Abstract

Use: for packaging and storing film and other strip materials. SUMMARY OF THE INVENTION: when inserts with a cylindrical outer surface and flanges are inserted into a sleeve with a cylindrical inner surface, knives fixed on the outer surface of the inserts are inserted into the material of the sleeve made, for example, of cardboard. 1 s.p. f-ly, 4 ill.

Description

The invention relates to the field of photography and cinematography and can be used for packaging and storing film and other strip materials.

The purpose of the invention is to provide reliable fixation during assembly and to increase assembly productivity1.

- In FIG. 1 shows an inventive coil prior to assembly; in FIG. 2 - coil after assembly; in FIG. 3 is a cross section of a sleeve in a joint; in FIG. 4 - option. making knives with teeth.

The coil consists of two inserts-prl-zedelchiki 1, with fixed knives 2, with each insert is provided with a limiting flange 3. Inserts half-hearts 1 are inserted into the sleeve 4 on both sides and the knives 2 cut from the inside into the sleeve 4, forming a solid reel.

The coil assembly is carried out as follows.

Option 1. A film and film or other strip material is wound onto sleeve 4 (in production) and packaged. Before use, depending

from the material (in the dark for films and films, in daylight for other materials), unpack, then install (on both sides) half-heart inserts 1 with knives 2, which in turn cut into while cutting from the inside bushings 4 and form a single coil. In this case, the half-core inserts 1 are installed before touching films or other types of materials in the form of strips by bounding flanges.

Variant 2, Into sleeve 4 (equipped with a mechanism for attaching the End of photo and film films to the sleeve), half-hearth inserts 1 with knives 2 are installed, which in turn cut while cutting from the inside of sleeve 4 and form an integral coil. After that, film and film are wound.

Depending on the width of the film and film or other materials, it is only necessary to change the length of the sleeve 4 (in production - the material used for the manufacture: none of the sleeve 4 is easily deformable and does not lose structural rigidity). Others (L

The types of strip materials can be: adhesive tape, paper rolls, electrical insulation materials, threads, etc., i.e. materials that are wound on a spool with the application of torque.

The use of knives (their number may be 2.3.4 pieces), mounted on half-core inserts, and installing them in the sleeve (in a round hole) allows for cutting with simultaneous cutting from the inside of the sleeve, which increases productivity assembly, reliable fixation occurs during the formation of a single coil.

The use of the proposed device to implement the proposed method will save plastic, because It is used for films of different widths, while the half-core inserts remain unchanged, only the sleeve is variable. In addition, the reel is very convenient to use, as rewinding is avoided.

films and other materials from roll to reel. The proposed device will be widely used both among film enthusiasts and in other areas of the national economy.
