Definitions
- the present invention relates to a machine for the continuous production of a strip of wire mesh welded using a single wire, as well as to a manufacturing process implemented using said machine, and finally to the wire mesh monofilament. got.
- the fences thus formed offer a wide variety of possible applications, in particular because of their decorative appearance, and can be used in gardens or public places, public and private houses and buildings, and in general in any type of construction. frequented by man.
- the meshes are generally produced by machines which use a plurality of longitudinal wires which are unwound and straightened in parallel, from several separate spools.
- the number of these coils is variable, and traditionally between eight and forty eight, depending on the dimensions of the trellis or mesh, and in particular according to its width which is determined by the number of wires.
- secondary wires are welded transversely at their point of intersection, using spot welding devices.
- the resulting mesh comprises rectangular or square meshes, the dimensions of which depend on the spaces left between the longitudinal wires and the transverse secondary wires. Of course, such meshes always necessarily have corners at right angles.
- This construction technique has a number of disadvantages: the construction process requires the use of several wires and coils, which requires suitable equipment, and a substantial space available in front of the production machine.
- the objective of the invention is to propose a machine considerably simplified compared to its predecessors, and which makes it possible to obtain an infinite variety of patterns for the production of the mesh.
- This machine allows the manufacture of a continuous strip of wire mesh by means of a single flexible metal wire which feeds it continuously, said wire mesh being constituted by the repetition in a plane of the same pattern of metal wire, each pattern being superimposed on the previous one with a constant pitch shift in the axial direction of manufacture of the mesh strip.
- the flexible metal wire storage stage consists simply of a coil of free wire rotating in a support.
- the wire supply stage of the machine successively comprises: means for straightening the wire, intended to make it straight, at least one pulley for guiding the wire towards - a rotary device for winding around a drum.
- This drum is in reality an integral part of the subsequent stage, that is to say of the forming stage, which comprises a forming drum kept fixed during the forming, around which the metal wire is wound. It is the turns resulting from the winding which constitute the basic patterns of the fence. Although remaining fixed during the forming operation, this drum is pivotable relative to the forming axis, in order to increase the number of achievable patterns.
- a simple winding around the forming drum is often not sufficient for the wire to take the shape of the wall or external surface of the latter. This is why, additional means for forcing the wire to conform to the shape of said drum are provided on the periphery of the latter, means the movement of which is synchronized with the movement of winding of the wire. The purpose of synchronization is to ensure that the implementation of said means occurs at an appropriate time with respect to the production of each turn.
- said turns do not remain wound around the forming drum, but are supported by the transfer stage, which consists of a unwinding drum coaxial with the forming drum and provided with helical threads, animated by a rotational movement synchronized with the winding speed of the wire which allows the dissociation of the turns forming the patterns of the mesh.
- the transfer stage which consists of a unwinding drum coaxial with the forming drum and provided with helical threads, animated by a rotational movement synchronized with the winding speed of the wire which allows the dissociation of the turns forming the patterns of the mesh.
- Devices making it possible to deposit each turn on the plane of formation of the mesh are then placed on the periphery of the unwinding drum, at its end distant from the forming drum, the movement of these devices also being synchronized with that of said unwinding drum. .
- the turns forming the basic patterns of the grid are dissociated from each other, then deposited in the same plane in which the constitution of the grid proper takes place.
- the stage making it possible to maintain each pattern in the grid-forming plane and to shift it by a constant step before the arrival of the next pattern consists of a plurality of endless bands, arranged in parallel and driven at the same speed, which is synchronized with the speed at which the metal wire patterns are formed, the said bands comprising teeth at regular intervals allowing the driving of each pattern placed on the plane they form.
- the speed of said bands has a particular influence on the spacing of the different patterns, and consequently on the mesh, that is to say the shape and the surface of each mesh.
- the basic patterns forming the grid are therefore positioned relative to each other, before being then fixed in said position.
- the means for fixing the metal wire patterns together consist of at least one welding bridge disposed transversely to the axis of movement of the mesh, which may be preceded by a device allowing the contact in contact with the patterns located in the same cross section. It should be noted that the welding can be carried out, by at least one bridge, either in a vertical direction, or in a horizontal direction.
- the mesh strip is then completed.
- the general means constituting the wire mesh manufacturing machine having been envisaged, it is now appropriate to look at them in a more detailed manner.
