Embodiment Construction

[0063] figure 1 An apparatus 100 for making variable curl paper is shown. The apparatus includes, among other components, a cross-machine crimp roll 102, and / or a variable crimp roll 104. In the preferred example, the cross-machine crimp rolls 102 are replaced by variable crimp rolls 104 . The apparatus also includes a lateral sheet cutting mechanism 106 configured to cut the paper to a desired width before it is curled by the rollers. A roll 108 of sheet-like strip material, such as paper, is provided and fed into take-up rollers. The drive and brake mechanism 110 feeds sheet-like strip material from the roll 108 . Mechanism 112 ensures that the strip material enters the take-up roll at the desired tension. Control electronics 114 are provided to control the system during operation.

[0064] The variable curl rolls 104 comprise a set of two interleaved rolls. Each crimping roll is corrugated across its width and also around its circumference. The crimping rolls are syn...

Abstract

The present invention relates to a method of manufacturing variable crimped web material. The method comprises: feeding substantially continuous web material; crimping a first region of the web material at a first crimp value; and crimping a second region of the web material, adjacent the first region, at a second crimp value. The web material is crimped using a set of two rollers, each roller being corrugated across at least a portion of its width and corrugated around its circumference, the rollers being configured such that the corrugations across the width of the rollers interleave with each other to crimp the web material, and such that the troughs of the corrugations around the circumference crimp the web material at the first crimp value, and the peaks of the corrugations around the circumference crimp the web material at the second crimp value. The present invention also relates to an apparatus for manufacturing crimped web material, and a method of manufacturing air flow directing elements for smoking articles.

Description

technical field [0001] The present invention relates to a method of making variable crimp strip material. The invention also relates to an apparatus for producing variable crimped strip material. The invention also relates to a method of manufacturing an air flow directing element for a smoking article. Background technique [0002] Methods and apparatus for producing crimped web material for use in smoking articles are known in the art. Known methods of producing crimped web material include interleaved rolls that produce crimped web material having a generally constant level of crimp along the length of the web material. [0003] Methods and apparatus for forming air flow directing elements for smoking articles are also known. Known methods for producing such an air flow directing element with a variable resistance to draw along its length include the use of multiple segments of different resistance to draw. Using multiple segments increases the manufacturing complexit...
