    The invention relates to drying # 1 cylinders for paper machines. . A rotary cylinder of a papermaking machine is known, comprising a shell with end walls mounted rotatably, a means for supplying steam, a means for removing condensate from the inner surface of the cylinder shell, including branch pipes fixed to the central axis of the cylinder 1, the disadvantage of the known drying The cylinder is a slow drying process. The purpose of the invention is to accelerate the drying process. The goal is achieved by the fact that the CUSHN cylinder of the papermaking machine containing the casing. rotatably mounted end walls, means for steam supply, means for removing condensate from the inner surface of the cylinder shell, including discharge pipes fixed on the central axis of the cylinder, have a pile element made in the form of a holder with a uniformly distributed pile fixed on it and mounted inside the cylinder parallel to its generatrix, and means for mounting the pile element located on the axis of the cylinder while the pile element is located radially inside the cylinder with a gap relative to its inner surface, not exceeding the thickness of the condensate layer. The means for mounting the pile member comprises brackets for fastening the pile member and radially arranged rods connected at one end to the bracket and the other to the central axis. The means for mounting the nap member is mounted on the central axis with the possibility of adjusting its angular position in the cylinder. FIG. 1 shows the proposed device, a general view; in fig. Fig. 2 shows the section A-A in Fig.; Fig. 3-a pile element; in fig. 4 - part of the drying cylinder. The drying cylinder of the paper machine contains shell 1 with end walls 2 and 3, the latter mounted on semi-axes 4 and 5 with the possibility of rotation. The direction of the heated steam flow is provided by the means 6 for supplying steam. When heat is transferred from the water vapor to the cylinder shell, condensate forms, which, at operating speeds of rotation, will form a layer on the inner surface of the shell 7. The condensate is removed from the inner surface 7 of the cylinder by means of condensate removal, including a discharge pipe 8 and a discharge pipe. siphon tube 9, mounted on the central axis 10 of the cylinder. The outer surface 11 of the shell 1 is smooth to support the paper web. In the cylinder, parallel to its generatrix, a nap element is placed, formed in the form of a holder 12 with an evenly distributed pile 13 fixed on it. The pile 13 is located radially inside the cylinder with a gap relative to its inner surface 7 not exceeding the thickness of the condensate layer. The means for installing the nap member comprises brackets 14 and 15 for fastening the nap member and radially arranged rods 16 and 17. The rods 16 and 17 are connected at one end to the brackets 14 and 15, and the other are mounted on blocks 18 and 19 fixed to the fixed center. . Oral axis 10. Blocks 18 and 19 are clamped on the central axis 10 by a tightening bolt 20. The pile element is located inside the cylinder at an angle oL. The rotational position of the pile element can vary. The droplets 21 roll off the pile element and, falling on the inner surface 7 of the cylinder, form turbulence in the condensate layer, destroying it. The preferred angle is d .ISO, at which optimum settling of the condensate occurs. Pile 13 is effective at any depth of condensate that may be resonant. However, the greatest degree of turbulence occurs at a condensate layer thickness of 0.18 (4.57 mm). For this, the stationary siphon tube 9 is radially adjustable in order to synchronously adjust the position of its outer End relative to the inner surface 7 of the cylinder. This is achieved by the fact that the radial siphon tube 9 slides in the retaining pas, the tube 22 and is adjustable
    fixed by tightening element 23, I.
    FIG. 3 shows a different shape of the nap member.
    To {) the onstate 14 is made in the form of an i-shape, having a spring 24, to which the support rod 16 is attached. The bracket 14 has lateral legs 25 and 26, the rear parts of the villi 13 are mounted in the second, and the clamping bolt 27 passes through the pile element to fix the pile, which is preferably made of stainless steel and other materials.

    FIG. 4 shows a drying cylinder with a shell 28 having ribs 29 and alternating grooves 30, Pile 31 of holder 32 alternately —I shortens and lengthens so that it projects to the base of each of the grooves 30 and is in close cooperation with the upper part of the ribs 29. Alternatively use a pile element with a pile of uniform length, which comes in contact with the ribs 29 and is deflected due to their interaction. In addition, a pile element with a pile located in the grooves 30 and above the ribs of the cylinder shell may be used.