- the winding device comprises in particular a hollow rotary shaft through which the wire passes after guiding by at least one pulley orienting said wire towards said shaft, the outlet of which is equipped with a pulley reorienting the wire in a direction of radial appearance towards an external winding pulley whose axis forms an acute angle with the axis of rotation of the winding device.
- the circular movement of this pulley has a radius greater than that of the winding drum.
- said winding device is driven by an electric motor.
- the speed of this electric motor, as well as the positioning of the external winding pulley, constitute in particular bases for the synchronization of the whole machine.
- the forming drum is arranged coaxially with the winding device, in line with the hollow shaft.
- radial spring pushers hold the wire wrapped around the drum. Their purpose is to prevent the turns from relaxing around the static forming drum, before entering the next step.
- a simple winding may be sufficient to achieve the final shape of the turns.
- a corresponding number of devices intended to press the wire against the said surface or surfaces is provided at the periphery of said drum, the movement of this or these devices then being synchronized with the speed transmitted by the winding motor.
- the device aimed at pressing the wire against a concave surface makes it take the form of a reentrant arc, consists of a rotary member with an axis of rotation parallel to the axis of the drum and provided with a wing. perpendicular to said axis, the outer edge of which is provided with means for guiding the metal wire and has a path, a section of which follows the shape of the concave surface.
- said wing has two sections, a first section with an elliptical outer edge provided with at least one wire guide roller, and a second section traced in continuity with the first, forming an arc of a circle and comprising a flange parallel to the axis of rotation provided with a guide groove, the rotation of the wire plating device being provided so that the elliptical section enters first into the concavity of the drum.
- the guide rollers of said elliptical section are a plurality distributed along its edge, a roller of larger diameter fitted to the end of said section penetrating first into the concavity.
- the device aimed at pressing the wire into said recess of the wall of the drum consists of a pusher whose removable head has a shape matching said recess, said head being movable in translation with a synchronized movement at the winding speed.
- the pusher is controlled by a motor actuating, via a gear, a rack equipping the shaft at the end of which the head is fixed.
- the pusher can also be actuated by a piston or by a linear motor.
- each turn has the precise shape of the forming drum, and it is ready to be moved to the plane of formation of the grid, of which it forms a basic pattern.
- the turns are then separated by a unwinding drum, and at least one fixed device for axially guiding the turns is placed along and in the extension of said unwinding drum.
- Said guidance is in fact provided by at least one internal guide arranged opposite an external guide.
- Each pair of guides defines a passage respecting the shape of each turn, and is arranged according to the threads of the unwinding drum, at least in a place where the pattern has an outward projection.
- each basic pattern of the mesh (a unwound turn) is individualized and ready to be used for the manufacture of the mesh.
- the devices enabling the unwound turns to be deposited on the grid formation plane then consist of worm shafts arranged at regular intervals at the periphery and in the axial extension of the unwinding drum, said shafts being driven by synchronized electric motors. so that their actuation is successive and allow the gentle extraction of one turn forming a grid pattern after another.
- the turns being unwound by helical threads they appear, at the outlet of the unwinding drum and of the guide devices, along a plane whose orientation is not strictly perpendicular to the axis of these devices. It is therefore preferable that the worms, which support each turn, be actuated successively individually or in groups, depending on the positioning of the portion of the turn for which they are responsible.
- Each turn or basic pattern of the grid is then placed on the formation plane, which then proceeds by successive shifting of each pattern, and consists of a central chain and two side chains provided with teeth for driving said patterns, which are moved by motors synchronized with each other and with the motors of worm devices.
- said chains are surmounted by a guide strip and fixed rigid protections, intended to preserve the relative positioning of the turns.
- sliding plates are arranged under the mesh, at the ends of the chains located at a distance from the pattern manufacturing system. At this stage of manufacture, the grid is formed, but the basic patterns which form it are not attached to each other.
- Said fixing is carried out by means of two transverse welding bridges operating in a vertical direction, each preceded by a bridge for holding the patterns forming the grid, each bridge being provided with two heads arranged on either side of the grid, each exerting an action in the direction of the other head.
- the heads of the retaining bridges are removable and have respectively male and female reliefs corresponding to the patterns forming the grid, and allow interpenetration aimed at pressing said patterns in contact with each other for welding. In terms of welding, the turns are therefore perfectly in contact with each other.
- the welding bridges perform spot welding at least at some of the intersections of the patterns in a transverse direction, preferably in two parts corresponding to two transverse configurations of the points of intersection of the patterns forming the grid.
