1. A dough imprinting device for use in combination with a conveyor means for imprinting characters onto dough pieces being transported by said conveyor means, said dough pieces being arranged in lines of a plurality of dough pieces substantially parallel to the direction of movement of said conveyor means and said dough pieces being spaced apart in direction along said lines, said device including separate sensor means for each line of dough pieces on the conveyor means sensing the position of each of the dough pieces in each of the lines and providing a signal indicating a known position of each dough piece in each line, and a separate imprinter device for each line of dough pieces, each imprinter device comprising a rotating block member carrying individual indicia to be imprinted at a plurality of annularly spaced locations at the outer edge thereof, each block member clearing said dough pieces except at the location of said indicia thereon, means to rotationally mount and frictionally drive each block member about a central axis, separate means to restrain rotational movement of each block member at a plurality of rotational positions each of which is a position with the block member clearing dough pieces on the conveyor means, said separate means to restrain being movable to a position to permit rotational movement of its associated block member, and control means responsive to receipt of said signal from the respective corresponding sensor means to move each means to restrain to position to permit its associated block member to rotate only sufficiently far for one of said indicia to imprint a dough piece sensed by the sensor means for that block member subsequent to receiving a signal from the respective sensor means and to release said means to restrain to return it to position restraining said block member prior to the time second indicia on the associated block member moves to an imprinting position.
