Embodiment Construction

[0038] exist figure 1 The spreading device according to the invention can be seen schematically from the side in FIG. Multiple, in this case double-width, covering material webs 1 are fed to the stretching device on reels not shown, and the bales are separated in the stretching-cutting roller group 10. The covering material web 1 is cut into two parallel covering material webs 2 and 3 of single width. The covering material webs 2 and 3 , which are immediately adjacent to each other laterally after cutting, are then fed to two groups of deflection rollers arranged offset relative to one another in the conveying direction of the covering material webs 2 and 3 4 and 5. The front covering material web 2 shown in the illustration is first introduced into the first deflection roller group 4 and is conveyed downwards on the upper side of the first deflection roller 6 to the second deflection roller 8 and then output it from the underside of the second deflection roller 8 . The in...

Abstract

The invention relates to a spreading device for two or more clad material sheets (2, 3) used for manufacturing at least two parallel strips formed from products of the tobacco-processing industry. The spreading device comprises turning roll subgroups (4, 5) with a number the same as that of the clad material sheets (2, 3) and comprises corresponding single turning rolls (6, 7, 8, 9). The clad material sheets (2, 3) are turned on different side surfaces correspondingly on the turning rolls. The turning rolls (6, 7, 8, 9) are inclined in such a manner that the clad material sheets (2, 3) turned thereon retreat from the turning roll subgroups (4, 5) in a way of shifting sidewise parallelly with respect to the input direction (I, III). The turning roll subgroups (4, 5) are arranged to be shifted relative to each other in the clad material sheet (2, 3) conveying direction.

Description

technical field [0001] The invention relates to a stretching of two or more webs of covering material for the production of at least two parallel strips of products from the tobacco processing industry, having the features of the preamble of claim 1 Device and a device having a spreading device having the features of the preamble of claim 17. Background technique [0002] In machines for the production of products for the tobacco-processing industry, for example not only strip-shaped filter material but also strips of loose tobacco fibers are fastened by means of the covering material web. In order to increase the production speed, it has been proven that at least in the strip forming unit the product is produced in two or more parallel running strips, if expensive pre-cut covering material should not be used. In order to produce the covering material webs which are necessary for this and are fed in parallel, a multiple, especially double-width covering material web is firs...
