従動する間接駆動方式である。 When there is only one sheet of felt, the wet paper web W is dehydrated between the press roll 1 and one sheet of felt 2. Further, when two upper and lower traveling felts 2 are used, the wet paper web W is guided between the two upper and lower felts. 3
is pressed toward the press roll 1 from the outside of the traveling felt 2 by a pressure belt. This pressure belt 3 runs on guide rolls 4 that guide the press roll 1 forward and backward, and on a tension roll 5 that adjusts the tension of the belt.
6 is a pressure tool that presses the pressure belt 3 toward the press roll 1 from the outside of the running felt 2;
The pressurizing force is adjusted by adjusting the pressurizing source P. Furthermore, lubricating oil is supplied to the surface of the pressurizing tool 6 to reduce the frictional resistance against the pressurizing belt 3. The pressure belt 3 is driven by an indirect drive method in which it is driven by the positive drive of the press roll 1.
なお、7はベルトの加圧面の空隙内の水を吸収

により接続された有端状の網状基布が得られる。 The pressure belt 3 of this invention has a synthetic resin layer 40 layered on the back side of an endless net-like base fabric 31 made of synthetic resin spiral wire rods 30, and a felt contact surface 50 on the side of the net-like base fabric. It has many voids 34 on its surface. Net-like base fabric 31
A large number of spiral wire rods 30 made of synthetic resin are arranged in parallel in the width direction of the belt, and the adjacent wire rods 30 are interlocked with each other at their respective spiral portions 30', and a connecting core wire of synthetic resin is inserted into the common interlocking hole 32 formed. 33
Enter that. As a result, each wire 30 core wire 33
A net-like base fabric with ends connected by the above is obtained.

Monofilaments such as polyester resin and polyamide resin are used as the material for the synthetic resin spiral wire 30, and polyamide resin is particularly preferred from the viewpoint of wear resistance. As described above, this spiral wire rod 3
The net-like base fabric 31 made from zero becomes a net-like body having a predetermined size, high elasticity, large void volume, dimensional stability, and running safety.
上記網状基布31を有端状に形成したところ
で、これの裏面に第4図に示すように合成樹脂層
40を一体に層着する。 Once the net-like base fabric 31 is formed into an end-shaped shape, a synthetic resin layer 40 is integrally layered on the back side thereof as shown in FIG. 4.
合成樹脂層40は厚さが5mm〜15mmで硬度

に掛け渡す。 The synthetic resin layer 40 has a thickness of 5 mm to 15 mm and a hardness (JIS hardness) of 80 to 90 degrees. For example, an elastomer or liquid material such as polyurethane resin, acrylonitrile butadiene copolymer resin, or neoprene resin is coated on the network base fabric 31. laminated or coated on the back side. When the pressure belt 3 is used, it is stretched between the guide rolls 4 so that the net-like base fabric 31 side becomes the contact surface 50 with the running felt.

い。 After the synthetic resin layer 40 is layered as described above, both ends of the end-shaped net-like base fabric 31 are joined as described above to obtain an endless belt. 40 is glued with resin so that it is completely continuous without any breaks. Of course, the synthetic resin layer 40 may be layered after forming the net-like base fabric 31 into an endless shape.

点がある。 As can be seen from the above description, this device is a pressure belt that is pressed from the outside of a traveling felt placed on a press roll toward the press roll, and the pressure belt is made of a net-like base fabric made of synthetic resin spiral wire. Since the synthetic resin layer is layered on the back side, and the net-like base fabric side is the running felt contact surface, the wear resistance of the pressure surface (felt contact surface) of the belt is improved and the life of the belt is extended. During the lengthening process, a large number of voids 34 are formed on the pressurizing surface to receive the water that has separated from the felt, so that the water that has moved from the wet paper to the felt and has also separated from the felt can be smoothly drained. The dewatering efficiency of the parts is further improved. Furthermore, the spiral wires constituting the net-like base fabric can be freely joined to each other, so that it can be easily and easily loaded into a paper machine.
