    Procedure in the press section of a paper machine for changing a felt (20). The normal run of said felt (20) passes in a substantial part in spaces (K) under the floor level (T-T) of the paper machine hall. In said press section its lower roll (12) is rotatably carried in support by one or several cantilevered beams (30). In the procedure the frame inserts (38) carrying one end of said cantilevered beam (30) are first removed and then lifting means (33, 33') provided in conjunction with said cantilevered beam (30) is used to lift the guide roll or guide rolls (15, 17) coming to lie within the loop of the felt to be changed and located in the underside space (K), into an upper position (15, 15') to be adjacent to the cantilevered beam (30). After that the loop (50) of the new felt is spread out to the configuration implied by the rolls coming to lie therewithin, in which shape the felt loop (50) is pushed, using special equipment (40, 41, 42, 43, 44, 45, 46, 47), to encircle the rolls (12, 13, 14, 15 and 17) coming to lie inside the loop and around said cantilevered beam (30) through the space vacated by said removed inserts (38). Then the rolls (15', 17') lifted into the upper position are lowered with their lifting means (33, 33') into their operating position in the underside space (K), whereupon said frame inserts (38) are closed.

    The invention relates to a device for replacing a cloth in the press section of a paper machine, preferably in a press section of a closed loop with the majority of the path of the cloth enclosing the lower and upper groove leading rolls mounted rotatably on a support and placed next to the lower roll of the press, equipped with an open water-carrying surface and mounted for rotation in the lower zone located above the floor level,
    The aim of the invention is to increase the efficiency of the process.
    FIG. 1 shows the proposed device, side view; in fig. 2 is a section A-A in FIG. 1; in fig. 3 - view of the loop of cloth.
    The device for replacing the cloth in the pressing section of the papermaking machine, mainly in the press section of the closed-head machine with the majority of the trajectory of the cloth 1, covering the bottom 2-3 and top 1P 6 and 7 of the cloth-1Sch1e rolls mounted for rotation on a support and placed - adjacent to the NShKN1Sh roller of the press 8, provided with an open water-retaining surface and mounted rotatably in the upper zone of the floor above the floor level, including the upper at least one cantilever girder 9, one end of which is mounted on at least ONE insert 10 mounted with the possibility of its removal to replace the felt 1, and at least one lifting means with a cable element Pi drive 12 and contains connected to the drive wap 13 with drums 14, on which is wound a cable element for lifting the lower woven rolls. Nashyn in the upper zone, with the lifting means connected to the console beam 9 or installed inside it. The vehicle contains a carrying pipe 15 mounted with the possibility of lying (Enn using a handle 16 mounted at one end thereof connected with the supporting means 7, and a carriage 18 mounted so as to move along
    rail 19 and connected to the other end of the pipe 15;
    The lifting means is located in the same vertical plane with the corresponding drive roller.
    In the workshop where the papermaking machine is installed, there are foundations that form a basement room, L in width.
    The device works as follows.
    Worn cloth is removed by cutting the loop it forms. After this, a new cloth, wound on a pipe, is transferred to a position (in FIG. 3) in which the carrier tube 15 is placed on the cable of the supporting means 17 by means of a crane of the same means installed under the hood of the workshop. A new cloth can be wound on the tube. 15 in such a way that the pipe can appear both inside and outside sang cloth.
    To replace the felt, the rolls 5 and 3 are raised close to the rolls 6-8 using lifting means.
    First, the roller 3 rises to its upper position on the slider and is separated from the bearing supports. In this pololsenin, the roll axes are gripped by the cable element I1. After that, the roll 3 rises above the floor level. In the same way, roller 5 rises above the floor level.
    The new cloth, wound onto the carrier tube 15, is stretched using the handle 16, and the loop of the cloth occupies the position indicated in FIG. 1 dash line. The installation position of the cloth across the machine at this stage is indicated by the index L, j (fig.Z). In this position, the cloth is held or manually 1 by a special aid. The inserts 10 are removed from the side frame of the device, the cantilever beam 9 is held in a raised position. The support means creates a force in the direction shown in FIG. 3 by an arrow F causing the carriage 18 to move along the track 19,
    At the same time, with the clip NJ open, the loop of the cloth is guided to 1 m over the rolls 6-8. This makes it possible to set the loop of the cloth to the proper position with the rolls 3 and 5-8 around it, after which the handle 16 is used to wind the next portion of the loop of cloth from the tube 15.
    At the same time, the rolls 5 and 3 from the top position above the floor level are lowered on the cable elements I1 down into their corresponding bearing supports.
    After that, instead of the old cloth
    maybe a new cloth.
