Abstract
The reel comprises a core and two identical end plates fitted in and assembled on the core. It is characterized in that each one-piece end plate (2) has a cylindrical support (6) on its inside face, which support fits into the core (1), and a reserve housing (20) in its outside face, which housing communicates with the periphery of the core, and in that the core has an inside bevelled surface (5) of limited angle (b) on each of its ends Application: packaging optical fibers or electrical conductors.

In a reel for packaging a conductor, said reel comprising a tubular core and two identical end plates assembled onto said core, each end plate being of one piece and having projecting fitting means of an axial inside one of two faces thereof fitting into a bore of the core, and said core having radially inside bevelled surfaces on an axial inside face thereof, the improvement wherein said radially inside bevelled surfaces (5) extend over end portions only of the core (1) and are of limited angle (b) lying in the range of one degree to a few degrees, and wherein said fitting means are constituted by a first cylindrical support (6) having an outside diameter substantially equal to the mean inside diameter of each of radially bevelled ends of said core, said first support (6) has only on an end portion thereof, a radially outside bevelled surface (8) of angle (c) greater than the limited angle (b) of each of the radially inside bevelled surfaces (5) of said core, and said radially inside bevelled surfaces (5) of said core (1) are each of a length (h) substantially equal to the length of said first support (6).
In a reel for packaging a conductor, said reel comprising a tubular core and two identical end plates assembled onto said core, each end plate being of one piece and having projecting fitting means on an axial inside one of two faces thereof fitting into a bore of the core, and said core having radially inside bevelled surface son an axial inside face thereof, the improvement wherein said radially inside bevelled surfaces (5) extend over end portions only of the core (1) and are of limited angle (b) lying in the range of one degree to a few degrees, and wherein said fitting means are constituted by a first cylindrical support (6) having an outside diameter substantially equal to the mean inside diameter of each of radially bevelled ends of said core, said first support (6) has only on an end portion thereof, a radially outside bevelled surface (8) of angle (c) greater than the limited angle (b) of each of the radially inside bevelled surfaces (5) of said core, and wherein each end plate (2) includes a second cylindrical support (7) axially inside and coaxial to said first support and projecting form said axially inside face of the end plate, and a set of uniformly-distributed, circumferentially spaced axial fins (12) connecting said first support to said second support.
In a reel for packaging a conductor, said reel comprising a tubular core and two identical end plates assembled onto said core, each end plate being of one piece and having projecting fitting means on an axial inside one of two faces thereof fitting into a bore of the core, and said core having radially inside bevelled surfaces on an axial inside face thereof, the improvement wherein said radially inside bevelled surfaces (5) extend over end portions only of the core (1) and are of limited angle (b) lying in the range of one degree to a few degrees, and wherein said fitting means are constituted by a first cylindrical support (6) having an outside diameter substantially equal to the mean inside diameter of each of radially bevelled ends of said core, said first support (6) has only on an end portion thereof, a radially outside bevelled surface (8) of angle (c) greater than the limited angle (b) of each of the radially inside bevelled surfaces (5) of said core, and said radially inside bevelled surfaces (5) of said core (1) are each of a length (h) substantially equal to the length of said first support (6), and wherein each end plate (2) includes a second cylindrical support (7) axially inside and coaxial to said first support and projecting from said axially inside face of the end plate, and a set of uniformly distributed, circumferentially spaced axial fins (12) connecting said first support to said second support, wherein each axial end plate (2) has a radial flange (14) at the periphery of said first support (6), said radial flange being plane on a radially inside face of the and plate, except where said flange meets the first support and forms an axial inside circular abutment shoulder (15) of a width corresponding to the thickness of said core (1).
