Abstract
The present invention relates to a method of controlling the movements of the squeze plates (2, 3) of a string moulding apparatus, and to an apparatus for carrying out the method. Such an apparatus generally comprises a moulding chamber (1) defined between two squeeze plates (2, 3). One of the squeeze plates (3) can be pivoted to open the moulding chamber (1). The production cycle of an apparatus of said kind comprises apart from the charging of the chamber (1) with mould material several movements of the squeeze plates (2, 3). A movement of one plate (2, 3) commences before the preceding movement of the other plate has finished. The hydraulic system of the apparatus comprises two pumps (30, 31), one pump for each actuator (10, 11) associated to one of the squeeze plates (2, 3).
