ABSTRACT:
A rounded edge portion of a core of a composite plate is cut away after a laminate has been bonded to the upper surface thereof so that the rounded edge portion can be tilted upwardly. The groove which extends upwardly from a lower portion of the edge is spread in a wedge manner and is filled with a durable filling before the laminate is bent over the edge portion and bonded thereby to simultaneously close the mouth of the groove.
