Definitions
- the present invention relates to a honeycomb or cell structure of the type employed especially for the fillings or linings of various kinds of constructions known as sandwiches, panels, partitions, etc. for the building trade, aircraft construction, etc.
- Pro-forming makes it possible to give the cells varied geometrical patterns, but their manufacture is complicated and costly; this method of construction is therefore very little used. From the economic point of view, the preference goes to the structures which are obtained by gluing when flat and which are subsequently expanded. But in practice this method of procedure limits the structure to a substantially hexagonal form known as a honeycomb. In addition, the expansion reduces the width with respect to that of the initial block before expansion. Furthermore, the expansion does not take place in a uniform manner; it is more pronounced at the ends than at the centre, and the structure tends to have a concave profile along its longitudinal edges.
- the present invention has for its object a structure of the kind consisting of bands or sheets which are glued and subsequently expanded, which not only avoids these disadvantages while keeping the manufacture simple and cheap, but after expansion provides panels having a width which is at least twice that of the original block.
- This structure is characterised in that it is composed of bands having alternating folds in the shape of two Zs joined back to back and glued to each other on the lower and upper faces of the folds.
- Double folds are understood to mean folds of the type commonly referred to as box pleats, in which the band comprises alternately a fold in one direction and a fold in the other direction.
- this double pleat two equal lengths of the band are coupled together by a smaller element, the length of which is at least equal to half the length of the band; the successive bands are superimposed with a respective shift corresponding to this half-length.
- the gluing is effected by two lengths arranged one on the other, having in practice a displacement or shift of one band by one half-length with respect to the adjacent band, or by supplying from two different folding machines.
- the structure thus formed is expanded by a tractive pull on its opposite edges.
- the maximum expansion in a given direction gives rise to a unit having square or rectangular cells, the sides of which are displaced by one row with respect to the next.
- This manufacturing process may be carried out in a continuous manner.
- the machines which are usually employed for folding textile fabrics may be used.
- the gluing and the subsequent cutting-out operation are carried out by the usual means.
- FIG. 1 is a view of the structure before expansion.
- FIG. 2 shows the structure normally expanded.
- FIG. 3 shows a further method of expansion.
- FIG. 4 is a view illustrating the method of construction.
- FIG. 5 is a diagrammatic view of the manufacturing process.
- the structure in accordance with the invention is formed by a succession of glued bands.
- Each band has a double fold, that is to say, comprising: a portion 10 having a length a, two portions 11 having a shorter length, folded back on the portion 10 and attached to a portion 12 having a length a, which is itself coupled to the next portion 10 by a fold 11.
- the bands thus folded are placed side by side, and the portion 10 of one band is glued to the portion 12 of the preceding band.
- the assembly of the glued bands together thus cornprises incipent cells, each in the form of an irregular convex hexagon, each hexagon having the portions 1012 as its long opposite sides, and the folds 11 as its small lateral sides.
- the portions 11 may be more or less pronounced. It is on the length of these portions that the final expansion of the structure depends.
- These portions 11 are preferably given a length which is substantially equal to half the length a of the portions 10 and 12.
- the structure which has just been described may be made of any material: cardboard, paper (whether impregnated or not), metal, plastic material, etc.
- the gluing operation may be carried out by using any of the usual adhesives, or alternatively by a thermo-plastic effect. If the material used is a metal, the joint may be effected by welding or brazing.
- the structure in its expanded form is used as a filling or lining for all uses that may be desired. It may be associated with coverings of all materials: plywood, metal, plaster, plaster-board (known as Placoplatre), asbestoscement, etc., so as to form panels, partitions or other constructional members.
- a structure of this kind has excellent properties of strength, and especially of a uniformstrengthat all its points, by reason of the regular and intersected alignment of the square cells.
- the length of the portions 11 should preferably be chosen so as to be equal to half the length of the portions or 12. In this Way, the two foldsll are folded back on 12 so as completely to overlap the necessary portions 12.
- a coating 23 of adhesive (and especially of glue), is laid on the band thus folded, and a further identical band is laid on to the glue.
- This second hand is however displaced or reversed with respect to the first, so that its portions 10 are glued to the portions 12 of the preceding band 20.
- the band 20' is then coated with glue at 23' in order to receive a further band 20" and so on.
- the sheet 24 passes between the blades 28-29 (which are suitably spaced apart) to which are given motions adapted to form double folds as shown at 30.
- the sheet 30 thus folded receives a coating of glue from the roller 31. It is then cut-off transversely into elements of suitable length and these elements fall into a central passage in which they are superimposed one on the other with the required displacement, and are glued to each other at 32.
- a cellular structure comprising a plurality of strips each having a plurality of elongated sides of equal length in one plane, a plurality of further elongated sides of the same equal length as said elongated sides in another plane parallelly spaced from said one plane, angular sides which are half the length of said elongated sides connecting one end of each of said elongated sides with an adjacent end of said further elongated sides to form box pleats, each strip of box pleats placed adjacent a Succeeding strip of box pleats such that said elongated-sides of each strip are attached throughout their entire area to said further elongated sides of an adjacent strip thereby forming a-plurality of flexible areas in said structure consisting of an elongated side of one strip, a coextensive further elongated side of an adjacent strip, and their respective angular sides, and said structure being expansible simultaneously in two directions atright angles to each other through triangular rectangular, and hexagonal afirst series of straight sides of equal
- each element capable of being flattened so that each angular side has one surface in contact with the inner surface of the side of said first series of straight sides to which it is connected and the other surface in contact with the inner surface of the side of said second series of straight sides to which it is connected, the sidesof each of said first series of straight sides connected substantially throughout their entire area to the adjacent sides of said second series of straight sides, and said structure being expansible simultaneously in two different directions at right angles to each other to a hexagonal configuration.
