Problems solved by technology

[0005] Presently, state-of-the-art machines and methods are not able to meet the specified tolerances because they are subject to errors in the positioning and / or alignment of the individual layers of the multilayer web and due to, for example, tension variations in the feed of the continuous web. The phase shift between the processing stations

Embodiment Construction

[0028] With reference to the drawings, reference numeral 1 denotes a multilayer cylindrical tubular rod from which a rod section suitable for manufacturing a substantially cylindrical smoker's article is obtained.

[0029] The rod 1 and the rod segments not shown comprise a first layer 2 of a first material. The first layer 2 is spliced ​​longitudinally to form the first splicing portion 3 of the corresponding side edge 4 of the first layer 2.

[0030] The rod 1 and therefore the not-shown rod segment comprises a second layer 5 of a second material. The second layer 5 is spliced ​​longitudinally to form the second splicing portion 6 of the corresponding side edge 7 of the second layer 5.

[0031] The first layer 2 occupies a radially inner position relative to the second layer 5 in both the rod section and the rod 1

[0032] The second layer 5 is continuous along the main extension direction "X" of the rod 1, which is consistent with the feeding direction of the rod during the produc...

Abstract

A machine (100) for making pieces of a multilayer, cylindrical tubular rod (1) suitable for making substantially cylindrical smokers' articles comprises first means (101) for feeding at least a firstcontinuous web (102), second means (103) for feeding a second continuous web (104), means (107) for forming a continuous, multilayer web (M) by superposing at least a first layer (2) and a second layer (5) and means (108) for feeding the continuous, multilayer web along a feed direction (X). Also provided are means (110) for forming the rod (1) around the feed direction (X) and means (111) for cutting the rod (1) into pieces. The machine (100) is configured to dispose the lateral edges (4, 7) of at least one between the first and the second layer (2, 5) in such a way as to make at least one end-to-end splice (3, 6). The machine (100) implements a method for making pieces of a multilayer, cylindrical tubular rod (1).

Description

Technical field [0001] The present invention relates to a method and machine for manufacturing rod sections of a multilayer cylindrical tubular rod suitable for manufacturing generally cylindrical smoker articles. [0002] The present invention also relates to rod sections of multilayer cylindrical tubular rods suitable for manufacturing generally cylindrical smoker articles. Background technique [0003] As described in the patent application WO2014 / 188318, there are known in the prior art a machine for manufacturing smoker’s products in which cylindrical parts of any type of smoker’s product are wrapped in a multilayer web comprising Suitable for strips that impart the required properties. The strip is made of metal material or plastic material, for example. Therefore, the machine described in WO2014 / 188318 is suitable for the direct manufacture of smoker article segments by wrapping multilayer webs around cylindrical parts. [0004] Therefore, there is currently no machine or m...
