摘要:
This invention relates to a method and apparatus for forming soft capsules andprovides novel processing flexibility. The apparatus includes extrusion die(130) as an alternative to spreader boxes, the use of melt-on-demandtechnology to enhance the long term stability of the film-forming materialsand a casting drum (9). Preferred embodiments provide a positive displacementpump to transport the molten film-forming material from the melt-on-demanddevice to the extrusion device (130) and preferably a reservoir means disposedbetween said extrusion device (130) and the means to melt said film-formingmaterial. The encapsulation apparatus may also include a valved injectionwedge.
