APPARATUS AND METHOD FOR MANUFACTURING ENCAPSULATED PRODUCTS

摘要

This invention relates to a method and apparatus for forming soft capsules a nd 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 displacemen t pump to transport the molten film-forming material from the melt-on-demand device to the extrusion device (130) and preferably a reservoir means dispos ed between said extrusion device (130) and the means to melt said film-forming material. The encapsulation apparatus may also include a valved injection wedge.
