Abstract: A sheet cake cutter is effective to cut a sheet cake disposed in a pan having a surrounding rim. The cutter has a frame supporting a conveyor belt for horizontal advancement and on which the sheet cake pan is concurrently advanced. On a transverse shaft mounted for rotation on the frame are preferably arranged at least a pair of cutter discs having edge notches therein. The cutter discs are disposed in registry with a predetermined space between them. The discs are set just to touch the bottom of the pan and with the edge notches spaced to interengage the rim. The cutter discs can be frictionally driven or shaft driven though a single-cycle clutch from the conveyor drive. The clutch is manually or automatically actuated to engage the drive by a pan on the conveyor and in position for interengagement of the notches and the pan rim. There is a hold-down roller disposed in the space between cutter discs and set at a height just above the sheet cake in the pan.
