FIBER CONTAINERS AND COMBINED RIVER TUBES AND PLASTIC RING TUBES DESCRIPTION OF THE INVENTION • This request is related to the application No. 5 of Series 09 / 063,278, entitled: "REELEX II Winding Coils with Large Payout Hole and Tube for Twistless Payout", filed on April 21, 1998 and assigned thereto empowered as the present invention. The subject matter of this application is incorporated herein as reference. This invention relates to drop tubes for guiding filamentous material through a drop hole extending from the outer winding to the inner winding of a coil of filamentous material winding in a winding of figure 8, and in particular with such drop tubes made of plastic material or corrugated fiber and which have an oval, diamond, elliptical or round configuration, with a larger opening for accommodate CAT 5, CAT 6 and CAT 7 cables that are can freely unroll from the inner spool to the outer spool of the wound material. The invention is also useful for improving the loosening of filamentous material different from CAT 5, CAT 6 and CAT 7, i.e., any filamentous material.

Some of the lowering tubes are made of molded plastic, some are made of molded paper pulp and some are made of corrugated hardboard. Drop tubes that perform the function of guiding filamentary material through drop holes in reel rolls are known in the art. The structure of such drop tubes is represented by the following patents all of which are assigned to the same assignee of the present application, and wherein: 10 (1) United States Patent No. 4,274,607 • entitled "Guide Device for Use in Elongate Filament Dispensing Package and the Like" describes a tubular guide device inserted radially into a drop hole in a roll winder and through a hole in a carton containing the roll winder and including means for securing the guide device to the cardboard. (2) U.S. Patent No. 4,367,853 and entitled "Guide and Support Members for Unwinding Flexible Material from a Wound Package" describes cones specially formed adapted to extend within the interior opening of the drop tube to prevent tangles and slag formation as the filamentary material is unwound from the winder. (3) U.S. Patent No. 4,057,203 25 entitled "Package of Flexible Material with Oval Payout Tube" discloses an oval drop tube that is inserted into the normal diamond-shaped drop hole of the winder roll. • (4) U.S. Patent No. 4,022,399 5 entitled "Screw-in Tube with Breakable Tabs for Coil of Flexible Material with Inner End Payout "describes a drop tube with separate tabs for attaching the wall of the container that holds the roll winder and with the opposite end of the drop tube of the tabs being inserted 10 inside the radial drop hole of the roll winder (5) U.S. Patent No. 3,985,315 entitled "Packag of Flexible Material for Twistless Payout with Wide Funnel Guide" discloses the outer end of the funnel-shaped drop tube 15 Despite the aforementioned advances in The state of the art of lowering tubes, advances and the development of new types of wire rope has generated the need for new types of lowering tubes to allow adequate lowering without entangling wire wound cable from the inner winding to the outer winding and through a radial opening between the inner and outer windings. In particular, the residual inherent turning characteristic of the CAT 5, CAT 6 and CAT 7 cables requires a much larger drop hole and a lowering tube. to prevent entanglement and interference with the lowering of the cable when entangled in a configuration in Figure 8 and with a lowering orifice extending from the inner winding to the outer winding of the roll. In addition, the present invention is related to the application Serial No. 09 / 063,278 as indicated above. The assignee has designated the new winding system as a REELEX II package and the drop tubes according to the present invention are part of the new REELEX