#CMT# #/CMT# The device has a cutting roller (9) and an impression roller (10) between which a cutting gap (14) is formed, where material web e.g. non-woven fabric, is guided via the gap. A pressure-controlling element (1a) presses the rollers against each other with adjustable force. The roller (9) lies over bearer rings (15a, 15b) at the impression roller. The force is adjustable based on values determined by a force sensor. The rings include a conical or frustum-shaped outer contour. An axial-controlling element (1c) is provided for axial adjustment of the cutting roller and/or the impression roller. #CMT# : #/CMT# An independent claim is also included for a method for rotational cutting of products of a material web by a cutting roller and an impression roller. #CMT#USE : #/CMT# Device for rotational cutting of products e.g. diaper and bandage, of a material web e.g. non-woven fabric, plastic film and textile. #CMT#ADVANTAGE : #/CMT# The arrangement of the axial-controlling element enables the adjustment of a distance between the cutting roller and the impression roller independent of the adjustment of the force by the pressure-controlling element. The device can change the distance between the rollers depending upon axial shift and/or adjustment of the rollers to each other, if the axial-controlling element adjusts one of the two rollers in an axial direction. The device achieves faster and more accurate adjustment of optimal force and/or an optimal distance between the rollers, and decreases the wear of a cutting knife during rotational cutting, by the independent and additional adjustment possibility of the distance between the rollers by the axial-controlling element. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic front view of a device for rotational cutting of products of a material web. 1a, 1b : Pressure-controlling elements 1c : Axial-controlling element 9 : Cutting roller 10 : Impression roller 14 : Cutting gap 15a, 15b : Bearer rings. |
