Abstract:
A separation unit for separating a web material along preformed lines of weakness. The separation unit has a width direction and includes a first roller having a rotational axis extending in the width direction and a web width extending in the width direction, and a second roller having a rotational axis extending parallel with the rotational axis of the first roller and a web width extending in the width direction. The second roller is positioned at a distance from the first roller. Each of the first and the second rollers is provided with a plurality of protrusion elements being spaced along the rotational axes and protruding perpendicular from the axes. Each of the protrusion elements has a maximum width in the width direction, a maximum radial extension from the rotational axes, an inner portion adjacent to the rotational axes, and an outer portion remote from the rotational axes.

Claim (Index 26):
A separation unit for separating a web material along preformed lines of weakness, said separation unit having a width direction and comprising:\n a first device having an axis extending in said width direction and a web width extending in said width direction, and a second device having an axis extending parallel with said axis of said first device and a web width extending in said width direction, said second device being positioned at a distance from said first device, said distance extending in a direction perpendicular to said width direction, wherein each of said first and said second devices is provided with a plurality of protrusion elements being spaced along said axes and protruding perpendicularly from said axes, wherein each of said protrusion elements has a maximum width in said width direction, a maximum extension from said axes, an inner portion adjacent to said axes, and an outer portion remote from said axes, wherein said outer portions of said protrusion elements on said first device are arranged in a staggered relationship with said outer portions of said protrusion elements on said second device, and wherein said outer portions of said protrusion elements on said first device are partially overlapping with said outer portions of said protrusion elements on said second device with a overlap length, thus forming an undulating passage for a web material between said devices, wherein each protrusion element has a maximum width along the width direction within the overlap length, and the sum of said maximum widths within the overlap length of all protrusion elements on one of said devices is between 5-30% of said web width of that device, wherein the separation unit is configured to automatically separate the web material along preformed line of weakness via passage through the separation unit.
