A method for the production of suppository cells (P) is disclosed, in which two continuous tapes (B1-B2) of thermoplastic material are joined and the outline of the cells (P) is firstly made by welding; after storage and transportation in the flat, final shaping of the cells (P) is effected. The apparatus for carrying out the method comprises a mould (O1-O2) where the cells (P) are shaped by blow moulding; with the concurrent action of suction and blowing devices to keep the shells in the proper shape. This system allows storage and transportation of the semi-finished shells in the flat, which are then finally shaped at the plant where the suppositories are prepared.