II package. According to the REELEX II package, many new products can be used with the authorized and patented REELEX system of the agent. Products that have been considered too rigid, too flexible, too hard, too soft, that are easily damaged, too prone to tangles, too big, or too small for REELEX packaging will work very well in the REELEX II package. For example, simple drivers, and ultra-flexible cable. Fiber optic cables are now all candidates for simple conductors, ultra-flexible cable and fiber optic cables can now be used with the REELEX II package. The new REELEX II package also significantly improves the cold weather lowering performance of many cable constructions. With the use of paper pulp drop tubes or corrugated hard cardboard instead of plastic drop tubes, both the container and the drop tube are recyclable and thus the REELEX II corrugated fibreboard cable package will satisfy the rigorous requirements • waste reduction of workplaces and the 5 regulations of today's "green" European packaging. Alternatively, the plastic tubes of the present invention can be used in a REELEX II package where such use is desired, such as sturdy, rigid wire cables, which tend to damage the paper materials corrugated. • It is therefore a principal object of the present invention to provide a package of wound filamentary material of the type specified herein, a drop tube which is made of corrugated paper product, paper pulp or plastic. It is a main feature of the present invention that the drop tube is formed of corrugated paper as well as the cardboard containing the roll winder. It is an advantage of the present invention that the corrugated paper tube and the corrugated paperboard are recyclable. It is another object of the present invention to provide an enlarged drop tube which engages with an enlarged dropping hole to provide the loosening of rolled flexible material having unusually rigid, flexible, hard, soft, prone to tangles, large or small. • It is another feature of the lowering tube of the present invention that an enlarged lowering tube provides unwinding free of kinking and entanglement of filamentary material from a rolled package. It is another advantage of the lowering tube of the present invention that the flexible rolled material having unusually rigid, flexible, hard characteristics, • soft, prone to tangles, large or small can be unrolled without tangles or kinking. BRIEF DESCRIPTION OF THE DRAWINGS The above objects, features and advantages of the invention will be more apparent from the following description of the preferred embodiments of the invention when taken into consideration with the following drawings, in which: Figure 1 is a perspective view of a lowering tube 20 according to a first embodiment of the invention; Figure 2 is a side cross-sectional view of the lowering tube of Figure 1; Figure 3 is a view of the lowering tube of Figure 1 as viewed from the outlet opening side thereof; Figure 4 is a front view of a second embodiment of a lowering tube according to the invention and made of plastic; Figure 5 is a cross-sectional view of a plurality of drop tubes of Figure 4 shown in a grouped relationship; Figure 6 is a view in sectional view • transverse of the lowering tube of Figure 4; Figure 7 is a front view of a third embodiment of the lowering tube according to the invention; Figure 8 is a side view of the third embodiment of the invention; Figures 9A and 9B are respective front and side views of a fourth embodiment of the invention made of corrugated paper; Figure 10A is a cut away perspective view 20 of a fifth embodiment of the invention in which the drop tube and the container holding the roll winder are each made of corrugated hardboard; and Figure 10B illustrates a plan view of each of the respective sections of the corrugated fibreboard 25 forming the embodiment of Figure 10A.

