SU1743891A1 - Method of manufacturing three-ply panels with honeycomb filler, and device therefor - Google Patents

Abstract

SUMMARY OF THE INVENTION: The transversely corrugated tapes 1 are connected to the substrate 2 at intervals of 3, which are curved towards the vertices of the corrugations when the substrate is displaced along the corrugations before the gap is closed, as a result, longitudinal stiffening ribs are formed and the outer layers 5 and 6 are pasted onto this middle layer, In the device for carrying out the method, after the mechanisms for manufacturing the transversely corrugated tapes and their duplication with the substrate, a transfer conveyor of elastic rolls located above and below the tape is installed, at the same time, the axes of the end sections of the rolls are turned in the feed direction of the ribbons, and the apex of the formed arc is oriented towards the axis of the ribbons. During rotation of the rolls, due to their curvature, which remains due to elasticity in the plane of the tape, transverse compression of the tape occurs, causing bending of the gaps 3 and the formation of longitudinal ribs, which are simultaneously glued together with the ends of the corrugated tapes. 2 sec. f-ly, 22 ill. with s

Claims (3)

Claim 1. A method of manufacturing a three-layer panels with a honeycomb core, which consists in forming the middle layer, in which the transverse corrugated element is made, connect it to the substrate and perform longitudinal reinforcing ribs in it, applying glue to the substrate and corrugations, and in connecting the middle layer with the outer layers, characterized in that, in order to increase the strength and rigidity of the panel in the longitudinal direction, when forming the middle layer, a transversely corrugated element in the form of several corrugated tapes is placed on dlozhke with a gap between the ends of the corrugation equal to double the corrugation height, and then on the substrate along the lines of corrugations and the ends in the middle of the gap operate recess arch substrate at intervals in the direction of the corrugation peaks and corrugation is slid along the substrate to the circuit gap. 2. A device for the manufacture of three-layer panels with honeycomb, containing mounted on a frame holders of rolls of tape material, a transverse-corrugating mechanism, an applicator mechanism, a mechanism for connecting transversely corrugated tapes with a substrate, a mechanism for forming a middle layer, a mechanism for connecting the middle layer to the outer layers in the form of a press conveyor and a cutting mechanism, characterized in that, in order to increase the strength and rigidity of the panel in the longitudinal direction, it has a Between the mechanism for connecting transversely corrugated tapes with the substrate and the press-in conveyor, the lateral compression of the tape, including means for forming bending and bending lines of the substrate and a transfer conveyor, made in the form of sequentially arranged elastic arcuate rolls, bent so that the apex of the arc lies in the plane of the feed path the tape in its center, and the axis of the end sections are rotated in the direction of feed of the tape.
