Definitions

  • the invention relates to a foulard with a wrapping roller for a textile material web to be treated and a trough for receiving a liquor which is taken up by the rotating wrapping roller on the trough and via a doctor blade which abuts the circumference of the wrapping roller and wipes off the excess liquor the material web is transferred, the doctor blade having a large number of recesses lying next to one another on its contact surface abutting the wrap-around roller and being held by means of magnetic force over its length for abutment against the circumference of the wrap-around roller.
  • the wrap roller cannot adequately meet this condition, due to its wall thickness being too small.
  • the weight of the roller alone results in a deflection which interferes with the necessary, uniform application of the doctor blade on the circumference of the wrapping roller.
  • the wrapping roller can easily be mechanically damaged, resulting in pressure points, etc., which can also be applied to the doctor blade unevenly.
  • the squeegee is attracted by magnetic attraction in the direction of the inside of the wrapping roller, it is not possible to increase the stability of the roller, for example by increasing the wall thickness or a thicker rubber pad, because the magnetic force is square with the distance between the in the wrap roller and the doctor blade decreases. For this reason, the thickness of a rubber pad that may be provided cannot be increased.
  • the invention is therefore based on the object of developing a foulard of the type mentioned in such a way that, using the principle described, the use of a doctor blade with a plurality of adjacent recesses, which is held by magnetic force on the circumference of the wrapping roller, is minimal Fleet order across the entire width of the relevant web.
  • the invention is characterized in that the squeegee is designed as a magnetic squeegee and is pressed with the aid of a magnetic bar, which is provided parallel to it on its side facing away from the wrapping roller, with magnetic repulsive force to the circumference of the wrapping roller covered with an elastic material becomes.
  • the jacket of the wrapping roller can therefore be made as strong as the particular circumstances require, in particular to reliably prevent any bending of the wrapping roller jacket.
  • the jacket of the wrapping roller, including the coating can therefore be chosen so strongly that the squeegee rests without gaps over its entire length with the elevations between its depressions on the circumference of the wrapping roller, whereby it is pressed against the circumference of the wrapping roller over its entire length by means of magnetic force.
  • the magnetic squeegee is preferably produced from a rotatably mounted tube with an engraved surface, into which permanent magnets with pole shoes located between them are inserted, which are clamped by means of a continuous mandrel.
  • the mandrel holds the permanent magnets axially fixed with their pole pieces.
  • the doctor blade is non-magnetic and made of magnetizable material, i.e. Chrome, if the doctor blade is magnetic according to the invention, i.e. it is a magnetic squeegee.
  • the magnetic squeegee can, however, also be designed as a polygonal tube with comb-shaped recesses in one side, with permanent magnets with pole shoes also being introduced into the tube next to one another and fixed there in a suitable manner.
  • the magnetic bar has magnetic elements next to each other, which lie opposite poles of the same name of magnetic elements of the magnetic doctor.
  • the magnetic elements of the magnetic bar can be permanent magnets or electromagnets. When using electromagnets there is the advantage that the magnetic force can be switched on and off as desired, while no separate power supply is necessary when using permanent magnets.
  • the distance between the magnetic squeegee and the magnetic bar should be infinitely adjustable in order to be able to regulate the pressing force accordingly.
  • the magnetic bar is mounted in a guide in such a way that the magnetic bar can be moved out of the effective range of the magnetic doctor blade, a cover made of non-magnetic being removed during this displacement Pushes material in front of the magnetic bar.
  • the cover should have a thickness such that the magnetic squeegee can no longer be attracted to the magnetic bar with magnetic force.
  • the magnetic squeegee is fastened to a swivel bar, a sleeve made of non-magnetic material being provided which can be pushed onto the magnetic squeegee.
  • a sleeve made of non-magnetic material which can be pushed onto the magnetic squeegee.
  • This is, for example, a sleeve slotted in the axial direction, which can be pushed onto the magnetic squeegee when the magnetic squeegee is pivoted away from it.
  • the thickness of this sleeve is also selected so that the magnetic squeegee and the magnetic bar can no longer adhere to one another with magnetic force.
  • a wrap roller 1 is provided which rotates in the direction of arrow 2.
  • the jacket of the wrapping roller is of sufficient strength and is provided with a rubber covering.
  • a liquor is to be applied very evenly with minimal liquor consumption to a web of material 3 which is passed through the foulard in the direction of arrow 4.
  • the fleet is in a trough 5.
  • the material web, coming from a first guide or supply roller 6, is guided over further guide rollers 7, 8, 9 and 10, as shown in the drawing in FIG. 1.
  • the web is therefore between the guide rollers 9 and 10 on the circumference of the wrapping roller 1.
  • a lay-on roller 11 can be provided between these two guide rollers, the distance of which from the wrapping roller 1 is preferably adjustable. Several such adjustable lay-on rollers can also be provided.
  • the guide rollers can also be adjustable, as indicated in position 7.
  • the wrapping roller 1 dips into the trough 5 and, when it rotates, takes up the liquor. Excess liquor is removed during the rotation of the wrapping roller by a magnetic doctor 12, which is pressed against the circumference of the wrapping roller.
  • the magnetic doctor blade has a large number of depressions next to one another, as can be seen from FIGS. 4 and 5.
  • the depressions are 0.15 mm deep, for example. If they are designed in the manner of a thread according to FIG. 4, this has, for example, a pitch of 0.5 mm.
  • the squeegee is magnetic.
  • it is designed as a tube into which permanent magnets 13 and pole shoes 14 are alternately inserted (cf. FIG. 2).
  • the pole pieces alternately receive a different magnetization, which is identified by N or S.
  • FIG. 2 also shows that the north poles and south poles of the magnetic squeegee lie opposite north poles and south poles of a magnetic bar 15. It is shown in the drawing that these are somewhat wider than the north and south poles of the magnetic doctor; but they can also be the same width or a little narrower. It is important that a south pole is opposite a south pole and a north pole is opposite a north pole.
  • Fig. 3 shows the construction of the magnetic bar 15. This consists of a rod 16 which is held on a U-shaped bracket 17. An approximately semi-cylindrical recess is provided in the center of the rod, into which semi-cylindrical magnetic elements 18 are also embedded next to one another.
  • the magnetic elements are either permanent magnets or electromagnets.
  • the magnetic elements are held by holding rods 19 which are laterally on the rod 16 are screwed and each have a shoulder with which they overlap the half-shell-shaped magnetic elements.
  • FIG 3 also shows the magnetic squeegee 12 and reveals that the magnetic elements 18 of the magnetic bar 15 form a half-shell shape on the circumference of the magnetic squeegee 12 at an adjustable distance.
  • Fig. 2 shows the bearing of the doctor blade, which in this embodiment according to Fig. 4, i. is rotatable, mounted.
  • the doctor blade is axially fixed by the steps shown in the drawing, so that poles of the same name always lie opposite one another.
  • the trough 5 can be tilted down for cleaning and repair purposes, as indicated.
  • the magnetic bar 15, as also shown in FIG. 1 can be displaced radially outward by the path 20.
  • a cover 21 is automatically pivoted downwards in front of the magnetic bar and thereby protects it.
  • the magnetic squeegee 12 can also be switched off by the wrapping roller.
  • the magnetic squeegee including its bearing protector, is also displaced radially outward by a few centimeters and can then be pivoted away easily by means of a swivel bar 22, which has a suitable receptacle for mounting the magnetic squeegee, as indicated in the drawing.
  • a sleeve also made of non-magnetic material, is pushed over the magnetic squeegee to prevent it from coming into contact with iron parts.
