As stated above, the improved product consists of one Plastic film or a laminate with in the or

the same arranged reinforcing wires; but it can also look a coated or uncoated corrugated wire mesh with plastic layers exist on one or both sides of the same. A method and an apparatus for forming reinforced plastic sheet according to the invention shown in Figs. 1 and 1A-C. While the resulting product that of the device in FIG. 1 and that of that in FIGS. 2, 4, 5 and 6 the devices shown are useful for many purposes, It will be shown that these products also help in the formation of other types of reinforced products according to the invention for construction, packaging and others Applications can be used beneficially.

Reference is now made to Fig. 1, which shows an embodiment Invention for the production of a plastic laminate with embedded therein, shows longitudinal reinforcement wires. The device has more in detail a relatively large heated drum 10, on that of the first film 11 previously coated with a heat-sensitive adhesive may be fed from the roll 12 and around the roller 13. If desired, The roller 13 can also be heated to the temperature of the film 11 just before its engagement with the drum 10 to increase. Immediately after application of the film 11 on the drum 10 is a plurality of wires 14 of a plurality of rolls 15 to the. Rollers 15 and 16 and on the drum 10 as well as in superimposing Relation to the film 11 supplied. The roller 16 is preferably with a plurality of annular, spaced-apart wire-receiving grooves for Maintaining the desired wire spacing. The roller 15, which the Giving wires the spacing at the beginning is described in more detail in connection with FIG. 3.

A second film 17 previously coated with a heat sensitive adhesive can be covered, is from a roller 18 and around the roller 19 in superimposing Relation to the wires 14 supplied. The laminate is then continued around the drum 10 out and the same supplied sufficient heat so that the two films with the wires located between them can be sealed together. The temperature of the drum 10 is of course related to the speed, so that adequate heat is transferred to the plastic films. For example can, when the drum 10 rotates at a relatively high speed, the temperature of the drum at or even above the melting point of the plastic film 11 lie. On the other hand, it would, should the drum be at a slow speed operated will be necessary, the temperature of the drum slightly below the melting point of film 11.

The two films are sealed together by a pressure roller 20, which is preferably covered with a thin layer of polytetrafluoroethylene to each to prevent possible sticking of the film to the pressure roller. The coating of the roller 20 is designated by the reference numeral 20 'and roller 20 is preferred cooled by intervention with a chill roll 21, since it is important that the surface of the roller is kept at a temperature which is a good deal below the melting point of the plastic and preferably below the embossing temperature lies. The roller 20 also acts to remove the finished laminate from the roller 10, whereupon it is fed to the cooling rollers 22 and 23 and subsequently is wound on a roll 24. 1A shows a longitudinal section through the laminate prior to sealing the films 11 and 17 together. Fig. 1B shows a transverse view of the laminate prior to sealing the layers, while Fig. 1C is a transverse view is that the two layers sealed together with those arranged in them Wires 14 shows. In actual practice, the thickness of each of the films is usually about half the thickness of the wires, and a more accurate representation of the product is given in Fig. 1B 'and 1C' in section.

From the description of the device in Fig. 1 it is clear that, when using a single film like film 11 and wires 14 only in the surface of the same to be embedded, the wires with a primer "primer" such as sodium silicate or with a very thin layer of a suitable one Plastic can be coated to prevent the wire from sticking to the Movie 11 to make it easier. In such a case, the wires would, whether they be a primer and have the plastic coating or only the plastic coating itself on which Surface of the film 11 as shown in Fig. 1, and thereafter would the pressure roller 20 pushes the wires into the surface of the film.

When feeding the wires 14 into an overlapping relationship with the Film 11 may be desired or necessary to have a predetermined on the wires Maintain tension.

To this end. an auxiliary roller 16 'can be used, which against the grooved roller 16 rests, and by using a braking device on the Roller 16 'allows the tension on the wires to be precisely controlled.

