Verfahren und Vorrichtung zum Formen einer längsgewellten Bahn

The invention relates to a method and to a device for continuously shaping a plane web to give a lengthwise corrugated web while avoiding folds and cracks in the web. The inventive method is characterized by guiding and shaping the web in the zone to be shaped in a spatially continuous manner. Every imaginary line lying in the web center surface and extending in the direction of transport covers substantially the same distance during shaping in the zone to be shaped. With progressive shaping the web lines not lying in the edge region are deflected perpendicularly to the web plane, the maximum value of said deflection being the greater the farther away the respective web line is from the edge of the web. In order to obtain a constant web length, a lower deflection in one direction is compensated for by a greater deflection in a different direction, thereby causing all web lines in the zone to be shaped to cover substantially the same distance.

Production of paper webs

An extensible paper web is made by reducing the width of a paper web, by an amount not exceeding the natural contraction capacity of the web, by forming a series of lengthwise corrugations spaced across the web and drying the web by bringing it into contact with at least one heated metallic surface, so that the crests of the corrugations contact the heated surface and the portions of the web between the crests contract to produce a substantially smooth-surfaced web. As described with reference to drawings (not shown), paper in an incompletely dried state is passed over a bowed roll with a cover of rubber having circumferential grooves. The paper is applied to the roll on the outwardly bowed side, is forced into the grooves by compressed air, or a brush or simply by its own tension, and leaves the roll, in a condensed state, on the inwardly bowed side. The drying of the paper is then completed, e.g. between a conventional dryer roll and a felt. The paper may be passed over the bowed roll more than once or more than one such roll may be provided if necessary to give enough condensation.

A web of fibrous material is treated to render it particularly adapted to be gathered laterally and enclosed in a wrapper to make a filter cord subdividable into effective filters for cigarettes, by advancing a moistened essentially inelastic web 1 of the material through the nip between a pair of meshing heated corrugating and stretching rollers 8, 9 having narrow circumferential grooves 20 alternating with narrow circumferential ribs 21 whereby the web is longitudinally corrugated and laterally stretched to loosen and expose fibres without substantial impairment of the transverse continuity of the web 1, and advancing the corrugated and stretched web 1 emerging from the nip in contact with the roller 9 through an appreciable wrap angle to partially dry and reharden the web to preserve the structure imparted thereto by passage through the nip. As shown in Fig. 1, the smooth web 1 passes from a roll 2 through perforating apparatus, preferably comprising a pronged or toothed roller 3 and a counter roller 4 one of which is driven, to produce irregularly-shaped frayed portions extending out of the plane of the web. The perforating device 3, 4 may be followed by a similar device, e.g. rollers 3, 4 with their positions reversed to form frayed projecting portions on the other side of the web. The web 1 is then rendered yielding by passage through a moistening device comprising a rotating metal roll 5 dipping into a water bath 6 and a rubber pressure roller 7. Alternatively, the web may be rendered yielding by spraying it with a liquid or by submitting it to a steam treatment. The web 1 then passes around meshing grooved corrugating and stretching rollers 8, 9, 10, see also Fig. 2, all of which are preferably adjustably heated, e.g. by interior electrical heaters, to a temperature between 100 C and 500 C. Preferably, the rollers 9, 10 mesh to a greater extent than the rollers 8, 9 to deepen the corrugations and further laterally stretch the web 1. After each corrugating ...
