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 fibres (5), in particular synthetic fibres. 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.
L'invention concerne un procédé permettant d'assurer une mise en prise par friction améliorée, mais pouvant être aisément réglée et dégagée, entre deux surfaces de contact. Selon ce procédé, les deux surfaces de contact sont recouvertes de couches de matériaux (2, 4) ce qui, en cas de faible pression de contact entre les surfaces de contact, leur permet de se déplacer aisément l'une par rapport à l'autre. Toutefois, en cas de pression de contact plus forte, ces couches se mettent en prise de telle sorte que pratiquement tout déplacement entre ces surfaces de contact est impossible. Ce système peut être réalisé au moyen de deux surfaces de contact recouvertes d'une couche de fibres courtes (5), en particulier de fibres synthétiques. L'invention traite également d'un système permettant d'assurer une mise en prise par friction améliorée entre deux surfaces de contact et entre des objets recouverts de surfaces de contact de ce type.
