This paper analyzes the new technology of ending and mesh-bar placing in fully-mechanized face,and budgets the time of anchor rod support and withdrawing and inserting beams.

Some points including adjusting mining,mesh placement,upper port carrying framed timber constructing,support design of removing roadway,etc.

This paper analyzes the reason for web turned over, and also introduces the innovation project for lapping machine, it not only can resolve the phenomenon of web turned over, but also can raise the production speed of lapping machine from 70～80 m/min to 100～120 m/min.

The lapping machine is the important equipment of nonwoven production line, which affects the quality of products.

Gas flow structure of injection layering and calculating method of flow distribution by kinetics theory of gas jet current also be presented in it.

Combining the traditional usage of the cross lapper,the configuration,working principle,technical characteristics and advantages of the two directions′ inputing were probed.

It is mainly based on close and effective combination, from design to control to operation, of carding and cross lapping producing true and actual even nonwoven products.
