ABSTRACT:
A frame supports a hollow housing which mounts thereon a hot wire die support plate from the outer side of which projects a hot wire die. The housing is pivoted to the frame for movement between an operative position in which the die projects upward for cutting a cavity in a block of material that is moved over the support plate between limit-defining stop pins, and a discharge position in which the die projects downward for the gravity release of scrap material resulting from the cutting operation. The scrap material falls onto a hot wire scrap cutting grid extending across a scrap discharge opening below the housing, whereby the scrap material is reduced to small particles as it gravitates through the hot wire grid.
