Embodiment Construction

[0084] figure 1 The state of the first material web 25 and the second material web 26 after the first material web 25 and the second material web 26 have been joined is shown schematically in a section transverse to the two material webs. It can be seen here that the first material strip 25 has a positioning adhesive 17 , such as glue, on its upper side. The second material web 26 is laid onto the positioning adhesive 17 .

[0085] The first material web 25 has edges 13 and 14 on the left and right and the second material web 26 has edges 15 and 16 on the left and right.

[0086] In addition, seam gluing 18 has been carried out on the first material web 25 for a joint with the second material web 26 that protrudes beyond the first material web 25 on the right. The parts are set to glue. It is also possible to provide a seam tape, for example a seam tape 18 on one side of the first material web 25 and a further seam tape on the opposite side of the material web 26 . The glu...

Abstract

The invention relates to a method for producing an at least double-layer tubular rod for the tobacco processing industry and a device for producing an at least double-layer rod for the tobacco processing industry. For the production of strips (31) the base material strip (24) is cut into a first material strip (25) with a first width and a second material strip (26) with a second width, wherein the first or the second The width of the two material webs ( 25 , 26 ) is controlled and the cutting is controlled such that the width of the material webs is set to a predetermined value.

Description

technical field [0001] The present invention relates to a method for the manufacture of at least double-layered tubular rods for the tobacco processing industry. [0002] Furthermore, the invention relates to a device for the manufacture of at least double-layered tubular rods for the tobacco processing industry. Background technique [0003] In the tobacco processing industry, rods, such as tobacco rods, filter rods or hollow tubes, are produced for cutting into individual segments, which are then further processed, for example, into filter cigarettes. [0004] In addition, small tubes, such as cardboard or paper tubes, are used, for example, to provide special filters, recessed filters (Rezeß filters) or hollow filters. Furthermore, such small tubes are also used as spacers in Heat-not-Burn-products. The corresponding small tubes should have a certain stability, so it is known to make multi-walled paper tubes. Such small tubes are cut to size from hollow tube strips. ...
