    The invention relates to equipment for the manufacture of winding coatings, and to clamp thermoplastic plastic tapes to the surface of steel pipes to form a helix coating in the form of a helix. The limestone of the device for clamping the tape material when it is wound along a helical line on the surface of a cylindrical product, equipped with a pinch roller, which is made rigid FROM. Hard press rollers provide considerable pressure when clamping, which can cause damage to the winding tape. It is also known to have a press in the form of a roller containing a rigid axis, a cylindrical liner with holes mounted on it, and a casing made of elastic material C23. The known roller does not provide a secure clamping of the tape due to the possibility of damage to the tape and air inclusions under this tape. The aim of the invention is to ensure reliable clamping by eliminating damage to the tape and air falling beneath it. For this, with a roller containing a rigid axis, a cylindrical liner with holes and a shell made of an elastic material fixed to it, the liner is made of silicone rubber with a hardness of not more than 40 Shore and a shell of silicone rubber with a hardness of no more than 30 Shora, and the holes in the liner. They are evenly spaced in diameter and directed parallel to the axis of the roller. Figure 1 shows a longitudinal section of a roller; figure 2 is a cross section of the roller; figure 3 shows the position of the roller when the tape is wound on a pipe. The roller for pressing the tapes of thermoplastic material to the surface of steel pipes wound in a spiral to form a coating on them consists of a rigid axis 1, an elastic liner 2 made of silicate rubber with a hardness not exceeding 40 Shore, and a shell 3 made of silicone rubber with a hardness of not more than 30 Shore. The liner 2 and the shell 3 are produced by pouring rubber about axis 1. To increase the elasticity of the liner 2 has holes 4, which are evenly spaced in diameter and directed parallel to the axis 1 of the roller. The operation of the roller is carried out in the following manner. The pressure roller is pivotally fixed to the guide roller 6, which serves to bring the glue 9 to the surface of the pipe 7 leaving the strip 8 from the nozzle 8. At the same time, a thermoplastic tape is fed from the extrusion nozzle 10. 11, which, together with the glue strip, is laid along a helix on the turn: 4th of the pipe 7. The elastic roller, pressing the tape layers against the air inclusion pipe, is pressed and the tape material is not damaged. The use of a pressure roller of the design described above makes it possible to ensure a reliable pressure of a tape of a thermoplastic material wound on a steel pipe. Claims of the Invention Roller for clamping tapes of thermoplastic material to the surface V f.f / f-. steel pipes that are spirally wound to form a coating on them, containing a rigid axis, a cylindrical liner with holes and a casing made of an elastic material fixed to it, characterized in that, in order to ensure a reliable pressure due to the exclusion of damage to the tape and falling under air inclusions, the liner is made of silicone rubber with a hardness of not more than 40 Shore, and a silicone rubber shell with a hardness of no more than 30 Shore, with the holes in the liner evenly spaced in diameter and directed parallel to the axis of the roller.
