Abstract: Apparatus is disclosed for slicing or scoring bakery products which comprises a stationary horizontal bed over which muffins or other bakery products are sequentially moved at high speed. Movement of the muffins is effected by first and second endless conveyor belts, each having a flight disposed adjacent the stationary bed and in opposition to the other. A hold down plate is suspended in overlying relation to the stationary bed, so that travel of the bakery products is bounded on the top and bottom by stationary surfaces, and on the sides by the conveyor belts. A disc cutting blade rotating at high speed projects into this travel space (in the preferred embodiment, one of the conveyor belts comprises dual belts which are spaced apart to permit projection of the blade therebetween), and the scoring or slicing function occurs as the bakery products move sequentially in slicing engagement with the rotating blade.

Abstract: A method for automatically varying the feed rate of a moving workpiece carriage in the proximity of permissible terminal positions for the carriage in a machine tool. The machine tool includes a numerical control means for controlling the position of the workpiece carriage and means for determining the position of the workpiece carriage in the machine tool. The improvement comprises storing signals corresponding to a plurality of safety positions of the workpiece carriage located within the terminal positions of the carriage in a memory device provided in the numerical control means.
