Description of the invention (1 Cross-reference to related patent application chapters This application claims that the US provisional application number 60/136 was filed on May 28, 1999, Rights of 536 "Scope of the Invention The present invention describes the use of general forming bobbins for continuous fiber forming operations, and forming packages and fiber masses. BACKGROUND OF THE INVENTION In a typical glass fiber forming operation, glass fibers are extracted from a fiber forming device. Gathered into one or several strands and continuously wound around a detachable sleeve or "formed bobbin" which is positioned on a chuck of a winding device. The collection of fibers on the formed bobbin is called a "fiber block". The composition of the fiber mass on the bobbin is called "shaped package." Once the desired amount of fiber (typically a certain weight) has been wound on the bobbin surface, the shaped bobbin is removed from the chuck for further processing. Traditional The forming bobbin is cylindrical and is typically formed of reinforced paper, and the methods and equipment for forming fibers and forming packaging are well known to those skilled in the art. Can be wound on a given shaped bobbin will vary according to several factors including, but not limited to, the diameter of glass fiber, the number of strand fibers, the number of strands twisted, the number of strands, the degree, the chuck Quality and winding mode 'and the future processing steps to which the glass will be subjected. For example, in a typical textile glass forming operation, the' winding mode must be designed so that continuous strands can be released from the outside of a package on a turret (generally referred to as " "Relax"). Generally, this requires that the glass strands are wound on the surface of the forming bobbin, so that the glass strands comply with the Chinese National Standard (CNS) A4 specification (210 297 issued)

Description of the invention (2) Around each successive layer, the system usually leads to a different aspect from the previous layer. In addition, it is advantageous that the distribution glass may not change beyond the length of the forming tube, in order to maximize the size and weight of the forming package. In order to achieve the required relaxation performance and the maximum usage of the forming bobbin, the strand is laid on the forming bobbin in a staggered mode via a spiral tube. When the chuck of the winding machine reciprocates. A shaped package is formed in this form, typically including a fibrous mass that has—usually a round stomach region having a generally constant thickness, and an end or shoulder region extending generally from the central region outwards and having a thickness that varies from the central region downwards. The tip is towards one end of the fiber mass. The length of the central area of the fiber mass is roughly equivalent to the length of the stroke of the reciprocating chuck, but the shoulder area is roughly equivalent to about half the length of the spiral tube. For more information on the effects of these parameters in forming packaging, see K. Loewenstein Continuous Glass Fiber Manufacturing Technology (3rd edition, 1993), pages 180-186, which can be referenced based on this document. When continuous fibers are established in the forming bobbin, the effective diameter of the central portion of the forming package is increased by each continuous fiber layer laid. This results in a tapered shoulder on the fiber block and a slope along the outer surface of the shoulder. If the slope becomes inclined along the shoulder surface of the fiber block and / or the strand forming tension is too large, the shoulder becomes unstable due to the waves of the glass strand falling on the inclined surface of the shoulder. The wave pattern of such strands (also known as "de-wefting or 'knotting') is highly undesirable when it becomes loose, and the glass fibers under abrasion reduce the overall product quality. To avoid wefting, the amount of glass used to form the textile forming package and the shape outside the forming package are typically carefully controlled. It will be recognized by the professionals as the maximum allowable weight of the formed package, in other words, the weight exceeds -5- This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) --- ί--I Ί II- --- Equipped --- 、,.

Description of the invention (3) After the above situation, the wefting of the slanted shoulder of the fiber block becomes a problem, and it will be based on several factors including the diameter of the bottom inflammation head, the stroke length, the length of the shoulder, and the strand forming tension. For example, the maximum allowable weight of a textile forming package includes G-75 fiber formed in a chuck with a 12 inch (about 30. 48 cm) bottom using a 9 inch (about 22. 86 cm) stroke diameter and a 1.5 inch (Approximately 3_81 cm) Shoulder length 'and a strand tension of approximately 300 grams are approximately 10 kg (approximately 22 pounds). Such a weight limitation prohibits the production of larger shaped packages' which will provide increased output and reduced labor costs. [0010] Accordingly, a method and apparatus are needed which will allow large shaped packages to be formed on shaped bobbins. U.S. Patent No. 5,222,676 describes a method of forming a yarn package (fine yarn) with a large number of glass fibers wound on it and a fixed yarn withdrawing tension. The wound yarn is wound on a bobbin at a fixed transverse length to reach A defined diameter D 'and then the transverse length is reduced so that the length of the yarn laid on it is shortened (line 1, lines 45-55). U.S. Patent Nos. 4,063,688 and 4,055,311 describe that the yarn bundle has an end region having a reduced diameter and a center region of a comparative yarn bundle to accommodate yarn accumulation in the end region. When the yarn is wound around the yarn bundle using a reciprocating transverse device, the end area of the yarn bundle is intended to stack more yarns than the center area of the yarn bundle due to the direction reversal of the end area in the lateral direction. By reducing the diameter of the yarn bundle in the end region, stacking can be adapted to result in improved uniformity of the yarn bundle. U.S. Patents 5,853,133 and 4,371,122 methods and devices for producing fiber packages have a square end.

U.S. Patent No. 4,371,122 describes a method and device for wrapping strand material into a package with a cam transverse mechanism, whose speed can be continuously increased relative to the mandrel to eliminate or counteract the reduction of the spiral angle, in which the strand system is configured In the resulting packaging. The reduction of the spiral angle limits the winding speed that can be produced by the box-end packaging and prevents stable packaging production at high speeds (column 2, lines 3-7). However, there is still a need for a method and apparatus that allows the formation of large forming devices, particularly large textile forming packages, which can reduce or eliminate the phenomenon of weft removal at the shoulder of the fiber block and can be supplemented without substantially changing existing production equipment.

