Definitions

  • the tape is fed to the winding guide in a generally axial direction from a let-01f guide and at a tension such that the twist is applied in a controlled manner represented by localised folds to give a package from which the tape can be unwound over-end in a twist-free condition.
  • Synthetic plastics such as polypropylene and polyethylene may be produced in strip form by extruding the material as a sheet, slitting the sheet into narrow strips and then stretching the strips so as to align the molecules along the length of the strips.
  • the stretching greatly enhances the strength of the material in a longitudinal direction to give a strip material referred to as a tape suitable for weaving on a loom.
  • the weft has a certain amount of twist inserted into it at irregular intervals and this has a deleterious effect on the cover of the cloth thus woven.
  • the weft is drawn from a cop or pirn, the diameter of which is limited to about 1%". There is no particular problem in winding such a cop or.
  • a similar problem of twist insertion relates to the warp supply, namely, in the beaming of the tape intended for use as the warp.
  • a very large number of separate tapes needs to be drawn from packages mounted in a creel.
  • the problem can be solved by using a spool with a sideways let-off but this eliminates the possibility of tag-ending the packages which is highly desirable and which is only possible with over-end withdrawal.
  • a synthetic plastic tape drawn from a controlled speed supply source is formed into a package by winding the tape on a nonrotary support by means of mechanism comprising a guide for the tape which is driven round the axis of the support, so that in this way one turn of twist is applied to the tape for each revolution of the guide.
  • the tape is fed to the winding guide in a generally axial direction from the let-off guide at a tension such that the twist is applied in a controlled manner.
  • the effect of the insertion of twist during winding is that if the tape is subsequently unwound from the package over the same end as that from which is was wound the outcome is to remove the twist applied during Winding and to give a substantially untwisted strip.
  • a package wound in accordance with the present invention may be used either as a stationary weft supply for a loom or, for example, in a creel for the beaming of the warp supply and overcomes the difficulty referred to above. In other words it is possible to use over-end withdrawal with the advantages of tag-ending the packages but without the disadvantage of a twisted tape in the final product.
  • a slipping drive is preferably achieved by transmitting the drive through a slipping clutch, but the slip may occur in the source of the drive itself, e.g. an air motor. Since the linear speed of the tape remains substantially constant during winding, the rotary speed of the winding guide must be varied with changes of diameter of the package. The drive to the guide must, of course, allow for this.
  • the tape After leaving the let-off guide, the tape passes to the rotary mechanism and its first point of contact with the latter may either be the winding guide or some intermediate point. It is found that if the distance between the let-off guide and the contact point is kept relatively short this assists in maintaining regularity of the twist.
  • Each winding revolution of the tape causes it to be pressed against the let-off guide and thus to be creased as a result of this pressing action in combination with the tension in the tape, thereby precreasing the tape at intervals corresponding to each revolution of winding.
  • the twist in such a way that it is represented in the resultant pack-age by localised folds spaced apart by relatively long lengths of flat or untwisted tape.
  • the term relatively long is meant that at least 50% of the total length of the tape is untwisted, that is to say, is flat and has no twists or folds in it.
  • the folds may be considerably more localised than this so that a high proportion of the total length of the tape remains in an untwisted form. This is of importancefor two reasons. In the first place once twist has been inserted in a tape and has been converted into a fold by the winding process there is a likelihood that the mark produced by the folding operation will remain even after the tape has been untwisted. By ensuring that a high proportion of the total length of the tape is unfolded the overall appearance of the tape is improved.
  • a further advantage of localising the folding act-ion is that the lines of the folds are made at a rather greater angle to the axis of the tape rather than nearly parallel to the length of the tape as would be the case if the folds were more extensive. The more nearly a fold line is parallel to the length of the tape the greater the risk of fibrillation and this is an added reason for localisation of the folding action.
  • Apparatus for winding a package in accordance with the method previously set out comprises a mounting for a stationary support for thepackage, a let-off guide mounted generally axially of the support, mechanism for driving a winding guide round the axis of the support, and for producing relative transversing movement between the guide and the support, and means for maintaining a suitable tension in the tape as the diameter of the package varies.
  • the means for maintaining the tension may take any of the forms previously described.
  • the rotary mechanism for the winding guide most conveniently takes the form of a flyer having the winding guide at or close to its lower edge and a contact point for the tape close to its top, which may be constituted by a bearing point on the shoulder of the fiyer.
  • the guide may be mounted on a ring which encircles the package to be wound and which is then driven to cause the guide to move around the axis of the stationary support and thus to carry out the required winding action.
