Definitions

  • the present invention concerns a device to be applied downstream of a wool card with double comber so as to allow collecting, in a fully automatic way, the webs fed from the combers towards the centre of the machine, and inserting said webs onto a conveyor feeding the webs towards a further operating machine positioned downstream of the combers, particularly a drawing frame.
  • this operation is carried out manually: when the card is set working and a web of carded fibres is formed on the combers, and when, more exactly, the web stripping combs start to remove the fibers web from the combing rollers, a machine operator provides to collect the web towards the centre and convey it manually towards an outlet conveyor.
  • the object of the present invention is to propose a device allowing, in a fully automatic way, both to collect the webs and to introduce them onto the outlet conveyor, thus freeing the operator from the problems and risks connected with these operations. Said object is reached with the characteristics pointed out in claim 1.
  • Fig. 1 illustrates the end portion of the card, and precisely its carding swift 1, followed by two combing rollers, an upper roller 2a and a lower roller 2b, each provided with its own web stripping comb, respectively 3a and 3b.
  • references followed by the letter a refer to the upper combing unit, while the references followed by the letter b refer to the lower combing unit.
  • a collecting channel Ca, Cb is positioned just under each web stripping comb 3a, 3b, said channels extending parallely to said combs, namely to the rotation axis of the combing rollers.
  • Each collecting channel is delimited by a pair of tipped sideboards 4a, 4a' and 4b, 4b', forming a throat to pick up the web Va and Vb (see also fig. 2) which, being stripped by the web stripping comb, freely drops downward.
  • the bottom of the channel Ca, Cb is formed by the belt 5a, 5b of a horizontal conveyor. More precisely - as clearly shown in fig. 2 - each of said conveyors is formed by two belt sections, each extending from one end of the conveyor towards the center and moving in opposite directions: in this way, the upper belts 5a, 5a' and respectively the lower belts 5b, 5b' of each conveyor all move towards the centre - as indicated by the arrows - conveying and thus collecting at the center the two webs of carded fibers. This web transport towards the centre is diagrammatically illustrated by the dotted lines Va' and Vb' in fig. 2.
  • the two driving cylinders Ra of the belts of the conveyors are sufficiently spaced apart to allow inserting the web collected at the centre and subsequently dropping the same towards the outlet.
  • the web - now indicated by Va'' and Vb'' - moves down towards an auxiliary conveyor, positioned below said central collecting point and arranged perpendicularly to the conveyor 5a, 5b; each auxiliary conveyor is formed by a pair of superposed beltss, respectively 6a, 6a' and 6b, 6b'.
  • each auxiliary conveyor - as clearly illustrated in fig. 1 - the bottom belt 6a or 6b is longer and easily collects the web Va''or Vb'' gathered at the centre, while the top belt 6a' or 6b' is shorter and its essential function is to press the gathered web against the bottom belt.
  • the upper auxiliary conveyor formed by the belts 6a, 6a', conveys the web Va'' directly towards the outlet of the device, for example towards a successive drawing frame.
  • the lower auxiliary conveyor formed by the belts 6b, 6b', conveys the web Vb'' towards a further conveyor formed by the pair of belts 7, 7', which, being positioned oblique - almost verticalwise - and always keeping the web Vb'' in a pressed condition, conveys it towards the top, so as to be rejoined with the web Va'' in correspondence of the outlet of the device.
  • the device according to the present invention allows - in a fully automatic way and without requiring any manual operations - to collect the two webs Va, Vb, fed from the two combing rollers 2a, 2b, each towards the centre of the carding unit, and then join them together into a single bundle to be conveyed towards the drawing frame.
