Title
(DE) VORRICHTUNG UND VERFAHREN ZUM STANZEN VON VERPACKUNGSELEMENTEN OD. DGL.
(EN) DEVICE AND METHOD FOR STAMPING PACKAGING ELEMENTS OR SIMILAR
(FR) DISPOSITIF ET PROCEDE DE DECOUPE D'ELEMENTS D'EMBALLAGE OU SIMILAIRES
Abstract
(DE) Bei einer Vorrichtung zum Stanzen von flächigen Verpackungselementen od. dgl. -- wie Bogen (30) aus Papier, Karton oder Wellpappe -- mit von einer Stanzform (10) abragenden Stanzmesser (14) als Form- oder Trennelement ist der auf einer Trägerstanzplatte (20) angeordnete Bogen (30) den Messerspitzen bzw. Schneiden (16) der Stanzmesser (14) zugeordnet, wobei zwischen der Oberfläche (22) der Trägerstanzplatte (20) und dem Stanzbogen (30) eine Schicht (26) aus magnetischem Werkstoff angeordnet ist, die bevorzugt aus einem elastischen magnetischen Werkstoff besteht. Zwischen dem Stanzbogen (30) und der Schicht oder Matte (26) aus magnetischem Werkstoff ist eine diese übergreifende metallische Gegenstanzplatte (24a) aus hartem Metall angeordnet. Die Gegenstanzplatte (24a) soll nahe wenigstens zweier Kanten-bereiche jeweils einem Durchbruch in der Schicht oder Matte (26) zugeordnet sein, wobei sich unter dieser Öffnung eine Einformung der Trägerstanzplatte (20) befindet, die sich von deren Oberflächen (22) weg zu einem runden Endabschnitt hin verjüngt.
(EN) The invention relates to a device for stamping flat packaging elements or similar, such as sheets (30) made from paper, cardboard or corrugated board. Said device comprises, a stamping knife (14) as a forming or separating element protruding from a stamping die (10) and the sheet (30) disposed on the carrier stamping plate (20) is associated (30) with the tip and/or blade (16) of the stamping knife (14). A layer (26) made of magnetic material is disposed between the surface (22) of the carrier stamping plate (20) and the stamping sheet (30), said layer preferably being made of an elastic magnetic material. A metal counter stamping plate (24a) made of hard metal is arranged between the stamping sheet (30) and the layer or mat (26) made of magnetic material, said metal counter stamping plate overlapping with said layer or said mat. The counter stamping plate (24a) is associated with an opening in the layer or mat (26) close to, respectively, at least two edge areas. A formation in the carrier stamping plate (20) is arranged below said opening, said formation tapering in from the surface (22) of the support stamping plate (20) to a round end section.
(FR) L'invention concerne un dispositif servant à découper des éléments d'emballage plats ou similaires, tels que des feuilles (30) en papier, carton ou carton ondulé. Ce dispositif comprend comme éléments de formage ou de découpe des emporte-pièces (14) faisant saillie par rapport à une forme de découpe (10), la feuille (30) disposée sur une plaque de découpe support (20) étant associée aux pointes ou aux tranchants (16) des emporte-pièces (14). Selon l'invention, une couche (26) de matériau magnétique est disposée entre la surface (22) de la plaque de découpe support (20) et la feuille (30) à découper, cette couche étant constituée de préférence d'un matériau magnétique élastique. Entre la feuille (30) à découper et la couche ou le mat (26) en matériau magnétique est disposée une plaque de découpe conjuguée (24a) en métal dur recouvrant ladite couche ou ledit mat. Cette plaque de découpe conjuguée (24a) doit être associée à une ouverture respective dans la couche ou le mat (26) à proximité d'au moins deux zones périphériques. Un évidement ménagé dans la plaque de découpe support (20) est situé sous ladite ouverture, cet évidement se rétrécissant de la surface (22) de la plaque de découpe support (20) à une section d'extrémité arrondie.
