Zusammenfassung:The present invention pertains to the field of the machine-tools used in the chemical industry. This invention can essentially be used in the production of tubes, or other hollow articles with an extended length, which have a small or a large section and which are made of reinforced plastic or other materials. This invention involves impregnating a fibrous filler with a binder, winding said filler on a forming body and solidifying the polymeric material while ensuring the continuous production of the finished article. The continuous production of the finished article from the forming body is achieved by imparting a reciprocating movement to the whole forming body or to its separate constituent members. The displacement speed in the direction opposite to the direction for producing the finished article is determined from the relation stipulating that the friction force generated during this displacement is lower than the force of inertia of the finished article exiting the device, or lower than the friction force retaining the article on a portion of the members of the forming body. This invention further involves applying towards the outer surface of the article and on the support side a rotating momentum as well as an axial force using the friction forces of the support members which are in contact with the article, wherein said members perform a forced rotation as well as a forced reciprocating movement at speeds which correspond to those imparted by the forming body. The number of members in the forming body as well as their displacement speed in the production direction and in the opposite one are determined from the relation stipulating that the forces applied from the members of the forming body and from the support members towards the article should be higher than the friction force applied from the members of the forming body in the direction opposite to the production direction of the article. Cette invention se rapporte au domaine des machines-outils utilisées dans l'industrie chimique. Cette invention peut notamment être utilisée dans la production de tubes, ou d'autres articles creux et de grande longueur, qui possèdent une grande ou une petite section et qui se composent de plastique renforcé ou d'autres matériaux. Cette invention consiste tout d'abord à imprégner une matière de charge fibreuse d'un liant, à enrouler cette matière de charge sur un corps de moulage et à laisser se solidifier le matériau polymère, ceci de manière à assurer la pr
