Claim:
A method for manufacturing a multi-layer compression moulded element having at least a first moulding layer and a second moulding layer adjacent to the first mounding layer, The method comprising the steps of: providing a multi-component moulding tool having a moulding element and a moulding slide arrangement selectively displaceable within the moulding element to define at least a first moulding segment when the moulding slide arrangement is in a first position and a second moulding segment when the moulding slide arrangement is in a second position, different than the first position; providing a filling unit having a filling frame defining at least two filling chambers, the filling frame having a sliding seal; providing a moulding die which is displaceable within the moulding element; providing a moulding table on which the filling unit may slide in a direction transverse to a compression axis; selectively positioning the moulding slide arrangement to define the first moulding segment; filling the first moulding segment with moulding material from a first of the two filling chambers of the filling unit; selectively positioning the moulding slide arrangement to define the second moulding segment; sliding the filling unit in a direction transverse with respect to the axis of the moulding die so that the second of the two filling chambers of the filling unit fills the second moulding segment with moulding material; forming the compression moulded element by moving the moulding die and the moulding slide arrangement towards one another in the mould to compact the moulded element; removing the moulding die from the mould; and ejecting the compression moulded element from the mould by advancing the moulding slide arrangement.