A modified embodiment of the invention shown in FIG is shown in FIG. In these figures, the same components are given the same reference symbols designated. In the embodiment of the invention shown in FIG. 2, the film 11 from a roller 12 and from there onto a roller or drum 25 by means of an intermediate one Idler roller 26 supplied. An adhesive contained in a trough 27 is by means of Applicator rollers 28 and 29 applied to the outer surface of the film 11, after which the coated film passes through a drying device 30 which is in the form of an electric Radiator or else a housing with an inlet 31 and an outlet 32 to direct hot air through the housing and over the surface of the film can. The dried film is then fed to drum 10 around rollers 33 and 34. Otherwise, the operation is the same as in Fig. 1 except that the temperature of the roller 10 can be changed so that it has the heat sensitive adhesive heated appropriately to create a seal between to create films 11 and 17. If desired, the film 17 may be similar Way as the film 11 are coated so that the mating surfaces of both Films are coated with heat sensitive material to form a seal to facilitate between them.

Figure 2A shows the initial relationship of wires 14, that of adhesive coated layer 11 and the uncoated layer 17. Fig. 2B is a cross-sectional view 2A, while FIG. 2C shows the finished structure with the adhesive 11 'between the two Layers shows.

It is clear that a wide range of different plastics for forming the foils 11 and. 17 can be used and that the selection of the specific Plastic would then largely depend on the end use of the product.

For example, it may be desirable to have films with different properties and different colors. to use for decorative purposes, and the films can be either thermoplastic or curable. When an essential strength is desired is, especially if the product is at high temperature or constructive Applications should be used, a curable plastic is desirable. This curable plastic would of course have a thermoplastic stage and then ultimately take on a hardening stage in the end product. It is also it is clear that the plastic layers are essential for certain applications May have flexibility, while in other forms of application relatively rigid plastics can be used.

When creating a product for specific application in the Packaging industry are plastics such as polyethylene, polystyrene, polyethylene higher Density, polypropylene and the polyamides and polyesters probably the more desirable Plastics that can be used.

While the wires 14 on the drum 10 in any suitable Way is one embodiment of a device that can be used to this Purpose can be used, shown in Fig. 3. In this figure is the roller 15, which leads the wires onto the roller 16, with a large number of closely spaced spaced apart disks 35 provided, which the distance between the wires 14 upheld. The wires are fed from a plurality of rollers 15 'over a Series of guides 36 are fed which hold the wires between the discs on the roller 15 lead. With this arrangement the 'roller 16' would have a resilient surface and against the wires 14 while it is on the reel 16, issue. With such an arrangement the voltage would be effectively controlled, and it would not be necessary to focus solely on the friction of the wires to leave with the roller 16 to control the tension.

Fig. 4 shows a further modification of the invention in which a plastic directly on a drum and in contact with a multitude of lengthways arranged reinforcing elements such as wires is extruded. In this embodiment the invention, the drum 37 is preferably by the circulation of water or another suitable coolant cooled therethrough, and one A plurality of wires 14 is fed from a plurality of rollers 15 ′ over the roller 16 fed onto the surface of the drum 37. The drum 37 can one Have a plurality of fine grooves for receiving the wires 14 or not have. In most cases, however, it would not be necessary to grooved the drum provided that adequate tension is maintained on the wires will. Immediately after the wires are fed onto the drum 37, it becomes a plastic 38 is extruded onto the drum through an extruder 39, which is preferably an extruder can be with a straight line-shaped spray head. Since the on the surface the drum of extruded plastic is at a very high temperature it surround the wires as shown in Fig. 4A and then gradually cool down until he reaches the take-off roller 40. The roller 40 is used for the purpose of reducing the Temperature on the film cooled so that it is guided around the roller 41 and then can be wound on the roll 42. The finished product is shown in Figure 4B and is then either for further processing or for direct use for the desired purpose ready.

The embodiment of the invention shown in Fig. 4B is essential identical to the product described above in connection with FIG a single film 11 is used and the wires 14 in the surface of the Films can be embedded. It is also clear that the wires 14 are connected with Fig. 4 can either be coated or not coated, depending on how this is desired.

Another embodiment of the invention is shown in FIG. In this embodiment of the invention, a film 43 which is previously perforated may be fed from a roller 44 around a roller 45 onto a drum 46. Direct after the film 43 has been applied, a plurality of wires 47 are drawn from the rollers 15 ', around rollers 48 and 48 'and onto the surface of the perforated film 43. The rollers 48 and 48 ′ essentially correspond to the rollers 15 and 16 in FIG. 1.

