PROCESS FOR THE MANUFACTURING OF BUNDLES OF STEEL WIRE PIECES
.'.. ::'"',,'. ..:
The ;nvention relates to a process for the manufacturing of bundles of steel wire pieces for the strengthening o~
building elements, such as beams or roadway surfaces. In order to come into consideration for that purpose, the wire pieces shall have an essentially oblon~ form, with a thickness of 0.3 to 1.5 mm, a length-to-thickness ratio , between 40 and 120, and a maximal length of 120 mm. By "oblong" is meant, that the wire piece is not so bent or ~ ~ -curled, that it would no longer be possible to distinguish a general length direction in which the wire piece has to exert its strengthening effect. In this respect, the apparent length of the wire piece, i.e. the distance between both ends of the wire piece, has not to be smaller than 0.7 times the --length, as measured along the wire piece. The thickness of the wire piece, for non-circular cross-sections, is ~ ;r -calculated as the diameter of the circle having the same area.
Such steel wire pieces are used for the reinforcement of cementitious concrete, and are mixed into the wet mixture, ;
that is dumped thereafter, deformed and compacted and then hardens in the desired form. When these wire pieces are dumped into the mixture, without any further precaution, then this leads to the conglomeration of the wire pieces into balls, instead of an equal distribution in the concrete. For that reason, those steel wire pieces are introduced into the wet mixture in the form of bundles of such steel wire pieces, that are held together in a bundle by means of a binding substance that loses its binding power during mixing, more specifically by the fact that the binding substance dissolves, totally or partially, in the water of the cementitious mortar or concrete.

Applying the glue in a molten form has the advantage that the ;~ i~
glue must no longer be dried in a drying furnace, but that it can solidify by simply rapid cooling, before the bundle is transversally cut into pieces. In this way the production speed can be raised and drying energy saved. And the method - ~ - - .

It is an object of the present invention to provide an alternative for this method, whereby more or less advantages can be obtained in dependence on the circumstances, such as the intended use.
The invention is based on the finding that the glueing substance, although known as a substance that has to be totally or partially soluble in water, mustnot for that reason necessarily be applied in the form of an emulsion or solution in water, but can also be applied in the form of a hot molten liquid. This can even be applicable for substances that mustnot be soluble in water at all, but that are adapted to disintegrate by melting.

Applying the glue in a molten form has the advantage that the ;~ i~
glue must no longer be dried in a drying furnace, but that it can solidify by simply rapid cooling, before the bundle is transversally cut into pieces. In this way the production speed can be raised and drying energy saved. And the method - ~ - - .

