Definitions
- the invention relates to a device for producing corrugated cardboard on one side by gluing together a corrugated sheet and a smooth cover sheet, comprising a corrugated roller arranged in stamping engagement with a corrugated counter-roller for producing corrugations on a cardboard or paper web: and for guiding them formed corrugated path is provided around a part of its periphery, a gluing device for gluing at least the tips of the corrugated path guided around the corrugated roller, a guide roller for guiding the cover sheet against the corrugated roller and at least one deflecting roller for guiding the corrugated cardboard path in the form of the corrugated sheet lying on the cover sheet away from the corrugated roller and for tensioning the cover sheet against the corrugated sheet towards the corrugated roll by a predetermined circular section thereof.
- the invention also relates to a method for producing single-sided corrugated cardboard, in particular using this machine.
- a generic device is known for example from WO 95/03166, with which the gluing of a smooth cover sheet to the tips of a corrugated sheet is to be achieved without the use of high pressure.
- the guide roller serves as a smooth pressure roller for pressing the cover sheet against the wave track.
- it is floating with respect to the corrugating roller while leaving a predetermined gap.
- the gluing between the ceiling and shaft web takes place in two zones, first in a wrapping area around the heated corrugated roller, and then in a wrapping area around the likewise heated deflection roller.
- the pressure roller is set to exert only a slight pressure on the corrugated cardboard web. This is to minimize damage to the corrugated cardboard produced in this way.
- the pressure roller is slightly displaced due to the low pressure force, so that when the ⁇ er corrugating roller rotates, the pressure roller always abuts the tips of the corrugating roller.
- the result is an unsatisfactory quality of the corrugated cardboard, which at best has unsightly linear press marxes and in the worst case is very susceptible to tearing.
- the constant loading of the corrugated roller by the press roller also causes a high level of wear on the corrugated roller, which can only be prevented to a limited extent by coating it costly, for example with a jacket made of tungsten carbide. Even with only slight wear, it can be assumed that the distance between the pressure roller and the reefing roller will not be uniform over their length, so that the webs are subjected to different pressure over their width. and accordingly will have different adhesive results. Furthermore, this known arrangement is time-consuming and personnel-consuming in normal operation, since the gap between the pressure roller and the reefing roller must be readjusted when the paper type is changed.
- the invention is therefore based on the object of substantially improving the quality of corrugated cardboard on the side that can be achieved with conventional machines for the most varied types of paper, the gluing being particularly simple, ie easy with relatively simple, inexpensive and best-performing machines built-in center should be reliable.
- a guide element extending over the length of the corrugating roller is provided between the guide roller and the corrugating roller, around the cover sheets with the corrugated tracks guided around the corrugating roller to bring into contact and thus to determine the beginning of the wrap-around circle section, the guide element being arranged held biased against the corrugating roller and comprising a support surface which is adapted to the circumferential surface of the corrugating roller and at the same time has at least two tips on the entire length overlaps the corrugated tracks lying on the corrugated roller.
- this method comprises the following steps in solution to the task: generating corrugations in a paper web to form a corrugated sheet; Applying glue to at least the tips of the wave path; Tensioning the cover sheet between two rollers such that a predetermined length of the cover sheet is pressed against the glued wave track; Establishing the contact between the cover sheets and the shaft sheets with externally acting guiding and / or pressing means in such a way that the cover sheets are brought into contact with at least two tips of the wave tracks over the entire sheet width at the same time.
- the guide element extends in the circumferential direction of the ripping roller over only a part of the predetermined loop section.
- the guide element mainly serves to prepare the adhesive surface by making the glue penetrate the paper evenly.
- the paper webs are glued by means of a fixation in the wrapping area, the elastic tension of the top web preventing the inhomogeneous shrinkage of the paper fibers during gluing and drying, which leads to a so-called "washboard effect".
- Paper is a natural product and inevitably has a certain innomunity. For this reason, wrinkling occurs more frequently in the cover sheet, which leads to problems particularly in the case of the known welipoard machine mentioned above, which operates with reduced contact pressure. In such machines, the folds often occur on the last press roll or guide roll, ie immediately before the corrugation with the corrugated web, so that the quality of the corrugated cardboard is severely impaired.
- This problem can be avoided as far as possible in a particularly expedient embodiment of the invention, in that the corrugated roller and the guide element are operatively connected to one another in such a way that the contact between the cover sheet and the wave track is from the center - 5 -
- this spreading function can be achieved in that the guide element is provided with an edge which is bent outwards and faces away from the loop section.
- the spreading function can also be achieved or enhanced by positive bombing of the corrugated roller.
- the guide element is divided in its longitudinal direction into at least two parts which can be arranged to be resiliently deflectable independently of one another against the corrugating roller. This means that even contact pressure can be achieved across the entire width of the ceiling and corrugated sheet, even when the corrugated roller is worn.
- An expedient design consists in that the cross section of the contact surface of the guide element is essentially adapted to the circulating circuit of the corrugating roller.
- ge ⁇ is ensured in that the pressure is always applied to the tooth tips of the fluted roller, so that a movement of the guide elements ⁇ is closed relative to the teeth of the corrugating roll virtually exclusively.
- the direct pressing of the pressing element against the cover sheet causes an only insignificant braking effect, so that the bonding of the sheets is not affected.
