As shown, the rectangular platen 26 has a ?at upper surface 28 and depending side walls 29 (Figure 2) that de?ne the periphery thereof. To enable the support and feeding of the edi ble slabs of plastic material, a feed and support ing member 3%] is shaped to serve as a comple ment for the platen 26 to cooperate therewith. To this end, the feed and supporting member 30 has a ?at upper surface 31 sized to slide over and confront. the corresponding surface 28 of the platen 25, the former having front and side de pending flanges 32 to correspond with the ?anged periphery 29 of the platen 26. The slab feed and supporting member 30, in this instance, has a pair of spaced rods 33 anchored in the forward de pending flange 35!
