This invention discloses a tight spinning device which can effectively concentrate the fibrous bundle. Its characteristic is as fellows, it has four rollers, and the first three rollers are same with the one of traditional ring spinning frame and the axes of the fourth parallel with the front roller, it is fixed before the front roller. There is a rolling drum on the surface of which are some small holes above the fourth roller, under the surface of rolling drum there is hypodermis squeezed. A wind shield is fixed on the perforated band of rolling drum with suction pressure, above the rolling drum a clearer roller presses on the surface of it. The effective result is that it can decrease the triangular space of twister and the feather of the yarn, improves the brute force of spinning. The range of spinning is large, the scope of the yarn is wide, the stability of the yarn is good, the additional equipment is not easy to wear out, and it is also suitable to modify the normal spinning machine to tight one.
