Definitions

  • ABSTRACT 30 F A li tio Pri Da 1 orelgn pp ca n onty ta Crinkle-preventer for textile yarns comprising a sup- Mar. 12, 1971 Switzerland ..3677/7l ort and three bar arranged on the support so that one bar passes at a given angle between the other two [52] US. Cl ..57/l06 which two are parallel, the bars being formed of a [51] Int.
  • a crinkle-preventer may consist, for example, of a support with a cylindrical pin which may be fixed coaxially with the bobbin axis on its head, on the free end of which a ring is mounted freely movable between two limiting collars.
  • the yarn is fed at a certain angle, passed between the support and the ring and again drawn off at a certain angle.
  • This crinkle-preventer suffers from the disadvantage that it must be removed from the old bobbin and fixed on the new bobbin on every bobbin changing operation.
  • knotting of the yarn end of the emptying bobbin with the yarn end of the new bobbin is not po'ssible since, as long as the crinkle-preventer is not fixed on the new bobbin, the yarn end of the new bobbin cannot rotate and would be torn off.
  • a crinklepreventer for textile yarns particularly of textured yarns, which is characterized in that, in an annular support with a slot therein, three bars of circular cross-see tion are fixed, two of which are arranged in parallel at a certain vertical distance from each other and the third passing between the two former bars without any contact and crosses them at an acute angle, and in that each of the three bars, in addition to a straight part, is formed with an S-shaped bent end part.
  • the support may be of oval or any other form. It may consist of metal or of synthetic material and be formed by a base plate and a cover plate.
  • the bars may consist, for example, of polished spring steel, of a sintered ceramic material or of other alloys; and the diametrally arranged bars may cross at an angle of between 5 and 30.
  • FIG. 1 is a top plan view of the base plate of an example of the crinkle-preventer of the present invention
  • FIG. 2 illustrates an arrangement of the crinklepreventer above a yarn cop in lateral view
  • FIG. 2A is a detail perspective view of part of the structure of FIG. 2 and is used to illustrate a yarn path
  • FIGS. 3-5 are cross-sectional views taken along line C-C of FIG. 1 illustrating details of the crinklepreventer in different oblique positions.
  • the bottom plate 1 of the support is shown as having an oval shape, the base plate consisting of aluminum and being of a thickness of the order of 2 mm.
  • the base plate consisting of aluminum and being of a thickness of the order of 2 mm.
  • three bars 2, 3 and 4 of circular cross-section of polished spring steel, are fixed. All three bars have diameters of 0.5 mm, and each has an S-shaped bent end part (2, 3, 4) serving as a stop member for the yarn, and is of spiral shape at both ends.
  • the spirals are removably fixed in recesses 7, 7;
  • the bars 2 and 4 are arranged in the support diametrally and in parallel with one another, but are separated by a vertical distance which corresponds to the bar diameter and cross the bar 3 which is passed diametrally between them at an angle at here shown to be of about 10.
  • the angle a may be varied if necessary between 5 and 30 by displacing one spiral-shaped end of each of the bars 2, 3, 4, into corresponding recesses 7", 8", 9" of the base plate 1.
  • the support 1, l is formed with a lateral slot 5 for inserting the yarn, executed as a selfthreader, one edge 5' of the slot being rounded to facilitate insertion of the yarn.
  • thev support 1 has three bores 6, 6', 6" serving to fix the crinkle-preventer on the bobbin frame of the processing machine by means of screws 13.
  • FIG. 2 illustrates the arrangement of the crinklepreventer in oblique position above the yarn bobbin 114, its connection to the bobbin frame being not shown.
  • the oblique position of support ll, 1' is chosen so that the yarn 12 can be positioned on the bars 2, 3, 4 along the distance A B, according to its tension.
  • the middle plane of support 1, 1' accordingly, forms an angle ,6 with the central axis E of the bobbin support 15.
  • the crinkle-preventer can be arranged so that the central axis of the support 1, ll is slightly displaced with respect to the central axis E of the bobbin support 15. The amount of this displacement depends on the behavior of the yarn 12 while passing through the crinkle-preventer, and positioning of the yarn along the distance A B.
  • the yarn 12 drawn off from the bobbin 14 is inserted into the support 1, 1' through the slot and thus passed around the bars 2, 3 and 4, as shown in FIGS. 3-5.
  • the yarn is fixed on the support 1, 1 during drawing-off in the knee A of bars 2, 4 and, depending on the tension, oscillates between the knee A and the crosspoint B of the bars, crinkles being thereby eliminated.
  • the yarn 12 is fed to the processing machine over the deviation member 16.
  • the extent of dissolution of crinkles may be adjusted by choosing the oblique position of the crinkle-preventer to obtain the most advantageous results.
  • the central plane D-D of support 1, 1' is declined around its central axis C with respect to the central axis E of the bobbin support 15, the angle B being 90.
  • the bars 2, 3 and 4 thereby apply a relatively low tension to the yarn.
  • the central plane D--D of support 1, 1' is inclined, with respect to the central axis E of the bobbin support 15, by an angle B of 120 to the right or to the left, wherefrom a large deviation of the path of the yarn 12 results.
  • the central plane D-D of support 1, 1' is inclined by an angle B of the order of 130 in respect of the central axis E of the bobbin.
  • the inclination of themiddle plane D--D with respect to the axis E by the angle B may in any case occur to the right or the left, depending on whether the yarn is S or Z twisted.
  • the crinkle-preventer of the present invention may, in certain cases, also be used as a yarn-brake when the yarn runs off a bobbin irregularly.
  • a crinkle-preventer for textile yarns having a torque characterized by sppport means provided with a slot, three bars (2, 3, 4) ixed to said support, two of said bars (2, 4) being spaced from each other, the third bar (3) passing between the two first-mentioned bars without contact with same and crossing them at an acute angle, each of the three bars being formed with a straight shank and a curved end part (2', 3', 4').
  • a crinkle-preventer according to claim 1 characterized in that the support is of oval shape.
  • a crinkle-preventer characterized in that the support consists of a base plate (1) and of a cover plate (1') of equal shape and size.
  • a crinkle-preventer characterized in that the ends of the bars (2, 3, 4) are of spiral shape and are fixed in corresponding recesses (7, 7'; 8, 8 9, 9') ofthe base plate (1).
  • a crinkle-preventer characterized in that the spiral shaped bar ends may be fixed in different recesses in said support means in order to change the angle at which the third bar crosses the first two bars.
  • a crinkle-preventer according to claim 1 characterized in that the bars consist of polished spring steel.
  • a crinkle-preventer according to claim 1, characterized in that the acute crossing angle of the diametrally arranged bars is between 5 and 30.
  • a crinkle-preventer characterized in that said slot in the support means is in the shape of a self-threader for the yarn and has a rounded edge (5) to facilitate insertion of the yarn.
  • a crinkle-preventer according to claim 1, characterized in that said two bars (2, 4) are parallel to one another.
  • a crinkle-preventer according to claim 1 characterized in that said bars are of circular cross-section.
  • a crinkle-preventer according to claim 1 characterized in that said curved part of said bars is S- shaped.
  • a crinkle-preventer for textile yarns having a torque characterized by support means provided with a slot, three bars (2, 3, 4) fixed to said support, two of said bars (2, 4) being spaced from each other, the third bar (3) passing between the two first-mentioned bars without contact with same and crossing them at an acute angle, each of the three bars being formed with a straight shank and a curved end part (2', 3', 4), and means mounting said crinkle-preventer relatively to a yarn supply package whereby the horizontal plane of said support is inclined with respect to the central axis of the supply package.