  • FIGURES 1A and 1B together show a complete production line including an extruder, stretching and stabilizing apparatus and finally winding apparatus;
  • FIGURE 2 is a sectional view of an individual winding head
  • FIGURE 3 is a perspective view with part broken away of a flyer forming part of the Winding head of FIG- URE 2;
  • FIGURE 4 is a diagrammatic view of a length of tape unwound from a package produced on the winding head of FIGURE 2;
  • FIGURE 5 shows parts of FIGURE 4 to an enlarged scale illustrating the effect of the folding action and the subsequent removal of the fold.
  • FIGURES 1A and 1B The majority of the components in the production line shown in FIGURES 1A and 1B are quite standard in themselves and require no detailed description. The figures are included, however, to illustrate the facility with which tapes produced by means of standard equipment may be wound in accordance with the present invention. .Turning first to FIGURE 1B the tapes shown as 1 emerge from an extruder and slitting unit 2 and then pass around a series of stretching rollers 3 which may, for example, stretch them by a factor of 7:1. After stretching, the tapes pass through the stabilisation ovens 4 and around stabilising rollers 5. From there they pass to creel bars 6 fitted with a number of dividing pins 7 to space the individual tapes apart.
  • FIG. 1B Components of the apparatus shown in FIGURE 1B are all standard while the apparatus shown in FIG- URE lA consists of a winding frame or frames indicated generally as 19 which comprises a multiplicity of winding heads 8 to wind the tapes coming from the extruder which in a typical example may be 104.
  • the particular winding machine shown in FIGURE 1A is double sided for convenience.
  • FIGURE 2 shows details of an individual winding head 8.
  • Each head comprises a tubular flyer 12 shown in more detail in FIGURE 3.
  • Each flyer 12 is located on a spigot 13 on the upper end of a driving spindle 14. This spigot provides a driving connection to the flyer 12 but allows the flyer to be lifted off for the dotting of a finished package shown as 15.
  • a spindle 14 is mounted in a footstep bearing 18 and passes upwardly through bearings 19 in a reciprocating rail 20.
  • the bearing 19 is mounted within a tube 21 which reciprocates with the rail and which carries a second bearing 22 for the spindle 14.
  • the spindle 14 is driven through a friction clutch arrangement indicated generally as-25.
  • This comprises a belt pulley 26 which is driven by a belt (not shown) from a common source of drive for the machine as a whole.
  • the pulley 26 is free to turn on the spindle 14 and engages a ring of friction pads 28 mounted on a flange 29 secured to the spindle 14 at 30.
  • the friction pads 28 can be adjusted in a radial direction so as to vary the frictional drive between the pulley 26 and the flange 29 and hence the spindle 14. This provides the required control over the tension in the tape being wound.
  • EA non-rotary support 34 for the package 15 is removably fitted on a tube 35 having a radially extending arm 36 which is releasa-bly attached at 37 to a vertically extending bar 38.
  • This bar reciprocates with the rail 20 to provide the relative traversing motion between the flyer 12 and the package 15.
  • the bar 38 is adjustable in relation to the rail 20 so as to provide the necessary builder motion for the shaping of the ends of the package 15.
  • one face of the bar 38 is formed as a rack cooperating with a pinion 39 mounted on a shaft 40 which also reciprocates with the rail 20 and is given successive small angular movements as the rail reciprocates so as progressively to lower the bar 38 and hence the package 15 in relation to the rail 20.
  • the tape shown as 1 passes from the respective creel bar 6 to a let-off point on the axis of the flyer 12.
  • This let-off point is constituted by a small freely rotatable roller from which the tape passes to a second control point defined by a bearing surface 46 on the shoulder of the flyer 12. From there the tape passes downwardly to a guide 47 constituted by a rotary runner and from there it is wound onto the stationary tube 34 so as to build up the package 15.
  • the tapes 1 will all reach the winding machine 9 from the extruder at a substantially constant speed and to allow for this the rotary speed of each package 15 needs to be reduced correspondingly as the package builds up. This result is achieved automatically by slipping of the clutch 25.
  • the tension in each tape is controlled by adjustment of the clutch 25 as previously described.
  • FIGURE 3 the tubular wall of the flyer 12 is interrupted by access windows 50 and 51 which also lighten the construction since as previously mentioned the flyer as a whole needs to be removed for dofling.
  • the guide 47 runs on a stud 55 fixed to a plate 56 carried on the bottom skirt of the flyer, part of which is broken away to show the path of the tape onto the package 15.
  • the flyer comprises a light arm 58 which is pivoted about a vertical axis defined by a tube 59 passing through the stud 55. Part of the arm 58 passes up the tube 59 and is held at its upper end by a stopper 60.
  • the other end of the arm 58 is formed with a short extension 62 over which the tape passes immediately before being laid on the package 15.
  • the extension 62 is formed with tape engaging surface, Le. a small notch 63, which ensures accurate location of the tape 1 in an axial direction in relation to the package 15. The self threading operation automatically lays the tape in the notch 63.
