Knock down spool

A knock down spool comprising:

• a substantially cylindrical central member comprising a cellular plastic and including at least two sections releasably connected with each other in a substantially axially extending plane;
• radially outwardly directed lugs extending along portions of the periphery of said central member and forming gaps between said lugs;
• a pair of grooves provided in said central member, one groove at each opposite end portion of said central member, said grooves providing axially and radially oriented surface portions, said grooves extending in the direction of the ends of said central member restricted by said outwardly directed lugs;
• a pair of radially projecting end flanges releasably inserted each onto one end portion of said central member for holding said at least two sections of said central member in a connected position;
• radially inwardly directed lugs provided on said end flanges, said inwardly directed lugs being insertable into said grooves through the gaps between the radially outwardly directed lugs of said central member and being introduceable behind said radially outwardly directed lugs by rotating the end flanges in relation to said central member;
• a plurality of deformable locking means formed in the bottoms of said grooves within the areas of the radially outwardly directed lugs, each of said deformable locking means cooperating with corresponding locking means formed at the radially, inwardly directed lugs of the end flanges for providing a releasable locking of the end flanges in a correct rotational position in which the lugs of the end flanges are positioned behind the lugs of said central member.
