Definitions

  • the present invention relates to a tensioner for condensing bags of the type used in spinning machines to achieve a greater parallel order of the fibres and thus reduce the hairiness of the yarn.
  • the condensing bags known at present are tensioned by bars provided with recesses that act on a plurality of successive bags, acting by gravity or by means of springs, giving slight tension to said bags.
  • These tensioning rods generally act on six or eight perforated bags so that the spinning machines, which may have up to 1400 or more perforated bags, are divided into spans or sections of six or eight positions (spindles).
  • the perforated bags do not all have exactly the same internal diameter. This tolerance effect is also affected by the work to which the bags and the components on which they rest are subjected, with an additional increase in the individual dimensions because of factors such as temperature, humidity, friction, etc.
  • the tensioning rod may adopt an anomalous position even compromising the guide for the perforated bags produced by the recessed areas of said rod.
  • the tensioner according to the present invention is designed to connect directly the tubular guide component of the parallelising bag and the bag itself, also taking into account that simple and practical assembly should be achieved. Accordingly, the tensioner according to the present invention has an area for connection by a mere gripping action on the bag support and an area of direct tensioning at one end thereof. It therefore has a basically two-part structure and an intermediate spring.
  • the parts may be manufactured by injection moulding of synthetic materials and are characterised in that one of them is designed to be connected by easy methods to the bag support and the other is inserted in the first, receiving the action of a spring and acting at the other end on the bag by its having lateral guide tabs.
  • the perforated fibre condensing bag indicated by reference numeral -1- rests on a rotating driving roller -2- which drags the bag by the tangency produced by the freely rotating roller covered with rubber -4- which acts on the belt as it passes over the driving roller - 2-.
  • the belt -1- therefore has the same speed as the driving roller -2-.
  • a tubular component or static section -3- also receives the perforated bag, particularly on its upper grooved portion -3'-, the inside of said tubular component being connected to a vacuum source.
  • the tensioner according to the present invention is designed to tension the bag -1- individually, in other words, each of the condensing bags is allocated an individual tensioner. This is very important since the constant rotation of the perforated bag without sliding over the driving roller -2- with neither loss nor variation of speed is very important to achieve high yarn production speeds and high yarn quality. Thus, the tensioner according to the present invention improves the quality of the yarns very substantially compared with the state of the art.
  • the tensioner according to the present invention in the embodiment shown in the example, has a body -6- fixed to a portion of the tubular component -3- and a tensioner skid -7- that acts on the bag -1-.
  • An opposing means for example, a spiral spring -11- between said parts -6- and -7- or another similar means produces suitable tensioning of the bag.
  • the tensioner has a very simple structure using a body -6- moulded from a synthetic material that has end wings -8- and -9- designed to connect by nipping at one end of the tubular component -3-.
  • the skid -7- slides along a central shaft -10- of the body -6- and receives the opposing action of the internal spiral spring -11- or other similar means.
  • said skid In the upper contact portion of the skid with the bag -1- said skid has lateral centering and retaining flanges -12- and -12'- which laterally centre the bag.
  • the upper portion of the skid -7- has small apertures -13- and -14-.
