Definitions

• the invention relates to a device for applying a flowable mass to a moving material web, in particular for applying glue to a paper web, according to the preamble of claim 1.
• a device of this type has become known from DE-43 09 951 A1. It is preferably used as a gluing device in a filter attachment machine for the production of filter cigarettes. With this device, liquid glue from a supply is continuously applied to a topping paper strip, which is then cut into topping sheets for connecting tobacco sticks and filter plugs. Of course, such a device can be used to apply flowable compositions of the most varied types to material webs of the most varied types.
• the invention has for its object to produce a perfect mass application on a running material web, contamination of the application and guide devices by the mass are avoided as much as possible.
• the invention offers the advantage of a uniform, flat application of mass to moving material webs, so that edge contamination is avoided.
• the narrow pressure medium prevents portions of the flowable mass from being pushed out laterally under the material web and contaminating the edge regions of the web. It is particularly advantageous to use the device proposed according to the invention in a glue apparatus of a filter attachment machine for the production of filter cigarettes, because there glue squeezed out laterally under the additional paper strip leads to annoying stains in the can later lead to visible edge area of the insert paper on the finished product.
• Another important advantage of the invention is that due to the design of the pressure medium with recesses, glue-free zones are taken into account, so that the mass to be applied is not pressed by the pressure medium into areas that should not be coated with the mass.
• the invention When a covering paper strip is glued in a filter attachment machine, such glue-free zones are, for example, narrow strips of perforation traces provided on both sides in the covering paper strip.
• the invention thus ensures that the perforations of the covering paper remain free of glue. Because of the more even and cleaner gluing of the covering paper strip, the invention has the additional advantages, in particular in the filter attachment machine, that less contamination occurs in the area of the glue apparatus, on the guides of the covering strip and on the knife apparatus with which individual covering sheets are separated from the covering paper strip arise and that the wrapping of the cigarettes with topping papers can take place with less pressure on the rolling hand, which leads to less loss of hardness of the cigarettes and to rounder cigarettes, that is to say improved product quality.
• the reduced fluctuation in the degree of ventilation of the cigarettes as a result of the invention also leads to products of higher quality.
• FIG. 1 shows a section through an exemplary embodiment according to the invention in a schematic illustration
• FIG. 2 shows a top view of the roller arrangement of the device and shown schematically in FIG. 1
• Figure 3 shows a section through a variant of the embodiment shown in Figure 1.
• FIG. 1 A device according to the invention for applying a flowable mass to a moving material web is shown schematically in FIG. 1 in a cross section.
• This example is a glue application device, as can be used in a filter attachment machine for the production of filter cigarettes.
• a filter attachment machine is shown and described, for example, in FIG. 1 of US Pat. No. 4,249,547 (corresponding to DE 30 13 979 A1).
• a coating compound 2, in the exemplary embodiment shown a glue, is kept ready in a storage container 1.
• a removal roller 4 rotating in the direction of the arrow 3 dips into the mass and carries a layer of glue on its circumference in a known manner.
• This layer of glue is taken over by an application roller 7 touching the circumference of the removal roller and rotating in the direction of arrow 6 and transferred as a coating to a material web 11 moving in the direction of arrow 8 and tangent to application roller 7 in an application zone 9.
• the material web 11 is guided over rollers 12.
• a pressure means in the form of a counter pressure roller 13 presses the moving material web 11 against the peripheral surface of the rotating application roller 7.
• FIG. 2 shows a plan view of the arrangement of the counter-pressure roller 13 and the application roller 7 in the pressure zone 9 in the direction of the arrow II in FIG. 1.
• the application roller 7 is seated on a shaft 14 which is mounted in the machine housing 16.
• the counter-pressure roller 13 is mounted on a pivot lever 17 pivotably mounted on the housing 16.
• the pivot axis of the pivot lever 17 is designated 18.
• the shaft on which the counter-pressure roller 13 rotates without its own drive has the reference number 19.
• the material web 11 is moved through in the arrow direction 8 between the application roller 7 and the counter-pressure roller 13.
• the counter-pressure roller is narrower than the material web 11. This ensures that the glue layer transferred from the application roller 7 to the material web in the areas in which the counter-pressure roller 13 bears against the material web and is evenly distributed that the glue is not pressed out laterally at the edges of the material web 11. This results in less Contamination in the area of the glue apparatus and on the downstream guides and units for guiding and further processing the material web.
• the material web 11 which in the exemplary embodiment shown is a covering paper strip, is provided with two perforation tracks 21, which consist of two parallel rows of holes. As is known, these perforations serve to impart desired air permeability to the filters of the filter cigarettes wrapped with the covering paper.
• the application roller 7 is designed in a known manner so that no glue is transferred to the material web 11 in the areas of the perforation tracks 21. The principle of such a roller design is described, for example, in US Pat. No. 4,249,547 already mentioned above.
• the counter-pressure roller In order to prevent glue from being pressed into the areas of the perforation tracks 21 by the action of the counter-pressure roller 13 and to close the perforations, the counter-pressure roller has radial recesses or punctures 22 on its circumference, through which no pressure on the areas of the perforation tracks Material web is exercised. This largely prevents, or at least greatly reduces, fluctuations in the degree of ventilation of the finished cigarettes.
• the surface of the counter pressure roller 13 is preferably elastic. It can be made of rubber or silicone. For an optimal effect of the counter-pressure roller 13, only a small contact pressure of the order of about 0.5 bar is required.
• the counter-pressure roller does not have its own drive, so that it is only set in rotation by the moving material web 11. It can be locked on the swivel lever 17 for quick interchangeability.
• a stationary pressure element 23 can also be provided as the pressure means, as is shown schematically in FIG. 3.
• This pressure element 23 can consist, for example, of a spring plate or plastic and, like the counter-pressure roller of FIGS. 1 and 2, can be attached to a pivot lever 24 mounted in the machine housing 16. Otherwise, the representation in FIG. 3 corresponds to that in FIG. 1.
