DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a method of manufacturing a coil of a continuous flexible object, comprising cable, line, wire, wire cable, rope, cord, ribbon, hosing, chain and the like, and enveloping the coil to form a parcel for delivery to a user of the object, said object being coiled onto an axially open, cylindrical sleeve to produce said coil. The invention also relates to a new system for handling a continuous flexible object, comprising cable, line, wire, wire cable, rope, cord, ribbon, hosing, chain and the like, said handling procedure starting with manufacturing a coil and enveloping the coil to form a parcel for delivery to a user, which object is coiled onto an axially open, cylindrical sleeve to produce said coil. The invention also relates to a tool for use with this method and in this system, as well as parcels produced by the method.
The system generally used hitherto for handling live cable and line, for instance, such as bare line for overhead power transmission lines, has a number of drawbacks. With the known system drums made of wood material, usually planks, are used which have a core and two end pieces which are rigidly secured to each other and the core by means of nail and/or screw joints. The end pieces are provided with small central holes, the edges of which usually being formed by the wood material of the end pieces. The end pieces determine the outer dimensions of the cable and line drums and thus the space required for storing empty cable and line drums. Considerable transport and store spaces are therefore need for transporting and storing them before coiling is performed. A drum of the type described is placed in a coiling machine in order to coil a cable or line onto the core so that a coil of cable or line is produced having a diameter slightly less than the diameter of the end pieces. The drum of cable or line is then transferred from the coiling machine to an adjacent station where it is wrapped to protect the coil from impacts, in that boards are nailed between the end pieces to enclose the coil, or the coil being enclosed by a casing of corrugated cardboard material. The wrapped cable and line drums are then stored in an adjacent store for subsequent delivery, or are transported directly to the user. The cable or line installation must be prepared so that the cable or line drums are delivered at the desired places long before the actual installation takes place, usually about two months. During this time the drums are subjected to moisture and rain and even for direct contact with water on the ground so that there is a favourable environment for decay. When the cable or line is to be installed a drum is placed in a special uncoiling trestle at the start of the installation distance, while an empty drum is placed in a coiling trestle at the end of the installation distance. The old cable or line, or a special traction wire, is wound onto this empty drum.
In the coiling machine, and in the uncoiling and coiling trestles, journalling means are brought into engagement with the holes in the end pieces and these holes are consequently subjected to considerable strain resulting in the wooden material splintering. The risk of this increases greatly if the end pieces have been attacked by decay around the edges of the holes. The center of the hole will be displaced from the optimum axis of rotation, resulting in the drum and the coil becoming off-centered so that rotation of the drum becomes unbalanced. In the coiling machine this creates problems in coiling the cable or line in tight, uniform turns and may result in damage to the cable or line so that the entire coil must be rejected as well as the drum. The problem can be reduced by reducing the speed of rotation but this gives an undesired decrease in capacity. Due to the extremely rough treatment to which the drums are subjected, particularly during loading and unloading, the end pieces may be displaced laterally from each other so that the drum becomes deformed. This deformation may be difficult to detect before coili
