Elastic contact element for wrapping a sheet around a group of segments

A wrapping device for wrapping a sheet around a group of segments, the wrapping device comprising:

• a wrapping conveyor comprising a conveyor surface for receiving the group of segments;
• and
• a contact element providing a counter surface, wherein the counter surface is arranged at a distance to the conveyor surface of the wrapping conveyor, wherein the counter surface faces the conveyor surface of the wrapping conveyor, and wherein the counter surface is configured to engage the group of segments and the sheet when the group of segments is moved along the counter surface by the wrapping conveyor to cause rotation of the group of segments to wrap the group of segments with the sheet,
• wherein at least a first portion of the contact element comprises at least a first part of the counter surface and is formed by a first material being an elastic material having a shore hardness between 30 A and 70 A, and
• wherein a second portion of the contact element comprises a second part of the counter surface and has different elastic properties than the first portion of the contact element, wherein the first portion of the contact element and the second portion of the contact element are arranged to contact the group of segments at different positions.
