Segmented and laminated steel core plates (') having at least one groove or channel formed at the interface of the core plates for either double sided or single sided wet clutch friction plates or separator plates and a process for making the same are disclosed.

Segmented and laminated core steel plate for single and/or double sided wet clutch friction plates or separator plates

The present invention relates to a segmented support plate () for a lamella, which support plate () is assembled from at least two segments () in the manner of a jigsaw puzzle so as to form a boundary line () between the segments (), wherein the one segment () has a projection () which is inserted into a recess () in the other segment () so as to form a boundary line section () between the projection () and the recess (), and the projection () and the recess () are shaped such that the adjacent segments () engage behind one another, in relation to the circumferential direction () of the support plate (), in at least one first and one second partial section () of the boundary line section (). According to the invention, the projection (a) of the first partial section () onto a radial line () in the circumferential direction () at least partially intersects the projection (b) of the second partial section () onto the radial line () in the circumferential direction (). The present invention also relates to a lamella, in particular a friction lamella for a multiplate clutch, having a segmented support plate () of said type.
