for obtaining an improved but easily adjustable and releasable frictional engagement between two contact surfaces. According to the method, both contact surfaces are provided with material layers (2, 4) which, when there is low contact pressure between the contact surfaces, ensure that these surfaces are able to move comparatively easily in relation to each other, but, when there is higher contact pressure, these material layers engage in each other and make relative movement between the contact surfaces impossible or substantially difficult. This can be achieved by means of both contact surfaces being flocked with a layer of short fibers (5), in particular synthetic fibers. The invention also relates to an arrangement for obtaining an improved frictional engagement between two contact surfaces and to objects provided with such contact surfaces.
