2. Description of the Related Art The applicant has previously filed Japanese Patent Application No. 6-34096.
According to No. 1, while rotating the rotating body in one direction, the rotating body is provided so as to reciprocate an appropriate distance on the axis line, while a disk-shaped guide plate and a scraper are respectively provided on the left and right sides along the peripheral surface of the rotating body. While rotating at the same speed as the rotating body, supply a long fiber to be cut between the guide plates and wind it around the rotating body.While contacting the pressure contact body from the outside, the blade reciprocates inside to give a predetermined length. We proposed a fiber cutting device that cuts into small pieces and discharges the cut fibers to the outer circumference of the rotating body by the tip of a scraper interposed between the blades.

A press roller as a pressure contact member for backing up fibers cut from the inside from the outside by the above-mentioned reciprocating blade that is wound around the outer periphery of the rotating body while being wound around the tip of each blade. In the device of the above-mentioned prior application using the above, since the pressing position of the press roller is formed only at one position on the outer circumference of the rotating body with respect to one press roller, it is possible to suppress each blade arranged on the circumference from the outside. There was a drawback that the cutting force was low and the cutting efficiency was low.

Further, in the conventional apparatus, when the blades arranged on the peripheral surface of the rotating body have a wide interval (for example, 25 mm or more), a cut is provided between the blades and a fiber is formed at that position. It was possible to wrap it around the rotating body by sandwiching the start end, but when the blade spacing is extremely narrow (for example, 0.5 mm spacing)
Since it is impossible to provide a place to insert the fiber, it is difficult to wind the starting end of the fiber around the rotating body, and in any case, stop the device for winding the starting end of the fiber around the rotating body. However, there is a drawback that the operating rate is reduced.

SUMMARY OF THE INVENTION Therefore, according to the present invention, a large number of blades are radially arranged on the circumferential surface at intervals in the circumferential direction, and the blades are rotated in one direction while an appropriate distance is provided on the axis. The rotating body is provided so as to reciprocate, and is provided along the outer periphery of the rotating body. While rotating at the same speed as the rotating body, a strip-shaped long fiber wound around the rotating body is used to reciprocate the rotating body. A pair of left and right disk-type guide plates that prevent the coil from rotating at a predetermined winding position, and an intervening space between the guide plates from the outside of the rotating body, so that the fibers wound around the rotating body are pressed into contact with each other so as to be driven to rotate. An outer circumference of the rotating body, which is provided with the above-mentioned blade that reciprocates integrally with the rotating body, and a press-contact body that backs up from the outside that the fiber is cut into a length corresponding to the arrangement interval of the blade from the inside of the winding Along the outer surface of both guide plates Between the blades, forming discharge spaces for the cut fibers, and rotating at a constant speed with the rotating body and the guide plate at the same time, with the tips intervening between the blades to cut the cut fibers. In a fiber cutting device having a scraper provided so as to be discharged from between the blades, the pressure contact member is directed toward the peripheral surface of the rotor while being superposed on the outside of the fiber wound around the rotor. The present invention provides a fiber cutting device, characterized in that it is constituted by an endlessly circulating strip-shaped press-contacting body which is provided so as to form a press-contacting section having an appropriate length for press-contacting.

According to the present invention, the fibers wound around the rotating body are pressed against each other by a band-shaped pressing member instead of the press roller.
The pressure contact section of the fiber extends over the entire section along which the strip-shaped pressure contact body is arranged so as to be wound around the outer periphery of the rotating body. Therefore,
Since a large number of blades arranged on the circumference are backed up for cutting at the same time, the cutting ability is significantly improved. Further, if the next fiber can be supplied by being attached to the strip-shaped pressure contact member that circulates toward the rotary member, the automatic supply of the fiber becomes possible.