The drop tubes described herein are essentially made to operate with the drop holes made in accordance with the above teachings set forth in the related patent application Serial No. 063,278 and assigned to the same proxy of the present invention. The drop tube 20 of Figure 1 is preferably made of injected molded plastic or paper pulp and includes a body 22, a coaxial inlet opening 24 and an outlet inlet 25. As illustrated in Figure 1, the opening input 24 and output opening 25 are circular (see Figure 3) as will be explained in detail later. The distance between the inlet opening 24 and the outlet 25 can be varied as desired to accommodate rolls of different diameter sizes. The cord 26 extends around the circumference of the outlet opening 25 for coupling the side panel of a container holding the winder roll as is well known to those skilled in the art of lowering technology. The lowering tube 20 is made of molded plastic injected in accordance with well-known techniques of molding plastic, paper pulp or corrugated paper. The body 22 of the lowering tube 20 is thinned from the diameter of the outlet opening 25 to the diameter of the inlet opening 24 as illustrated in Figure 1.

In the side view of the lowering tube 20 shown in Figure 2, the thickness of the body wall 22 is approximately .04 inches for the plastic tubes and • inch for paper pulp tubes. The distance 5 between the inside of the inlet opening 24 and the outside of the outlet opening 25 is about 3.5 inches. The length of the drop tube 20 can be increased or decreased as necessary to accommodate the width of the winder rolls with which uses the drop tube 20. The cord 26 extends further • beyond the sides 27 of the lowering tube 20 an amount sufficient to provide an appropriate coupling of the cord with the side panel of the container (not shown). Figure 3 is a rear view of the tube of is lowered 20 (ie, as seen from the end of the outlet opening 24 of the drop tube 20) and shows the circular configuration of both the inlet opening 24 and the outlet opening 25 of the drop tube 20. • inner diameter 24A and outer diameter 24B of the outlet opening 24 differ approximately .04 inches for the plastic and inch pulp tubes to provide the stiffness and texture suitable for accommodating the rigid filamentary material. The inner diameter 25A and the outer diameter 25B of the opening of outlet 25 is also shown and preferably there is a difference of 3-3 inches in the respective diameters to provide a thickness of .04 inches for the plastic tubes and k inches for the paper pulp drop tubes of the tube body 22 20. The outlet opening 25 includes a portion of cord 25B that rests against the outer surface of a container panel that houses the unwinding roll (not shown) as is known in FIG. technique . The inlet and outlet openings 24 and 25 are large enough to allow the filamentous material to be wound in a configuration with a radial opening from the outer winding to the inner winding to be extracted from the inside of the winder and through the drop tube 20 without forming slag or tangles. The configuration of the lowering tube 20 according to the invention essentially eliminates the entanglement and slag formation of CAT 5 cables, CAT 6 and CAT 7 and also improves the lowered rolling of all the other filamentous materials wound according to the REELEX I and REELEX II techniques, for example as described in US Patent No. 4,406,419 for REELEX I and this request as well as the application with Serial No. 09 / 063,278 for the REELEX II techniques. For more explanation about the size of the openings to allow lowering without tangles, see application Serial No. 09 / 063,278.

Figures 4-6 illustrate another embodiment of the invention wherein the inlet and outlet openings are oval. In the upper view of the lowering tube 30 including the exit opening 31 and the entry opening 32 both in the shape of a diamond and wherein the dimensions of the two openings are as follows: The width and length of the opening input are 2.49 and 1.77 inches, respectively; the width and length of the diamond-shaped exit opening are 5.06 and 3.66, respectively. Figure 5 illustrates the manner in which the lowering tubes 30 can be grouped. Figure 7 simply illustrates an elliptical landing tube 40 (football) and Figure 9 shows a side view of the drop tube 40. Figures 9A and 9B illustrate a drop tube 50 made of corrugated hard corrugated board. and having a truncated shape as shown in Figure 9B. The flanges 51, 52, 53 and 54 extending from the respective sides of the diamond-shaped outlet opening 55 are bent to form the sides 56 and 57 of the drop tube 50. The cords 58, 59 are formed by bent tabs for coupling the side panel of a container (not shown) to allow the lower tube 50 to remain in position with respect to the dropping hole of the winder roll housed in the container.

The formation of the drop tube using corrugated fibreboard or other paper products provides a significant advantage over the ecological disposal of the drop tube, for example compared to a drop tube formed of plastic. A combined container and a lowering tube according to a fourth embodiment of the invention illustrated in Figure 10A and showing the container 60 for securing a filamentary material winding roll (not shown) and includes a lowering orifice extending from the • inner winder to the outer winder and is formed according to the method described in the aforementioned application with Serial No. 09 / 063,278. A grooved opening 62 is provided in panel 63 and opened to allow the filamentous roll to be removed from the container 60. The filamentary material (not shown) is passed through a drop tube 64 shown in imaginary lines and which is incorporated as part of the container 60 as will be described in detail later. The hilt 65 allows the container 60 to be transported from one place to another. The semicircular cut provides access to the interior of the container 60 after it is assembled as will be described in detail below with respect to the Figure. The container 60 is sized according to the diameter of the winder roll to be contained therein and is It can manufacture in standard sizes to accommodate standard diameters of winder rolls. For example, the container 60 shown in Figure 10A can be 9.5 inches x 13.5 inches to accommodate a roll winder with a diameter of 12 inches. The opening 62 may have a circular, diamond, or oval shape according to the description in the application Serial No. 09 / 063,278. A cross-shaped opening 67 allows the end of the • filamentary material leaving the opening 62 can be inserted to prevent it from moving freely in a random manner and returning inside the container. Figure 1QB shows a plan view of the container 60 as it appears in its disassembled form and consists of four sections, mainly sections 70, 72, 74 and 76. First section 70 includes an end panel 71, a bottom panel 73 and an upper panel 75. The top panel 75 in turn includes a V-shaped cut 77 which is part of a diamond-shaped drop tube that will be described in its entirety below. The handle 78 allows the container 70 to be transported as desired. Grooved orifice 79 allows the end of the filamentous material of the bobbin roll can be inserted, which prevents it from moving freely. The flange 80 on the side of the end panel 71 is a flange with adhesive that connects the panel sections 70 and 76 during the manual process that produces the box.