A second imperforate film 49 is taken from a roll 50 µm a roller 51 and in an overlying relationship with those arranged in the longitudinal direction Wires 43 supplied. The structure of the product at this point in the process is shown in Fig. 5A showing the relationship of films 43 and 49 to those between them arranged wires 47 shows. The perforations in the film 43 are denoted by the reference numeral 43 '. Fig.

5B is a cross-sectional view of FIG. 5A.

The laminate designated by reference numeral 53 then moves between radiators 52 and down around a roller 54 over their entire surface Vacuum openings are distributed and also through the circulation of the coolant is cooled through the same. The specific structure of the roller 54 is well known in the art.

The heat imparted to the laminate 53 by the heating elements 52 is sufficient in order to produce a corresponding seal between the films 43 and 49 with the wires placed between them. If desired, can be a pressure roller 55 with the roller 54 to ensure a corresponding Sealing to be coordinated. Films 43 and 49 with those interposed between them Wires 47 are then further cooled by roller 56, whereupon they are moved by one Roller 57 are fed and wound onto the roll 58. The resulting product is shown in cross section in Fig. 5C, although in actual practice the The thickness of the combined plastic layers does not exceed the thickness of the wires allowed.

The embodiment of the invention shown in Fig. 6 is essentially identical to that shown in FIG. 5 with the exception that one of the plastic films with a heat sensitive adhesive before coating with the other layer overdrawn will. Accordingly, the same reference numerals are used in these two figures Designation of the same components used. In this embodiment of the invention the film 43 is first placed on the roller 46 on that described in connection with FIG Kind of fed, after which the longitudinal wires are in an overlapping relationship fed to the film. The film 49 is fed by a roller 50 around the rollers 59 and 60 and thence fed onto the drum 61. An adhesive contained in the tub 62 is applied to the surface of the film 49 by rollers 63 and 64, whereupon the film then runs around the roller 61 ~ and from a radiant heater 65 and / or hot air dried as desired. Then the coated film leaves the roller 61 and is around roller 50 and on roller 46 in overlying relationship with the Wires fed to produce a starting laminate, denoted by the reference number 53 and shown in cross section in FIGS. 6A and 6B. The prelaminate passes between the heaters 52-52 and from there around the cooled vacuum roll 54, which, due to the perforation of the film 43, causes the two films to stick to one another causes. As far as the heat sensitive adhesive is used, the The temperature of the films need not be so high to effect a seal as in the case of the device shown in Fig. 5 with the result that one of the Films, namely film 49, would be easily deformed to fit tightly around the wires 47 as shown in Fig. 6C. In this figure is the glue denoted by the reference numeral 49 '. To create a more effective seal, A pressure roller 55 may be used in conjunction with roller 54 if desired will; in such a case the resulting product would be almost as shown in Fig. 5C of the drawings. In Figs. 6A to C, the thicknesses of the Film has been enlarged for the purpose of better understanding.

In the previous exemplary embodiments of the invention a laminate using a plurality of longitudinally extending wires with a Layer of plastic on either one or both sides of the wires, as the case may be the specific requirements. It is clear, however, that in the foregoing Embodiments of the invention, if desired, with one of the films beforehand Wires can be formed extending transversely therefrom, so that there are both transverse and longitudinal wires in the resulting product be arranged and thus in reality one enclosed in a plastic Would form lattices. It will also be understood that different sizes of wire and different ones Thicknesses and types of plastics depending on the purpose of the themselves resulting product can be used.

Figures 7 and 8 show two embodiments of the invention for manufacture resulting products with both longitudinal and transverse, in plastic films embedded wires. While any number of types of procedures in the formation of a Plastic o2 with transverse wires inside can be used a suitable type of procedure involves the use of a product as shown in Fig. 1C, 1C ', 2C, 4B, 5C or 6C, and cutting the same to lengths equivalent to the width of the film. Each separate section will rotate 0 by 90, and then consecutive of these sections will go through attach a heat seal or other suitable device to one another; to create an elongated roll of film with wires running across the film extend. Such a construction can be used in connection with FIG will.

