Title (EN) MOULDING PLASTICS ARTICLES
(FR) ARTICLE EN PLASTIQUE DE MOULAGE
Abstract: front page image
(EN)A plastics article to be moulded has portions such as to obstruct mould release. The use of complex moulding apparatus is avoided by moulding the article with those portions disposed in positions differing from their intended positions, connected to the article by flexible webs. After moulding, the portions are hinged to their final positions, and secured. One application of the invention is the manufacture of a camera filter holder (1), where members (8, 9) with slots (71, 72, 73; 81, 82, 83) for filters, are moulded with the slots at right-angles to the plane of the holder (as shown for member 7) and then hinged through 90 and welded at the final position (as shown for member 8).
(FR)Un article en plastique a mouler possede des portions destinees a faire obstruction au degagement du moule. On evite d'utiliser un appareil de moulage complexe en moulant l'article avec ces portions disposees dans des positions qui different des positions que l'on desire obtenir, reliees a l'article par des membrures flexibles. Apres moulage, les portions sont articulees sur leur position finale, puis fixees. Application a la fabrication d'un support (1) de filtre pour camera, ou des elements (8, 9) avec des fentes (71, 72, 73; 81, 82, 83) pour des filtres sont moules avec les fentes a angle droit par rapport au plan du support (comme cela est illustre pour l'element (7)) puis articules a 90 et soudes en position finale (comme cela est illustre pour l'element (8)).
