Definitions

  • the present invention relates to an apparatus for replacing fabric pieces in textile spreading machines.
  • cloth fabrics for preparing cloth articles are usually spread,before a cutting step, in superimposed layers so as to form the so called "matress".
  • the exhausted fabric piece After having formed the matress,the exhausted fabric piece must be replaced by another piece,for preparing a new matress.
  • the fabric piece replacing operation is usually carried out by piece replacing apparatus which,however,operate in a semi-automatic way,and are controlled by an operator,which results in a compa­ratively long replacing time negatively affecting the cost of the finished product.
  • the main object of the present invention is to overcome the above mentioned drawbacks, by providing an apparatus for replacing fabric pieces, adapted to be associated with a textile spreading machine,and which operates in a fully automatic way.
  • Another object of the present invention is to provide such a fabric piece replacing apparatus which operates in a very quick and reliable way.
  • Yet another object of the present invention is to provide such a fabric piece replacing apparatus which is very simple construction-wise.
  • an apparatus for replacing fabric pieces in textile spreading machines characterized in that said apparatus comprises two pairs of driven carriages,mounted on vertical shoulders to be reciprocated in timed way along converging paths,said carriages bearing each a slide along the perimeter of which a chain is slidably driven,said chain being provided with restraining means for restraining a fabric piece mandrel to be unloaded or loaded from/on a piece supporting member of a spreading machine,said piece supporting member including restraining rollers for restraining by pairs said piece mandrel,said restraining rollers being mounted on supporting plates pivoted each at a respective end thereof and having another end thereof supported by articulated arms.
  • the apparatus for automatically replacing fabric pieces,adapted to be associated with fabric piece spreading machines comprises two driven carriage pairs (which have not been specifically shown),mounted on vertical shoulders 1 and reciprocated in a timed way along converg­ing paths.
  • Each of said carriage pair supports corresponding slides,respectively top slides 2 and bottom slides 2′, along the perimeter of which is slidably driven a chain provided with means for restraining the mandrel of a fabric piece to be unloaded from or loaded on a support­ing member 3 of the spreading machine.
  • the piece mandrel is restrain­ed on said supporting member by means of adjoining roller pairs 4 and 4′ which are rotatively mounted on corresponding supporting plates 5.
