Patent number: 7237557Abstract: Apparatus for the application of adhesive to one side of a running web of tipping paper for use in filter cigarette makers has a single source of adhesive or two or more sources containing identical or different adhesives, and one or more conduits leading from the source(s) to one or more nozzles which applies or apply one or more films of a single adhesive or of different adhesives to selected portions of the one side of the web. The rate of admission of adhesive(s) to the nozzle(s), including interruption and restarting of admission of adhesive(s), is regulated by one or more valves each having a body receiving a rotary valving element provided with one or more peripheral projections and/or recesses serving to regulate the rate of flow of adhesive toward the single nozzle or the respective nozzles. The rotary elements of two or more valves can constitute disc-shaped sections of a single rotor confined in a valve body common to all valves.Type: GrantFiled: March 29, 2004Date of Patent: July 3, 2007Assignee: Hauni Maschinenbau AGInventors: Berthold Maiwald, Torsten Mörke, Karl-Heinz Pawelko

Patent number: 7040325Abstract: Adhesive-coated bands of paper, tipping paper or plastic foil are convoluted around discrete one-piece or composite rod-shaped articles, such as coaxial plain cigarettes and filter mouthpieces, during travel through a rolling zone bounded by a pair of surfaces at least one of which moves relative to the other. The inlet of the rolling zone receives articles, each of which carries a non-convoluted band, from a conveyor which forms part of a pressing device operative immediately ahead of the inlet of the rolling zone and serving to press successively delivered bands against the respective articles and to effect an at least slight flattening of the articles immediately prior to entry into the rolling zone. The width of the path for the articles increases at the outlet of the rolling zone or immediately downstream of such outlet.Type: GrantFiled: March 13, 2002Date of Patent: May 9, 2006Assignee: Hauni Maschinenbau AktiengesellschaftInventors: Manfred Dombek, Berthold Maiwald

Patent number: 6964230Abstract: An improved method of and an improved apparatus for detecting and correcting unsatisfactory patterns of adhesive is applied to a running web of paper or the like in a tobacco processing machine by a cyclically operated paster. A linear scanning camera is employed to take pictures of groups of at least some of the patterns which are applied during successive cycles of the paster, and such pictures are displayed and compared with a reference image of satisfactory patterns and preferably also with additional reference images. The results of comparison are relied upon for the making of corrections, for example, by changing the operation of the paster and/or by changing the direction of advancement of the web between the paster and the camera.Type: GrantFiled: April 9, 2004Date of Patent: November 15, 2005Assignee: Hauni Maschinenbau AGInventors: Torsten Mörke, Rainer Steinfatt, Berthold Maiwald, Karl-Heinz Pawelko

Patent number: 6645133Abstract: A web of air-permeable uniting band material for use in a filter tipping machine is advanced lengthwise by a first pair of driven rollers and a second pair of driven rollers, first through a magazine which is located between the two pairs of rollers, thereupon around a roller-shaped flanged adjustable braking device which is located upstream of the second pair of rollers, and around an adjustable curling device between the braking device and the second pair of rollers. The braking action is regulated for the purpose of subjecting the running web to a predictable curling action. This enhances the quality of filter cigarettes wherein the tobacco-containing and the filter material-containing parts are connected to each other by adhesive-coated uniting bands constituting sections of the thus treated web.Type: GrantFiled: June 22, 2000Date of Patent: November 11, 2003Assignee: Hauni Maschinenbau AGInventors: Berthold Maiwald, Torsten Mörke

Patent number: 6543457Abstract: The application of adhesive to selected non-perforated sections of one side of a running web of tipping paper in a filter cigarette making machine is carried out in such a way that the adhesive is invariably applied only to the non-perforated sections which alternate with perforated sections. To this end, the speed of advancement of the web along its path past an adhesive applicator and thereupon through a severing unit (which subdivides the web into a file of successive uniting bands to be wrapped around filter mouthpieces and plain cigarettes) is temporarily altered when a comparison of first signals denoting detection of successive perforated sections of the running web with second signals denoting the frequency of severing of the web in the severing unit indicates the need for a temporary change of the speed of the web upstream of the adhesive applicator. The latter is installed at a fixed distance from the severing unit.Type: GrantFiled: June 8, 2001Date of Patent: April 8, 2003Assignee: Hauni Maschinenbau AGInventors: Berthold Maiwald, Torsten Mörke, Karl-Heinz Pawelko

Publication number: 20020144698Abstract: The friction coefficient of the product-conveying and/or treating surface of a drum-shaped or belt-shaped conveyor can be restored or maintained at a desired value by the application thereto of a film of polyvinyl acetate or a dispersion of acrylate, preferably on top of a layer of caoutchouc of the like. The conveyor can cooperate with a stationary or mobile rolling member to convolute adhesive-coated uniting bands around groups of coaxial plain cigarettes, cigars or cigarillos and filter mouthpieces, or it can serve as a means for transporting continuous strips or webs or series of discrete bands in tobacco processing and/or other plants.Type: ApplicationFiled: April 4, 2002Publication date: October 10, 2002Inventors: Berthold Maiwald, Henning Thiele
