ABSTRACT:
Apparatus for manufacturing articles is disclosed in which a preheated sheet of thermoplastic material is intermittently fed to present successive preheated portions of the sheet in a work station having a forming tool for forming articles in each successive sheet portion and a stamping tool for co-operating with the forming tool to stamp the formed articles from the sheet. The forming tool has a plurality of forming dies which are movable successively and cyclically into the work station for forming articles in respective successive sheet portions. After each forming operation the stamping tool is brought into engagement with a resilient counter-surface on the forming die to stamp from the sheet the articles formed by that die.
