One piece reel made by folding of a planar sheet

Abstract

A one-piece reel arrangement formed of a substantially quadrangle planar sheet is disclosed. The arrangement comprises longitudinal fold lines (A), transverse fold lines (B) and secondary transverse fold lines (E) neighboring to each of said transverse fold lines (B). Said fold lines (A, B, E) are formed by means of weakening the planar sheet material with perforations, incisions or semi-cut lines; wherein aforementioned fold lines (A, B, E) together form periodically repeating fragments along the longitudinal direction of the sheet. These fragments are adapted to be harmonically folded so that both longitudinal ends ( 4 ) are overlapped and attached to each other, and that reel body ( 3 ) and support legs ( 1 ) are formed by such folding.

1 . A substantially quadrangle planar sheet of a one-piece reel arrangement comprising longitudinal fold lines (A), transverse fold lines (B) and secondary transverse fold lines (E) neighboring to each of said transverse fold lines (B), said fold lines (A, B, E) being formed by means of weakening the planar sheet material with perforations, incisions or semi-cut lines; wherein aforementioned fold lines (A, B, E) together forming periodically repeating fragments along the longitudinal direction of the sheet, which fragments are adapted to be harmonically folded so that both longitudinal ends ( 4 ) are overlapped and attached to each other, and that reel body ( 3 ) and support legs ( 1 ) are formed by such folding. 
   
   
       2 . A planar sheet of a reel arrangement according to  claim 1  wherein said longitudinal fold lines (A) are in zigzag or sinusoidal form. 
   
   
       3 . A planar sheet of a reel arrangement according to  claim 1  wherein the periodically repeating fragments further comprise plain sectors ( 2 ) in between one or more transverse folds (B), whereby the longitudinal fold lines (A) are interrupted with longitudinal plain fold lines (D) of said plain sectors ( 2 ). 
   
   
       4 . A planar sheet of a reel arrangement according to  claim 1  wherein the periodically repeating fragments further comprise secondary inclined fold lines (C) which facilitate twisting of the reel support legs ( 1 ) when folded. 
   
   
       5 . A planar sheet of a reel arrangement according to  claim 4  wherein the support legs ( 1 ) are twisted in the inward direction. 
   
   
       6 . A planar sheet of a reel arrangement according to  claim 4  wherein the support legs ( 1 ) are twisted in the outward direction. 
   
   
       7 . A planar sheet of a reel arrangement according to  claim 5  wherein the support legs ( 1 ) are twisted in the inward direction such that said support legs ( 1 ) being oriented to each other, thereby wound strip material is closed by the twisted sections of said support legs ( 1 ). 
   
   
       8 . A planar sheet of a reel arrangement according to  claim 1  wherein the longitudinal ends ( 4 ) of the planar sheet are fixed to each other by attachment means selected from tape, glue, stapler, rivet and pin after harmonically folding of said planar sheet. 
   
   
       9 . A planar sheet of a reel arrangement according to  claim 1  wherein the planar sheet material is selected from metal sheet plates, planar plastic and composite sheets, and paperboards. 
   
   
       10 . A planar sheet of a reel arrangement according to  claim 9  wherein said paperboard is a commercially available corrugated or uncorrugated cardboard in rectangular or square shape. 
   
   
       11 . Use of the planar reel sheet as described in  claim 1  in storage and transportation of elongated strip form materials.
