Title
(EN) MANUFACTURE OF MOULDED PLASTICS ARTICLES HAVING INCORPORATED BLANKS
(FR) FABRICATION D'ARTICLES EN PLASTIQUE MOULES A ELEMENTS DECOUPES INCORPORES
Abstract
(EN)
Moulded plastics articles have blanks of sheet material, e.g. as labels and/or diffusion barriers, incorporated into them during moulding, a plurality of the articles being moulded in each moulding operation. At least sufficient blanks are cut at a time for each moulding operation. The blanks, preferably of a flimsy plastics film material, are positively held discretely from when they are cut until they are positioned for location in the mould cavities. As cut by dies (A, B, C, D), the blanks may be at different spacings from the mould cavities (4), their spacing then being adjusted to suit the cavities as they are held after cutting and/or collected for transfer to the mould. Alternatively, a group of blanks (Y, Y1, Z, Z1) may be cut in which the number of blanks is a multiple of the number of mould cavities (4) and there are sets of blanks in the group each having blanks of corresponding spacing and configuration to the mould cavities. The sets are transferred in turn to the mould for successive moulding operations.
(FR)
Articles en plastique moulés auxquels on incorpore, lors de leur moulage, des éléments découpés dans un matériau en feuille, par exemple des étiquettes et/ou des barrières de diffusion, une pluralité de ces articles étant moulée dans chaque opération de moulage. On coupe en une fois une quantité au moins suffisante d'éléments pour chaque opération de moulage. Ces éléments découpés sont de préférence composés d'un film plastique léger, et ils sont maintenus séparément les uns des autres lorsqu'ils sont coupés jusqu'à ce qu'ils soient prêts à être placés dans les cavités du moule. Etant donné que ces éléments sont coupés par des matrices (A, B, C, D), ils peuvent se situer à des espacements différents de ceux des cavités (4) du moule, leur espacement étant alors réglé pour s'adapter à celui des cavités au moment où ils sont maintenus après avoir été coupés et/ou rassemblés pour être transférés dans le moule. Dans un autre mode de réalisation, un groupe d'éléments découpés (Y, Y1, Z, Z1) peut être coupé en un nombre qui est un multiple de celui du nombre des cavités (4) du moule, et il y a des ensembles d'éléments dans le groupe, chaque ensemble possédant des éléments dotés de l'espacement et de la configuration correspondant aux cavités du moule. Ces ensembles sont transférés à leur tour dans le moule aux fins de réalisation des opérations successives de moulage.
