Definitions

  • a first subject of the invention is a process for forming, collecting and using slivers of carded material which are collected in containers by means of collectors whose movement usually consists of two circumferential movements to form layers of progressively offset coils, characterised in that at least two slivers, formed from respective sections of the front of the web coming off the carder and condensed and drawn by their own drawing units, are conveyed to the same collector, collected in the container beneath it and kept adjacent to each other; and in that the said slivers are drawn from the collecting container at the same time with the layers of coils being unwound, and are conveyed to the units for the next stage of processing either separately or together.
  • a second subject of the invention is equipment for forming, collecting and using slivers of carded material which are collected in containers by means of collectors whose movement usually consists of two circumferential movements to form layers of progressively offset coils, characterised in that it comprises the following combination of units : at the output end of the carding machine, devices for dividing the front of the web into at least two sections with their own condensing and drawing units; a single container for collecting sliver with its own collector; and devices for conveying the adjacent slivers and winding them into layers of adjacent coils which can be drawn off at the same time in order to send the said slivers to the next stages of use either separately or together.
  • the said hinged arm comprises adjacent grooved wheels or equivalent guide devices for two (or more) adjacent slivers.
  • Separate devices with guide openings for each sliver or one device with one guide opening for both slivers may be fitted upstream of the sliver return rollers.
  • a further subject of the invention is a collecting con­tainer for carded silver wound into layers of coils in which at least two slivers, forming the said layers of coils, are kept adjacent to each other in order to be drawn off at the same time and sent to the subsequent processing units either separately or together.
  • a doffer 3 which works in conjunction with a web detachment cylinder 4 which is able to convey the web being formed to a set of grooved wheels 5, 7.
  • the middle of doffer 3 is milled and this milling 9 creates a discontinuity in the clothing of the cylinder itself.
  • the said discontinuity in the clothing causes the web being formed to divide and be separated into two portions V1 and V2; the V1 portion is then conveyed to grooved wheels 5 whilst the V2 portion is conveyed to grooved wheels 7.
  • the said grooved wheel assemblies collect the two portions of web into two slivers N1 and N2 respectively and send them to two condensing and drawing assemblies 11, 13. When they leave the said condensing and drawing assemblies 11, 13 slivers N1 and N2 are passing over a pair of pulleys 15, 17 on a collector 19.
  • the said pulleys may have two races as shown in Fig. 2.
  • Top covers 12 of the said collector has guide devices for slivers N1 and N2.
  • the said guide devices may be of the type illustrated in Figs. 3 and 4, i.e. with a single opening 23 in which both slivers N1 and N2 meet.
  • the said guide devices may, however, also be of the type illustrated in Figs. 5 and 6, with two separate openings 25 and 27 for the two slivers N1 and N2.
  • the process and equipment illustrated enable a double sliver from a double-output and hence high-productivity carder to be collected in a single container. This enables the overall dimensions of the equipment as a whole to be reduced whilst retaining the option of feeding the two slivers collected in the joint container to two separate units on the machine which carries out the next operation.
  • the two slivers N1 and N2 are drawn from container 29 at the same time and so they can be conveyed to the next stages of the process either separately or together.
