Definitions

  • ABSTRACT A method and of producing a slide fastener tape and an apparatus therefor for guiding back and forth a fastener member-forming warp in a shed forming movement through a weaving plane to form a row of fastener members, feeding the profile strand within a range of a stop point about a loop-forming mandrel, the latter held at one end and binding the profile strand by a weft thread and the shed forming movement caused by feeding the latter about the mandrel.
  • the present invention relates to a method of and an apparatus for the production of a slide clasp fastener tape by weaving.
  • the present invention amounts to an improvement and further development of the invention disclosed in German Pat. No. 2,023,005 (German Pat. application No. P 23 0051-26) where within the range of the weaving location for the formation of the fastener members a thread forming a member reciprocates to form a shed and thereby is fed about a loop forming mandrel and the band weaving is bound by a weft thread.
  • the present invention improves and simplifies the method of production of a slide clasp fastener by weavmg.
  • the profile strand is moved upwardly and downwardly forming a shed about the securing end of the mandrel, through a weft insertion plane which is determined by the working stroke of the weft insertion device, so that this profile strand is gripped by the weft thread and can be bound in the fabric; on the other hand, the profile strand during this movement is wound simultaneously about the mandrel, whereby on the fell there are created loops of the profile strand, which form the members of the fastener member row.
  • this profile strand moves about the loop forming mandrel along the surface of a circular cone, the base circle of which has at its center point the securing end of the mandrel which is held there, while the apex of this cone lies at the fell.
  • the diameter of the base circle determines the spreaded width of the profile strand for its shed formation. Concerning the shed, there is an excellent diameter of the base circle of the cone, where the profile strand assumes the uppermost and the lowermost extreme positions during its formation. The diameter thereof crosses the insertion plane of the weft thread.
  • the profile strand is disposed with a sufficient spreaded width above and below, respectively, of the mentioned weft insertion plane, so that during the rotation along the circular cone, a crossing feature of the fabric between the profile strand and the weft thread is created.
  • the base circle of the cone is oriented very close to the fell, to permit the cone to be developed with an appreciable base circle by the profile strand. So that this dimensioning of the rotation does not create any difficulties, it is desirable, to permit the profile strand to develop thereby an inclined circular cone, the cone axis of which forms with the plane of the base of the base circle an acute angle, with the plane of the base circle being retained substantially parallel to the plane of the spreaded movement of the shed forming wrap thread. Since the base circle points in the direction of the warp threads, the remaining warp threads of the fabric do not hinder, by their arrangement, the rotation of the member forming profile strand.
  • the present invention is directed also to an apparatus for performing the above mentioned weaving method, where at the fell a loop forming mandrel is disposed for the formation of the fastener member row from a continuous profile strand.
  • a rotary driven shedforming-rotor in the removing direction of the fabric, in front of the fell, there is disposed a rotary driven shedforming-rotor.
  • a securing end of the loop forming mandrel is set in the axial range of the rotor, and does not bind into the fabric.
  • the rotor is formed eccentrically to its rotary axis with an opening, which turning about the mandrel, and through which is guided the profile strand in a spreaded direction.
  • the profile strand Upon rotation of the rotor, thus the profile strand is set at first through the weft insertion plane from a shed part in the oppositely disposed shed part and is simultaneously wound in loops about the mandrel at the weaving location.
  • the eccentrically arranged opening guides the profile strand, at one diametric position within the range of a warp thread group belonging to the lower shed and, at the other diametric position within the range of the warp thread group of the upper shed.
  • the loop forming mandrel is thereby suitably rotatably disposed on the rotor, so that upon its rotation the mandrel is not joined in rotation.
  • the loop forming mandrel does not participate in the shed formation, rather it is disposed always on the same side of the warp insertion plane, so that it does not cross with the weft thread. Since the rotor, which serves the attachment of the securing end of the loop forming mandrel, does not bind into the fabric, it thus does not require in addition to its rotary movement any further stroke.
  • the loop forming mandrel remains during the weaving process of the apparatus in an unchanged rest position so as not to project into the area of the working stroke of the weft insertion means as the shed fonning means.
  • the eccentricity of the thread guiding opening in relation to the rotary axis of the rotor must be large, which requires large diameters of the rotor. So that such large spacial formation does not render more difficult the arrangement of this structural part in the weaving machine, the rotor is formed as a circular disk and its rotary axis is disposed substantially perpendicularly to the plane of the spreading movement of the shed forming warp threads.
