Title (EN) APPARATUS FOR CONSTANT PRESSURE IN LINE-WEB CRUSH-SCORING
(FR) APPAREIL D'APPLICATION D'UNE PRESSION CONSTANTE DANS UNE OPERATION D'ENTAILLAGE PAR ECRASEMENT D'UNE BANDE DE SUPPORT
Abstract:
(EN) Apparatus for applying constant pressure to a plurality of anvil rollers (12) for crush-scoring used in combination with crush-scoring cylinders (68) having protrusions (88) extending from the surface thereof. Each anvil roller (12) is supported in a substantially frictionless manner and the constant pressure is supplied by a flexible diaphragm (60) acting on a plunger (56) which can move substantially without friction in a pneumatic cylinder (52).
(FR) Appareil d'application d'une pression constante à une pluralité de rouleaux-enclumes (12) pour l'entaillage par écrasement, lesquels rouleaux sont utilisés en combinaison avec des cylindres d'entaillage par écrasement (68) ayant des protubérances (88) s'étendant depuis leur surface. Chaque rouleau-enclume (12) est supporté sensiblement sans friction et la pression constante est fournie par un diaphragme flexible (60) agissant sur un piston (56) qui peut se déplacer sensiblement sans friction dans un cylindre pneumatique (52).
