Abstract

Appareil de formage (52) agencé pour former des articles ayant un profil incurvé, en particulier des articles incurvés avec un bord rabattu, tels que, par exemple, des garde-boue, comprenant un châssis (54) portant un premier rouleau de formage (26), au moins un rouleau de formage intermédiaire (28) monté de façon ajustable en une position entre le premier rouleau de formage (26) et un rouleau de formage final (42). Le profil incurvé de l'article à former peut être ajusté en modifiant les positions relatives desdits rouleaux. Une bande de matériau plastique (10) passe sur lesdits rouleaux et, dans le cas où un bord rabattu doit être formé, la bande (10) est de largeur (W) supérieure à celle des rouleaux (W1 ) et est étirée sur les rouleaux de façon que les bords de la bande s'inclinent radialement vers l'intérieur par rapport à la région centrale de la bande. Cette disposition permet la production d'articles incurvés ayant des rayons différents sans besoin de changer un rouleau.Forming apparatus (52) arranged to form articles having a curved profile, in particular curved articles with a turned-down edge, such as, for example, mudguards, comprising a frame (54) carrying a first forming roller ( 26), at least one intermediate forming roll (28) adjustably mounted in a position between the first forming roll (26) and a final forming roll (42). The curved profile of the article to be formed can be adjusted by changing the relative positions of said rollers. A strip of plastic material (10) passes over said rollers and, in the event that a folded edge is to be formed, the strip (10) has a width (W) greater than that of the rollers (W1) and is stretched over the rollers so that the edges of the strip slope radially inwardly relative to the central region of the strip. This arrangement allows the production of curved articles having different radii without the need to change a roll.
