Abstract (en)
[origin: JPH02305747A] PURPOSE: To increase the winding speed of a film web by making average peak - valley height Ra of a surface of a covered contact roll less than 0.4 μm and making 10 HB larger than 2.5/62.5 in its Brinnel hardness. CONSTITUTION: A film reel is formed by supplying a film web 1 to a contact roll 3 and winding it on a winding core from this roll 3. The film web on this contact roll 3 and the film web on the periphery of the film reel are made contact with a pair of air displacement rollers 5a, 5b, and an air boundary layer 4 around the film webs on the contact roll 3 and the film reel is squeezed out. At this time, the covered contact roll 3 has less than 0.4 μm of surface average peak - valley height Ra and Brinnel hardness of larger than 2.5/62.5 in 10 HB.