The apparatus in Fig. 7 has a drum 69 with over the surface the same distributed vacuum openings and a device for the circulation of a suitable fluids therethrough for controlling the temperature of the drum on. This is desirable in that there are heating means around the drum as described are provided to raise the temperature of the films for lamination purposes. A first film, indicated by reference numeral 70, is fed from a roll 71 µm a roller 72 and fed onto the drum 69. After that, a variety of longitudinal Wires 73 from a plurality of rollers 15 'around rollers 74 and 75 in an overlying one Relation to the film 70 supplied. Rollers 74 and 75 are essentially the same the rollers 15 and 16 in Fig. 1. A perforating drum 76 with a plurality of spines extending from these perforate the film 70 so that the inside of the drum 69, vacuum created a tight adhesion of the film to the surface of the Drum effects. The film 70 then runs along with the wires 73 under the radiator 77 through which the temperature of the film and wires to a point close to Raises the melting point of the film. A second film 78 is from a roll 79 and around the roller 80 in an overlying relationship with the wires 73 and thence on that Heater 81 supplied over, which gives heat to the outer film and the same raises to a temperature sufficient to seal it with the first film 70 is required.

One or the other of films 71 and 78 contains transverse wires, and the film can be made in a manner described above. That heated structure then runs between the nip of the drum 69 and the roller 82 through to effect the seal between the two films, and the Sealed films then pass around roller 82 and then around the Rollers 83 and 84. The rollers 82 to 84 also effect the cooling of the laminate, see above that the resulting laminate 85 is rolled up on one roll or on a subsequent one Processing device can be brought. The resulting laminate is 85 shown in Figures 7A and 7B. In this case, the film 70 has a plurality of wires 70 'and the wires 73 are arranged between the film 70 and the film 78. A cross-sectional view of the structure shown in Fig. 7A is shown in Fig. 7B. Figure 7C is similar to Figure 7B and shows in greater detail the relative thicknesses of the plastic layers and the wires.

The construction shown in Fig. 8 differs from that shown in Fig. 7 by using an adhesive to seal the two To attach plastic sheets to each other.

In this embodiment of the invention, a drum 69 is used, which is essentially identical to that described in connection with FIG. 7, and the first film 70 is fed from a roll 71 and around the roller 72 onto the drum 69 supplied. Then a plurality of wires 73 from a plurality of reels 15 'and fed around rollers 74 and 75 in overlying relationship with film 70. The wires 73 and the film 70 are then fed below the heater 77, to bring the film and wires up to a sealing temperature. Of the Film 78 is fed from a roll 79 around a roller 80 and onto a drum 86, which has a heater 87 disposed around a portion of its circumference. An adhesive contained in the trough 88 is applied by means of rollers 89 and 90 to the outer surface of the film 78 is fed, and the coated film is then removed from the heater 87 dried and fed onto the drum 69 in overlying relationship with the wires 73. To make the seal between the two films with the one placed between them Wires 73, the laminate on the drum 69 is further enhanced by the heating element 81 Bestowed warmth. As in the case of Fig. 7, one or the other contains the films 70 and 78 preferably have transverse wires so that the resulting structure has both longitudinal and transverse wires that actually insert a into the Plastic laminate form an embedded grid. The finished laminate then circulates the rollers 82, 83 and 84, which are preferably cooled, so that the resulting Laminate 85 'for further processing or storage, depending on the circumstances, ready.

If desired, the roller 82 can with the laminate as it passes the same between this roller and the drum 69 in both Fig. 7 and in Fig. 8 are in pressure engagement to evenly seal the layers to ensure.

The resulting formation 85 t is shown and included in FIG. 8A the film 70 with wires 70 'arranged in it, an adhesive layer 78' and a lower plastic layer 78. The wires 73 are of course 'between the Layers arranged. Figure 8B is a cross-sectional view of Figure 8A.

Fig. 9 shows an embodiment of the invention for manufacture a reinforced corrugated laminate used for the formation of cardboard boxes and the like Packaging of objects and for construction elements can be used. The resulting structure essentially includes a corrugated section overlying layers on one or both sides of the same. The wavy one Section is preferably reinforced with transverse wires, although lengthways as well Wires can be used, and the overlying layers can, depending on the given circumstances, in a similar manner by longitudinal or transverse wires or a combination of longitudinal and transverse wires are reinforced.

