Abstract

A coiling system for coiling and uncoiling of the elongated flexible element. The elongated flexible element is preformed and coiled onto a core, which is detachable for the purpose of uncoiling the elongated flexible element by its inner end. A coiling system which comprises a coil component functioning as an end wall so arranged as to interact with a detachable core with an elongated flexible element coiled thereonto.

Claims

1. An apparatus for coiling and uncoiling an elongated flexible element thereon, said flexible element having an outward and an inner end, said apparatus comprising:

at least one end wall having a centralized circular opening therein and a first and a second group of openings radially disposed from said central opening;

a first plurality of removable rod members disposed about said centralized opening wherein each respective rod is attached to said at least one end wall at each opening in said first group of openings, said rod members equidistantly spaced from each other, each of said rod members collectively forming a structurally open, centralized core for coiling said flexible element therearound, said core coextensive with said circular opening of said at least one end wall, said rod members retained in said at least one wall after said core is formed and when said flexible element is to be uncoiled; and

a second plurality of removable rod members disposed about said centralized opening and wherein each respective rod of said second plurality is attached to said at least one end wall at each opening of said second group of openings, said second plurality of removable rod members attached to said end wall after said coil is formed, said second rod members for retaining and holding an outer edge of said coil.

2. The apparatus as claimed in claim 1, further including a second end wall having a central opening, each of said end walls attachable to one another through connection with the first and second plurality of rod members.

3. The arrangement as claimed in claim 2, wherein said first and second plurality of rods are adjustable movable in radially oriented mounting slots formed in exact locations in each of said end walls.

4. The arrangement as claimed in claim 2, wherein said two end walls are retained at a lateral distance from one another by the rod-shaped members, wherein at least one end of the rods includes a fastening means thereon for securing said end to an end wall.

5. The arrangement as claimed in claim 4, wherein at least one end of the rod-shaped members is threaded to accept a screwed-on fastener.

6. The arrangement as claimed in claim 1, wherein said second plurality of removable rod members comprise a connection which extends externally along a coiled elongated flexible element to retain the coil during uncoiling by its inner end.

7. The arrangement as claimed in claim 1, wherein an end wall is divided by a slot, said slot extending between said central opening and an outer edge of said end wall, the slot being covered with a bridging element.

8. An arrangement for coiling and uncoiling an elongated flexible element thereon, said flexible element having an outward and an inner end, said arrangement comprising:

at least one end wall having a centralized circular opening therein and a first and a second group of openings radially disposed from said central opening;

a first plurality of removable rod members disposed about said centralized opening wherein each respective rod is attached to said at least one end wall at each opening in said first group of openings, said rod members equidistantly spaced from each other, each of said rod members collectively forming a structurally open, centralized core for coiling said flexible element therearound, said core coextensive with said circular opening of said at least one end wall, said rod members retained in said at least one wall after said core is formed and when said flexible element is to be uncoiled;

a second plurality of removable rod members disposed about said centralized opening and wherein each respective rod of said second plurality is attached to said at least one end wall at each opening of said second group of openings, said second plurality of removable rod members attached to said end wall after said coil is formed, said second rod members for retaining and holding an outer edge of said coil; and

a coiling arrangement rotatable about said core, said coiling arrangement for feeding said flexible element to said core for coiling thereabout, said coiling arrangement displaced radially outwards from said core and extending across a winding direction of said flexible element, said winding direction parallel to a direction of said first plurality of rods.

9. The system as claimed in claim 8, wherein said coiling arrangement is rotatable about the core such that said flexible element is extended axially in relation to the core before being fed for tangential delivery to the core.