Description of the invention (16) Under the appropriate circumstances The forming bobbin 34, 440, 540 weighs less than about 5 tellurium (about 27 kg), more preferably less than about 2 pieces (about 0 '91 kg), and most preferably less than about 1 pound ( (Approximately 0.45 kg). Lighter shaped bobbins are more suitable for simple operation; however, if the shaped bobbins of the present invention are used in connection with an automated or mechanized processing system, the shaped bobbins are heavier. Β The formation of the shaped bobbins of the present invention will be discussed in general As mentioned above, the term forming package means that a forming bobbin has a proper amount of continuous fibers entangled therebetween, and the term "fiber block" means a combination of fiber windings. The fiber mass can be separated from the shaped package 'by removing the shaped bobbin to form a self-supporting structure. The following discussion is directed to a structure in which a forming bobbin has a central region and a first end region of the forming bobbin, but it must recognize the advantage that the discussion also applies to a forming bobbin, which further includes a second end region such as It was discussed earlier and is shown in Figure 3. Referring now to FIG. 4, the wall surface 466 of the first end region 454 of the forming bobbin 44o has an outer surface 468 which is inclined in a generally outward direction, from the inner edge 47o of the first end region 454 toward the first The outer edge 472 of one end area 4 54. The outer surface 468 is inclined, and such an angle α is formed from the outer surface 468 of the wall · face 66 of the first end region 454 to one of the longitudinal central axes 490 of the forming bobbin 440, which is shown in the figure in the present invention. In the example, the surface 牦 4 is parallel to the central area 45 of the forming bobbin 440.

Description of the invention (17) It is about 1 degree to 90 degrees, The better range is derived from about 5 degrees to about 60 degrees' and the better range is derived from 10 degrees to about 45 degrees. Continuing to refer to FIG. 4, the wall surface 466 of the first end region 454 of the forming bobbin 440 < structure 'reduces the slope of the outer surface 414 of the shoulder region 41o of the fiber block 412 formed in the forming bobbin 44' is compared. A fiber block is wound around the outer edge 416 of a conventional shaped bobbin 412 through the raised fiber block 412, as will be discussed later in more detail. By reducing the slope surface 414 'of the shoulder area 4? 0, the shoulder area 4 1 0 of the fiber block 412 · will be more stable and the fibers tend to have a smaller fiber weft. This sequence will also reduce the damage to the strands and breakage of the twister's because of the improved packaging wire drawing method at the collector end. Furthermore, the shaped bobbin 440 of the present invention allows larger shaped bobbins to be larger in size than conventional bobbin manufacturing, which can substantially reduce manufacturing costs through increased production because the potential for weft removal has been reduced or eliminated. Additionally, because The structure of the shoulder area 41 °, when it is wound around the forming bobbin 440, the yarn speed will be more consistent, resulting in more consistent forming tension and fiber diameter.

Incline the wall surface 466 to reduce the height of the outer edge 416 »Although it is not limited to the present invention, in a specific embodiment, for example, the first end region 454 of the forming bobbin 440 is a 454 structure to lift the fiber block 412 shoulder region 41 0 outer edge 416—distance 422 is higher than the inner surface 424 of the fiber block 412, which is equal to approximately the shoulder area 420 of the fiber block 412. Thickness 426—half '. In other words, the outer edge 416 is approximately equidistant from the outer surface of the fiber block 412. Between inner surfaces 424. For example, it is not limited to the present invention, 'as formed in the shoulder 254 of the fiber block 248 of the conventional forming bobbin 240, the width 228 of the fiber block 248 is shown in FIG. 2 3 inches (7.62 cm) and the thickness 252 of the central region 250 of the fiber block 248 is 1 inch (2_54 cm), the angle 0 'will be approximately 1616 degrees and the angle 外部 of the outer surface 258 of the shoulder area 254 will be approximately 18.4 degrees. In the forming bobbin 440 of the present invention as shown in FIG. 4, the outer edge 416 of the shoulder area 410 of the fiber block 412 is lifted by about 0.5 pairs (about 1.27 cm) through the inclined first end area wall surface 466. This produces an angle of about 170-5 degrees which must reduce the angle of the outer surface 414 of the shoulder area 410 of the fiber mass 412/5 to about 9.5 degrees. This reduces the slope of the outer surface 4 1 4 from about 18: 4 degrees to about 9.5 degrees, reducing the possibility of the fiber strands sliding along the surface 4 1 4 and allowing the production of larger size packages. It must admit that the advantage is that the angle α needs to increase the desired distance of the outer edge 416, which is related to the thickness 426 of the central region 420 of the fiber block 412. According to the -21-this paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 467865 A7 B7 V.

In other words, the inner edge 47. It meets the surface 414 of the shoulder area and the fiber surface 418, in other words, the edge 432. More specifically, referring to FIG. 4 and the example discussed earlier, if the inner edge 470 is aligned perpendicular to the side 432 ', an angle of about 9.5 degrees will raise the edge 416 by about 0.5 inches without changing the entire length of the fiber mass 412 . If the inner edge 47o is located between the edge 432 of the fiber block 412 and the outer edge 416, an angle of about 18.4 degrees ^ will raise the distance required for the edge 416 by 0.5 leaves. Ordered by the Intellectual Property Bureau of the Ministry of Economic Affairs for consumer cooperation Du printed In the embodiment of the present invention shown in Figures 3-5, the end region of the forming bobbin provides a tapered strand support surface with a generally fixed slope. However, it must thank the end region strands for supporting the irregular surface shape. For example and without limiting the present invention, referring to 囷 6, the forming package 644 includes a forming bobbin 640 and a fiber block 612 »the forming bobbin 64o includes a central region 65o and the first end region 654 extends from the first end region 65.
