1.前言 在纸厂中,复卷机主要负责对母纸卷进行复卷纵切的功能,也就是将造纸机卷纸部卷取的带铁心母卷通过复卷机分割成多套带纸心的小纸卷,复卷后的小纸卷既可以直接通过热塑打包成成品卷筒纸,也可以再经过切纸机切成平板纸。本文论述的是双底辊VARI—STEP复卷机,它能生产定量为30GSM～450GSM之间的各类纸和纸板,运行速度高达1800M/min,幅宽4300mm,最大复卷直径2100mm。图1所示为该系列复卷机的外观显示。
1. Introduction In the paper mill, the rewinder is mainly responsible for rewinding the mother roll, which is to divide the reeled winder into a plurality of sheets with paper The heart of the small paper roll, rewinding the small roll either directly through thermoplastic packaging into finished paper, paper can also be cut through the paper cutter. This article discusses the double bottom roll VARI-STEP winder, which produces a wide range of paper and board weights ranging from 30GSM to 450GSM with speeds up to 1800M / min, a breadth of 4300mm and a maximum rewind diameter of 2100mm. Figure 1 shows the appearance of this series of winders.
