Title: (DE) VORRICHTUNG UND VERFAHREN ZUR BESCHICHTUNG VON FIXIERUNGSELEMENTEN.
(EN) METHOD AND APPARATUS FOR COATING FASTENERS.
(FR) PROCEDE ET APPAREIL DE REVETEMENT D'ELEMENTS DE FIXATION.
Abstract: front page image
(EN) A method and apparatus for coating a fastener, particularly a fastener (20) with a head portion (23) and shank portion (24). The invention includes the steps of and apparatus for supporting (28A, 28B) the fasteners. The fasteners are conveyed such that the fasteners are moved through a plurality of operating stations and pass through a heating station (62, 64, 66) where the shank portions of the fasteners are heated. Subsequently, at a material applying station (70), a coating material is applied to the heated shank portions. A preferred embodiment of the method and apparatus of the present invention includes supporting the fasteners on their head portions with the shank portions projecting upward, conveying the fasteners with their shank portions projecting upward for processing, heating the shank portion to a temperature above the melting point of the applied material and applying the material to the heated shank portion to form a coating thereon.
(FR) Un procédé et un appareil servent à revêtir des éléments de fixation, notamment des éléments de fixation (20) ayant une tête (23) et une tige (24). Un appareil (28A, 28B) de support des éléments de fixation les soutient pendant des étapes du procédé. Les éléments de fixation sont transportés à travers une pluralité de postes de traitement et traversent un poste de chauffage (62, 64, 66) où leurs tiges sont chauffées. Un matériau de revêtement est appliqué par la suite sur les tiges chauffées dans un poste d'application (70). Dans un mode préférentiel de réalisation de ce procédé et de cet appareil, les éléments de fixation sont soutenus sur leur tête, leur tige s'étendant vers le haut, sont transportés, leur tige en haut, pendant le traitement, leur tige est chauffée jusqu'à une température supérieure au point de fusion du matériau appliqué et le matériau est appliqué sur la tige chauffée de façon à former une couche de revêtement sur celle-ci.