In this embodiment of the invention, the first, preferably Plastic film 91 previously coated with an adhesive from a roll 92 around a Roller 93 and fed onto a drum 94. The drum 94 can be temperature controlled be to the film 91 to raise its temperature near the melting point To give warmth. The film 91 may of course contain transverse wires, as described above in connection with the exemplary embodiments illustrated in FIGS. 7 and 8 of the invention or it can be a non-reinforced film. Thereafter becomes a plurality of longitudinal wires 95 from a plurality of reels 15 'and around rollers 96 and 97 (rollers 15 and 16 in FIG. 1) onto drum 94 in superimposed relation to the film 91 fed in much the same way, as described in connection with FIG. 1 and FIG. 3, respectively. A second film 98 is rolled by a roller 99 around the roller 100 and onto the drum 94 in superimposition Relation to the wires 95 supplied. The film 98 may or may not be longitudinal Reinforcement wires as described in connection with film 91 may be provided has been.

The laminate is then moved downwards over a heater 101 and supplied to corrugating rollers 104 and 105 around rollers 102 and 103. if the film 91 is perforated in the same manner as that in Figs 8 shown embodiment of the device has been described, or if the If film is pre-perforated, roller 102 would then be provided with a variety of vacuum ports be provided in its surface, with a suitable vacuum device with the #openings are connected in a manner known per se, and the seal would then be done on the vacuum roll.

On the other hand, if the film 91 is imperforate, the rollers could 102 and 103 must be positioned in close proximity to one another in order to achieve a sufficient Provide pressure to effect a satisfactory seal.

In either case, however, the roller 103 is preferably cooled in order to Temperature of the finished laminate prior to attack by corrugating rollers 104 and 105 lower.

The resulting laminate, designated by reference numeral 106 is then runs downwards over a radiator 107 in order to turn at least the To raise the surface layers of the corrugated structure to the sealing temperature. A third film 108, the reinforcement wires, preferably previously coated with an adhesive may or may not contain, is taken from a roller 109 and around the reels 110 and 111, the latter being heated to apply the adhesive to the Bring the surface of the film 108 to a sealing temperature. The warmed Film 108 is then fed around a roller 112 which can also be heated, and then brought into surface contact with the corrugated structure 106. A fourth, and preferably pre-coated, film 113 similar to film 108 is, is from a roller 114 and around the rollers 115, 116 and 117 in an overlapping Relation to the other side of the corrugated structure 106 supplied. The roller 116 is heated in the same manner as described in connection with the roller 111 has been, and the roller 117 can, if desired> also be heated, to keep the temperature of the film 113 at the sealing temperature as in the case of the Hold film 108.

The corrugated structure 106 is together with the overlying layers 108 and 113 fed between a pair of cooling belts 118 and 119, the Belts 118 from chilled rolls 120 and 121 and belts 119 from chilled rolls 122 and 123 are worn. The bands 118 and 119 are in sufficient close proximity to each other to apply pressure to the laminate to ensure the seal of the overlying layers with the corrugated structure 106 without a substantial one To apply deformation of the same. The resulting structure is denoted by the reference number 124 and for further processing or. Ready to use.

A cross-sectional view of the corrugated structure 106 is shown in FIG.

9A, in which the plastic layers for the sake of convenience Understanding were increased in thickness. It can be seen that the film 91 transverse wires 91 ', longitudinal wires 95 and the plastic layer 98 contains.

The final structure 124 shown in FIG. 9B has the corrugated Partial structure 106 with longitudinal and transverse wires and a pair of overlying Plastic layers 108 and 113. A modified embodiment of the invention is shown in cross section in FIG. 9C and denoted by the reference symbol 124 ′. In this embodiment of the invention, the structure 106, as in the case of FIG. 9B overlying layers 108 and 113, but also transverse reinforcing wires 108 'and 113'. It goes without saying that the overlying Layers 108 and 113 also include both longitudinal and transverse reinforcement wires as shown, for example, in Fig. 13E, below is described.

