AI Technical Summary

Problems solved by technology

If the knot is not strong enough, there is a danger that the knot will unravel and thus not pull the new end together into the strip
The new end must then be introduced manually into the strip with great difficulty, for which in extreme cases the entire device must be stopped

Embodiment Construction

[0021] exist figure 1 A cutaway section of a device for producing filters with additives for products of the tobacco industry, to which a strip-like, continuous substrate 1 , for example in the form of cotton threads, is fed can be seen. Furthermore, a continuous strip 5 of filter material is fed to the device. The strip 5 of the filter material is conveyed in a known manner through a funnel mechanism 6 to a bong complete set (Formatgarnitur) consisting of a bong bottom 8 and one or more bong upper parts 7, in which In the gun assembly, the strip 5 is compressed to a smaller diameter and fixed in shape with a wrapping tape. The rod 5 is then cut in a subsequent processing station into multi-length filters of a predetermined length. The substrate 1 is conveyed in a guide channel 13 extending through the conveying device 4 to a guide 21 by means of which the substrate 1 is introduced into the rod 5 of filter material.

[0022]In the transport device 4 , the substrate 1 is def...

Abstract

The device has a strand-like continuously supplied carrier (1) i.e. cotton thread, inserted into a continuously supplied strand (5) of a filter material by a feed device (4). The carrier is guided in a guide passage (13), which is formed in the feed device. A low pressure generation device is partially provided in the guide passage for generating low pressure at the device. A control device changes the low pressure in the guide passage. A pressurized air device is attached to the guide passage through a conical annular gap extending into the guide passage.

Description

technical field [0001] The invention relates to a device for producing filters with additives for products of the tobacco processing industry, having the features stated in the preamble of claim 1 . Background technique [0002] The filter is produced as a continuous rod of so-called filter filaments into which the additive-impregnated or wetted substrate is introduced. It is also conceivable to manufacture the filter in a plurality of parallel rods, preferably in two parallel rods in a double rod machine. The filter filament itself consists, for example, of cellulose acetate which has been treated with a chemical for dissolving cellulose acetate, in particular triacetin. The substrate itself can be formed, for example, by continuous threads of a natural or synthetic base material which are crosslinked in such a way that the threads have a certain tensile strength. Such a substrate can be formed, for example, by cotton thread, acetate thread, absorbent tape or similar mate...
