产品描述
参数
特别适用于幅宽4米以上、车速300m/min以内（设计车速3800m/min)的高速纸机、复卷机、分切机的展纸。
多节意味着纸机幅度的增大，不需为保证刚度而加大辊径、转动惯量，从而使辊子的转动更轻便、灵活。最佳曲率保证最佳展纸效果。
曲率调整分手动、气动两种方式，均可在线调节。气动方式既可整体调整又可单点调整。
Used specially in the high speed paper machine, rewinder and cutting machine’s paper spread whose width is more than 4000mm, machine speed within 3000m/min(designed machine speed 3800m/min).
Multi-section means that it doesn’t need to increase the roller’s diameter and moment of inertia to ensure the rigidity when the paper width increases. It makes the roller’s rotation more easily and flexible. Best curvature ensures best paper spread effect.
Curvature adjustment has two ways of manual and auto which can be adjusted on line. Automatic function can be adjusted in whole or adjusted single point.
