A cloth-spreading apparatus having an improved control for controlling the movement of a carriage assembly across an elongated table. The control includes one or more sensors in the form of photoelectric eyes (52-58) which are capable of sensing a light-reflective medium (60, 76) and nonreflective surfaces (72, 74 or 78), which sensed positions are processed by a controller (50) to cause an electric motor (42) to be slowed down when the carriage assembly (24) reaches a slowdown position and to be stopped or reversed when a stop position is attained. The sensors are in an "on" state when the carriage assembly is moving and in an "off" state when the carriage assembly is not moving.
