Embodiment Construction

[0040] figure 1 A schematic view of a forming device 14 according to the invention is shown, comprising a lower forming part 1 and an upper forming part 5 . The forming device 14 also includes a forming belt 4 which is continuously moved through the forming device 14, more precisely in the lower region against the conveying direction 10 of the material web 3 in the forming device 14, and in the upper region, i.e. Movement in conveying direction 10 between the lower molded part and the upper molded part.

[0041] The material web 3 is deposited on the forming belt 4 in the inlet region 16 of the forming device 14 and is pressed onto the forming belt 4 by means of the rotating device 2 , which can be configured as a roller, by means of a spring 12 or a spring-loadable pressing device. The material strip can be, for example, a single-material strip or a double-material strip, a double-material strip being a material strip with two material strips which are placed on top of each ...

Abstract

The invention relates to a method for producing a hollow tube (11) in the tobacco-processing industry, comprising steps of: conveying at least one flat material strip (3), which has longitudinal extent, in a longitudinal axial direction (10) to a forming device (14); applying the at least one material strip (3) to a forming strip (4) of the forming device (14), wherein the forming strip (4) is moved in the longitudinal axial direction (10) and arranged on a forming strip guide surface (15); preforming at least one material strip (3) in an inlet region (16) of the forming device (14) by means of a rotary device (2), the rotary device (2) exerting pressure on the at least one material strip (3) and the forming strip (4), wherein the preforming comprises pre-bending of the at least one material strip (3) in a direction transverse to the longitudinal extent of the at least one material strip (3); and forming the at least one material strip (3) into a hollow tube (11). Moreover, the invention relates to a forming device of the tobacco-processing industry.

Description

technical field [0001] The invention relates to a method for producing a hollow tube for the tobacco processing industry and a forming device for a strangmaschine for the tobacco processing industry, wherein the forming device is provided for forming at least one flat material The belt is formed into a hollow tube, the material belt is guided in the longitudinal direction through a forming device comprising an upper forming part (Oberformat) and a lower forming part (Unterformat), wherein the lower forming part has a forming belt guide surface, and the forming device also Consists of a format band which is guided or can be guided through the forming device along a guide surface of the forming band. Background technique [0002] Small tubes or hollow tubes, for example formed from cardboard or paper, are used in the tobacco processing industry to provide, for example, in particular filters, for example recessed filters (Rezess filters) or hollow filters. Furthermore, such sm...
