Abstract
Apparatus by which moulded articles are manufactured from clay, a continuously produced strand of the material in question is sprinkled with sand, whereafter at one location a piece is severed from the end of the strand at regular intervals, by a cutting apparatus, which piece then enters a mould. In the course of all phases of the process the strand and each severed piece thereof remain directed along one vertical downwardly directed line of movement.
Claims6
An apparatus for making molded articles comprising:
- a. means for continuously producing a vertical strand of plastic material, the strand moving continuously along a vertical path,
- b. means vertically beneath said strand-producing means for severing the strand at regular intervals to produce a succession of individual pieces of plastic material,
- c. a mold vertically beneath said strand-severing means, and
- d. means vertically beneath said strand-severing means and vertically above said mold for receiving each individual piece and for throwing each piece along the vertical path into said mold with sufficient kinetic energy that the piece plastically deforms and fills the mold.