  • the drive of the rotor is effected suitably by peripheral teeth on the circular disk.
  • an additional running thread is joined, which is to. form the later member row insert and to permit winding this additional run thread jointly with the loop forming mandrel in the range of the fell by the member forming profile strand.
  • a compensating linking movement of the additional run thread relative to the member forming strand is performed, so that the rotation in the opposite direction which is created at this location for the linking at the fell is eliminated.
  • the additional run thread jointly with the member forming profile strand which is wound in loops, is gripped by the weft thread and bound in the fabric.
  • the weft thread grips the additional run thread, disposed now as an insert in the inner space of the winding, and presses by means of the latter, the rear winding parts of the member-forming loops of the profile strand to the desired extent into the marginal range of the fabric.
  • the marginal range of the fabric is, with its fabric threads, designed as a weave for circular goods, where the rear winding parts of the row of fastener members are worked into a desired extent from the weft thread. This process is enhanced by the auxiliary run thread.
  • the described method can be realized in a simple manner such, that in the shed forming rotor a nonrotating insert is provided, which insert carries the loop forming mandrel, which insert is equipped with a thread passage for the latter as an additional run thread, serving as later insert of the row of fastener members.
  • This insert is disposed suitably in the center of the rotor.
  • a rotary device is provided having a rotating thread guide means. The thread guide means of the rotary device runs synchronously with the rotation of the shed forming rotor.
  • Such thread guide means can comprise a winding-off drop, which is aligned coaxially with a storage spool of the additional run thread, and in which the winding-off drop is rigidly connected with a hollow shaft which is placed in movement by the weaving drive.
  • the member forming profile strand is guided by the inner space of the hollow shaft.
  • the reverse arrangement could be made, by. arranging the winding-off drop axially to the storage spool of the member forming profile strand, and the additional run thread is fed through the hollow space of the shaft, the storage spool of which lies further back in relation thereto.
  • auxiliary run thread jointly with the member forming profile strand is gripped by the fabric weft and is bound into the fabric
  • a thread guiding device between the fell and the insert which performs within the weaving cycle a lifting movement and thereby gets into weaving connection with the auxiliary run thread, so that the latter is transformed from its normal position in a shed part, as the lower shed, and where also the loop forming mandrel is disposed, through the weft insert plane, beyond in the oppositely disposed shed part, as for example, the upper shed.
  • a needle can be used, which moves within a cycle upwardly and downwardly in the direction of the shed forming spreading movement of the warp threads.
  • a groove can thereby be provided on the end face of the needle, in which groove, during the lifting movement of the needle, the additional run thread can enter, so as to be transformed into the opposite shed part. Since this thread guiding device grips only the additional run thread and, not the loop forming mandrel, only the additional run thread, and not the loop forming mandrel, is gripped by the weft threads and crosses with the latter by the formation of a fabric binding.
  • the weft insert plane itself so as to be adjustable as to its height, which plane being determined by the working stroke of the weft thread insert device, such that the additional thread, which is now not participating in a shed forming spreading movement of the remaining warp thread, is disposed alternately above and below the prevailing position of the weft insert plane. For this reason, there is provided for the thread passage in the center insert of the rotor, relatively to the engaging location of the loop forming mandrel, a sufficient distance, so that there is a sufficient spreading for the passage of the weft thread insert device between the additional run thread and the loop forming mandrel.
  • the weft insert takes place, for example, about the loop forming mandrel, yet above the additional thread. If the weft insert plane is set relative thereto into a higher position, the working stroke of the weft thread insert device is disposed now above the additional thread, as well as above the loop forming mandrel. This has the consequence that the additional run thread, and not, however, the mandrel, is gripped desirably by a weft and the remaining warp thread of the fabric has to perform relative thereto only a sufficiently high spreading movement for the formation of its shed, so that relative thereto, the height displacement of the weft insert plane does not play any role.
  • a further simple possibility for gripping of only the additional run thread (not of the mandrel) by the weft in the desired manner is an arrangement in which the exit location of the thread passage for the additional run thread is arranged in the insert eccentrically to its axis, so that between the loop forming mandrel, which is received in the range of the axis of the insert, and the additional run thread, there is created a sufficient spreading angle for the performance of the weft thread insert device.
  • the insert is thereby driven oscillatingly in the weaving circle.
