Abstract

The invention relates to a device for cutting out material in a rotary continuous without any apparent joins. The device for cutting out a strip of material is used to obtain an extremely long line (stencil), comprising open-worked, continuous and repetitive parts without any apparent joint, characterized in that it consists of a continuous rotary tool (1) which cuts out the material with the aid of steel blades (6) which are surrounded by repulsive strips (7) which are crimped in the grooves (9) of the segments (5) which themselves are fixed to a cylinder (4) maintained by flanges (3) forming a body with the cylinder and the shaft (2) used to drive the unit.

Thanks to this process, the tool will always be under pressure and in contact with the material and the cylindrical block, the assembly being in permanent rotation, cutting the material continuously.

Généralement lorsque l'on découpe de la matière dans un panneau ou en rouleau, c'est pour en extraire des pièces individuelles et mettre au rebut (à la poubelle) la partie évidée restante, dans notre cas c'est l'inverse, les parties individuelles partent à la poubelle et la partie restante forme la trame (le pochoir)Generally when cutting material from a panel or roll, it is to extract individual parts and discard (in the trash) the remaining hollowed out part, in our case it is the reverse, individual parts go to the trash can and the remaining part forms the frame (the stencil)

Le dispositif présenté propose sans aucune comparaison avec les méthodes actuelles, une façon simple de découper de la matière provenant d'une bobine, sans que l'on puisse voir dans cette matière découpée sur une grande longueur un début ou une fin de découpe Ce dispositif apporte de nombreux avantages à savoir entre autres - Permet de découper de la trame sur de très grandes longueurs d'un seul tenant - Permet une découpe sans raccord visible - Facilite la découpe sans difficulté de pièces individuelles ou complexes - Peπnet d'avoir une cadence de production très élevée - Utilise les diamètres d'outils existants - Peut être utilisé en modifiant certaines machines actuelles Le dispositif selon l'invention permet de découper tout type de pièces de dimension n'excédant pas la laize de l'outil et n'excédant pas dans le motif a découper la circonférence de l'outilThe device presented offers without any comparison with current methods, a simple way to cut material from a coil, without it being possible to see in this material cut over a great length a beginning or an end of cutting. This device brings many advantages, namely among others - Allows you to cut the weft over very long lengths in one piece - Allows a cut without visible connection - Facilitates the cutting without difficulty of individual or complex parts - Peπnet to have a rate of very high production - Uses the diameters of existing tools - Can be used by modifying certain current machines The device according to the invention makes it possible to cut any type of pieces of dimension not exceeding the width of the tool and not exceeding not in the pattern is cut the circumference of the tool
