Definitions

  • the present invention relates to a mat, in particular for synthetic turf, and to a method and an apparatus for manufacturing said mat .
  • the invention also relates to a synthetic turf structure including the mat .
  • synthetic turfs in particular for sports fields, consist of a mat formed by a primary substrate from which there extend vertically filaments that simulate a natural greensward .
  • infill material of various nature, for example sand and/or polymeric granules , "clog" the mat .
  • the filaments can be produced with yarns having various chemical compositions (for example, polypropylene, polyethylene, nylon, other polymeric fibres , etc . ) . It is likewise known that the yarns may be of different types or assume different structures ; for example, they could be fibrillated, single-stranded, curly, etc .
  • Fibrillation is basically a method whereby the yarn is cut in a discontinuous way lengthwise and assumes a conformation similar to a mesh .
  • the peculiar characteristic of fibrillated yarn is that of withholding within the "mesh” the components of the infill, whether they are granules of sand or rubber . Said mesh prevents displacement of the infill within the mat above all in the event of heavy rainfall .
  • the process is far from viable from the economic standpoint, in so far as curling reduces the height of a filament which had, however, been made and cut to a larger height (the same as that of the other yarn) , so that the entire portion of strand that is curled is in actual fact wasted.
  • the presence of the curl in part solves the problem of withholding the infill, it is compacted by being subj ected to treading, so that the mat becomes hard and loses its original elasticity .
  • One aim of the present invention is to provide a mat and a structure of synthetic turf comprising said mat which will enable the above highlighted drawbacks of the known art to be overcome .
  • a further aim of the invention is to provide a method and an apparatus for fabrication of the mat .
  • the present invention hence regards a mat, in particular for . synthetic turfs, as defined in the annexed Claim 1.
  • the mat according to the invention solves the problems highlighted previously of known techniques , in so far as it envisages combining two yarns and cutting them to two different heights . It is possible to use two yarns of different composition and/or different structural characteristics, and choose appropriately the two yarns , exploiting fully the peculiar characteristics thereof .
  • first fibrillated yarn that is cut to a first height and a second yarn (namely, a single-strand yarn) that is cut to a greater height .
  • the yarn that is cut shorter gives rise to filiform formations , which, thanks to the "mesh" typical of the fibrillated yarn, withhold the infill and moreover facilitate the laying operations , enabling the right amount of filling to be achieved, without, however, being visible (and hence j eopardizing the overall appearance of the grass covering) or being directly subj ected to wear .
  • the cut operation enables the part that in actual fact is not necessary not to be used, with considerable saving in terms of production costs .
  • the filiform formations of the second yarn are cut to a height greater than those of the first yarn so as to form the surface part of the mat .
  • Said filiform formations which come into direct contact with the players or athletes, bestow upon the mat longer duration, lower abrasion, and a better appearance, whereas the shorter filiform formations , in addition to withholding the infill , support the longer filiform formations, without being visible and without being subj ected to direct treading and hence to wear .
  • the technique according to the invention hence enables maximum exploitation of the various types and compositions of the yarns, exalting their peculiar characteristics and enabling at the same time a considerable economic saving .
  • the invention moreover regards a method and an apparatus for manufacturing the mat that has been described in summary previously, which are defined in Claims 6 and 10 respectively. Said method and apparatus enable a simple and economically advantageous fabrication of the mat according to the invention .
