To provide a first needling unit capable of more strongly compressing fleece before first dampening of fiber web.

A second endless belt 9 is arranged in a first endless belt 3 so as to travel in reverse direction and operation section 9' of the endless belt 9 is driven and circulated in same direction as operation section 3' of the first endless belt 3 and both operation sections 3' and 9' of both endless belts 3 and 9 are opposed so as to mutually form conical shape in extension part in the longitudinal direction and a fiber web on operation section 3' of the first endless belt 3 is gradually strongly compressed between advancing endless belt 3. The second endless belt 9 is pressed toward a turning roller of the first endless belt 3 and between both rollers 10, a crossbeam-like nozzle 14 is turned toward fiber web 7 compressed between both endless belts 3 and 9.
