This invention relates to a method and apparatus for forming soft capsules and provides novel processing flexibility. The apparatus includes extrusion die (130) as an alternative to spreader boxes, the use of melt-on-demand technology to enhance the long term stability of the film-forming materials and a casting drum (9). Preferred embodiments provide a positive displacement pump to transport the molten film-forming material from the melt-on-demand device to the extrusion device (130) and preferably a reservoir means disposed between said extrusion device (130) and the means to melt said film-forming material. The encapsulation apparatus may also include a valved injection wedge.

L'invention concerne un procédé et un appareil permettant de former des capsules souples et d'obtenir une nouvelle flexibilité de traitement. Ledit appareil comprend des filières d'extrusion en tant qu'alternative à des boîtes de répartition, et l'utilisation de la technologie de fusion à la demande afin d'améliorer la stabilité à long terme des matières filmogènes. Dans des modes de réalisation préférés, une pompe volumétrique transporte la matière filmogène en fusion du dispositif de fusion à la demande jusqu'au dispositif d'extrusion, et un réservoir est de préférence placé entre ledit dispositif d'extrusion et ledit dispositif destiné à faire fondre la matière filmogène. L'appareil d'encapsulation peut également comprendre une cale d'injection à valve.
