Definitions

  • This invention relates to a heat treatment method and apparatus for stabilizing the dimensions of a tape-like object consisting of a heat-shrinkable material prior to submitting the object to a dyeing process.
  • the object e.g., a fastener tape or a fastener chain having elements consisting of a formed monofilament secured to a fastener tape, is dimensionally stabilized by applying heat thereto before dyeing in order to shrink the object in advance, and further by stretching the object after the heat-shrinkage step.
  • a tape-like object made of a heat-shrinkable material often requires to be preshrunk by a heat treatment in order to obtain dimensional and structural stability. This is particularly true of a slide fastener tape or of a fastener chain having elements consisting of a formed plastic monofilament secured to a tape, in which the tape or chain requires the removal of residual strain or deformation in a weaving and knitting process, bead forming process and sewing process. Since the tape-like object is subsequently subjected to heat in a dyeing process, it also requires to be heat- shrunk prior to dyeing in order to be provided with dimensional stability.
  • the tape-like object of the type described above is subjected to heat treatment by being wound around a plurality of rollers and heated while fed by the rollers.
  • the relation between the amount of shrinkage and heating time is nonlinear, with the degree of shrinkage being great at the beginning of heating and gradually diminishing with the passage of time. If the rollers are merely driven at the same speed, therefore, the tape-like object will sustain a large tensile force at the initial stage of the heat treatment.
  • the apparatus includes a heating unit having a casing for establishing therein an environment consisting of a high-temperature fluid, and a plurality of first drive rollers provided inside the casing for feeding a tape-like object wound therearound; a feed roller for feeding the tape-like object into said heating unit and control means for rotating said feed roller and said first drive rollers in such a manner that said feed roller rotates faster than each of said first drive rollers and said first drive rollers rotate at a progressively lower speed from a supply end to a discharge end of said heating unit.
  • the final length of the tape-like object following heat treatment is not regulated in any active manner, and local differences in heat shrinkage translate directly into a deformation in overall shape.
  • An object of the invention is to provide a heat treatment method and apparatus to perform a heat treatment in a correct and stable manner, and to cope rapidly with any change in degree of shrinkage.
  • Yet another object of the present invention is to subject a number of tape-like objects to heat treatment at one time in an efficient manner.
  • a further object of the present invention is to provide a heat treatment method and apparatus particularly suited to treatment of a tape-like object made of a polyester material.
  • the tape-like object which has been subjected to sufficient shrinkage by the preceding heat treatment, can be cooled and heat-set while being stretched.
  • the amount of shrinkage required can therefore be controlled in a reliable manner.
  • the method of the invention, inclusive of foregoing cooling step, is particularly advantageous when applied to a polyester-based tape-like object.
  • the apparatus includes a heating unit 1, a supply unit 3 for feeding a tape-like object 2 into the heating unit 1, and a discharge unit 4 for extracting the tape-like object 2 from the heating unit 1.
  • the heating unit 1 has a casing 5 for establishing an atmosphere of high-temperature air therein, and a plurality of rollers 6 around which the tape-like object 2 is wound to be fed thereby.
  • a heater 7 Provided inside the casing 5 is a heater 7. Air drawn into the casing 5 from an air intake 8 thereof is fed into the heater where the air is heated before being fed into a duct 11 by a blower 9.
  • the duct 11 is arranged in such a manner that the tape-like object 2 wound around the rollers 6 is supplied with the heated air in a uniform manner. Air which has heated the tape-like object 2 after being injected toward the rollers through nozzles Na and has accumulated in the casing is charged from discharge ports 10 and 12. Though air is used for heating the tape-like object in the illustrated embodiment, any suitable fluid can be employed in a similar manner.
  • the rollers 6 are divided into first, second, third and fourth groups 13, 14, 15 and 16, respectively.
  • Each roller 6 is provided with a sprocket, which is not shown.
  • the four groups of rollers 13, 14, 15 and 16 are arranged to be actively rotated by respective drive units 17, 18, 19 and 20.
  • the rollers within the group may be rotatively driven at the same speed by a single drive unit.
  • the rollers 6 thus serves as drive rollers.
  • Shrinkage curves exhibited by three different tape-like objects having a heat shrinking property are depicted in Fig. 4. It will be appreciated that while degree of shrinkage differs depending upon the material, the rate of shrinkage is high at the start of heating and diminishes with time for all three of the materials.
  • a drive unit 26 for driving the feed roller 25, and the drive units 17, 18, 19, 20 for the rollers 6 in the corresponding groups 13, 14, 15, 16 are adapted so as to drive the feed roller 25 and the corresponding roller groups at speeds which differ from one another.
