Claims

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 groups of segments;
a contact element providing an opposing surface, said opposing surface being disposed at a distance from said conveyor surface of said wrapping conveyor, said opposing surface facing said conveyor surface of said wrapping conveyor, and said opposing surface facing said conveyor surface of said wrapping conveyor; the opposing surface engages the group of segments and the sheet to cause rotation of the group of segments and wrap the group of segments with the sheet as the group of segments is moved along the opposing surface by the wrapping conveyor; a contact element, the opposing surface being configured to
at least a first portion of the contact element comprising at least a first portion of the opposing surface is formed of a first material that is a resilient material having a Shore hardness of 30A to 70A, and a second portion of the contact element a portion comprising a second portion of the opposing surface and having different elastic properties than the first portion of the contact element, the first portion of the contact element and the second portion of the contact element; A wrapping device arranged to contact said group of segments at different locations.

The wrapping apparatus of claim 1, wherein the first material has a Shore hardness of 40A to 50A.

Wrapping according to claim 1 or claim 2, wherein the first material has a Young's modulus of elasticity of less than 20 MPa, or less than 15 MPa, or less than 10 MPa, or less than 5 MPa, or less than 3 MPa, or less than 2.5 MPa. Device.

According to any one of claims 1 to 3, the first part of the contact element has a thickness of at least 1 mm, or at least 2 mm, or at least 4 mm, or at least 6 mm, or at least 8 mm, or at least 10 mm. The wrapping device described.

Wrapping device according to any of claims 1 to 4, wherein the first part of the contact element and the second part of the contact element have different thicknesses.

A wrapping device according to any of the preceding claims, wherein the second part of the contact element is formed by a second material having a Shore hardness of at most 100A, or at most 90A.

Any one of claims 1 to 6, wherein the conveyor surface defines a groove for receiving the group of segments, the groove being oriented at right angles to the direction of conveyance of the group of segments. The wrapping device described in Section.

A system for manufacturing smoking articles, the system comprising:
a wrapping device for wrapping a sheet around a group of segments according to any one of claims 1 to 7;
the sheet;
a group of segments comprising a segment of a smoking article.

The segment of the smoking article is one of a segment comprising a heat source for the smoking article, a segment comprising tobacco material, a segment comprising a filter for the smoking article, and a segment comprising a mouthpiece for the smoking article. 9. The system of claim 8, comprising:

A method of wrapping a sheet around a group of segments, the method comprising:
driving a wrapping conveyor to convey the group of segments on a conveyor surface of the wrapping conveyor and causing them to run along opposing surfaces of contact elements facing the conveyor surface;
the group of segments engages the opposing surfaces and is thereby rotated, thereby wrapping the group of segments with the sheet;
The method wherein at least a rigid segment of the group of segments elastically deforms the opposing surface away from the conveyor surface, the rigid segment comprising a heat source.

11. The method of claim 10, wherein the rigid segment comprises an uncuttable object.

the group of segments includes, in addition to the rigid segment, one or more of a segment comprising tobacco material, a segment comprising a filter for a smoking article, and a segment comprising a mouthpiece for a smoking article; The method according to claim 10 or claim 11.

The method according to any one of claims 10 to 12, wherein the elasticity of the opposing surface is different for different regions of the opposing surface.

the deformation of the opposing surface by the rigid segment is such that the distance between at least a portion of the deformed section of the opposing surface and the conveyor surface is such that the deformation of the opposing surface is due to the deformation of the opposing surface; 14. A method according to any one of claims 10 to 13, wherein the method is increased by at least 0.1 mm, or by at least 0.3 mm, or by at least 0.5 mm, or by at least 0.7 mm, or by at least 1 mm.

preferably having at least a first portion made of an elastic material having a Shore hardness of 30A to 70A as an opposing surface for wrapping the group of segments into a sheet of wrapping material to produce a smoking article. Use of a contact element, wherein the elasticity of said opposing surface is different for different regions of said opposing surface.
