Condition is compared, and the extension of traffic flow becomes smaller.
In diffusion part 20, by the way that diffusion space 36 is arranged, so that the traffic flow sprayed from jetting nozzle 34 is mainly along the side MD
It is reached on mobile band 32 to gradually extending.In the following description, the region of the traffic flow in diffusion space 36 is known as transporting
Basin 38.In Fig. 2, transport basin 38 is virtually illustrated.
As depicted in figs. 1 and 2, in diffusion part 20, it is provided with the auxiliary jet 40 as air-flow generating device.Auxiliary jet 40 is set
It is equipped with the opening 40A of the slit-shaped long in the cd direction as opening portion.In diffusion part 20, in the direction MD of jetting nozzle 34
Side and side contrary with MD are each configured with auxiliary jet 40, the opening 34A of the opening 40A and jetting nozzle 34 of auxiliary jet 40
Side by side.
Auxiliary jet 40 is connect with air supply pipe 42, and the gas supplied via air supply pipe 42 is sprayed from opening 40A.
In diffusion part 20, so that being formed by air-flow from the gas that auxiliary jet 40 sprays becomes according to the transport sprayed from jetting nozzle 34
Stream flow velocity Vm controls the gas via the supply of air supply pipe 42 to auxiliary jet 40 come the mode of the flow velocity Vs determined.Diffusion part 20
In, to make emission direction and the gas of gas from the substantially parallel mode of the emission direction of jetting nozzle 34 auxiliary jet 40 be arranged.
Here, flow velocity Vs is preferably flow velocity Vm or less (Vs≤Vm), more preferably 1/10 or more of flow velocity Vm (Vs >=(Vm/10).By
This, in diffusion part 20, controls gas to the supply of auxiliary jet 40 so that flow velocity Vs becomes 1/2 (Vs=Vm/2) of flow velocity Vm.
In addition, configure the opening 34A of jetting nozzle 34 and the opening 40A of auxiliary jet 40 side by side in present embodiment, but
It is without being limited thereto, it is configurable to the side in the opening 40A of the opening 34A of jetting nozzle 34 and auxiliary jet 40 more than another party
The mode of collection face 32A far from mobile band 32 has difference of height.
As a result, as shown in Fig. 2, in diffusion part 20, and the gas sprayed from auxiliary jet 40 in diffusion space 36
It generates and approaches and along the air-flow of traffic flow around traffic flow (transport basin 38).It, will be by from auxiliary jet in addition, in Fig. 2
40 gases sprayed and the air-flow that generates virtually is indicated as airflow layer 44.
More root longs in the manufacturing device 10 constituted in this way, from molten resin spinning and Jing Guo cooling treatment and stretch processing

The plurality of threads transported in diffusion space 36 by traffic flow generates the variation of flow velocity in the inside of traffic flow,
But region big than around is changed in flow velocity, the entanglement that flow velocity changes more big then long filament is more.It is generated as a result, by trapping long filament
The tensile strength of the obtained non-woven cloth of web get higher.However, in the web being captured, if the entanglement of long filament
Become more, then the uniformity of non-woven cloth reduces.
In contrast, it for the diffusion part 20 for being provided with auxiliary jet 40, by the gas sprayed from auxiliary jet 40, is transporting
It is formed close and along the air stream of the traffic flow around defeated stream, changes big area in the flow velocity that the inside of traffic flow generates
Domain can inhibit the size of flow velocity variation.Accordingly, for for the web that trap portion 18 traps, the entanglement of long filament can inhibit
Become more, can get the non-woven cloth for realizing uniformity raising.