- the additional volume can be configured so that it fits into at least one portion of concave surface of the wall of the drum to define a new portion of external wall, for example planar or convex. It is also possible that said additional volume is configured so that it fits into at least a portion of concave surface of the wall of the drum to define a new wall portion provided with a recess.
- the machine of the invention may comprise at least one additional spool of wire disposed next to the plane of formation of the mesh, the wire then being directed towards one face of the strip of mesh during running reoriented parallel to said scrolling, then fixed to the mesh strip.
- the coils are two or four in number, the wires then being directed respectively to one or both sides of the mesh strip.
- the machine of the invention can also include a continuous axial stamping stage of at least one transverse portion of the mesh strip. According to one possibility, the stamping can be carried out in two transverse portions running along the edges of the mesh strip.
- the machine can of course be automated, using a central electronic machine management unit, the parameters of which can be adjusted using peripherals accessible to the user, said central unit processing signals from sensors. signaling the instantaneous state of certain moving machine components.
- the peripherals accessible to the user consist of a screen and a keyboard. More preferably, said central unit and the peripherals are part of a microcomputer comprising a program for managing the machine.
- the elements of the machine on which the sensors have been placed are the control members of the various rotary elements, namely the electric motors. These sensors provide information on the position and speed of each of the motors, and the central unit, on which a machine management program runs, performs relative synchronization of all of these motors to result in the operation of the machine as as described.
- the invention does not only relate to the machine for manufacturing the continuous mesh strip, but also to the mesh strip produced using this machine, which is characterized in that it is formed by repeating a single pattern offset along its axis of constitution, said patterns being welded to each other at at least some of their intersections.
- the strip may be provided, on at least one of its faces, with at least one wire which is fixed thereto axially continuously.
- the invention relates to a process for the continuous production of a strip of mesh by means of a single metal wire, characterized by the following steps: - winding of the metal wire around a forming drum, each turn then having an identical pattern; - separation of the turns in the direction of the axis of the forming drum; - depositing the turns on a grid forming plane oriented perpendicular to said axis of the forming drum; - continuous movement of said plane, synchronized with the speeds of winding, separation and removal of the turns, to create a gap between the turns and form a succession of repetitive patterns of the mesh; and - welding at least some of the points of intersection of said patterns.
- the characteristics of the manufacturing process naturally reflect the potential of the aforementioned machine.
- the wire is unwound continuously from a single storage reel.
- the welding step is followed by a step of cutting the mesh strip to the desired length.
- the user of the machine can therefore, at his discretion, choose the length of mesh to be produced, either for the custom production of predetermined sections, or for the production of rolls to be industrialized.
- the process is different depending on whether or not the shape of the forming drum has hollow parts.
- the forming by winding around a drum is carried out, when the external wall of the drum comprises at least one concave portion and / or at least one recess, by a corresponding number of devices aimed at pressing the wire against said portion of wall. external.
- the manufacturing process according to the invention can be automated using a central electronic unit or a microcomputer equipped with peripherals allowing its adjustment by the user and responding to sensors marking the progress of the various stages put implemented during the process.

- each figure does not contain all of the numerical references of the elements which appear there, so as not to unnecessarily overload said figures.
- each figure aims to detail the explanation of a particular part of the machine, which then includes all of the references necessary for the explanation.
- the metal wire (20) supplying the machine for manufacturing a mesh strip is stored by winding on a coil (21), free to rotate in a support (22).
- the wire (20) passes first through a straightening device (23) which aims to eliminate the possibly twisted or folded portions, then through two pulleys (25, 26) which guide it to at the entrance to the machine itself.
- the upper portion thereof is covered by a cover (27), which is secured, as well as a number of other elements of the machine, to a structure referenced (24) forming the frame of the machine.
- the mesh strip (100) is produced using a succession of a single pattern forming the basic structure of said mesh (100), and which is repeated with a constant pitch shift.
- the mesh strip is therefore produced continuously by successive addition of the same pattern on a plane materialized by three endless chains (72), on which is placed each pattern forming the base of the mesh (100).
- the drive speed of said chains (72) obtained by drive motors (69) synchronized with the production speed of each pattern, allows the determination of the pitch separating two successive patterns.
- the deposition of each basic pattern of the grid is carried out using endless screws (60) distributed around the vertical structure forming the machine manufacturing each pattern according to a process which will be explained in more detail below. Downstream of this machine, and to fix the different patterns together in order to produce a rigid mesh (100), two welding bridges (89, 92) are arranged transversely to the mesh strip.
