text: the preferred form of the invention is shown in fig1 whereby a knockdown cable reel consists of a pair of segmented flanges which slidably engage drum heads positioned within the cylindrical drum . the flange segments are light in weight and comprise a plurality of ribs for structural integrity . each segment has an upper large main body portion and a lower blade portion for insertion into a drum head socket . a stabilizing band or ring is placed around the flange periphery upon assembly to stabilize and hold the flange segments in position and to increase the load bearing ability of the reel . the flange ring may be formed from metal or other suitable materials and rests with the flange ring grooves . for a more complete understanding of the invention and its operation , turning now to the drawings , knockdown reel 10 as shown in fig1 comprises a drum 11 which may be formed from an extruded polymeric material , rolled steel or aluminum sheeting which has been welded and may have a diameter of approximately twenty - four inches and a length of approximately thirty - three inches . as would be understood , other diameters and sizes can be manufactured , depending on the particular cable size and length to be wound and packaged or stored on reel 10 . drum heads 12 , 12 &# 39 ; are inserted into each end of drum 11 as perhaps more clearly shown in fig4 . drum head 12 &# 39 ; as seen in fig5 has a diameter of approximately twenty - four inches and is configured as shown in fig4 to slip partially within the end of drum 11 . drum heads 12 , 12 &# 39 ; may be formed from a suitable metal or a polymeric material of substantial strength such as a suitable nylon , polycarbonate or other material . as further seen in fig5 drum head 12 &# 39 ; includes a plurality of ten sockets 13 as will be explained in more detail below . also , drum head 12 &# 39 ; includes a pair of drive apertures 14 which can be used for tensioning wire as it is rolled from reel 10 , for example with an axle placed through central drum opening 23 . in fig6 a cross - sectional view along lines 6 -- 6 of fig5 is shown to illustrate the cross - sectional configuration of drum head 12 &# 39 ;. as seen in fig1 reel 10 includes a pair of flanges 15 , 15 &# 39 ; attached at each end of drum 11 . flange 15 &# 39 ; as shown in fig1 comprises a plurality of ten flange segments 16 which are formed from a polymeric material such as polycarbonate / pbt as known in the industry or from other suitable materials . polycarbonate has been selected based on its structural integrity , durability and relatively low weight . as would be understood other suitable metals or polymeric materials could likewise be used . flange segment 16 comprises an upper body 17 as shown in fig2 and a relatively small lower blade 18 . ribs 19 form main body 17 and lower blade 18 of flange segment 16 to reduce the weight while maintaining structural strength . end ribs 19 &# 39 ; may have a means to attach one to another , such as a tongue and groove or other configuration . in fig3 the top of segment 16 is shown which includes a groove 20 for receiving flange ring 21 as seen in fig1 . flange rings 21 , 21 &# 39 ; may from thin , flat steel straping or may be formed from nylon or the like . flange ring 21 &# 39 ; as shown in fig1 includes a connector 22 which has been pressed onto ring 21 &# 39 ; to hold ring 21 &# 39 ; together . ring 21 &# 39 ; as shown in fig1 is urged over flange 15 &# 39 ; to maintain segments 16 securely therein whereby reel 10 can be rolled , moved , unwound , transported and the like without concern for maintaining the integrity and stability of segmented reel flanges 15 , 15 &# 39 ;. in fig7 another embodiment is seen in which knockdown reel 30 is shown in partially exploded form . flanges 31 , 31 &# 39 ; are formed from a plurality of segments 32 which may be constructed as earlier discussed regarding segments 16 . segments 32 being somewhat triangular shaped are positioned within sockets 33 which are attached to drum slats 34 . drum slats 34 are slidably received within slots 35 , 35 &# 39 ; ( not shown ) of drum heads 36 , 36 &# 39 ;. thus , drum heads 36 , 36 &# 39 ; and drum slats 34 with affixed sockets 33 comprise drum 40 . knockdown reel 30 can be completely disassembled and stacked in a relatively small space since drum 40 can be completely disassembled . once segments 32 are positioned within sockets 33 as shown in fig7 flange rings 38 , 38 &# 39 ; are urged over flanges 31 , 31 &# 39 ; and into ring grooves 39 . to provide additional strength and rigidity to reel 30 , axle 42 which also may be formed from suitable metallic or polymeric compositions is positioned through drum 40 and secured therein by external locking nuts 43 , 43 &# 39 ; and internal locking nuts 44 , 44 &# 39 ;. as would be understood , locking nuts 43 , 43 &# 39 ;, 44 , and 44 &# 39 ; are tightenable on threads 45 , 45 &# 39 ; of axle 42 . as hereinbefore mentioned , flange segments 32 may also include tongue and grooved end ribs or other means to attach one to another as desired . the illustrations and examples provided herein are for explanatory purposes and are not intended to limit the scope of the appended claims .
