查询词典 paving

The plates are obtained by two steps: compound felt and hot pressing shaping. The opening, mixture, carding, net-paving and needling process that affect shaping process of the blending fiber needle felt are investigated. Then it is concluded that the fiber nets from the BC-272B carding machines are uniform when the rolling speeds of licker-in, cylinder, doffer roller of the roller carding machine are 900r/min, 850r/min and 15.6r/min separately. The fiber needle felt is in a good condition when the paving nets have 8 layers, the type of the felting needle is 30, the density of needling is 1800end/m2, and the depth of needling is 3mm.