- a cutting device (97) follows the second welding bridge (92), and allows the cutting of the grid strip into sections of predetermined lengths.
- a table (99) provided with transverse rollers (98) allows the handling of the mesh sections at the end of production.
- the two welding bridges (89, 92), as well as the cutting device (97), comprise at their respective entry a device for holding the strip comprising two heads arranged on either side of the said strip of mesh.
- Coils (102) of metal wire arranged laterally make it possible to add, on at least one face of the mesh (100) being formed, wires (101) which are fixed to said mesh (100) in an axial direction.
- wires (101) which develop longitudinally for example in the vicinity of the lateral edges of the grid (100), can if necessary reinforce the structure of the latter. They can be arranged, in the event that they are fixed on the two faces of the mesh (100), opposite or offset.
- the change of direction of the wire (101) between its feeding phase, during which it is substantially perpendicular to the running axis of the mesh (100), and its welding phase to the latter, is carried out in a known manner per se, for example using pulleys (not shown).
- Figure 2 broadly shows the elements of Figure 1, with a slightly more precise vision of the central body of the machine, configuration substantially vertical and arranged in the axis of the cover (27).
- the profile structure (24) supports almost all of the elements of this machine.
- the endless chains (72) rotate around toothed sprockets (71) arranged at their longitudinal ends, one of which is directly driven by a motor (69).
- This figure shows the positioning, relative to the vertical configuration of the machine, of the devices (50) allowing the wire to be pressed into concave portions of the forming drum, as will be explained in more detail below.
- These devices which already appear in FIG. 1, are driven by motors (55) provided with a position and speed sensor (56), and they are in particular provided with a part (51) producing said plating.
- These plating devices also appear particularly clearly in FIG. 3, the motors (55) being separated from the active wing (50) by a reduction gear (54).
- the winding device the operation of which will be seen in particular in FIG.
- FIG. 7 is driven by a motor (299) also appearing in FIG. 2. Still with reference to FIG. 3, this view shows the unwinding drum (34), and its position relative to the endless screws (60) making it possible to deposit each turn on the endless chains (72).
- the reducers (68) equipping the drive motors (69) of said chains (72) are visible.
- These reducers (68) are also visible in FIG. 4, which also show that the drive motors (69) of the three endless chains (72) are equipped with position and speed sensors (70).
- This figure also illustrates the fact that the central chain (72) is longer than the lateral chains (72), which stop downstream of the first welding bridge (89), while the first cited stops downstream of the second welding bridge (92).
- This top view shows a configuration in which four wire plating devices are installed, making it possible to obtain a grid as shown, each pattern of which is provided with four concave arcs.
- the active part or wing (50) of these plating devices comprises two portions whose external fields constitute two arcs of different geometry, in continuity with each other, and whose one has guide rollers (52, 53) (see FIGS. 8A to 8C). It should be noted that in all the figures described so far, certain parts of the structure (24) are deleted to allow a better reading of the figure.
- FIGS. 6A and 6B show that the unwinding drum (34) is provided with threads (36) making it possible to individualize each turn (35).
- FIGS. 6C and 6D specify the positioning and the operation of each external guide (44), in cooperation with an internal guide (43), said guides having a shape depending in fact on the configuration of the turns obtained after winding on the forming drum .
- the external guides (44), housing the internal guides (43), therefore have a corresponding obviously.
- the internal guides (43) are in particular fixed to a plate (37) disposed under the unwinding drum (34) (see FIG. 7).
- the internal (43) and external (44) guides are not arranged at the same level, to reflect the inclination of the threads (36).
- the motor of the winding device (device appearing in detail in FIG. 7) is connected to the latter via a reduction gear (298), and it is provided with a speed and position sensor. (300).
- This winding device comprises in particular an external pulley (31) allowing the winding of the wire around the forming drum (33), said pulley (31) being integral with a rotary plate (30), as shown more in detail in the section of FIG. 7.
- the angular position of the forming and unwinding assembly can be modified (see FIG. 6D) so as to further increase the possibilities of patterns applicable to the fences of the invention.
- FIG. 6D The angular position of the forming and unwinding assembly can be modified (see FIG. 6D) so as to further increase the possibilities of patterns applicable to the fences of the invention.
- a pulley (29) with the same axis of rotation as the pulley (26) allows the wire to be redirected in a radial direction relative to the axis of rotation of the shaft (28 ).
