   <EMI ID=1.1> 

  
Pour obtenir une coupe propre, les arêtes coupantes des

le plus possible, élastiquement sur le tambour tondeur.

  
Lorsque ce dernier est bombé, il est difficile de faire poser de manière satisfaisante les arêtes coupantes utilisées jusqu'ici, sur toute la longueur du tambour..

  
Conformément à l'invention, l'arête coupante est constituée par une mince bande d'acier. Celle-ci est posée par dessus le tambour tondeur, parallèlement à son axe, et elle est tendue par un ressort de manière à toucher élastiquement le tambour tondeur sur toute sa longueur. Cette bande pose utilement par un de ses bords longitudinaux qui est aiguisé, contre le tambour tondeur et , par son autre bord longitudinal , contre, une partie du boîtier. Grâce à cette construction il est possible de rendre cette bande excessivement fine, de sorte que l'appareil permet de se raser d'une manière particulièrement propre.

  
Le dessin représente schématiquement un exemple d'exéoution.



   <EMI ID = 1.1>

  
To obtain a clean cut, the cutting edges of the

as elastically as possible on the mower drum.

  
When the latter is convex, it is difficult to have the cutting edges used up to now fit satisfactorily over the entire length of the drum.

  
According to the invention, the cutting edge is formed by a thin strip of steel. This is placed over the mower drum, parallel to its axis, and it is tensioned by a spring so as to resiliently touch the mower drum over its entire length. This strip is usefully posed by one of its longitudinal edges which is sharp, against the mower drum and, by its other longitudinal edge, against a part of the housing. Thanks to this construction it is possible to make this strip excessively thin, so that the device makes it possible to shave in a particularly clean way.

  
The drawing shows schematically an example of execution.

Claims

Fig. 2 is an elevational view with the cover partially removed.

In the housing 1 is housed the electric control motor \ 2 which drives the mower drum 3 by means of any mechanism, not shown in the drawing. The steel strip _4, acting as a cutting edge, is laid

one of its ends to the pin 5 and is tensioned at the other end by a spring 6. The steel strip 4 rests by one of its longitudinal edges on the housing 1_ and, by its

Such a construction also makes it possible to replace the steel strip easily and at any time.

To increase the cutting effect, we can communicate to

the steel strip oscillating slightly lengthwise. This movement is carried out very easily by arranging for example the pin 5, to which the steel strip

perform a rotational movement, under the action of the control motor

----------- 1. Dry shaving device, characterized in that the cutting edge is made in the form of a steel strip.

2. Dry shaving device, according to 1, characterized in that the steel strip is resiliently placed over

by the fact that the steel strip rests on the one hand on the mower drum and on the other hand on the fixed housing.

4. Shaving machine at. dry, according to 1 to 3, characterized in that the tension of the steel strip is maintained by a special spring.
