An adhesive coated flexible core (10) is fed to an extruder which extrudes a low density, closed cell foam sheath (14) about the core. The core and sheath composite is then cut into rod-like elements (16) of predetermined length. Each of the rod-like elements is then restrained at a position spaced inwardly from one of its ends, and an orificed plate (20) and an element end are axially pressed together such that the core extends through the orifice (22) in the plate and the foam sheath is compressed. The excess core extending through the plate orifice is then cut, and the pressure between the plate and the element is released, such that the foam sheath returns to its original condition, thereby producing a composite in which the core end is recessed into the foam sheath end. The end of the element is finished by sealing, preferably through the application of a hot brand (30).

L'invention concerne une âme (10) flexible revêtue d'adhésif, acheminée dans une machine à extruder qui extrude une gaine (14) en mousse à alvéoles fermées de faible densité autour de l'âme. Le composite âme et gaine est ensuite découpé en éléments cylindriques (16) de longueur prédéterminée. Chaque élément cylindrique est immobilisé à une position distante vers l'intérieur d'une de ses extrémités et une plaque (20) perforée et une extrémité d'élément sont pressées axialement et conjointement de façon à ce que l'âme se prolonge à travers l'orifice (22) pratiqué dans la plaque et la gaine en mousse est alors comprimée. La partie d'âme dépassant de l'orifice de la plaque est coupée et la pression entre la plaque et l'élément est relâchée, de façon à ce que la gaine en mousse retrouve son état d'origine, ce qui produit un composite. L'extrémité de l'âme est évidée dans la gaine en mousse. L'extrémité dudit élément est finalement soudée, de préférence par l'application d'une marque à chaud (30).