- Said wire (20) is then directed towards an inclined pulley (31), disposed at the periphery of a rotary plate (30), and which allows the winding of the wire around a fixed drum (33).
- This drum (33) is the forming drum giving each turn the shape of the basic pattern of the mesh.
- This drum is supported by a plate (32) provided with a mechanical connection with the hollow shaft (28), which however does not communicate the rotary movement of the latter to said plate (32) due to the existence of the bearing. ball (284).
- Said drum (33) is therefore static although the shaft to which it is fixed is rotary, due to the existence of two intermediate gears.
- One of these intermediate gears (278) is connected to the frame of the winding machine (27), while the other intermediate gear (283) is connected to the rotary plate (32). They are connected by two satellite gears (279, 281). These satellites are secured to a sleeve (282) rotating around a shaft (280), which is supported by the rotating plate (30) connected to the rotating hollow shaft (28), which allows the immobility of the drum ( 33).
- the lower plate (37) to which are fixed in particular the internal guides (43) having the exact shape of the projecting portions of each turn formed by the drum (33), is stationary although it is not fixed to the frame . It is also mechanically connected to one end of the hollow shaft (28), without moving or rotating with it. The reason is that the same structure with two intermediate gears is used, one of the gears (286) being fixed to the forming drum (33), while the other (291) is secured to said lower end plate (37). These two intermediate gears are connected by satellites (287, 290) arranged on either side of a sleeve (289) and rotating around an axis (288).
- This sleeve (289) is supported by the unwinding drum (34), which is itself connected to the hollow shaft (28), which has the effect of leaving the plate (37) stationary freely connected to the shaft hollow (28).
- the intermediate gear (291) is connected to the central shaft via two ball bearings (292, 294), the latter being protected by a cover (295).
- the plate (37) proper is connected via a support (293) to the intermediate gear (291).
- the unwinding drum (34) has a central stiffening plate (296). In this FIG. 7, the helical threads (36) also appear, justifying the difference in the levels of processing of the wire between the internal (43) and external (44) guides located on either side of the central axis of the shaft. (28).
- FIGS. 8A to 8C describe precisely the devices for plating the wire against concave portions of the wall of the forming drum (33).
- the edge (52) first of all is a portion of an ellipse, while the edge (51) is an arc of a circle.
- the first city makes it possible to initiate the curvature of the wire, by means of guide rollers (52, 53), to allow it to match the concave surface of the drum (33).
- the edge portion in an arc (51) has a thicker side edge, provided with a groove also allowing the guide of the wire (20).
- the device is rotated counterclockwise, that is to say that the wire is first guided by the larger diameter roller (53), then by the rollers of lower diameter (52) which begin to push it inside the cavity of the external wall of the drum (33), the field (51) finishing the plating by perfectly matching the shape of the concavity.
- Figures 9A to 9C show the precise operation of the worms for depositing each turn on the chain (72) provided with the teeth (73).
- Each of the worm shafts (60), provided with helical lips (61) is driven by a motor (64) at the outlet of which there is a reduction gear (63).
- Each motor also has a speed and position sensor (65).
- the helical thread (61) begins at the top, at the bottom end of the unwinding drum (33) (see Figure 3) and ends at the bottom of a chain cavity (72) separating two teeth (73).
- the two motors for example rotate at the same time, but in the opposite direction reverse. They therefore allow the turn to descend gradually to be inserted between two adjacent teeth (73) of the central chain (72).
- a protective device (45) overcomes the teeth, a passage being nevertheless opened with guides flared (47) to allow the insertion of the coil (35), between two teeth (73) and between the two worm devices (60).
- an upper protective strip (46) with an L-shaped section allows the holding of each turn inside the teeth, said strip (46) also comprising an opening between the two motors for the insertion of each turn (35), with flared guides (47).
- FIG. 11A and 11B show the configuration of the first spot welding station (89) comprising an upper (90) and lower (91) welding head, the assembly being preceded by upper (82) and lower holding jaws (83) integral with a respectively upper (81) and lower (84) retaining head.
- the movement of these holding and welding heads is simultaneous, the respectively upper (90, 81) and lower (91, 84) heads being joined together.
- the upper holding jaw (82) has recessed reliefs in which male reliefs fitted to the lower jaw (83) fit, said reliefs having the at least partial shape of the meshes according to the intersection points to be welded. This is what appears in gray in FIG. 11 B.
- FIGS. 14A to 14D show the configuration of a pusher allowing the wire to be pressed into recesses of the forming drum (33).
