   RESUME   Le   caractère distinctif de l'invention consiste à permettre la coupe de papier,carton et matériau légers sans limitation de vitesse,d'une façon parfaite et sans devoir plus jamais affûter les couteaux constituant la cisaille de ce modèle nouveau. 

**ATTENTION** fin du champ DESC peut contenir debut de CLMS **. 



   L'appareil consiste en une cisaille à mouvement rotatif, servant à la découpe en feuilles libres,de bobines de papier, cartons et métaux légers. 



   DESCRIPTION   GENERALE   
L'appareil permet la découpe en feuilles à partir d'une bande continue à une vitesse qui n'est limitée que par les possibilités de manutention,autant à l'engagement des bobines qu'à la réception des feuilles découpées. 



   La largeur des feuilles peut aller jusque 4 mètres et plus,dépendant de la structure des matériaux utilisés,tandis que leur longueur peut varier à l'infini par le simple change- ment d'un engrenage de commande qui se place entre les cylin- dres d'acheminement et le couteau-cisaille. 



   Les tranchants ne peuvent pas s'émousser,et les cout.eaux ne doivent plus jamais être   aiguisés.Un   dispositif spécial don ne une accélération,au moment précis de la coupe,la rendant ainsi parfaite, 
NOTICE DESCRIPTIVE 
L'appareil se compose en ordre principal,de deux axes ro- tatifs A & B tournant en sens opposés et à la même vitesse,au moyen de roues dentées E. 



   Des pivots montés sur les dits axes,portent respective- ment le couteau inférieur D et le couteau supérieur C.Le cou- teau inférieur D est linéairement droit,tandis que le couteau supérieur,comme indiqué sur le plan,est construit de manière à ce que l'attaque de la coupe se fasse par les côtés.



  



   SUMMARY The distinctive character of the invention consists in allowing the cutting of paper, cardboard and light material without speed limitation, in a perfect way and without ever having to sharpen the knives constituting the shears of this new model.

** ATTENTION ** end of DESC field can contain start of CLMS **.



   The device consists of a rotary shear, used for cutting loose sheets, reels of paper, cardboard and light metals.



   GENERAL DESCRIPTION
The apparatus allows cutting into sheets from a continuous strip at a speed which is limited only by the handling possibilities, both for the engagement of the reels and for the reception of the cut sheets.



   The width of the sheets can go up to 4 meters and more, depending on the structure of the materials used, while their length can vary infinitely by the simple change of a control gear which is placed between the cylinders. conveyor and the knife-shears.



   The cutting edges cannot become dull, and the knives never have to be sharpened again. A special device does not accelerate, at the precise moment of the cut, thus making it perfect,
DESCRIPTIVE NOTICE
The device consists in main order, of two rotary axes A & B rotating in opposite directions and at the same speed, by means of toothed wheels E.



   Pivots mounted on said axles carry the lower knife D and the upper knife respectively C. The lower knife D is linearly straight, while the upper knife, as shown on the plan, is constructed in such a way. that the cut is attacked from the sides.

Claims

A hinge carries the upper knife 0 and maintains it in a fixed position by means of a pressure spring provided with specially shaped fins, which act in such a way that in case the synchronous movement of the knife is not 100% perfect , the upper knife would automatically adjust to the lower knife, thus preventing deterioration.

The cut of the lower knife D is strictly straight while the cut R of the upper knife is slightly curved, so the edge of the lower knife exactly follows the drag of the upper knife, so that there is no break in the continuity. chopped off.

The material to be cut is conveyed via P. The axles are actuated by means of toothed wheels and a chain. L is actuated by the interchangeable toothed wheel which controls the length of the sheets to be cut.

The toothed wheel L controls the toothed wheel F and, consequently, the lower axis A which, by the action of the toothed wheel, operates a number of equal revolutions, but in the opposite direction, The chain is stretched by the tendurH, To make the cut perfect, a special device gives acceleration at the precise moment of the cut, this by means of the eccentric toothed wheel F and the cam K, placed on the toothed wheel L, as well as the mounted flywheel M. on a lever N, provided with a toothed wheel.The roller M is moved apart by the cam and moves through the toothed wheel N, the chain which acts on the toothed wheel F, thus giving it acceleration at the precise moment of the cut.To this end, the cam K, is of appropriate form, Everything is assembled in a frame and equipped with ball or needle bearings.
