Patent number: 11957279Abstract: A separating unit for separating a web material includes a first shaft extending along a first longitudinal axis in the width direction and a second shaft extending along a second longitudinal axis, parallel to the first shaft. The second longitudinal axis is separated from the first longitudinal axis in a direction perpendicular to the width direction. A first protrusion element extends perpendicularly from the first shaft and is rotatable about the first longitudinal axis and a second protrusion element extends perpendicularly from the second shaft and is rotatable about the second longitudinal axis. In a use position, the first protrusion element partially overlaps the second protrusion element with a radial overlap oriented perpendicular to the first and second shafts. A contact element is biased against at least one of the first and second protrusion elements in a direction perpendicular to the first or second longitudinal axis.Type: GrantFiled: September 27, 2022Date of Patent: April 16, 2024Assignee: ESSITY HYGIENE AND HEALTH AKTIEBOLAGInventor: Bjorn Larsson
