Definitions

  • the present invention relates to a movable-bottom spinning can for yarns and/or fibres.
  • the above mentioned can or vats are filled-in by fibres, and are provided with side fixed walls and a movable bottom which is lowered and raised depending on the weight exerted thereon.
  • This bottom tends to downwardly move under the weight of the textile fibres, introduced into said cans and/or vats.
  • the cans are progressively emptied, and since, as it should be apparent, the weight of the fibres tends to decrease, the movable bottom, biassed by urging springs, tends to raise so as to always hold at an upward position the roving and/or textile fibres to be processed.
  • the upward location of the roving and/or fibres is such as to hold the roving always at an optimum position to be taken up from the can.
  • the aim of the present invention is to overcome the above mentioned problems, by providing a movable-bottom spinning can for yarns and/or fibres, the movable bottom of which can be always displaced with a parallel relationship to itself, thereby overcoming the problem of undesired unbalanced loads.
  • a main object of the present invention is to provide such a parallelepipedal shape spinning can, in which the movable bottom is always prevented from being undesirably slanted, even if the yarn or fibre load is taken up in an unbalanced manner.
  • Another object of the present invention is to provide such a movable bottom yarn and/or fibre spinning can which, owing to its specific construction features, is very reliable and safe in operation.
  • Yet another object of the present invention is to provide such a spinning can which can be easily made starting from easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
  • a movable-bottom spinning can for yarns and/or fibres comprising a holding body, including a movable bottom urged by resilient means, characterized in that said resilient means comprise a central spring arranged between pantograph elements operating between said movable bottom and a fixed bottom of said holding body.
  • the movable-bottom spinning frame for yarns and/or fibres which has been generally indicated by the reference number 1, comprises a holding body 2, of substantially parallelepipedal shape and including a preferably rectangular base, which is provided with a fixed bottom 3.
  • a movable bottom 4 which is coupled to resilient means, generally indicated by the reference number 5.
  • the main feature of the invention is that the aforesaid resilient means are constituted by a central spring 10, of a coil or helical type, which is connected between the movable bottom 4 and a lower bottom 11, superimposed on the fixed bottom 3 of the body 2.
  • said pantograph elements 15 comprise rods 16, mutually articulated pantograph-like, with the end rod being articulated or pivoted at 17, respectively to the movable bottom 4 and the lower bottom 11, whereas, on the other portions thereof, the rods 16 are provided with a sliding roller 18, which can be displaced in a guide seat 19.
  • pantograph elements 15 are coupled to one another by cross-elements 20 which, at their intermediate positions, are rigidly coupled to the turns of the coil spring 10, so as to allow the spring to elongate in an even manner.
  • the movable bottom 4 will be lowered, so as to approach the lower bottom, and the rods 16 of the pantograph will be mutually closed with a consequent sliding movement of the rollers 18 in the guide seats 19.
  • the resilient operation of the spring will cause the pantograph elements 15 to be extended, so as to cause the movable bottom 4 to be displaced parallel to itself, without any jams or unbalanced effects, even in a case in which the load thereon is taken up in an uneven manner.
  • the spring 10 is associated with bent wings 30 which are provided at the movable bottom and lower bottom.
  • pantograph elements which practically define the spring housing region and which interconnect the movable bottom to the fixed bottom, will allow the movable bottom to be always displaced parallel to itself, under all of the use conditions.
  • the used materials provided that they are compatible to the intended use, as well as the contingent size and shapes, can be any, depending on requirements.