of applying a molten glue doesnot prevent to use a glue that still is totally or partially soluble in water, in such a way -~
that the bundles of wire pieces are usable both in cold cementitious mortar or concrete and in hot bituminoùs concrete. A further advantage in the manufacturing lies in the fact that a glue to apply by melting takes much less room for storage, and can be preserved undefinitely in time.
The invention is consequently characterized by the fact that glueing occurs by means of a glue in molten state, and that this glue solidifies thereafter by cooling down. `~~
The glue in a "molten state" is to be understood here in the sense that the glue, under influence of temperature, has lost -its solidity, not necessarily completely by heating above a sharply defined melting point that the glue should have, but that it has lost sufficient solidity to be applied to the wire bundle. For substances that are composed of different molecules with different melting points, as e.g. for synthetic resins, the loss of solidity occurs by gradually softening through a softening temperature range, and it is sufficient that the substance is sufficiently soft to be applied as a ylue. For such substances the temperature level of softening is determined here by the softening point ~ -according to the Ring & Ball Test. And for the substances with sharply defined melting point, the "softening" occurs at the melting point. This is what is meant hereinafter by ~b softeni~g point.
- .
When the fibre bundles are intended for use in bituminous concrete, a glue will be chosen that is adapted to disintegrate by ~elting when mixed into such hot bituminous concrete. This means then that the glue, under influence of temperature, loses sufficient solidity to allow the bundles `~
`.` ~ ~ `.,:
2~298 .- ~
of wire pieces to disintegrate into indiv;dual w;re pieces under the mixing movement, where this loss of solidity is due to the substance passing wholly or partially from the sol;d into the molten state. As the mixing temperature of ~ ~-bituminous concrete ranges from about 80C to 200C, and as the mixing temperature has preferably to be 30 to 50 degrees ;` i centigrade above the softening point, a glue will be chosen having a soften;ng point in the range between 50C and 170C.
Below 50C, the risk increases indeed, that the bundles begin to st;ck to each other when exposed to the sun or to warm climate circumstances.
As a glueing substance, a bitumen can be chosen preferably of the same composit;on as used in the bituminous concrete, if the fibre bundles are intended for mixing into such bituminous concrete. As known, a bitumen is a mixture of ma;nly hydrocarbons with residual ;mpur;ties, as obtained as residues from ref;ning coal or petroleum, such as p;tch or tar or asphalt. They are hard at room temperature and suffic;ently liquid at the m;xing temperature to flow between the other components of the bitum;nous concrete (that further comprises a mixture of filling material, such as sand, lime, and/or stone pieces of a dimension of 2 mm up to 20 ~m) and to form, after hardening, the binding component for the bituminous concrete. ``
It is also poss;ble, for the glueing substance, to use a ;~
thermoplastic polymer or copolymer, preferably in the form of a conventional hot melt glue, which, depend;ng from one manufacturer to the other, also comp~ises res;ns, waxes, softeners, stab;l;zers and possibly f;llers, ;n addition.
Accordingly, a polyester-polyurethane glue can be used, e.g.
according to U.S. Patent No. 2.801.648, of which the softening point can be set by adding less or more ' ' '.: ' " " '.
di-isocyanate during the manufacturing of the glue. An EVA-glue (ethylene-vinylacetate copolymer) can also be used, of which the softening point can be adapted by means of the proportion ethylene/v; nyl acetate. When a hot melt glue is necessary that can dissolve or emulgate in water, then a typical hot melt glue can be taken, as used for applying in molten state to paper or cardboard, where the glue can therafter become tacky again by moistening with water. In practice, a choice can be made among the different hot melt glues available on the market, and that are e.g. des~ribed in the book of D.L. BATEMAN "Hot melt adhesives", Third Edition (Noyes Data Corporation).
The glue can be applied in di~ferent ways. It is possible to pass a bundle of wires continuously through a bath of molten glue, and to wipe off the excess of glue at the exit of the bath before cooling the bundle, e.g. in an air jet or in water, when a glue is used that is not soluble in water.
Another method, when the glue is in powder form, consists of ~ -heating up a continuous bundle of wires and passing this hot bundle through a fluidized bed of such powder. The powder then melts against the wire bundle, and the glue solidifies again at the exit of the fluidized bed. It is also possible to use conventinnal appliers with a nozzle that continuously delivers the molten glue under pressure on or around the bundle and a wiping piece. It is also possible to apply the glue on the individual wires first, and to bundle the wires thereafter, where the wires can be glued together, e.g. by heating up and cooling down again.
In order to glue the wire pieces easily together, and so that the wire pieces can easily be separated thereafter, it is ` `~
preferred to glue the wires side by side into a flat bundle.
It is however also possible to manufacture a round bundle, in .

" -~
which the glue doesnot completely penetrate towards the core of the bundle, but keeps all the wires together because it acts as a tight sleeve around the bundle. Glueing the w;res together does consequently not necessarily mean that all wire pieces are brought in contact with the glue, but only that, after solidification of the glue, the wires are kept together -into a bundle.
When the wires are conducted side by side in order to be grouped into one flat bundle in one plane, and when the wire pieces are to be provided with undulations or deformations and/or hooks or bendings at the extremities, those deformations shall preferably be applied on the continuous bundle, before the cutting thereof. This is then preferably done by conducting the flat bundle continuously between two rotating rollers with undulating cross-sectional circumference or with another profile, where the protrusions of one profile match the indentations of the other one. In such a way, deformations are applied in a plane that comprises the longitudinal direction of the bundle, and that is perpendicular to the plane of this bundle. g : . ~ , .
It is clear that the process is very adapted for a continuous -~-~
process, in which a number of wires are unwound from their respective spools, and in which these wires after unwinding are caused to converge towards the entrance of a machine, in which they are bundled and glued. In this machine, the bundle ;~
passes a glueing station first, where the glue is applied, and then passes a cooling station, where the glue is caused `~
to cool down for solidification, and then further optionally passes a deforming station, where the bundle is deformed between two rotating wheels, and finally passes a cutting station, where the bundle is cut into pieces, and the bundles of wire pieces are collected in a container. ";--` ;
