BG110922A - A collapsible spool - Google Patents

Abstract

The invention pertains to a collapsible spool that can be employed to wind long flexible materials especially metal combs for binding. The spool comprises a pipe (1) with flangs (2) mounted at both ends and caps (5). Joining of each flang (2) to the cap (5) is by a ring (4) with juts (6) fitting in holes (7) made in each of the caps (5).

Description

Technical field

The invention relates to a detachable spool which can be used for winding various flexible materials, in particular for metal combs for which, after use, spool elements can be returned to the manufacturer for further use.

BACKGROUND OF THE INVENTION

There is a known set of elements for mounting spools, spools or the like (WO 02/074676 A1) for mounting and dismantling as well as for flanges at different distances. In one embodiment, it consists of a spacer tube with a thread at one end and a nut, and at the other of bolts or studs and nuts.

The main problem with the first variant is that the spacer tube must be threaded, which requires the tube to be material and have a thickness that allows the thread to be formed.

The main problem with the second option is that the bolts or studs do not have a surface on which to roll the material when it is soft.

SUMMARY OF THE INVENTION

It is an object of the invention to provide a retractable spool, the main elements of which can be reused.

The object of the invention is solved by creating a spool consisting of a central tube, two flanges, adhesive tape, segments and caps. Caps and segments allow multiple easy installation and removal of the spool. With two caps, four segments and an adhesive tape, the bobbin flanges are mounted to the center tube.

The detachable spool consists of a pipe and two flanges mounted on both sides of the pipe, the pipe and flanges being joined by two mounting adhesive tapes. Each flange is mounted to the pipe by a cap, wherein the fixing of each flange to the cap is through a segment, on which projections are formed, entering holes open on each of the caps and fixing permanently all the elements of the spool, after the adhesive tape is inserted.

The caps at one end have a cylindrical part, which is tucked tightly into the tube, and at the other end, they have a board that serves to secure the flange after the segments are inserted.

The spool can be dismantled by removing the adhesive tapes.

Spools are mounted and flexible materials are wound on them during the manufacturing process. After packing, the material spools are transported to customers using the wound material. The bobbins are disassembled and the flanges, segments and caps, which have low volume and high cost, are returned to the manufacturer.

The advantages of the detachable spool are that it can be wound with a variety of flexible materials and its main components are reused, which reduces the cost of materials and environmental pollution.

Explanation of the annexed figures

The invention is illustrated by an exemplary embodiment shown in the accompanying drawings, of which:

FIG. 1 is an axonometric view of the spool;

FIG. 2- represents an axonometric view of the cap;

FIG. 3- represents a rear view of the cap;

FIG. 4- represents a cross-section of the cap;

FIG. 5- represents an axonometric view of the segment;

FIG. 6- represents a partial cross-section of the assembled spool.

Examples of carrying out the invention

The detachable spool shown in FIG. 1 consists of tube 1, two flanges 2, adhesive tape 3, segments 4 and caps 5. The flanges 2 are mounted to tube 1 by means of caps 5, segments 4 and adhesive tape 3. Installation is carried out in the following order: Cap 5 is inserted into the central hole of the flange 2. In the openings 7, the two projections 6 formed on the segments 4 are mounted, fixing the flange 2 to the cap 5. Two flange 2 with the caps 5 and the segments 4 are mounted at both ends of the pipe 1, such as are fixed with adhesive tape 3.

Application of the invention

The detachable spool can be used for winding various flexible materials of long length, such as cables, wires, wires, yarns, metal combs for binding and the like.

Reels, drums and the like for winding flexible long materials can also be made on the same principle.

Claims (3)