  • the drive units 17,18,19, 20 and 26 are electrically connected to a common control apparatus 27, which is adapted to supply each drive unit with a command signal desig- hating the speed at which the drive unit is to rotate the roller or rollers driven thereby.
  • Data giving the proper roller speed calculated in advance from the shrinkage curve of the tape-like object to undergo treatment is fed into the control apparatus 27 through an input medium such as a punched card.
  • the control apparatus 27 produces command signals commensurate with the data and applies the signals to the proper drive units.
  • the control apparatus can be provided with an internal microcomputer programmed to compute roller speed automatically and to apply the resulting command signals to the drive units. With this expedient, therefore, one need only enter data indicative of the measured degree of shrinkage of the tape-like object.
  • the supply unit 3 includes the above-mentioned feed roller 25, a guide roller 31, a pressure roller 32 and a guide roller 34.
  • the tape-like object 2 is passed over the guide roller 31, travels under pressure between the feed roller 25 and pressure roller 32 and then traverses the tension roller 33 and guide roller 34 before being fed into the heating unit 1.
  • the tension roller 33 is mounted on one end of a lever 36 which is pivotal about a support shaft 35, the end of which opposite the tension roller 33 is provided with a weight 37 capable of being displaced relative to the support shaft by an adjustment screw 38. Regulating the position of the weight 37 by the adjustment screw 38 enables the tape-like object 2 to be subjected to a tension preselected in accordance with the material constituting the object.
  • the heat treatment conditions may thus be fixed to uni- formalize shrinkage.
  • the discharge unit 4 includes a cooling device 41 and a discharge section 42.
  • the cooling device has feed rollers 43, 44, the former also serving as a discharge roller, upper guide rollers 45, 46, 47, 48, 49, and lower guide rollers 51, 52.
  • a housing 53 defines a cooling compartment 54 around the tape-like object 2, which travels between the upper and lower guide rollers. Air for cooling the tape-like object 2 is drawn in from an air inlet 55 through nozzles Nb by a suction device, not shown, and exits, after cooling the object, via a discharge port 56.
  • Drive units 57, 58 for driving feed rollers 43, 44, respectively, receive command signals from the control apparatus 27.
  • the drive unit rotates the feed roller 44 at a speed lower than that of the feed roller 25 but slightly higher than that of the feed or discharge roller 43.
  • the tape-like object 2 is thus cooled and heat-set while being elongated by the action of the rollers 43, 44.
  • the feed roller 43 is rotated slower than the rollers 6 in the fourth group 16, with the actual rotational speed depending upon the shrinkage curve of the tape-like object 2.
  • Lengthening the tape-like object in this manner while cooling is in progress stretches the satisfactorily shrunk object to endow it with a prescribed shrinkage factor.
  • the cooling process also heat- sets the object so that the shrinkage factor provided will be retained thereby. This makes it possible to reliably supply a subsequent dyeing process with a tape-like object that meets all the shrinkage requirements demanded of a fastener tape or fastener chain that is to be submitted to dyeing.
  • the discharge section 42 of the discharge unit 4 has a guide rbller 59 and diverting rollers 61, 62, 63, 64, for guiding a plurality of the tape-like objects 2 into respective receptacles.
  • the rollers 6 of the heating unit 1 are divided into a plurality of groups each of which is driven by a single, corresponding drive unit.
  • a drive unit can be provided for each one of the rollers 6 so that each roller can be driven at a rotational speed different from the others. While such an arrangement will raise overall cost owing to the greater number of drive units, it will permit the tape-like object-2 to be fed at a speed which is much closer to that required by the shrinkage curve of the object. It is also permissible in the cooling device 41 to actively rotate the guide rollers 45, 46 at the same speed as the feed roller 43, and the guide rollers 48, 49 at the same speed as the feed roller 44.
  • the advantages of the present invention are numerous. Specifically, since the tape-like object is heated while it is being fed at a rate which conforms to the shrinkage curve thereof, the heat treatment can be performed under a condition in which the overall length of the object internally of the heating unit is substantially free of tension or is constantly tensioned to a prescribed degree. Further, since the rate at which the tape-like object is fed is regulated actively by rollers which are driven rotatively, control of the final amount of shrinkage is performed in reliable fashion and undesirable deformation of the object does not occur even if there are local variations in shrinkage characteristic. The invention also raises processing efficiency by enabling a plurality of tape-like objects to be processed simultaneously.
  • the tape-like object which has been subjected to sufficient shrinkage by the preceding heat treatment, can be cooled and heat-set while being stretched.
  • the amount of shrinkage required can therefore be controlled in a reliable manner.
  • the method of the invention, inclusive of foregoing cooling step, is particularly advantageous when applied to a polyester-based tape-like object.
