(57) The invention relates to a spool (1) for thin loop metal wire comprising a hollow
cylindrical body (2), at the ends of which there are detachably connected two end
flanges (3) by fasteners (5), so that each end flange (3) is provided with recesses
(6; 6") belonging to the locking elements (6) for locking the position between the
end flange (3) and the fastener (5), located at the edges (3b) of the flange center
hole (3a), and the body (2) is in the vicinity of the body ends (2c; 2c",2c') provided
with apertures (4; 4") belonging to the locking elements (4) for locking the position
between the body (2) and the fastener (5), and each spool fastener (5) has a cylindrical
casing (5b), the bottom edge of which is connected to the bottom (5a) and the top
edge is provided with a brim-like protrusion (5c), On the fastener casing (5b), immediately
underneath the brim-like protrusion (5c) of the fastener, there is arranged a number
of brackets (6; 6') belonging to the locking elements for locking the position between
the flange (3) and the fastener (5) that can be fitted essentially completely in the
recesses (6,6") provided at the edges of the aperture (3a) located in the center of
the end flange. Near the top edge of the fastener casing (5b), there are arranged
spring-like tongue elements (4; 4') belonging to the locking elements of the position
between the spool body (2) and the fastener (5), which spring elements can be fitted
at least partly from inside the hollow body (2) in the spool body apertures (4; 4")
belonging to the locking elements of the position between said hollow body (2) and
fastener (5).
