Definitions

  • the present invention relates to a grinding machine, specifically designed for a grinding tubular fabrics.
  • the fabric is subjected to a finishing process which is carried out by a grinding machine, comprising a plurality of abrasive coated cylinders, the grain size of the abrasive material depending on the result to be obtained; in such a grinding machine, the fabric is caused to pass under tension under said abrasive coated cylinders.
  • a grinding machine comprising a plurality of abrasive coated cylinders, the grain size of the abrasive material depending on the result to be obtained; in such a grinding machine, the fabric is caused to pass under tension under said abrasive coated cylinders.
  • the tubular fabric piece may be affected, after a grinding process, by defects, for example a continuous line, which, while having a reduced size, constitutes anyhow a processing defect.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a grinding machine, specifically designed for grinding tubular fabrics, allowing to carry out the grinding operation without causing processing defects at the fabric edge portions, and without the need of carrying out finishing grinding operations.
  • a main object of the present invention is to provide such a tubular fabric grinding machine which is adapted to operate substantially according to the operating method of prior grinding machines, with additional advantage of providing a fully finished product.
  • Another object of the present invention is to provide such a tubular fabric grinding machine which, owing to its specifically designed construction, is very reliable and safe in operation.
  • Yet another object of the present invention is to provide such a tubular fabric grinding machine which can be easily made by starting from easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
  • a grinding machine specifically designed for grinding tubular fabrics, characterized in that said grinding machine comprises, on a supporting framework, a first grinding assembly, operating on a tubular fabric arranged on a first plane and a second grinding assembly, operating on said tubular fabric arranged on a second plane angularly offset from said first plane.
  • Figure 1 is a perspective schematic view illustrating the grinding machine according to the invention
  • Figure 2 is a further perspective view illustrating the first and second grinding assemblies included in the tubular fabric grinding machine according to the invention.
  • Figure 3 is a side elevation view illustrating the grinding machine according to the invention;
  • Figure 4 is a front elevation view illustrating the grinding machine according to the invention.
  • Figure 5 is a top plan view illustrating the grinding assemblies included in the grinding machine according to the invention.
  • Figure 6 is a schematic view illustrating the arrangement of spreading disc elements inside the tubular fabric.
  • Figure 7 is a cross-sectional view illustrating, on an enlarged scale, a pair of spreading or widening disc elements .
  • the grinding machine specifically designed for grinding tubular fabrics, according to the present invention, which has been generally indicated by the reference number 1, comprises a supporting framework 2 , to which a tubular fabric 3 is fed from a fabric feeding station 4, of a conventional type.
  • the tubular fabric in a flattened condition, is fed to a first grinding assembly, generally indicated by the reference number 10, which comprises a plurality of grinding rollers 11, operating on the tubular fabric 3 being fed.
  • a first retractor or spreader device for holding the tubular fabric in a plane corresponding to that on which the grinding operation has been carried out.
  • a second fabric retractor or spreader assembly is provided, generally indicated by the reference number 16, which is construction-wise like to the assembly 15 and operates to spread the fabric on a second plane, likewise offset from the first plane on which the tubular fabric at the first spreader assemblies lays.
  • a second grinding assembly Downstream of the second spreader assembly, a second grinding assembly, generally indicated by the reference number 20 is arranged; said second grinding assembly performs a further grinding operation on the fabric and, most importantly, it performs the grinding operation on the lines, indicated by 30, which are formed at the tubular fabric 3 edge portion during the first grinding operation.
  • the spreader assemblies 15 and 16 comprise spreading disc elements 21 and 22 which are opposite to one another and are rotatably supported by respective supporting pin elements 23 and 24.
  • Said pin elements engage on the outside of the fabric 3, at the edge portions thereof.
  • a toroidal ring element 25 is arranged inside said tubular fabric 3, said ring element engaging between the rollers thereby preventing the tubular fabric from disengaging from the disc element.
  • Said ring element 25 has a cross-section larger than the spacing of the spreader discs 21 and 22.
  • the grinding machine according to the present invention allows to perform, by very simple operating means, an optimum finishing continuous process through the overall extension of the tubular fabric.
