Irrespective of the type of paper they contain all paper rolls are both valuable and sensitive to damage. Damaged paper rolls cause unnecessary and avoidable expense. Slower handling processes of damaged paper rolls can cause production loss. Furthermore damaged paper rolls often have to be rejected. Thus the paper industrys need for undamaged paper rolls is significant. iNcreased roLL weigHts The two most common causes of damage to paper rolls are moisture and mechanical impact. Paper rolls may become distorted by falling heavy impact or perhaps by pressure from paper clamps. During the roll transportation process steel stops and mechanical stoppers are further sources of damage. Increased paper roll sizes and roll weights are important additional factors that impact the paper roll handling quality. Today for example newsprint rolls may weigh up to 10 tons while 20 years ago their weight was typically less than 3 tons. In most cases old paper roll handling equipment had been designed for these smaller rolls and consequently does not have the capacity to handle the modern-day heavier rolls appropriately. Old outdated paper roll handling equipment needs replacing with equipment that has been especially designed to cope with heavier rolls. roLL HaNdLiNg By Mikko rantanen CEO MoveRoll Oy world pulppaper94 Improving roll receiving processes through absorption of kinetic energy traditioNaL roLL receiViNg process Generally paper roll receiving processes pose a major challenge to the ideal of damage-free paper roll handling. When MoveRoll started to analyse the roll receiving process in 2012 the following conclusion was reached paper mills typically use either fixed steel plates or mechanically powered units to receive paper rolls. Over the course of the last 60 years these two types of receivers have only seen minor improvements and adaptations to meet the requirements of higher roll weight and higher roll speed. When paper rolls for example leave the winder they move down a ramp taking on more speed through the rolling movement before they hit against a bare fixed steel plate. The energy is is not absorbed the roll will bounce back and forth and it is friction that eventually stops the rolls from moving. The hard impact can lead to distortions of the roll shape or possibly a damaged core meanwhile the friction may lead to tears and cuts. In addition the bouncing of the rolls can cause severe health and safety risks. Mechanical receivers on the other hand encounter problems with adjusting to different roll weights and speeds. Different energy is needed to receive rolls well that have different weights sizes and move at different speed. Typically the receiving capacity of mechanical receivers has been oversized The units cannot recognise the roll weight and as a compromise operate at the same speed regardless of the actual old outdated paper roll handling equipment needs replacing with equipment that has been especially designed to cope with heavier rolls
