Abstract
Process by which moulded articles are maufactured 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.
Claims5
A method of making molded articles comprising the steps of:
- (a) continuously producing a vertical strand of plastic material, the strand moving continuously along a vertical path,
- (b) severing the moving strand at regular intervals to produce a succession of individual pieces of plastic material,
- (c) delivering each individual piece to a guide means arranged along said vertical path, and
- (d) operating the guide means to throw each individual piece along said vertical path into a mold with sufficient kinetic energy that the piece plastically deforms and fills the mold.
