Reel flange

Abstract

A reel flange is provided comprising wooden pieces (2A) disposed in a plane so as to constitute a disk and a connector (100) for maintaining said wooden pieces in the required position. The wooden pieces (2A) each have an overall sector shape which, when placed side by side, form a disk, and the connector includes a band (6) that presses onto the periphery of the disk and two plates centered on the disk that maintain the central area of the disk.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a reel flange.

It also relates to the reel obtained.

2. Description of Related Art

The packaging of wire in long lengths is done in coil form

To do this, the wire is wound, either on a mandrel that is temporary, i.e. used only to produce a coil whose characteristics result simply from the way in which the wire has been wound, or on a support also known as a reel.

Conventionally, a reel is constituted by two parallel flanges held the required distance apart by a central body onto which the filiform material is wound, at least indirectly.

This central body is generally tubular so that a spindle can be inserted into it in order to manipulate these reels.

These reels can be made of plastic, which requires the production of a relatively expensive mold.

But normally, the flanges are made of wood, a material that is relatively inexpensive and easy to work.

To produce these flanges, relatively large planks are used, disposed side by side so as to be held edge to edge by joining pieces that extend at right angles to the longitudinal axes of said planks.

Often, these joining pieces are also constituted by wooden planks forming a second layer of planks running crosswise to the first layer.

To give the assembly a disk shape, the outside edges of the planks are rectified, after assembly at the latest, so as to form a portion of the circle delimiting the disk.

Nails hold everything together.

The mechanical behavior of these layers is terrible.

Sometimes, a steel band is provided to limit wear on the flanges.

These reels nevertheless still require manual production.

One of the objects of the invention is to obtain a reel flange that is easy to construct.

SUMMARY OF THE INVENTION

To this end, the subject of the invention is a reel flange comprising:

wooden pieces disposed in a plane so as to constitute a disk, and

so-called connecting means for maintaining said wooden pieces in the required position,

this reel being characterized in that:

the wooden pieces each have an overall sector shape which, when placed side by side, form a disk, and

the connecting means comprise a band that presses on the periphery of the disk, and two plates centered on the disk that maintain the central area of the disk.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the drawing, we see a reel 1 .

Conventionally, a reel 1 is constituted by two parallel flanges 2 held the required distance apart by a central body 3 onto which the filiform material is wound, at least indirectly.

The central body 3 is generally tubular so that a spindle can be inserted into it in order to manipulate these reels.

In this case, the central body is a metal tube ( FIG. 2 ) or a wooden body (FIG. 4 ).

Each of the flanges 2 of the reel 1 comprises wooden pieces 2 A disposed in a plane so as to constitute a disk, and so-called connecting means 100 for maintaining said wooden pieces in the required position.

This flange also has a cutout 4 centered on its axis, 5 of rotation to make it possible to grasp it.

According to one characteristic of the invention:

the wooden pieces 2 A each have an overall sector shape which, when placed side by side, form a disk, and

the connecting means comprise a band 6 that presses on the periphery of the disk, and two plates 7 centered on the disk, which maintain the central area of the disk.

Advantageously, the band 6 has a U-shaped cross section such that the sides 6 A of the U laterally clamp the sectors 2 A.

This band 6 is made from a formed metal strip or a preformed section so as to have a U-shaped cross section, which is curved so that it takes the form of a hoop.

The two ends of the strip or section are then joined, preferably by welding.

Advantageously, the sector 2 A located in the area of the weld of the two ends of the band has a notch 8 perpendicular to this weld so that the wood does not run the risk of catching fire during the welding operation.

Advantageously, the plates 7 have an axial cutout 9 and one of them is welded to the end of a tubular crosspiece 10 .

More precisely, it is the external plate that is attached to the crosspiece 10 .

The second plate is held to the first one by bolts 11 passing through some of the sectors so as to form a hub.

The diameter of the axial cutout of the plate 7 located on the outside of the reel is equal to the external diameter of the tubular crosspiece to which it is attached by welding (see FIG. 3 ).

In the example represented, the aforementioned plate is not placed on the crosspiece but is slightly offset, and it is the welding bead 60 that provides the connection.

The other plate, the one pressing on the so-called internal surface of the flange, has a cutout 9 larger than the external diameter of the crosspiece 10 , and this plate is therefore held in place by bolts 11 whose shafts pass through the two plates and the wooden pieces so as to clamp the center part of the flange.

The internal diameter of the tubular crosspiece is approximately equal to the external diameter of the central body when the latter is mounted on a spindle.

The flanges are then attached to the central body by fastening means 12 so as to form a reel.

These fastening means could, of course, be embodied by weld points or a welding bead, but it is more advantageous for these fastening means to be demountable, like bolts 20 .

For this reason, the central body has, at a distance from each of its ends, a stop 12 A that extends at a right angle to the longitudinal axis of said central body and tie rods (not represented) that bring together the flanges, which thus come to rest on the aforementioned stops.

The stop 12 A has an external section identical to the internal section of the cutout 9 of the internal plate so that it can be wedged inside this cutout.

Preferably this cutout 9 is circular and the plate is square.

It is thus easy to exchange a reel flange if it is broken or to replace it with another one of a different diameter.

Sometimes, one of the sectors will be made of a material other than wood, such as metal.

As shown in FIG. 4 , another form of reel is represented.

As may be seen, the shape of the sectors can be substantially different so as to form the spokes of a wheel, between which said sectors of different dimensions are housed.

The narrower sectors can, for example, be made of a more rigid wood than the wider sectors.

The body of the reel is also made with wooden planks so as to constitute a cylinder 40 .

Plates 20 make it possible to connect and hold this cylindrical part 40 to the reel flanges.

Tie rod rods 50 are used.
