Disclosed is a rotary apparatus (2) suitable for processing and working a web or sheet of materials (6) such as plastic films, non-woven substrates, metal foils, paper, diaper cores and the like. Such apparatus includes counter- rotating anvil and tool rolls (5) through which the web or sheet of material (6) to be worked is fed. The tool roll (5) includes at least one processing tool (25) for working the web or sheet of material (6). The force of the tool (25) on the web or sheet (6) being worked is regulated by means of a force applied to the processing tool (25) or the anvil surface (36) of the anvil roll by a force-transmitting chamber (30) which includes a fluid. The force applied is adjusted by altering the pressure of the fluid within the force- transmitting chamber (30).
Cette invention se rapporte à un appareil rotatif (2) conçu pour traiter ou usiner des bandes ou des feuilles de matériaux (6) tels que films plastiques, substrats non tissés, feuilles métalliques, papier, âmes de couches jetables et similaires. Un tel appareil comprend des cylindres enclume et outil contre-rotatifs, entre lesquels passe la bande continue ou la feuille de matériau (6) à usiner. Le cylindre outil (5) comporte au moins un outil de traitement (25) servant à usiner la bande continue ou la feuille de matériau. La force qu'exerce l'outil (25) sur la bande continue ou la feuille (6) à usiner est régulée au moyen d'une force appliquée à l'outil de traitement (25) ou à la surface (36) du cylindre enclume par une chambre de transmission de force (30), laquelle contient un fluide. La force ainsi appliquée est réglée par variation de la pression du fluide à l'intérieur de la chambre de transmission de force (30).
