摘要： A method for making the shaving head of a dry-shaving apparatus with an effective shaving area of a desired shape, in which a shear foil is mounted in an arcuate condition in a shaving-head frame without the cutter so that the foil assumes a free clamping curvature which is not influenced by the cutter, a normal-pressure distribution is applied perpendicular to the foil curvature which simulates the pressure distribution between the cutter and the foil in conformity with a desired effective shaving area, so that the shear foil experiences in said effective shaving area a deformation relative to the free clamping curvature, the simulated pretension curvature thus obtained corresponding to the desired normal-pressure distribution on the cutter in the desired effective shaving area relative to the shear foil.The cutting edges of the cutter are curved in conformity with the pretension curvature of the shear foil thus determined and the cutter, whose shape is in conformity with said pretension curvature, is pressed into the shear foil with the force which provides the desired normal-pressure distribution.

摘要： A drive mechanism for a domestic vibration-type apparatus is provided, in which the rotor shaft (19) of a single-phase synchronous motor drives a cam-and-follower mechanism which converts the rotary motion of the rotor into a vibratory motion, the rotor and the stator having a main field direction (22) and (16), respectively. The longitudinal axis of the mirror-symmetrical cam extends at an angle to the main field direction (22) of the rotor. Rollers (31, 31a) which follow the cam (21) are arranged on a pivotal arm which is pivot about its central portion and a vibratory part (39) to be driven is arranged on the driving end (35) of this pivotal arm. As they cooperate with the cam the rollers are constantly in contact with the cam profile. At the end of the transmission path, which exhibits backlash, vibratory part (39) cooperates with a spring (38) which urges one of the rollers against the cam, causing the position of the cam relative to the direction of magnetization of the rotor to be changed so that the rotor is forced out of a position in which the direction of magnetization of the rotor and the main field direction of the rotor extend parallel to each other, by means of the spring (38), preferably in the positive direction. In this parallel position the vibratory part (39) is situated near of its reversal point. To obtain a further noise reduction a unidirectional blocking device is included.

摘要： In a dry-shaving apparatus which is adapted to be connected to an a.c. source and which comprises at least one reciprocating cutter, there is provided a self-starting single-phase synchronous motor for driving the cutter. Via at least one drive mechanism, which couples the drive spindle of the motor to the cutter and which converts the rotary movement of the drive spindle into a reciprocating movement of the cutter, the cutter is made to occupy substantially one of the two extreme positions in its reciprocating movement in those positions of the rotor of the motor in which the driving torque has zero value.
