is provided on the receiving plate 127 and when the knitted fabric w on the receiving plate 127 that has been moved away from the machine is removed this switch 130b controls the operation of the motor 51 so that the receiving plate 127 returns to the initial position the fabric detection switch 130b can be modified so that it can also be used as the fabric detection sensor 130a the motor 119 starts operation when the knitted fabric w has formed a full roll on the takeup shaft 20 in the state shown in fig2 when this occurs the motor 119 rotates the pulley 118 via the transmission belt 120 whereby the lifting screw shaft 117 moves the slider 121 threaded to it accordingly the pressing rods 121a of this slider 121 rotate the lifting struts 122 and 123 about their centers of their pin 125 so that they become more upright and the fabric receiving platform 126 and the receiving plate 127 are lifted to the upper limit as shown in fig2 the operation of the motor 119 stops when the knitted fabric detection sensor 130b detects abutment with the roll of the knitted fabric w then the takeup shafts 20 are pulled outward from the machine in the manner already described as a result as shown in fig2 the roll of the knitted fabric w is placed gently on the receiving plate 127 on the fabric receiving platform 126 when this occurs the knitted fabric detection sensor 130a operates and the motor 119 rotates in reverse so that the motor 119 rotates the pulley 118 in reverse direction via the transmission belt 120 whereby the lifting screw shaft 117 moves the slider 121 back to its original position then the pressing rods 121a.
