Abstract

The cutting tool for cutting a plastic film (3) on a metal support plate (4), operates by use of a heated blade to cut through the plastic by fusion. The tool may be flat or rotary, and carries cutting blades which may be either continuous or separated. The blades are heated either by means of hot circulating oil or by electrical resistance heating elements. In alternative designs, the blades may be heated by hot air or by magnetic induction heating.

Description

DISPOSITIF POUR COUPER A MI-CHAIR
DES MATERIAUX COMPOSITES
La présente invention concerne un dispositif pour découper à mi-chair, à plat ou en rotatif, un complexe coposé d'une feuille de métal mince associée à une couche de film plastique, sans altérer de manière significative, et sans blesser le support en métal mince.DEVICE FOR CUTTING HALF-FLESH
COMPOSITE MATERIALS
The present invention relates to a device for cutting half-flesh, flat or rotary, a coposed complex of a thin metal sheet associated with a layer of plastic film, without significantly altering, and without injuring the metal support slim.

Cette opération est traditionnellement réalisée par un outil coupant et une contrepartie dure.This operation is traditionally carried out by a cutting tool and a hard counterpart.

Dans le cas spécifique d'un film plastique à découper, son élasticité accompagne l'outil dans l'opération de découpe, et la coeiséquence en est la blessure ou la découpe du support métal.In the specific case of a plastic film to be cut, its elasticity accompanies the tool in the cutting operation, and the co-sequence is the injury or cutting of the metal support.

L objet de l'invention est de remeuier à cet inconvénient.The object of the invention is to overcome this drawback.

I1 colporte, en effet, un outil à plat ou cylindrique (1) dont les filets de coupe continus ou discontinus (2), sont portés à une température réglable en fonction de la matière à découper. La température est obtenue par fluide thermique ou résistance électrique ou air chaud, ou induction magnétique. I1 peddles, in fact, a flat or cylindrical tool (1) whose continuous or discontinuous cutting threads (2) are brought to a temperature adjustable according to the material to be cut. The temperature is obtained by thermal fluid or electrical resistance or hot air, or magnetic induction.

La température provoque un ramollissement du film plastique (3) avec disparition de 1' élasticité, permettant ainsi une découpe par pseudo-fusion sans blesser le support (4). The temperature causes a softening of the plastic film (3) with disappearance of the elasticity, thus allowing cutting by pseudo-fusion without injuring the support (4).
