Abstract
A plurality of cores (9) extend through a second mould plate (2), which cores are rotatable around their axis and which are pressed into the mould plate (2) when disengaging mouldings (3) from the cores. In order to ensure that all cores (9), after the disengaging step, have been displaced to their rear position, which indicates that the mouldings (3) are disengaged, a force acts on the cores through a return plate (14) which is commom to all cores and which is able to return to its rear position only when all cores (9) can be displaced to this position.
