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