DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a tool for mounting to a parcel to form a rotatable unit, said parcel containing a coil of a continuous, flexible object comprising cable, line, wire, wire cable, rope, cord, ribbon, hosing, chain or the like, an axially open cylindrical sleeve, around which the object is coiled, and two protective rings located at the sides of the coil, said tool comprising two identical wheel-shaped side supports consisting of one larger and one smaller circle segment, said circle segments having dividing edges facing each other, the circle segments including cooperating coupling means and cooperating locking means arranged at the dividing edges in order in operative position to fix the circle segments to each other in a common plane, whereby at least the locking means being arranged to be brought out of their operative positions to permit movement of the smaller circle segment from the larger circle segment.
SE-9101042-1 (corresponding to U.S. application Ser. No. 07/930,660, atty. ref. 268-33) the disclosure of which is incorporated by reference herein, describes a new system for handling cable and line, for instance, said handling starting with the manufacture of a coil of cable or line and enveloping the coil to form a parcel for delivery to a user. The coil is obtained by the cable or line being coiled onto an axially open, cylindrical sleeve. Before coiling is performed, the sleeve is provided with two flat, outer protective rings having concentric support surfaces cooperating with opposing internal or external surfaces of the sleeve, depending on the type of protective rings used. The sleeve is secured by a tool having two parallel side supports with concentric centering elements facing each other so that the sleeve is clamped between the side supports and is centered by their centering elements, a rotatable unit thus being formed. The cable or line is then attached to this unit which is caused to rotate in a coiling machine so that the cable or line is formed to a coil. The finished coil is surrounded by a protective casing, after which strong bands are passed through the sleeve, enclosing the sleeve and the protective rings, and tightened to form said parcel. The side supports are removed from the finished parcel to be used in the manufacture of further coils. The finished parcel is delivered in this state to a work place where a second tool is mounted onto the parcel to prepare for unwinding the cable or line. The second tool also has two parallel side supports with concentric centering elements facing each other. By clamping the parcel between the side supports and centering it by means of the centering elements, a second rotatable unit is formed which is then journalled for free rotation about a horizontal or vertical axis of rotation in a special uncoiling device. When the bands have been cut and the protective casing removed, the cable or line is exposed ready for uncoiling. According to one embodiment the second tool is provided with a connecting means consisting of a hollow shaft and a hollow locking device. The parcel is clamped between the side supports by means of this connecting means whose shaft extends through the sleeve and is in locking engagement with the locking device. When said second tool is to be assembled out in the field one or more special hoisting means must be used, particularly if the coil has relatively large diameter and is so heavy that it cannot be manipulated manually.
The object of the present invention is to provide a tool intended for field use, which will eliminate the need for access to a special hoisting means to assemble the tool on a parcel having a coil of cable or line or other continuous object that is easily bent into a coil.
The invention is substantially characterized in that the side supports on one side are provided with concentric centering elements arranged to receive and center said sleeve, said side supports being designed for displacement towards each other to clamp the centered sleeve between them thereby forming said rotatabl
