(57) Abstract:Usage: the invention relates to a marking modules extruding the profile of flexible material for the marking of electrical wires, cables, hoses and other elongated objects. The inventive module contains the Central part, oriented along the longitudinal axis on each side of the longitudinal part. Profile before marking has the form of a strip and is configured to bend the strips located between the Central part and the locking means. When bending profile get essentially the profile is triangular in shape, covering an elongated object when snapping the locking means. A marking module enables efficient labeling of various elongated objects having different thickness without the risk of slippage along the elongated product. 6 C.p. f-crystals, 5 Il. The invention relates to a marking module extruding the profile of flexible material for the marking of electrical wires, cables, hoses and other elongated objects, containing the Central part, oriented along the longitudinal axis of the profile.On famous is also known device, which is used to perform marking and making bulleted module. Also known devices and methods for the implementation of the elongated marking of products using an electric hand tools or machines. Known even marking electric cable by screwing the differently colored and/or labeled bushings on the cables. These bushings are stored in boxes with different branches near the installation tool and clamp or screw on the cable. Two examples of such labeling is described in SE N 7804949-1 and US N4641443, which explains marking profiles attached to the side.Marking system, mentioned above, are flexible, but require a lot of time for installation. It is also known that the use of already marked sleeves containing the identification number, requires a more or less long time, but is not flexible due to the fact that they need to prepare in advance according to the specification.For a long time there is a need for an identification system that is both efficient in terms of time, and flexible. In SE N456199 described solution, which for some premie using a pair of marking forceps, which deform the sleeve, consisting of several colored layers.The aim of the present invention is a marking module that combines the advantages of known main types.The advantage of the proposed marking module is that it has a locking means, which is parallel to the longitudinal axis on each side from the Central part, which make it possible, by mutual coupling, the formation of the profile of a closed hollow section, and that the thickness of the material profile is set so that it was flexible in the Central part and hard in the locking means.In Fig. 1 shows a spatial view of the marking module of Fig. 2 a spatial view of the marking module in a ribbon-like flat condition of Fig. 3 is a view of the marking module profile, fully locked in position for the smallest cable size; Fig. 4 a view of a marking module profile having one external locking means locked in position for the cable with the largest diameter; Fig. 5 shows how the marking.A marking module consists of extruding the profile from a flexible material, which includes Tsentralnoye longitudinal axis 13. The Central portion 4 through the grooves for bending moves in the lateral parts 11, which is parallel to a specified longitudinal axis 13 between the Central part 4 and the locking means 3 made on each side of said piece. After mutual engagement of the locking means 3, the profile forms a closed hollow profile, which covers the conductor 12.Material thickness profile is set so as to provide flexibility in the Central part 4 and the rigidity of the locking means 3.The profile set on the conductor 12 to the side, which facilitates installation.Method and device for the implementation of the marking should be compact and feasible so that marking symbols can be fixed by marking the profile in the place of their application in accordance with user requirements and taking into account their flexibility.According Fig. 1, a marking module contains prooobably profile 1, which is bent along the grooves 2 for bending around the cable 12 in a triangular shape, which covers the cable and which are snapped together by means of locks 3 formed on the sidewalls (shanks) 11. The triangular form is received, in part, through grooves 2 for bending and frequent the cauldrons in Fig. 3 are locks exciting type with two locking halves 3 symmetric form, in which the number of male locking elements and their angular pointy part is designed to get the best possible homing.The marking can be adapted to a wide range of sizes, since the locking can be carried out stepwise. In unbuttoned the position of the internal locking step is to follow the circumference of the conductor, see Fig. 4. Himself a closed profile is triangular in shape, in combination with length marking module, you can extend that makes it adaptable to a large number of cable diameters.The profile is preferably made of a transparent plastic material, for example, monomer SURLYN and marking symbols applied to the Central part 4, i.e., the rear side of the lock, internal/cable side of the module. On marking symbols near the cable is glued to the protective film 5 in a contrasting color. Therefore, the protective film 5 can function as a tool to determine the grooves to bend.Another variant implementation is obtained by marking characters on a transparent p is asty color.The third option for implementation is obtained by marking the upper and outer surface of the profile with a protective film or without it.Marking symbols is applied, as shown in Fig. 5, marking the profile the way in which he performed nesognutoy prooobably profile comes with a certain contact pressure in contact with an electric cylinder 6 thermal together with colored tape 7, further profile laminated together with adhesive film 5 by means of two compression rollers 8, one of which is a leading. Then marking the profile cut to desired length.The device shown in Fig. 5 for the above-described method, contains electrically operated portable unit, mainly containing keyboard or similar block selection characters, e-cylinder, 6 thermal, motor feeder and the feeder gripping roller 8 for laminating and marking the supporting roller 10, the electronics for mass storage devices and programming, display, separating knife 9, the cassette containing a strip of coding profile, color tape and self-adhesive protective film, it's all enclosed in one or more protective cases. Golo is.In Fig. 1 to 4 are shown at high magnification of the Central part 4 and the sidewall 11. In a real situation, these parts have a thickness of 0.1 to 1 mm, the Material of the locking means 3 is thicker than in parts 4 and 11.The invention is not limited to the above variants of implementation, other choices are possible within the scope of the attached claims. For example, the Central portion 4 can go directly to the locking means 3 without releasing the lateral parts. In addition, a marking profile may contain a layer of compressible material, for example, phenoplastic, allowing you to use the same marking profile for marking various elongated products with different thickness without the risk of slippage along the elongated product. Alternatively, the Central section 4 and the sidewall 11 can be provided with a layer of double adhesive tape for fixing the marking module in recordak narrow profile. 1.
