Title
(EN) A CUTTING ARRANGEMENT FOR CUTTING PAPER OR SHEET WEBS
(FR) SYSTEME DESTINE A COUPER TRANSVERSALEMENT DES BANDES OU FEUILLES CONTINUES DE PAPIER
Abstract
(EN)
For the cutting of narrow paper or sheet webs in flow packaging systems, e.g. for the packing of ice-cream bodies, it is known to use a cutter bar, a cutter edge (4) of which is forced against an anvil surface (9) for throughcutting the web. In order to achieve an efficient cutting it may be required to use a relatively high cutting pressure, which will act destructively on the sharpness of the cutting edge in causing a lasting deformation thereof, whereby the lifetime of such knives is relatively short. According to the invention the tool set is made in such a manner that the cutter bar and the anvil have cooperating abutment portions (6, 9) which ensure that these parts cannot be forced together further than corresponding to a purely resilient deformation of the cutter edge (4). Thus, quite high cutting pressures can still be used, but now in a controlled manner with respect to an acceptable deformation of the cutter edge. Consequently, both a high efficiency and a good durability of the tools will be ensured.
(FR)
Dans les systèmes de conditionnement en continu, lorsque l'on coupe des bandes ou feuilles étroites et continues de papier, par exemple pour emballer des corps de crèmes glacées, on se sert généralement d'une lame de coupe dont le bord coupant (4) est poussé contre une surface d'enclume, afin de pouvoir trancher la bande. De manière à couper efficacement cette bande, il peut être nécessaire d'utiliser une pression de coupe relativement élevée, ce qui endommage le tranchant de la lame en provoquant une déformation durable de celui-ci, la durée de vie de tels couteaux étant donc relativement courte. Selon l'invention, on a réalisé un ensemble outil de manière à ce que la lame de coupe et l'enclume possèdent des portions de butée coopérantes (6, 9), lesquelles ne peuvent être forcées l'une contre l'autre au-delà de ce qui correspond à une déformation purement élastique du bord coupant (4). Ainsi, on peut encore utiliser des pressions relativement élevées de coupe, mais d'une manière régulée en fonction d'une déformation acceptable du bord coupant. De cette façon, on obtient des outils présentant une grande efficacité et une bonne durabilité.
