Abstract

This invention relates to a method and apparatus for forming soft capsules and provides novel processing flexibility. The apparatus comprises a three-way valve injector wedge. This injector wedge allows for set-up of the encapsulation machine with a placebo fill and quick change over to active fill. This conserves use of the active ingredient.
