Definitions

  • the invention relates to a process for the production of an endless honeycomb strip consisting of flat, side-by-side, partially glued strips, which can be pulled apart to form a honeycomb structure by stretching in the longitudinal direction of the strip, film strips being pulled continuously from several coils, on one side with parallel in the longitudinal direction of the strip Glue strips running to each other, having the same spacing from one another, and then placed one above the other, the glue strips of the one film web being offset by half a strip spacing from those of the film web above or below, whereupon the multilayer film tape formed therefrom for mutual fixing of its individual web layers treated by pressure and / or temperature and finally divided transversely into strips of the desired width, which are stacked one above the other and pressed under pressure to form the endless honeycomb belt will.
  • the invention further relates to a device for performing the aforementioned method.
  • the method mentioned at the outset can be found in Canadian Patent 1,078,296.
  • the processing is carried out by four coils, the strips being separated from the front end of the multilayer film strip.
  • the invention has for its object to develop an inexpensive manufacturing process that can be carried out on compact systems with high capacity.
  • the said gluing preferably hot melt
  • film strip sections of the same length are separated, with respect to their length correspond to a multiple of the final strip width and are stacked on top of one another to form intermediate stacks, which form a buffer store and are individually pressed into packets, which are successively divided into the strips mentioned, which are pressed under heat to the honeycomb strip.
  • the glue strips are thus preferably formed from hot melt, which is applied from the start in strips, but not in bead-like beads.
  • the purpose of all cooling devices is to cool the materials heated for gluing back to a maximum temperature that is permissible for handling before further processing.
  • the cooling devices can be integrated into the conveyor devices. Contamination of the deflection or pressure rollers by the hot melt is thus avoided.
  • the interchangeable magazine station serves to achieve a high capacity, which enables the formation of intermediate stacks and thus a high performance of the second cross cutter, even though the processing is only carried out by two coils.
  • the accumulation device formed by the press channel works continuously or in the step cycle of the second cross cutter; the strips pent up under pressure are thus conveyed continuously or intermittently through the press channel.
  • FIGS. 1 and 2 The system according to FIGS. 1 and 2 is used to produce an endless honeycomb belt and comprises the following stations from left to right:
  • a processing station 1 comprises two coils 2, from each of which a film web 3 is continuously drawn off, which can be metal foils.
  • deflection devices 4 for example made of rollers or the like. can exist.
  • the unwinding station 1 is followed by a coating station 6.
  • this comprises a hotmelt applicator unit 7 which has at least one slot nozzle 8 with an interchangeable slot mask 9 (see FIG. 4) for the production of glue strips 10 on the top Film web side (see Figure 5).
  • glue strips 10 run in the longitudinal direction of the film web 3; the strips of glue 10 lie parallel to one another and have the same spacing from one another, the strips of glue 10 of the lower film web 3 are offset by half a strip spacing relative to the glue strips 10 of the upper film web. If the width of each glue strip 10 is denoted by a, the clear distance between two glue strips 10 is preferably three a.
  • the strip geometry determines the size of the honeycomb core diameter.
  • Hotmelt is a solvent-free, environmentally friendly, heat-reactive adhesive that is applied in strips, but not in bead-like beads.
  • the width of the film web can e.g. two slot nozzles are provided, the slot opening through sheets, foils or the like. is coverable, in which the openings are punched at the intervals that are desired for the glue strips 10.
  • the coating station 6 is followed by a cooling station 11 for the glued film webs 3.
  • this cooling station 11 is formed by cooling rollers 12, over which the film webs 3 are guided and which bring about the transport and the tension of the film webs, which is required for a clean application of adhesive.
  • a laminating station 13 Downstream of the cooling station 11 is a laminating station 13, which is formed by a pair of rollers 14 through which the two film webs 3, which are now superimposed, are guided simultaneously be, the deflection rollers on the inlet side serve as edge control of the film webs.
  • This laminating station serves to bring the two film webs 3 together and to fix them to one another, the two film webs being only to be bonded to the extent that a relative displacement between the film webs is prevented.
  • a first cross cutter 15 is arranged behind the laminating station 13, which can be designed as a rotary cross cutter, so that a continuous removal of the film webs 3 from the coils 2 can be maintained.
  • This first cross cutter 15 separates film strip sections of the same length from the end located at the front from the now double-layer film web, the length of which corresponds to a multiple of the width of the strips 16 to be produced later, the length being selectable and, for example, a maximum of 1300 mm.
  • These double-layer film strip sections are stacked in an interchangeable magazine station 17, which forms a buffer store and has a drawer slide provided with two storage levels 18, 19.
  • this stack 20 is automatically fed to a heating calender 21, while simultaneously double-layer film strip sections are continuously stacked to form a stack 20 in the second drawer level.
  • the heating calender 21 the stacks 20 fed from the respective storage level 18 or 19 to the exchangeable magazine station 17 are successively heated to the required temperature and pressed or baked under the required pressure to form a package 22.
  • the package 22 then arrives at a downstream outlet table, which serves as a connecting and cooling section 23 from the heating calender 21 to a second cross cutter 24.
  • the latter has a cutting knife 25 which is controlled in a vertical plane and with which a knife bar 26 arranged above the package 22 also coexists partial stamps or hold-down strips 29 and a counter knife 27 located below this package 22 are assigned.
  • the delivered packages 22 are trimmed if necessary and then cut into strips 16, the width of which, according to the final honeycomb height, can be freely adjusted. Any first and remaining cuts are automatically ejected and collected.
  • a press channel 28 Arranged below the second cross cutter 24 is a press channel 28 forming a stowage device, which at its entry has a partial stamp 29 which presses the last cut strip 16 into the press channel and engages in the free or intermediate spaces thereof, e.g. Retainer 30, which can be controlled electro-pneumatically or electromagnetically, has strips 16 for the strips 16 already located in the press channel 28.
  • the endless honeycomb belt 32 thus formed then passes through a cooling device 33.
  • the feed in the press channel 28 can take place continuously or in steps.
  • the preferably arcuate press channel 28 exerts such a high back pressure on the pre-conveyed strand that the strips 16 stacked one above the other are firmly bonded to one another under heat and pressure.
