Abstract

The invention relates to the production of cores wrapped with a lengthy material. The invention allows the use of standard coils, simplify the design, improve the quality of the winding and reduce the labor intensity. A device for winding a core with a lengthy material contains a hollow mandrel 1 of core 2 and a ring 3, freely rotating on mandrel 1. Ring 3 is mounted spring-mounted relative to it and connected with it by hinge 4 a holder 5 with a guide 6. The holder 5 contains a freely rotating coil 7 with a lengthy material 8 and a tension roller 9 entwined with it, which contacts the hollow mandrel 1 and rolls around it. 2 Il. SL C

Description

The invention relates to the production of cores wrapped with lengthy materials, in particular plastic or ceramic drainage pipes forming drainage lines used in land reclamation construction.

The purpose of the invention is to simplify the design.

FIG. 1 shows a device for winding a core with a lengthy material, general view; in fig. 2 shows section A-A in FIG. one.

The device comprises a hollow mandrel 1 for core 2 and a ring 3 freely rotating on the mandrel 1, on which a spring-loaded relative to it is mounted and connected to it by hinge A, a holder 5 with a guide 6. The holder 5 contains a rotating catuppa 7 with a lengthy material 8 and an obv The tension roller 9 is in contact with the hollow mandrel 1.

A device for winding a core with a lengthy material operates as follows.

When the core 2 moves through the hollow mandrel 1, the lengthy material 8 attached to the core 2, winding from the coil 7, rotates the tension roller 9 twisted around it, which then rolls around the mandrel 1. The slipping of the tension roller 9 relative to the mandrel 1 is prevented by friction between them. When the roller 9 is rolled around, the casing 5 rotates with the guide 6 around the core 2 and is wound with a lengthy material 8 moving through the guide 6.

BUT

The device provides the necessary rational step of winding the core, regardless of the maximum diameter of the coil. A change in the coil diameter due to the consumption of a lengthy material does not affect the winding pitch, which remains stable over the entire length of the core, which improves the quality of the winding.

The device allows the use of virtually any standard coil with a long factory-made material, and the replacement of the spent coils is performed without breaking the core to be wound, which ultimately leads to a substantial reduction in the labor intensity.
