Min~30m/min, lapping air draught wind speed 3.5m/min~7m/min；
Step 9, milling train preconsolidation：Fibre web has a bonding, intensity by milling train, and 80 DEG C~130 DEG C of rolling mill temperature；
Step 10, hot wind consolidation：It is sent into cylinder through drive roll by the fibre web of milling train, fibre web is consolidated by cylinder hot wind, is formed
Semi-finished product, 180 DEG C~220 DEG C of hot wind wind-warm syndrome；
Step 11, winding are examined：Semi-finished product are wound by winder, quality inspection post personnel is to the inspection of semifinished product；
Step 12, cutting packaging：Semi-finished product are cut according to customer requirement, form finished product, and as requested to finished product
It is packed.