The embodiment of the invention shown in Fig. 10 is the 9, and like components are used to denote like components Reference numerals used. The type of formation of the corrugated, laminated, reinforced Form 106 is essentially the same as that shown in connection with FIG and described identical. However, the overlying layers become immediate coated with an adhesive prior to application to the corrugated structure. In particular film 125 becomes from roll 126 around rollers 127 and 128 and up from there fed through an oven 129. A trough 130 contains an adhesive that passes through a roller 131 is applied to the film 125. The adhesive-coated film 125 is dried in oven 129 and then around the. Rollers .132 and 133 are fed and brought into contact with one side of the corrugated structure 106. The device for applying the second film 134 to the other side of the corrugated structure 106 is identical to that described above and the same to denote it Components are provided with the same reference numerals provided with a handle. The wavy Formation 106 is down between the two films 125 and 134 Cooling rollers 135, 135 'and 136, 136' fed to cool the structure and a ensure good adhesion of the outer layers. The resulting structure is designated by the reference numeral 137 and shown in cross section in FIG. 10A.

The corrugated structure 106 in this figure is similar to that shown in Fig. 9A identical and has outer layers 125 and 134 attached to the corrugated Formations are attached by adhesive layers 125 'and 134'. The outer layers As shown in FIG. 10B, 125 and 134 may include reinforcement wires that are shown in FIG of this figure with the reference number 138 in the layer 125 and with the reference number 139 in the layer 134 are designated. Longitudinal reinforcement wires are used also preferably included in the outer layers, how can be seen from FIG. 13E to be described.

The preceding embodiments of the invention such as that in Fig. 1 and 4 through 10 can be used to use a wire mesh instead of the longitudinal Wires are prepared; in this case it would not be necessary to have a plastic layer with transverse wires embedded in the same. For example films 91 and 98 in Figure 9 do not require transverse wires as a wire mesh between the films instead of the bare longitudinal wires 95 could. An improved method and apparatus for manufacturing related thereto such a grid are shown in FIG.

In Fig. 11, a designated generally by the reference numeral 140 is used transversely corrugated ribbon carried by a pair of drums, only one of which is shown and denoted by reference numeral 141. To make wires in predetermined lengths cutting and feeding them one by one to the troughs of the belt 140 are suitable devices intended. The wires identified by the reference numeral 142 are on the top of the belt and moving towards the drum 141. A multitude of narrow belts 143 carried by sets of rollers 144, 145 and 146 holds the Wires 142 on the corrugated belt 140 while it is around the left side of the drum 141 runs downward, into position as shown in FIG. Once everyone When the wire reaches the lowest section, it is unloaded onto a drum has a plurality of axially aligned hooks 148 disposed about its circumference. As each of the wires 142 is unloaded onto the drum 147, it becomes one of the The elastic set is gripped and thus held in position while the drum 147 turns. A set of lengthways Wires that are designated by the reference numeral 149, is of a plurality of rollers 15 ' supplied in much the same way as described in connection with FIG became. These wires are wrapped around rollers 150 and 151 which line rollers 15 and 16 in Fig. 1 correspond to, fed and run between the nip of that roller and a second roller 152 therethrough. The roller 152 is preferably grooved to the Maintaining proper spacing between each of the plurality of Wires 149 to ensure. The wires 149 then run under the heater 153 through and around the roller 154, the surface of which is an elastic layer 155 and in which a plurality of grooves are preferably formed in order to to release the axial rows of hooks 148 carried by the roller 147.

The wires 149 run around the surface of the outer layer 155 of roller 154 and are in tight engagement with each of the transverse Wires 142 urged to form a grid. In the preferred embodiment however, the wires 149 are covered with a heat sensitive adhesive or plastic coated, which ensures a firm connection between the two sets of wires. The connected wires, which now form a grid, are entrained around the roller 147 and guided by roller 156 onto roller 157.

It is of course desirable that the drum 147 be cooled in order to to quickly lower the temperature of the wires after they have been joined. One Cross-sectional view of the resulting grid is shown in FIG. 11A, in FIG which is shown how the longitudinal wires 149 the transverse wires 142 seize. If both wire sets with a plastic or suitable adhesive of the heat-sensitive kind were previously covered, so relieved this is the formation of a structure in which the wire mesh is corrugated and then the overlying layers are applied, as now in connection with Fig. 12 will be described.