  • the arm 58 is freely pivoted and is merely held against the surface of the package by the tension in the tape.
  • a biassing force so as to counteract the effect of the centrifugal force on the arm 58 and thus to assist in holding the extension 62 against the surface of the package.
  • This may be provided, for example, by a spring or by'a counterweight mounted so that the centrifugal force on it tends to swing the arm 58 inwardly towards the package 15.
  • the tape passes over the roller in a fiat condition, being controlled laterally by the flanges of the roller, and twist is immediately inserted as shown in FIGURE 3.
  • the tape In the angular position of FIGURES 2 and 3 the tape continues in the same general direction after leaving the roller 45, but by the time the flyer has turned through half a revolution 21 short length of tape (including the twist shown immediately following the roller 45 in FIG- URE 3) has been lead around the underside of the roller 45 and pressed against it by the tension in the tape. Inspection of the apparatus during operation shows that the result of this is for the twisted tape to be creased as a result of pressure against the roller.
  • roller 45 had a diameter of A"
  • the vertical distance between the roller 45 and the bearing surface 46 was 3%;
  • the tension in the tape was 150 grams and the cone angle was approximately 60 as mentioned above.
  • FIGURE 4 shows diagrammatically the effect of the localisation of the folding action. 70 and 71 represent adjacent folds and these are separated by a much greater length 72 of unfolded tape. Even if the folding is not as highly localised as shown in FIGURE 4 the provision of the control region provided by the points 45 and 46 nevertheless leads to considerable uniformity in the folding action.
  • FIGURE 5 This folding action is illustrated to a considerably larger scale in FIGURE 5.
  • 73 shows a pair of closely spaced folds representing one complete turn of twist and corresponding to either 70 or 71 in FIGURE 4. It will be seen that the fold lines are at an appreciable angle to the axis of the tape so that the folding is localized and thus leads to the relatively great unfolded length 72 of FIGURE 4.
  • the twist is progressively taken out to leave an untwisted tape as previously described.
  • FIGURE 5 shows the untwisted tape exhibiting the lines resu1ting from the folds indicated at 73. Owing to the fact that these lines are localized they have no marked adverse elfect on the appearance of the tape and moreover their angle to the axis of the tape avoids any serious danger of fibrillation which might otherwise occur with fold lines more nearly parallel to the axis of the tape as would be the case if the folding were not localized.
  • a method of forming a package of synthetic plastic tape drawn from a controlled speed supply source comprising feeding said tape in a generally axial direction from a let-off guide to a winding guide, driving said guide round the axis of a non-rotary support, while a relative axial traversing motion takes place between the said guide and said support, whereby to wind said tape on said support and to apply one turn of twist for each revolution of said guide, and controlling the tension in said tape such that the twist is applied in a controlled manner.
  • Apparatus for winding a package of synthetic plastic tape drawn from a controlled speed supply source comprising a mounting for a stationary support for the package, a let-off guide mounted generally axially of said support, a winding guide, mechanism for driving said winding guide around the axis of the support, a contact surface on said rotary mechanism displaced from the axis of rotation, whereby to engage said tape at an angle as it passes from said let-off guide to said winding guide, the distance between said let-off guide and said contact surface being short in relation to the distance between said let-off guide and said winding guide, means for producing a relative traversing movement between said winding guide and said support, and means for maintaining a suitable tension in the tape as the diameter of the package varies.
  • Apparatus according to claim 8 including a constant speed drive and a slipping clutch.
  • said rotary driving mechanism is in the form of a flyer having said winding guide at or close to its lower edge and having a contact point for engaging the tap close to its top.
  • said winding guide is constituted by a rotary runner having its lower surface unobstructed so that the fiyer is selfthreading, and said arm is so shaped and positioned relatively to said winding guide that the tape is automatically correctly located on the tape engaging surface as a result of this self-threading operation.
  • Apparatus according to claim 15 in which the tape engaging surface of said arm is substantiall straight in a direction transverse to the flow of the tape.
  • a method of forming, on a non-rotary support, a package of synthetic plastic tapedrawn from a controlled speed supply source comprising feeding said tape outwardly at an angle from a let-off point on the axis of said non-rotary support via an intermediate contact surface offset from said axis to a winding member and thence to a winding-on point on said support, said contact surface being spaced from said let-01f point by a distance which is short in relation to the distance between said let-off point and said winding-on point, driving said winding member and said contact surface round the axis of said support while a relative axial traversing motion takes place between said member and said support, whereby said tape follows a conical path between said let-01f point and said contact surface under controlled tension tending to press said tape against said contact surface and, due to the proximity of said contact surface, is creased at said let-off point during part of each revolution to produce localised folds in said tape.
