    2.Press according to claim 1, distinguished by the fact that the bearing is connected to the body of the end bearing pivotally.
    3.Press p6 p. 1, characterized in that the bearing is connected to the body of the end bearing rigidly.
    4. Press according to claim 1, that is, so that the supports and the press shaft are located under the frame.
    The invention relates to presses with elongated grips for the press section of papermaking machines. A press with an extended clamp for the press section of papermaker is known. The machine includes a press shaft that is mounted in the end bearing on a frame oriented along its axis, - cling a shoe that forms a region of elongated grip with the press, with a device for guiding an endless felt cloth around the concave surface of the shoe into a pressing grip and an infinite good cloth covering the pressing shaft l). . The known press is unreliable in operation, and besides, the end pressures of the press shaft are often installed. not exactly. . . The purpose of the invention is to increase the reliability of operation and prevent the improper installation of the end bearings of the press shaft. The goal is achieved. The fact that in the press with an elongated. grip for the press part of the paper machine, containing the pressing shaft, the pins of which are mounted in the end subshapes. The keys on the frame, oriented along the axis of the pressure shoe, forming an elongated grip area with the pressing shaft, fitting the direction of the endless felt cloth around the concave surface of the shoe press grip and infinite canvas of cloth (the at least one of the end-shafts under the bearings of the press, which encloses the press shaft, has a support connected to its body, hinged on the frame, the axis of the turn-support is oriented in the direction of the paper web. The support is connected to the end bearing housing pivotally. In addition, the support is rigidly connected to the housing.The support and the pressing shaft are located under the frame. VIEW} in Fig. 2 is the same, cross section; in Fig. 3, a side view of Fig. 2f in Fig. 4 is a section A - A in - on. Fig. -2 ... Press with an extended grip for a press parts contains a press shaft 1 (4dag. 1-4), the trunnions 2 and 3 of which are mounted in the bearing 4 and 5 (Fig. 4). Under the press shaft 1 there is a press shoe 6, which has a concave surface 7 facing the shaft 1. The shoe, b, is installed with Swinging capability on a roller 8 installed in the piston 9. The piston 9 is placed in the groove 10, into which pressurized fluid is supplied. The shoe 6 is mounted on frame 11. The lubricant supply mechanism 12 supplies fluid to reduce friction between the concave surface 7 of the shoe b and the device for guiding the End Felt Cloth around the concave surface of the baishak into the press grip 13. The tape is 13 times. placed on the shafts 14g 17. One of these shafts is provided with a drive and driving the tape 13 through the istib formed between the shoe b and the shaft 1, at a speed equal to the speed of movement of the paper strip 18.. Over the bend, knives 19 are installed for removal; from the inner surface of the lubricating fluid tape 13. Lulosa paper 18 is positioned between the upper endless cloth 20 and the bottom endless cloth 21. The upper endless cloth 20 is guided by shafts 22 and 23, and the bottom endless cloth 21 is guided by shafts 24 and 25. Bearings 4 and 5 of the press shaft 1 have flanges 26 and 27 for screwing them onto the swinging supports 28 and 29. The support 28 (fig. 2) is held and the axis of rotation 30, passing in the direction of movement of the paper strip 8, the axis 30 of rotation is held in Am 31, the frame 31 is rigidly running along the entire length of the shaft 1 and is equipped with a side frame e by the elements 32 and 33, the position of which is adjusted in the direction of movement of the paper strips 18 in the direction of arrow B (Fig. 1).
    The support 29 is held at point 34 with the possibility of swinging by a hinge 35 pivotally connected to the frame 31 at point 36 (FIG. 2).
    As the shaft 1 deviates and the bearings 4 and 5 swing, the bearings shift across the machine, i.e. the distance between them is reduced. There is also a tilt of the bearings 4 and 5 with the pivots 2 and 3. Dp coM of this displacement and tilt. the supports 28 and 29 swing so as to restore the coaxial position of the bearings 4 and 5 and to provide an offset in the direction across the machine. This movement is provided by the support 29 and the hinge 35, which also provide the possibility of a thermal pact of HE in the direction across the machine and eliminates the need to take into account the thermal expansion of the bearing housings.
    The central keys 37 located in the grooves 38 position the shaft 1 in the direction of movement of the paper strip 18 and allow the bearing housings to be adjusted relative to the shaft shaft. Self-centering allows the encoders 4 and 5 of shaft 1 to have a high working capacity and eliminates reactive loads on the frame caused by misalignment.
     The bottom frame 11 is mounted by a lever 40 fixed at point 39 and a lever 41 fixed by point hinged at point 39.
    five
    On the supports 28 and -2 installed cleansing shaft knives 43.
    The frame 31 is equipped with a device 44 for removing the paper strip 18 from the shaft 1.;.,
    0
    The proposed press provides a long service life and eliminates the load caused by wear.
