Description

 The invention relates to equipment for the manufacture of products from composite fiber materials.

 Known winding device containing a winding machine, creel and bath for a binder (see AS USSR 1380992. A method of manufacturing large-sized flat products).

 The disadvantage of such a device is its small technological capabilities, since it can only perform the winding of flat products.

 There is another winding device containing a bed, a drive for rotating the mandrel, creel, bath for a binder and a carriage with a spreader (see N. V. Kulikov. The effectiveness of the use of fiberglass pipes in the mining industry. M: Nedra, 1968, p.16) .

 The device has great technological capabilities, because thanks to the carriage with a spreader on it, it is possible to wind both flat and bulk products.

 However, the positive result achieved in this device remains insufficient.

 From the patent of the Russian Federation 2060222, cl. In 65 N 54/64, 05/20/1996, also known is a winding device comprising a bed, a mandrel rotation drive, creel, a binder bath, a carriage with a spreader and a device for removing the binder from the tow surface, mounted on the carriage between the binder bath and the spreader .

 However, this device does not allow dividing the roving after impregnation with a binder into several beams during the carriage stroke and winding of the product.

 The claimed invention eliminates this drawback, and also provides for the twisting of roving beams with spindles in bundles during the course of the carriage winding of the product and untwisting the bundles at the beginning of the reverse carriage and their subsequent twisting in the other direction on the rest of the carriage.

 The specified technical result is achieved by the fact that the winding device containing the bed, the drive rotation of the mandrel, creel, carriage, bath for the binder, the device for removing the binder from the roving surface and the layout, according to the invention, it is equipped with a carriage mounted between the bath for the binder and the device for removal of a binder from the roving surface by spindles kinematically connected to a chain fixed to the bed.

 This allows you to get products with new adjustable properties - for example, pipes with a given borehole wall and increased strength sealing roving at the ends of the pipe, due to the alternation of winding on them twisted and untwisted bundles.

 The implementation of the device for spinning the roving in the form of spindles kinematically connected with the drive chain, fixedly mounted on the bed, simplifies the design of the winding device.

 Below, with reference to the accompanying drawing, describes the device according to the invention.

 The winding device comprises a bed 1, a drive 2 for rotating the mandrel 3, creel 4, a bath 5 for a binder and a carriage 6 with a spreader 7; it is equipped with a device 8 for twisting the roving 9 into bundles 10 and a device 11 for removing a binder from the surface of the bundles 10, for regulating the transverse dimensions, rigidity and coverage of the bundles with a binder.

 Devices 8 and 11 are sequentially mounted on the carriage 6 between the bath 5 and the spreader 7, which makes it possible to completely fill the voids of the bundles with a binder and to remove it from the surface of the bundles in front of the spreader.

 In an embodiment, the device 8 is made in the form of spindles 12 kinematically connected to the drive chain 13, fixedly mounted on the frame 1, through sprockets 15, 16, 17 and the shaft 18, mounted in the carriage 6.

 When the device is operating, roving 9 (for example, in the form of fiberglass) from the creel 4 passes through the binder in the bath 5, then through the device 8, and during the movement of the pickup 7 along the rotatable mandrel 3 it is twisted into bundles 10 of the specified transverse dimensions and stiffness, from which excess binder is removed in the device 11, after which the bundles 10 are laid out by the pickup 7 to the mandrel 3 rotated by the drive 2. The carriage 6 moved according to the specified program through the stacker 7 ensures winding of the product (shown in thin lines in the drawing) with the required characteristics, for example, with a given wall duty ratio.

 The implementation of the winding device according to the invention, by adjusting the transverse dimensions, rigidity and coverage of the binder bundles, provides products with new adjustable properties and, thereby, extends the technological capabilities of the device.
