A slicing machine has a blade, a stop plate extending parallel to the blade, and a carriage adapted to hold a sliceable product against the plate and displaceable past the blade to cut a slice from the product. A large-diameter disk is rotatable about an axis substantially parallel to the blade and is formed with a spiral groove. A follower coupled to the stop plate is engaged in the groove. A drive motor rotates the disk to displace the stop plate parallel to the blade axis. A small-diameter sensor wheel is positively coupled by a nonsmooth drive element to the disk. A sensor determines the angular position and rotation of the disk and generates an actual-value output corresponding thereto. A desired-value signal corresponding to a desired slice thickness is fed to a controller connected to the sensor and to the motor to make the output equal to the desired-value signal.
