Embodiment Construction

[0029] A rod-like article forming apparatus constitutes a part of a cigarette making machine or a filter making machine. As illustrated in FIG. 1, the cigarette making machine comprises a shredded tobacco-supplying device 2 and a forming apparatus 4. The forming apparatus 4 forms cigarette rods.

[0030] More specifically, the supplying device 2 has an endless suction belt, namely a tobacco band 6, which runs in one direction. While the tobacco band 6 travels, a suction face of the tobacco band 6 sucks shredded tobacco in layers to form a shredded tobacco layer. The shredded tobacco layer is transferred toward the forming apparatus 4 along with the travel of the tobacco band 6.

[0031] The forming apparatus 4 includes a wrapping section 8 continuing to the tobacco band 6. The wrapping section 8 receives the shredded tobacco layer and a paper web P at a start end thereof. The shredded tobacco layer and the paper web P pass through the wrapping section 8, and in this process, the shredde...

Abstract

A rod-like article forming apparatus comprises an endless garniture tape (10) used for forming a tobacco rod (R) with shredded tobacco and a paper web (P), a driving drum (12) for causing the garniture tape (10) to travel in one direction, and a plurality of presser rollers (34) for pressing the garniture tape (10) against the outer circumferential surface of the driving drum (12). The presser rollers (34) increase the contacting force of the garniture tape (10) with respect to the outer circumferential surface of the driving drum (12).

Description

TECHNICAL FIELD [0001] The present invention relates to a forming apparatus for continually forming a rod-like article obtained by wrapping a filling material in a web. BACKGROUND ART [0002] This kind of forming apparatus is incorporated into a cigarette making machine or a filter making machine. For instance, Unexamined Japanese Patent Publication No. 8-214854 discloses an example of a cigarette making machine. The making machine disclosed in the publication includes a wrapping section as a forming apparatus, and the wrapping section has an endless garniture tape. The garniture tape receives a paper web and shredded tobacco as a filling material, and causes the paper web to travel with the shredded tobacco in one direction. In this process, the shredded tobacco is compression-molded into a rod-like shape and subsequently wrapped in the paper web by using the garniture tape. As a result, a tobacco rod is continually formed. [0003] The garniture tape is wound around a driving drum an...