In Fig. 12, a wire mesh denoted by reference numeral 158 is shown fed from a roller 159 and around a roller 160 to the corrugated rollers 161 and 162. The corrugated grid, now designated by the reference numeral 158 ', is over a Radiator 163 and thence down between a pair of straps 164 and 165 fed. The belt 164 is carried by a pair of rollers 166 and 167 while the belt 165 is carried by a pair of rollers 168 and 169. The rollers 166 to 169 are preferably cooled to maintain the tapes at a temperature that well below the melting point or the embossing temperature of the Surface of the corrugated structure to be applied films lies.

A first plastic film 170 is wound from a roll 171 around the roller 172 and on the outside of the belt 164 as it runs around the roller 166, fed. A second film 173 is rolled from a roll 174 around roller 175 and on the tape 165 as it passes around the top of the roller 168 is fed.

Since the wires in the radiator 163 at a relatively high They impart temperature to the films while they are engaged with the wires being pushed through rollers 166 and 168, sufficient heat. At the same time, the rollers acting across belts 164 and 165 hold the films 170 and 173 in tight engagement with the corrugated grid, while the whole structure is cooled. The resulting structure, denoted by the reference numeral 176 is shown in Figure 12A. The corrugated grid is identified by the reference numeral 158 ' and it can be seen that the outer portions of it are in the outer plastic layers 170 and 173 are embedded. If a wire mesh Is used in most cases it is desirable use coated wires to protect the metal against corrosion.

Another modification of the invention is shown in FIG shows a method and apparatus for continuously producing a corrugated Structure in which a reinforced, corrugated layer is created first and then the overlying layers are applied one after the other. In this figure becomes a plurality of longitudinal wires 180 from a plurality of reels 15 'and around rollers 181 and 182 (which correspond to rollers 15 and 16 in Figure 1) fed to a cooling drum 183, which by the circulation of water or another liquid coolant can be cooled in a manner known per se. Direct After applying the wires, a plastic layer is passed through an extruder 184 applied to the drum 183. After that, a plastic sheet or film is used 185 from a roller 186 and around a roller 187 in an overlying relationship to it the extruded layer 188 is supplied.

In so far as the layer 188 is on a relatively high Temperature, it will enclose the wires 180, and since they are at least is at the normal sealing temperature, it will stick to the film 185, which is applied immediately after extrusion. Layer 185 is preferred a film positioned in the transverse direction for the purpose of combining it with Wires was previously treated in the manner described above. Figure 13A shows Figure 8 is a cross-sectional view of wires 180 immediately after overlaying layer 188 in Figure 8 Relationship to the wires extruded on the drum 183. Fig. 13B is a cross-sectional view of the structure after film 185 is applied to extruded layer 188. From this figure it can be seen that layer 185 has transverse wires 185 ' contains. The structure is shown in Figure 13B; it is formed on the drum 183, is then removed from a roller 189 and runs afterward through heater 190 and thence to a pair of corrugating rollers 191 and 192. The corrugated structure denoted by the reference numeral 193 revolves the rollers 194> 195 and 196 and is then placed on a second cooling drum 197 by means of fed to the roller 198. Before the formation 193 is applied to the drum 197 a second extruder 199 feeds a plastic layer 200 to the drum 197. While drum 197 is cooled in the same manner as drum 183 is cooled the plastic layer 200 is nonetheless at a relatively high level Temperature, and therefore when the corrugated structure 193 is applied it becomes this stick firmly to layer 200.

The resulting structure is shown in cross section in Figure 13C and is removed from the drum 197 by a roller 201 and then around the rollers 202 and 203 are fed onto the drum 204. Before applying the corrugated structure, on one side of which a plastic layer is applied, on the drum 204, a third extruder 205 applies a plastic layer 206 to the drum. This plastic layer forms a second overlying layer for the corrugated Structure.

Since the extruded layer 206 is at a high temperature, when the corrugated structure is applied, it will stick firmly to the structure, whereupon layer 206 from drum 204 in the same manner as the layers 188 and 200 is cooled by drums 183 and 197. Then the resulting Formation is removed from roller 207 and the end material is indicated by numeral 208 designated.

