Research from the foundation concrete fabric pray phenomena analysis, foreign anti-segregation device was tested. Finally, the design of foreigners out of the box, developed a suitable fabric machine, two-door truck leaf spring type anti pray device off. The successful development of the leaf spring two-door anti-segregation device fabric machine to solve the years has been restricting the development of a technical fabric machine bottlenecks and improve the life of the fabric machine pipeline, reducing the occurrence of pipe blockage and improve concrete casting quality, to further promote the fabric machine has a very important significance. The agency has been a national patent. This design allows the fabric to the root of this machine is designed so that when walking Walking fabric feeding may need to drag the tail tape machine disassembly to walk without dragging on the material at the end of the tape machine running without disassembly, or on material tape machine pack walk on fabric tape machine. This innovative design for the band spreader localization of creating a way to protect the contents of the main fabric machine patent