• The second section 72 comprises a side panel 5 81, a lower panel 82 and an upper panel 83. The upper panel 82 includes a diamond-shaped drop tube opening 84, a handle 85, an opening 86 which is aligned with opening 79 in upper panel 75. Lashes 87 and 88 in upper panel 83 provide means to secure the upper panel 83 with a top panel of • Counterpart in the fourth section 76 that will be described in detail later. The flanges 89 and 90 in the lower panel 82 also serve to secure the lower panel 82 with a lower counterpart panel in the fourth section 76.

The third section 74 comprises an end panel 91, a lower panel 92 and an upper panel 93. The upper panel 93 includes the other half of the drop tube with diamond-shaped and round opening 94 formed together with the V-shaped cut 77 in the upper panel 75 when the different sections of the container are folded during assembly. The fourth section 76 includes a side panel 95, a bottom panel 96 and an upper panel 97. The side panel 95 includes a port 98 which provides access to the roll winder when the container 60 is assembled. The lower panel 96 includes a flange 98 for coupling a counterpart opening in the lower panel 82. The upper panel 97 includes a grooved opening 99, which is aligned with the • lowering tube opening 84 in the upper panel 83 when the container 60 is assembled. Once the box is assembled the grooved handle 100 is aligned with the grips 78 and 85 which provide three larger corrugated thicknesses and an increased force to transport the container 60. The flange 101 engages a counterpart opening in the upper panel 83 when the container 60 is assembled by bending the various sections described above. The procedure for assembling the container 60 is as follows: 15 (1) The drop tube (with round diamond or oval shape) is inserted into the hole of the coil. (2) The coil is then inserted inside the box (after the bottom part has been formed and the coil material is passed through the guide tubes). (3) The flanges 75 and 93 slide under the flange of the tube by bending the flange at A and B. At this point, a round pipe will be held by the round portion of the cut 77/94. A diamond will remain in place and shaped by the pointy area of the cut 77/94. The side flanges 75 and 93 both have fins (X and Y) that engage the Z-groove. When these fins engage with the groove, the two flanges prevent the pipe from falling into the box when the bobbin is fully lowered. . (4) The flange 83 bends over the tube, which helps to hold the tube in place together with the upper flange 97. When the container 60 is assembled as shown in Figure 10A and as described above, with a roll wound from filamentary material included therein, the end of the filamentary material (not shown) is unwound through the drop tube 71, 77 and 84 without tangles or slag formation. The combined vessel and drop tube structure according to the invention provide a single structure for housing and lowering the wound filamentous material. The construction of the container 60 of the corrugated cardboard causes the drop tube and the container to be recycled. In summary, the round paper pulp guide tube has a wall thickness of approximately one inch and can be made in several lengths depending on the size of the coil with a 2-1 / 2 inch inlet opening. as illustrated in Figure 1. The paper pulp diamond-shaped guide tube (with rounded corners) has a wall thickness of about an inch and has the approximate dimensions as the diamond-shaped tube discussed in the FIG. previous description. The paper pulp material has the distinct advantages of being biodegradable and recyclable. It is also the least expensive of the three materials described here and can be purchased near any place where it will be used, which significantly reduces transportation costs. The round plastic guide tube has a wall thickness of approximately .04 inches, is biodegradable and has the advantage that it can be stacked more efficiently than the paper pulp guide. This makes transportation costs lower, in addition to the other advantages mentioned in the previous description. The advantage of the round tube on the diamond-shaped corrugated pipe is that it tends to retain its shape once it is inserted into the drop hole. Usually, it tends to become oval. However, the side flanges 75 and 93 (Figures 10B) form a diamond-shaped opening once they have been placed behind the lip of the guide tube and help retain the diamond shape. The above description serves only to describe the exemplary embodiments of the best mode for making the drop tubes and the combined fiber container and the plastic drop tubes to demonstrate the characteristics and advantages of their construction and operation. The invention is not intended to be limited by this, since those skilled in the art to which the invention is directed will readily perceive the modifications of the modalities described above. In this way, the invention is intended to be limited only by the following claims and the equivalents to which the claimed components thereof are entitled.