A cross-sectional view of the resulting structure 208 is shown in FIG. 13D showing the relative locations of the various layers including showing reinforcement wires in the corrugated structure. From the description above It is clear that reinforced layers as shown in FIGS. 7B and 7C and Fig. 8B are shown as outer layers in the formation of the corrugated structure by the device shown in FIG instead of the extruder 199 and 205 can be used. In such a case, they would be reinforced Layers are preheated before they are fed to drums 197 and 204, thus a corresponding heat to effect a seal with the corrugated Form 193 is delivered. The use of outer layers 209 and 210 in of the type shown in Figures 7B and 7C and 8B would be that shown in Figure 13E produce resulting structures. In the latter case, however, it is generally it is not necessary to use longitudinal wires in the corrugated structure, because the outer layers create a corresponding structural strength.

For the purpose of better understanding, the plastic layers are and the wires in Figures 13A through 13E have been shown exaggerated. Fig. 13E ' Figure 13E shows the product of Figure 13E, showing the relative thicknesses of the plastic layers and the wires are shown in more detail.

It is clear that the various products from which up until now the And which were manufactured in accordance with the invention, either on its own or in combination with the other types of packaging materials Can be used to meet a wide range of needs in the packaging industry correspond to. For example, the structure denoted by the reference symbol 85 in Fig. 7C, as shown in Fig. 14, with a generally denoted by the reference numeral 211 designated cellular material can be combined to form an essentially rigid one To create a wall that covers at least one side with the cushioning material is.

The cushioning material can have any suitable shape and material as shown and described in US Pat. No. 3,142,599. Fig. 15 shows a further modification of the invention, in which the layer 85 with a plastic foam 212 is combined, which is made of polyurethane or a other suitable Material. It goes without saying that while the reinforced plastic layers 85 have been shown in Figs. 14 and 15, similar combinations with those in Figs other reinforced layers shown above can be. Fig.

16 and 17 show additional products that are in accordance can be made with the invention. In Fig. 16 is that shown in Fig. 13E Structure combined with the cellular material 211, while in FIG. 17 the same Structure with a plastic foam 212 is combined. It is of course clear that the structure of Fig. 13D can be used instead of the structure of Fig. 13E, and even a structure as shown in Fig. 13C can be used, either in the manner shown or with longitudinal or transverse wires reinforced.

In all of the illustrated and described exemplary embodiments the invention it is clear that different types of materials in the respective manufacturing processes can be used. The reinforcing elements can be made of steel, for example exist, which has the desired carbon content, and there can be several Steel alloys as well as aluminum, copper and other similar metals are used that offer structural strength and rigidity. It can be light metals like magnesium or even tungsten can be used when weight is a significant factor. In connection with the plastic, polyethylene of various densities, polypropylene and their copolymers, polystyrenes and polyvinyl chloride can be used; even various polyesters and polyamides can be used. For different Applications can also be in thermosetting resins such as modified and flexible Phenolic resins, including phenol formaldehyde, urea formaldehyde, Furfuryl formaldehyde and melamine formaldehyde can be used. To provide resistance to moisture, To create steam and other gases, the plastic films can be beforehand with one Film made of polyvinylidene chloride or other relatively gas-impermeable plastics be coated. As mentioned above, the various are according to the invention manufactured products in most cases for the purpose of better understanding shown with excessively thick layers of plastic and adhesive. In in any case, however, the thickness of the plastic layers is usually approximately half the thickness of the reinforcement wires. It goes without saying that the Number of wires per inch (2.54 cm), the thickness of the wires and the thickness and type the plastic layers all together to achieve the desired structural strength can be changed. The arrangement of the reinforcement wires can be selected to achieve the desired purposes.

For example, it could be both longitudinal and transverse Wires are not used in the layers overlying the corrugated structure the longitudinal wires in the central corrugated structure may be necessary to use. The term "wires" as used in the present application is intended to Wires with various cross-sectional configurations such as round, oval, flat, square and the like.

While only certain embodiments of the invention are shown and have been described, it goes without saying that changes and Substitutions can be made without departing from the scope and spirit of the invention to deviate.