- This effect can be strengthened even more and the bonding in the wrapping area of the corrugating roller can be further improved if the speed of the deflecting roller as the corrugated cardboard web can be set in advance.
- the deflection roller can be designed to be adjustable in the sense of a change in the loop section in an advantageous development of the invention.
- FIG. 1 is a schematic side view of a single-sided corrugated cardboard machine according to the invention
- corrugations are generally formed in preheated paper webs 8 by guiding them between two corrugated corrugating rollers 1 and 3 which are arranged in opposite directions, are arranged axially parallel and are in stamping engagement with one another.
- the corrugating rollers 1, 3 are also heated by means of steam or in some other appropriate way in order to increase the elasticity of the paper web.
- the paper web provided with corrugations, ie the corrugated web 8 is guided around the lower corrugating roller 1, wherein a gluing device known per se and assigned to the corrugating roller 1 glues the tips of the corrugated web.
- a likewise preheated, smooth paper web 9 provided as a cover web is fed to the corrugating roller 1 via a guide roller 2.
- This guide roller 2 which is also known by means of steam
- the cover sheet 9 is guided between the guide roller 2 and a deflecting roller 4 so that it extends against part of the circumference of the corrugated roller 1, i.e. is held elastically tensioned over a predetermined wrap angle thereof.
- the bearing of the deflecting roller 4 can be configured so as to be adjustable, in order to change the wrap angle, as can be seen, for example, from the dash-dotted arrangement in FIG. 1. - Possibly. If necessary, the paper webs can be preconditioned in addition to the measures described.
- a guide or pressure element 5 is assigned to the latter in the area between the guide roller 2 and the corrugated roller 1 and serves to establish the first contact between the cover sheet 9 and the glued wave track tips 8.
- the guide element 5 is suitably opposite the rifle
- the roller 1 and thus the wave track tips are arranged so as to be resiliently deflectable and thus guide the cover sheet 9 with only a small contact pressure.
- the gluing between the roofing membrane 9 and wave path tips 8 therefore not only take place in the actuation area of the guide element 5, but mainly with the help of the heating of the corrugating roller 1 over the entire wrap angle and along the corrugated cardboard path 6 to the deflection roller 4.
- the guide element 5 rather carries out an important preparation step for the actual gluing.
- the cover sheet 9 In order to ensure sufficient tension of the cover sheet 9 and its contact pressure against the corrugated sheet 8 over the wrap angle and around the deflecting roller, and in particular to generate a sufficient tensile force in the direction of the deflecting roller 4, the latter is advanced with respect to the corrugation ⁇ cardboard web 6 driven.
- the guide roller 2 can also be provided with a jacket to increase their frictional force.
- the cover sheet is thus guided exclusively between the guide roller 2 and the deflection roller 4, so that the braking effect of the guide element 5 becomes essentially insignificant.
- the cover sheet 9 acts as a kind of belt which holds the wave track pressed against the corrugated roller and at the same time is in adhesive contact over its entire width with the glued tips of the wave track.
- the required frictional resistance forces exerted on the cover sheet 9 in front of the bonding area can also be achieved by means of at least one further deflecting roller 10, which can be driven if necessary, so as to influence the frictional engagement to a greater extent.
- the guide element 5 is provided with an essentially smooth guide surface directed towards the corrugating roller 1, which is circular in cross section.
- the center of the circle essentially corresponds to the center of the axis of the corrugating roller 1.
- the pressing surface is preferably essentially rigid and extends over several teeth, so that the guide element rests at several points simultaneously.
- the guide surface is also divided over its length into several parts, each part being arranged to be resiliently deflectable against the corrugating roller 1. This can be achieved in that each guide surface part is arranged at the end of a lever arm, which lever arm can be deflected against the force of a spring element, for example in the form of a fluid piston.
- each guide surface part with a spring element or air cushion arranged directly under the guide surface against the corrugation roller 1, so that the guide surface exerts essentially radial pressure on the corrugation roller 1.
- the corrugated roller 1 is formed in a known manner with parallel circumferential guide slots 12 which, in cooperation with fingers arranged inside the roller 1 and controllable from the slots, detach the corrugated cardboard web 6 from the corrugated roller.
- the distances between the guide slots correspond to the subdivision of the guide surface of the guide element 5 or the pressure bar.
- corrugated roller with guide slots corresponds to only one of several known possibilities for quickly, easily and reliably detaching the corrugated cardboard web 6 from the corrugated roller 1.
- the guide element described can be used with other types of corrugated rollers, e.g. rollers or the like working with negative pressure can also be used successfully.
- the subdivisions of the guide surface are selected in order to compensate for any wear or bombing of the roller and thus to exert an optimally uniform pressure over the entire surface.
- the guide element 5 As shown in FIG. 3, can be provided with a leading edge 13 which is slightly bent outwards or beveled. In this way, the guide element 5 acts simultaneously as a pressing and spreading means, whereby it establishes the defined contact between the corrugated and cover sheet 8 or 9 only in the middle of the paper sheets and then increasingly towards their edge areas. Any folds that occur will automatically run outwards before gluing.
- This effect can also be achieved or intensified by designing the corrugated roller 1 with a bombage.
