An air intake pipe f having a filter e is connected to the air collecting device c. A valve body g is horizontally mounted in the middle of the intake pipe f, and a pair of guide grooves h are formed in the valve body g. Further, in both of these guide grooves h, the shirt ter i is provided so as to be openable and closable by urging the vent hole g1 of the valve body g to be closed by the elasticity of the coil spring j. A pin shaft k is hung vertically through the groove g2 of the valve body g. Furthermore, a support shaft o constituting a ratchet mechanism n is pivotally supported on a mounting plate m which is integral with the valve body g, and a rotation shaft having a ratchet p and a plurality of adjusting screws q is supported on the support shaft o. The drum r is pivotally mounted. Further, a feed claw plate s is swingably mounted on the support shaft o, and a feed claw t is biased to the tooth part p1 of the ratchet p by a spring t1 on the feed claw plate s. It is pivotally attached so as to be locked. Further, a release u is connected to the feed claw plate s, and the other end of the release u is connected to a main control device in a circular knitting machine (not shown). The main control device operates the release u. The feeding claw t of the feeding claw plate s is intermittently pushed via the feeding claw plate s, and the feeding claw t is attached so as to intermittently feed the tooth portion p1 of the ratchet p one by one. Further, an operating lever v is pivotally attached to the mounting plate m by a pin shaft v1, and a bulging portion v2 of the operating lever v is formed so as to abut on each adjusting screw q. Moreover, the free end v3 of the actuating lever v is extended so as to come into contact with the pin shaft k against the elastic force of the coil spring j.

Accordingly, when the release u is intermittently pulled by the operation signal of the knitting control circuit, the above-described knitting fabric suction automatic control device causes the release u to move the feed claw t of the feed claw plate s 1. As the feed claw t is pushed and intermittently feeds the tooth portion p1 of the ratchet p one tooth at a time, the rotary drum r integral with the ratchet p rotates around the spindle o, and the rotary drum When the adjusting screw q of r pushes the bulging part v2 of the operating lever v, the free end v3 of the operating lever v pushes the pin shaft k against the elastic force of the coil spring j. Since it moves, the shirt shaft i provided with the pin shaft k is controlled to slide and open the ventilation hole g1 of the valve body g along the guide grooves h.
