Abstract

The present invention relates to pearls that allow the embroidery of pearls with high quality to be carried out safely and stably using a continuous form of pearls, which can be achieved with an automatic embroidery of the pearls. The beads consist of a lamellar film formed by stratification of films having different thermal shrinkage index in a predetermined direction. The lamellar film is subjected to a heat treatment and rolled into a cylindrical shape to form a cylinder. Cuts are formed in the cylinder at predetermined intervals to form the continuous perl member

Description

TECHNICAL AREA The present invention is attached to decorative beads or beads which are sewn onto clothing or the like in an embroidery process.

BACKGROUND OF THE INVENTION The present application relates to a useful method and apparatus for embroidering beads already developed in a patent publication (Japanese Patent Application Laid-open No. b-321122). According to the known published technique, by using a continuous member such as a cord or cord containing multiple cylindrical beads connected in the axial direction, embroidery of high quality pearls can be performed in a stable and secure manner. The continuous member of beads that is used in the aforementioned technique can be made in various ways by different types of methods. It is possible to achieve remarkable effects using the pearl embroidery method of the published technique by applying any form of continuous bead member with the embroidery method.

Without e.Tibargo, the applicant intends to innovate the continuous member of beads applicable to the pearl embroidery method and the apparatus described in the aforementioned publication, so that, moreover, the method and apparatus of the known art can be efficiently developed. Therefore, an object of the present invention is to provide the pearls that allow to carry out, in a stable manner, the embroidery of pearls with high quality by means of the use of a continuous form of pearls with which it can be carried out, embroidered Automatic pearls.

DESCRIPTION! OF THE INVENTION in order to achieve the objective, the present invention provides beads which consist of a lamellar film formed by stratified films having different rates of thermal shrinkage in a predetermined direction, the laminated film is subjected to a heat treatment and rolled in a cylindrical shape to form beads or beads. In accordance with a preferred embodiment of the present invention, the beads are made in a continuous member shape containing a plurality of cylindrical pearls divided continuously in the axial direction, to form radial cuts in a cylinder leaving a part of the cylinder ijitacta as connecting section between the successive beads. The invention also provides a method for producing a continuous member of beads, wherein the tape is longitudinally tapered, formed by stratified films having different rates of thermal shrinkage in the lateral direction of the tape, is it treated by heating? It is wound in the lateral direction so that continuous elongated cylinders are formed in the direction 0 length and where cuts are formed in the cylinder at predetermined intervals, leaving a part of the cylinder intact, connecting section between successive beads, so that it forms a continuous member containing a plurality of continuous cylindrical beads in the axial direction. The stratified film is formed, for example, from a lamellar tape formed by superimposed films having different rates of thermal contraction in the lateral direction. When the tape or lamella is heated, 1 tape is wound in the lateral direction due to the difference between the thermal contraction indexes of the films, so that a cylinder is formed from cmt. from this, cutting is formed in the cylinder at predetermined intervals to form a cylindrical member of cylindrical pearls. Even if the rolled beads are reheated later, the beads do not unroll, therefore, the cylindrical shape remains stable.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective view of the lamellar tape to form the beads according to the present invention. Fig. 2 is a perspective view of a cylinder formed by heating the ribbon of Fig. 1. Fig. 3 is a perspective view of a continuous member of elaborate beads forming cuts in the cylinder of Fig. 2.

PREFERRED METHOD FOR CARRYING OUT THE INVENTION Figure 1 is a perspective view of a lamellar tape to form the beads of the present invention. This lamellar tape is formed by the stratification of a first film 2 and a second film 3 made of, for example polyester, and having different rates of thermal contraction in the lateral direction (arrow A) of the tape. The thermal film of the first film 2 is adjusted to be larger than that of the second film 3. Otherwise, the rate of thermal expansion of the second film 3 is adjusted to be greater than that of the first film 2. In any case, it is desirable that the contraction index of the films in the longitudinal direction (arrow B) of the tape be the same, by heating the lamellar tape using an electric heater or other suitable heat treatment medium. , The tape is wound in the lateral direction, as shown in figure 2, due to the difference between the thermal contraction index of films 2 and 3, so that a continuous shape of an elongated cylinder 1.. When the shape of the cylinder is stabilized, the heat treatment is stopped to allow hardening of the cylinder, cuts 4 are then formed, using a cutter (: or shown) at predetermined intervals in the cylinder Ib with a connecting section. which is left intact in successive re pearls in a part of the cylinder in radial direction of each section of cut. In this way, u is formed: continuous member of pearls consisting of multiple spindles 6 connected in axial direction. The bead member is placed in a convention apparatus in which each bead is automatically separated and a cloth sewn. When < p the embroidery of the pearl is performed, the lamellar tape that of figure 1 is wrapped in a first roll form. The roll of the tape is unwrapped and the tape is passed through a heating means to form the cylinder of FIG. 2. Thereafter, the cylinder is successively passed through a cutting means to form the continuous member of the beads. Figure 3. The continuous member of the pearls is then placed successively in an apparatus for embroidering pearls. In this way, the embroidery process of a series of pearls can be automated. Note that although the lamellar tape of the modality mentioned in the above has a two-layer structure, it is possible to use a lamellar structure having three or more layers in order to improve the ornamental effect by means of the thickening of the beads or the application of different colors to the layers. It is also possible to use various types of films such as the type of films with thermal expansion, thermal shrink type films or a combination of both types of films in the films of the lamellar tape to form the cylinder by winding the lamellar tape by heat treatment. it was mentioned in the above, in accordance with the present invention, it is possible to easily form cylindrical beads using a simple system and to make efficient an automated bead embroidery process.Also, if after being formed heat is applied again to the beads, The thermostrain works to roll up the cylinder more instead of unrolling it and opening the cylindrical shape, therefore, the cylindrical shape remains stable.

INDUSTRIAL APPLICABILITY In the industrial field of pearl embroidery technology, pearls can be easily formed using a simple system, and the embroidery process can be automated efficiently, as well as the shape of the pearl can be kept stable, which makes possible the improvement of the quality in the products of trimmings.
