METHOD FOR PRODUCING A PACKAGE

Abstract: A method for producing a package for an in advance to a ring (7) reeled to a predetermined length cut wire or tube or the like, especially an electrical line (8). The ring (7) is introduced between two perpendicularly to the centre axis directed along at least one ridge connected substantially square panels of rigid material, e.g. cardboard or the like. A substantially tubular at least in the axial direction rigid means (10) is after said introducing moved through both panels and the centre opening of the ring (7) and is thereafter locked in the introduced position in relation to as well the ring (7) as the panels. The package can be used as a reel by removing a protective shell of the package. As an alternative said rigid means can be removed, whereby the line or the like is detached from the centre of the package.

Description: The present invention relates to a method for pro¬ ducing a package for an in advance to a ring reeled to a predetermined length cut wire or tube or the like, especi¬ ally an electrical line, in which the ring is introduced between two perpendicularly to the centre axis directed along at least one ridge connected substantially square panels of rigid material, e.g. cardboard or the like. Electrical lines with slender dimensions are often distributed in the form of rings with a predetermined number of windings without reel. The reason for this is that great demands are made upon the strengths of the reel so that it can be gripped in a modern reel machine, which in turn leads to that the costs for the reels become too high in view of the fact that they normally are thrown away after the line is unreeled. Further, it takes less time to reel in a reeling machine if the reel has not the need to be exchanged after every reeling process. Moreover, prefabricated empty reels are bulky and, therefore, take up a great space of a reeling machine. Such line rings are often packed simply in plastic bags. A plastic bag is a simple and cheap package which, however, is not adapted for keeping the line ring in order during use on a place of work. Accordingly, such line rings also have been packed in cartons, in which a hole is made to detach the line from the centre of the ring. Hereby the line is turned, which is not to be tolerated at certain types of lines. To prevent that at unreeling the line is turned, it is accordingly necessary to unreel the line in the tangen- tial direction from the outer circumference of the ring. To accomplish this it is necessary that the line ring is arranged on a reel with flanges which keep the line ring in order during unreeling. It is an object of the present invention to provide a simple and cheap reel for an in advance to a ring reeled electrical line or other cord formed goods. This object will be achieved according to this in¬ vention by a package in which a substantially tubular at least in the axial direction rigid means 10 is after said_ introducing moved through both panels and the centre ope ing of the ring 7 and is thereafter locked in the intro¬ duced position in relation to as well the ring 7 as the panels. Other objects of the invention will be apparent from the following detailed description of the drawings: Fig. 1 is a perspective view of a stack of sheet formed blanks for use at the manufacturing of a reel according to the method of the invention. Fig. 2 is a perspective view of a blank accordin to Fig. 1, said blank being provided with fold lines, pe foration lines and cuts. Fig. 3 is a perspective view of the blank of Figs 1 and 2 showing the folding to a carton. Fig. 4 is a perspective view of a finished carto and a ring made of a predetermined number of windings of electrical line etc., said carbon being adapted to recei said ring. Fig. 5 is a perspective view shewing the closed carton in which a line ring is enclosed and a non-mounted hub means. Fig. 6 is a perspective view showing the finished carton with the mounted hub means. Fig. 7 is a perspective view showing the line rin on a reel taken away from the carton. Fig. 8 is a sectional view through the line ring and the reel of Fig. 7. Fig. 9 is a schematical view showing the two step at using the carton to detach the line from the centre o the carton. Fig. 1 shows a number of on each other stacked sheets 1 of rigid material, e.g. cardboard or the like. In a first step a blank is produced according to the pre¬ sent invention to a carton according to the appearance o Fig. 2. The carton blank showed in Fig. 2, which blank i not an object of the invention, presents fold lines 2, pe foration lines 3, cuts 4 and recesses 5, which all make possible to provide a carton of the appearance of Figs. 4 3 and 5. Fig. 3 shows the initial stage of the folding of the carton. In Fig. 4 the upwardly open but else already folded carton 6 is shown. Said carton is now ready to receive an in advance to a ring with a predetermined number of wind¬ ings reeled electrical line 8 etc. Radially extending . cuts 4 form substantially triangular flaps 9 which are extended inwardly toward the centre of respektive carton side from the level of the inner circumference ridge of the ring 7, which is to be introduced in the carton 6. After the ring 7 is introduced in the carton 6 the flaps 9 are folded into the centre opening of the ring 7 from the outside of the respective carton side. Thereby, the flaps 9 will extend substantially along the centre axis of the line ring. in the opening formed by the flaps 9 folded inward¬ ly from both sides is introduced in the preferred embodi¬ ment a substantially tubular expandable at least in the axial direction rigid hub means 10 which is locked in the introduced position in relation to as well the ring 7 as the carton sides by expanding the hub means. At this mo¬ ment, the inwardly folded flaps 9 will be clamped between the outer side of the tubular means 10 and the inner most windings of the ring 7. To lock the hub means 10 evenly against the respective carton side said side is provided with flanges 11 at both ends, as is best seen in Fig. 8. The package shown in Fig. 6 can easily be stacked and, hence, it is well adapted for long transports. When such a package arrives to a consumer he will simply break up the package along the perforation lines 3, obtaining both parts shown in Fig. 7. In this case, the right part. consists only of a protective shell for the left part which comprises the line ring 7 mounted on a reel with flanges 9, whereby unreeling of the line 8 from said reel is accomplished in the tangential direction. As an alternative the package can be used as shown in Fig. 9. In this case the hub means is removed by means of a pair of nippers of the like, whereafter the line can be detached from the centre of the carton. Of course, both flanges of the reel do not need be provided as shown in the drawings starting with the ca ton blank shown in Fig. 2, but can be provided by means o two separate substantially square panels of rigid materia between which the ring is introduced. These both panels must be provided with the flaps 9 in the same way as at t carton blank shown. It is also possible to instead of the flaps provi the panels or as an alternative the carton blank with ope ings of a diameter substantially corresponding to the inn diameter of the ring 7. Of course, the hub means 10 does not need to be expandable, but can present a' somewhat greater outer diameter than the inner diameter of the rin 7 and the diameter of said openings . When said hub means is introduced it will be locked by friction against as we the innermost windings of the ring 7 as the inner ridge o the openings in the panels. The above disclosure is for illustrative purposes only, and not for purposes of limitation of the scope of the invention.
