Larger parent rolls add line capacity
The parent roll size has a significant effect on overall material efficiency and capacity in the finishing area. By maximizing the diameter, it is possible to significantly improve output.
A fairly typical 2.8 m parent roll yields four sets of 1.3 m shipping rolls. Increasing the parent roll diameter to 3.7 m raises the number of shipping roll sets from each parent roll to seven. The material efficiency also increases by several percent, in addition to gaining plenty of extra capacity for removing existing bottlenecks in the finishing area.
