Abstract
Description
- This invention concerns a divisible electrically welded mesh. To be more exact, the invention concerns an electrically welded mesh of the type employed in building work, for instance, which is obtained during manufacture with two counterpart meshes and is then divided in two.
- Such a mesh is produced with a plurality of lengthwise elements to which transverse elements are welded.
- At present the division of electrically welded mesh as manufactured takes place by continuous shearing of the transverse elements in correspondence with two lengthwise elements positioned very near each other. This shearing enables two workmen positioned downstream of the dividing shears to take the two meshes and overturn one of them on top of the other so as to take up less space during transport and storage.
- The lengthwise elements placed in an intermediate position during manufacture of the two-net mesh are located at present at a distance of three to five centimetres from each other.
- The stub ends of the transverse elements remaining after the shearing are normally of the same length as the stub ends protruding at the outer lengthwise edges of the two-net mesh.
- In this way the single meshes obtained are substantially equal on their long side both in themselves and to each other.
- This distance of three to five centimetres and the single shearing performed on the transverse elements do not enable the resulting two meshes to be divided laterally from each other.
- If a dividing element were inserted, the geometric structure of the mesh would be irreparably impaired and in certain cases would also affect the stability of the joints between the lengthwise and transverse elements.
- As a result of this objective difficulty the various systems designed heretofore for the embodiment of an overturning device able to replace the two workmen employed for the overturning have in fact failed.
- The need to produce an automatic overturning device has been greatly felt for a long time now for important reasons.
- On the one hand there is the need to increase the rate of hourly output, which is at present conditioned by the working capacity of the two workmen.
- On the other hand there is the need to embody the overturning device in such a way that it will not deform the electrically welded meshes.
- There is also the requirement to obtain lower operating costs and a much lower consumption of power.
- For this plurality of reasons and in order to obtain systems for engaging and overturning one mesh on the other as produced with the two-net electrically welded mesh, the present applicant has designed, tested and embodied this invention.
- According to the invention the central lengthwise elements are positioned at a distance between eight and fourteen centimetres, and advantageously ten centimetres, from each other.
- Since the outer protrusions of the transverse elements of the two nets of the mesh normally have a length of one point five or two point five centimetres, two problems would arise if the shearing took place at the median position between the central lengthwise elements.
- On the one hand the new mesh would not solve the problem of the application of the automatic overturning device, and on the other hand the mesh would not be symmetrical.
- Since the application of the overturning device requires either that the two resulting meshes, which, as we said earlier, have to be exact counterparts of each other, should be divided or that a free intermediate space should be created, the invention arranges that the portions of the transverse elements placed between the central lengthwise elements should be sheared at two points and that a scrap segment and free intermediate space should be created.
- Therefore, if the transverse elements protrude on the outer side of the mesh by about two centimetres and the central lengthwise elements are positioned about ten centimetres apart, the twofold shearing of the portions of the transverse elements positioned between the central lengthwise elements is carried out in a symmetrical position in relation to the lengthwise centre line of the mesh, thus creating a scrap segment of about six centimetres.
- This will provide the required division or rather the required free intermediate space without the mesh having to undergo stresses which might alter the geometric and structural conformation of the mesh.
- The invention is therefore embodied with a divisible two-net electrically welded mesh to provide two symmetrical electrically welded meshes with transverse elements protruding by a determined value, which mesh is characterized in that the two intermediate lengthwise elements are positioned on each side of the lengthwise centre line at a distance substantially of A+Aʹ+B from each other.
- The invention is also brought about with a method to obtain two symmetrical electrically welded meshes with transverse elements normally protruding by a determined value from a two-net electrically welded mesh, the method being characterized in that a required extent of lengthwise spacing is provided between the two meshes during manufacture, the two intermediate lengthwise elements positioned at the sides of the lengthwise centre line being located substantially at a distance of A+Aʹ+B from each other, the portions of the transverse elements positioned between the intermediate lengthwise elements being sheared at two points at a distance B from each other.
- The attached figures, which are given as a non-restrictive example, show the following:-
- Fig.1 shows a possible two-net electrically welded mesh employing the invention;
- Fig.2 gives a side view of the mesh of Fig.1;
- Fig.3 shows the invention.
- A two-net electrically
welded mesh 10 is obtained which compriseslengthwise elements 11 andtransverse elements 12. The lengthwise and transverse elements 11-12 may be arranged at a constant distance from each other as in Fig.1 or at a varied distance. - The
transverse elements 12 normally are at a constant distance, whereas thelengthwise elements 11 are either at a constant distance or at a varied distance, the twomeshes 14a and 14b complying with symmetry in relation to the lengthwise centre line of the two-net mesh 10. -
Lengthwise elements 111 positioned on each side of the centre line at adistance 13 from each other are comprised on each side of the lengthwise centre line of the two-net mesh 10. - On the outer long side of the
mesh 10 thetransverse elements 12 protrude by a length A and Aʹ; this length may vary between one or one point five centimetres and about two point five centimetres. The values of A and Aʹ may be the same or different. - According to the invention the distance therefore has a value of 2A+B, or rather of A+Aʹ+B, namely a value twice (2A) the value of the protrusion of the
transverse elements 12 from the long outer side of the mesh plus the value B. - The values A and Aʹ have been differentiated to show that they may be equal or different. If they are different, B will not be symmetrical in relation to the lengthwise centre line of the mesh.
- The value B, which is positioned substantially astride the lengthwise centre line, is the distance which determines the two
shearing points 15. - The value B is the value of the portions of the transverse elements which are sheared and discharged, so that the protruding stub ends having a length A remain on the
meshes 14a and 14b. - The free space thus created between the
meshes 14a and 14b enables a manipulator to be employed to overturn one of the meshes 14a and superimpose it on theother mesh 14b. - The spirit of the invention comprises in a variant a free space misaligned in relation to the lengthwise
central elements 111, thereby embodying protruding stub ends of different lengths.
