Definitions

  • the invention relates to a combing machine with a tear-off device for tearing off fiber beards from a reciprocating pliers and soldering the torn off fiber beards to form a nonwoven web.
  • Such a tear-off device in which the soldering takes place only after the pair of tear-off rolls, e.g. as described in US-A-1 922 030 has the advantage that the tear-off rollers can rotate continuously, that is, do not have to be rotated back and forth with a mit step movement. As a result, higher working speeds or lower gear loads can be achieved.
  • the two soldering rollers In the tear-off device according to the aforementioned US-A-1 922 030, however, the two soldering rollers must be moved back and forth together towards and away from the tear-off rollers and simultaneously rotated at changing speeds.
  • the object of the invention is to design the tear-off device in a combing machine of the type specified at the outset in such a way that back and forth movements in it can be avoided as far as possible.
  • a simple structure of the tear-off device and the drive for the same should be made possible.
  • the object is achieved in the combing machine according to the invention in that the two soldering rollers are set up to clamp the nonwoven web only during part of each reciprocating movement of the pliers.
  • soldering rollers the comb web only during the mentioned Transport part of each reciprocation of the pliers; it is therefore possible to drive one of the soldering rollers continuously at a constant speed, the peripheral speed of this soldering roller being approximately the same size (or slightly greater than) the peripheral speed of the tear-off rollers.
  • At least one of the soldering rollers, expediently the driven one can, like the tear-off rollers, be mounted essentially fixed to the frame.
  • the round comb shaft 1 which is rotated continuously at constant speed during operation of the combing machine, carries a round comb roller 3 with a round comb segment 4 equipped with combing needles or combing sets Crimping frame 6 is articulated.
  • the front end of the collet frame 6 is articulated on front supports 7 which are pivotable about the axis of the round comb shaft 1.
  • the lower clamp frame 6 carries a lower clamp plate 8, the front edge of which cooperates with the lower edge of a upper clamp plate 9, which is held by upper clamp arms 10 which can be pivoted with respect to the lower clamp frame 6.
  • the pliers 6, 7, 8, 9, 10 are fed fiber material to be combed in the form of a cotton wool W.
  • Fig. 1 the pliers is shown in a retracted, closed position, the front end portion of the wadding W is clamped between the pliers plates 8 and 9, and the fiber beard protruding from the pliers is combed out by the circular comb segment 4.
  • the pliers 6, 7, 8, 9, 10 are then moved against an advanced, open position in a tear-off device, as shown in FIGS. 2 and 3.
  • the tear-off device contains a lower tear-off roller 11 which is mounted on the frame in the combing machine and is rotated continuously at a constant speed in the tear-off direction, and an upper tear-off roller 12 which is pressed against the lower tear-off roller 11 by a load of force and is carried by the latter.
  • the tear-off device contains an upper soldering roller 13 which is mounted on the frame in the combing machine and is also rotated continuously at a constant speed in the tear-off direction.
  • the upper soldering roller 13 as indicated in FIG.
  • a lower soldering roller 16 interacts with the upper soldering roller 13 and is mounted in levers 17 which can be pivoted about an axis 18 fixed to the frame.
  • the levers 17 are pivoted up and down by a drive, not shown, so that they press the lower soldering roller 16 against the upper soldering roller 13 only during part of each reciprocating movement of the pliers 6, 7, 8, 9, 10, as in FIG The following will be explained.
  • the pliers 6, 7, 8, 9, 10 have reached their front end position, the front end of the fiber beard previously combed by the circular comb segment 4 is gripped by the tear-off rollers 11, 12.
  • the tear-off rollers 11, 12 then tear the fiber beard from that lying in the pliers Wadding off cotton wool, the rear end of the fiber beard being pulled through a fixed comb 19 and combed out by the latter.
  • Fig. 4 shows another embodiment of a tear-off device which can perform the functions described in the combing head.
  • the tear-off rollers 11, 12 are of the same design as described with reference to FIGS. 1 to 3, the roller 11 is driven continuously in the tear-off direction during operation.
  • the lower soldering roller has a roller body 21 which is fixed to the frame and is continuously driven in the tear-off direction during operation and which carries three separate peripheral segments 22.
  • Each circumferential segment 22 only clamps the comb web against the upper soldering roller 13 during part of a reciprocating movement of the pliers of the combing head, so that the comb web is only transported during this part of the pliers movement, as described with reference to FIGS. 1 to 3.
  • the position according to FIG. 4 corresponds to the position according to FIG.
  • the transport of the ridge fleece begins.
  • the transport of the crest fleece stops again when the rear end of the crest fleece is at a distance behind the clamping line of the soldering rollers 13 and 21, 22, as in FIG. 1, at this moment the upper peripheral segment 22 in FIG. 4 leaves the upper soldering roller 13 .