- These pushers include a head (58), the end of which is configured as a function of said recesses, said head (58) being consequently removable.
- these heads (58) are fixed via a tool holder (59) to a shaft (57) provided with a rack, said rack being driven in rectilinear movement by a gear of a reducer (66) disposed at the output of the drive motor (67).
- FIGS. 15A to 15D show a configuration of a drum (33A) in a four-pointed star, with four concave surfaces. It is possible to fill these surfaces with additional volumes (41 A to 41 C) to produce basic patterns of different toasting from the same basic drum (33A). The same goes for the structure illustrated in FIGS.
- FIGS. 16A to 16D illustrate another possible configuration of the base drum (33C) with additional volumes (41 D to 41 F) particularly suited to this new configuration.
- the base drum (33D) illustrated in FIG. 16E at 16H, having five concave portions distributed in two groups of different arcs, can be combined with the additional volumes (41 A to 41 C) shown in FIG. 15.
- a block diagram makes it possible to understand the automated management of the machine, either using a microcomputer (76) controlled by the user which has a control interface (77) a processing program, which sends and receives signals using a communication network (74) which controls: the winding motor (299) and receives signals via the sensor (300) the motors driving (55) devices for placing the wire in concave portions, and receiving information from the sensors (56) associated with these motors; the motors (64) controlling the worms depositing the turns on the chains (72), and receiving information from the sensors (65) associated therewith; and - the drive motors (69) of the chains (72), and receives signals from the sensors (70) associated therewith.
- a communication network (74) which controls: the winding motor (299) and receives signals via the sensor (300) the motors driving (55) devices for placing the wire in concave portions, and receiving information from the sensors (56) associated with these motors; the motors (64) controlling the worms depositing the turns on the chains (72), and receiving information from the
- An electronic control card for movement and synchronization of the system (75) allows the management of the assembly and in particular comprises a converter stage (78) of the signals and a control system (79) of the signals emanating from the various sensors placed on engines.
- a converter stage (78) of the signals and a control system (79) of the signals emanating from the various sensors placed on engines.
- FIGS. 19-A1 to 19-N1 numerous configurations of basic drums have been illustrated, to which additional volumes have been added if necessary. In all cases, if the configuration provided with additional volumes requires the use of wire plating devices, either in concave portions or in recesses, these devices have been shown with their operating offset resulting from the speed of wire winding. In parallel, for each figure, the grid (100) obtained is shown.
- the base drum (33A) is combined with two additional volumes (41 B) forming out of two from the sides a convex surface which does not require any additional plating device.
- the two remaining concave surfaces require the activation of plating devices (50). These devices (50) are put into action one after the other, with a phase shift dependent on the speed of rotation of the drive motor of the winding device, and controlled by the aforementioned electronics.
- FIG. 19-A2 in which no additional volume (41 B) is provided, and which then requires four plating devices operating in phase quadrature.
- the two additional volumes (41 C) include a central recess which requires the use of a pusher (57).
- the synchronization of the two devices (50) for plating the wire in a concave surface and of the two pushers (57) is done in the same way, in phase quadrature, taking into account the technical characteristics of the motors (55, 67) actuating d on the one hand the rotary devices, and on the other hand the devices in which the rotation is transformed into a rectilinear displacement.
- This last question does not arise for the representation of figure 19-B3 in which the four pushers (57) are actuated in phase quadrature.
- FIG. 19-C2 In certain cases, as in the figure 19-C2, one can be brought to bring into play four devices (50) applicable to concave surfaces and pushing devices (57) whose heads (58) are adapted to the additional volume (41 G).
- Figures 19-C5 and 19-C6 show alternatives for manufacturing the mesh (100) appearing in Figure 19-C1, respectively with two and four pushers whose heads fulfill the same function as the plating devices.
- Figure 19-C7 shows a manufacturing variant requiring neither pushers nor plating devices. It should be noted that when we are dealing with a concave surface, we can also use a pusher device (57), but with a head (58) as illustrated for example in FIG. 19-D4, which hugs said surface concave, and performs the plating by radial thrust.
- FIGS. 19-N1 to 19-N3 represent in particular three additional possibilities of manufacturing and / or processing the gratings (100): - in 19-N1, the forming drum (33) is pivoted by an angle of X ° ; - In 19-N2, as appears in section, to the right of the representation of the grid (100), the latter has been stamped longitudinally in the vicinity of its borders; and - in 19-N3, additional axial metal wires were added (see section) along the edges, on either side of the mesh.