  • the thread passage of the additional thread assumes in the insert, different height positions relative to the weft insert plane such, that the additional thread is brought from its one spread position, in which it belongs to the group of warp threads of the one shed part, through the weft insert plane into another spread position, in which it is arranged by the warp threads of the oppositely disposed other shed part.
  • the loop forming mandrel in the center insert is arranged suitably with less eccentricity, is rotatably mounted in the center of the insert, so that it assumes a rest position during the oscillation movement of the insert.
  • the rotary drive of the rotor,'with which the member forming thread is wound about the mandrel, as well as through the weft insert plane, is transformed from one shed part into another, and takes place continuously in the simplest case in one direction, so that as, a result thereby, a helical spring-like winding of the member forming profile strand is produced within the range of the fell.
  • No intermittent rotary movement has to be used therefor, rather it will suffice, if the rotor performs a continuous rotary movement, which is much easier to obtain.
  • rows of fastener members with a different winding form for example, in form of a spatial meander, can be produced, if the rotary drive of the rotor changes, correspondingly, in the cycle, in its rotary direction.

  • the additional thread follows at an equal distance and movement of the member forming thread 16, whereby in this range an opposite rotation of the threads is prevented.
  • FIG. 5 a rotor 47 with the omission of all other structural parts is shown. Corresponding numerals have been applied to indicate corresponding parts and the same explanations as stated before also apply.
  • the thread passage 59 for the additional thread 60 can now be sufficiently distant from the securing end 311 of the mandrel 60 in the insert 55, so that a spreading angle is achieved, which creates a sufficient intermediate space for the insert path of the weft thread needle 17.
  • the insert 55 rests during the rotation of the rotor disk 47, as already has been described.
  • the thereby secured weaving plane WE II is set off within the cycle with respect to its height.
  • the additional thread 60 is arranged in a spreaded position disposed therebelow thus for the formation of the lower shed, also unchanged, the mandrel 16 has retained its position in the lower shed.
  • the remaining warp threads of the fabric are moved sufficiently during shedding with the shown spreading positions 111' and 11", so that relative to the latter it is of no importance, whether the weaving plane is disposed in the position I or position II.
  • the insert 55 oscillates through any conventional drive independently from the rotation of the rotor 47, about a sufficient angular extent, so that by means of the thread passage'59 of the additional threads 60, it reaches a spreaded position from its shown position above the weaving plane WE I, where it forms an upper shed, which spreaded position is spread below the weaving plane WE I substantially at the height of the warp thread 11' or of the member 16.
  • the insert 55 merely performs a swinging movement of about more than 90.
  • the rotary movement of the rotor 47 takes place not only in the same direction, but rather the rotor could also be driven in a cycle once in one rotary direction and then in the opposite rotary direction.
  • the rotor could also be driven in a cycle once in one rotary direction and then in the opposite rotary direction.
  • windings of any other type for instance, windings of a special meander. This can be realized by a relative drive or by suitable couplings in the shown embodiment.
  • the described rotary driven rotor is of importance because it is usable not only during the production of the fastener member rows of slide fasteners, but rather it can be applied for any weaving process, where it is desirable to have a spreading of warp threads for the threading through of weft threads.
  • the rotor will be arranged in accordance with the showing in FIG. 1, with the rotor plane as substantially most possibly parallel to the plane of the spreading position of the warp thread.
  • a warp thread is disposed in the upper shed, while the other warp thread is arranged in the lower shed. After a half rotation of the rotor, the warp threads are arranged opposite to each other.
  • a method of producing a slide fastener tape comprising the steps of moving warp threads back and forth through a weaving plane so as to produce successive warp sheds
  • An apparatus for producing a slide fastener tape including a row of fastener members formed of a continuous profile thread, comprising shed forming means operative to form successive sheds in warp threads passing therethrough,
  • said rotor having an opening constituting a threadingeye for moving a profile strand through a shed forming motion driving rotation of said rotor
  • a weft insertion means for passing weft thread throughsu'ccessive sheds
  • the distance of said opening from said rotary axis of said rotor being at least equal to the total shed height required for the passing through of said weft insertion means.
  • said means including a thread feeding means which is driven synchronously with the rotation of said rotor.
  • said thread feeding means includes an unwinding member rotably mounted on a hollow shaft and adapted to move said other thread during delivery thereof about said profile strand, and
  • said hollow shaft providing a guide through which said profile strand is moved during delivery to the rotary means.
