step 6, setting the feeding acceleration of the pinch roll: the control center sets the material conveying acceleration of the pinch roll according to the tail discharging speed of the laying head;
step 7, setting the feeding parameter speed of the head of the laying head through the acceleration of the material transmission of the pinch roll;
and 8, repeating the steps 3 to 7 until the pinch roll does not convey the material to the laying head any more, and closing the pinch roll and the laying head.
As a further preferred method of the invention, the pinch rolls are delayed from delivery by 0.5 seconds as the material on the pinch rolls is delivered to the head of the laying head.
As a further preferred method of the invention, the pinch rolls convey material to the laying head at a speed of from 95m/s to 105 m/s.
