Abstract
In a massaging apparatus (1) with two rotatable rollers (14, 15), which are spaced apart transversely to their roller axes (16, 17), at least one of the rollers being rotationally drivable by a roller drive motor (25), and with a suction chamber (39) disposed in the area of the two rollers (14, 15) and communicating with a pump (50) via an air-transfer line (49) for generating a vacuum in the suction chamber (39) so as to form a skin fold (57) which is drawn into the suction chamber (39), there has been provided a control device (80), preferably formed by an electropneumatic vacuum switch, which is responsive to a partial vacuum and which communicates with the suction chamber (39), the roller drive motor (25) being adapted to be turned on under control of the control device (80) when a given vacuum is reached in the suction chamber (39).
