Definitions

  • the present invention refers to a machine for fabrics inspection.
  • a process for the inspection of fabrics in pieces which consists, essentially, in the continuous unidirectional drive of a plurality of cascaded pieces for disposing them in correspondence of a backlighted plane for the visual inspection thereof by an operator, and in the subsequent collection of same pieces, for example with plaiting and/or rolling thereof, at a separate unloading station.
  • the pieces of fabric to be inspected are united between them in continuous succession in correspondence of respective leading and trailing edges, so that the trailing edge of each piece will result associated to the leading edge or "head" of the next piece, according to the fabric's direction of advancement .
  • a pieces-marking is operated which consists in applying an adhesive plate to the pieces which bears an indelible code of individualization and recognition of the main characteristics of them such as the weight, serial or article number, fabric nature, color and pattern.
  • the pieces thus united Prior to unloading, that is, after the inspection, the pieces thus united are separated from each other.
  • a technique is known consisting in the insertion of a pin through the head and tail of two pieces of fabric, after they have been manually superimposed, so as to allow for their temporary union.
  • the pin which is of a length substantially corresponding to the width of the pieces, is removed and fed to a respective collection site.
  • a further known technique for operating the said union of pieces to be delivered for inspection consists in the sewing of the tail of the first piece to the head of the next piece by means of a sewer being moved by the operator who provides for overlapping by hand the edges to be sewn in correspondence of the sewer head: said sewer being positioned on the same side of the operator with respect to the inspection plane.
  • the presence of the sewer reduces the freedom of movement of the operator who has to perform such movements which, in some case, may prevent the correct superimposition of the two pieces edges to be sewn and thus also the correct sewing thereof.
  • the main object of the present invention is to overcome the above drawbacks. This result has been achieved, according to the invention, by adopting the idea of providing a machine having the features described in the characterizing part of claims 1. Further characteristics being set forth in the dependent claims.
