When a leaf break occurs in any sector at the end of the machine, decreasing the width of the sheet to a strip just allowing this strip to be passed again at the point where it broke, after that they make the leaf widening again.
They are used to decrease the time lost when sheet breaks in the reels, nas calandras, in post-drying or sizepress.
Features and Advantages
The use of tip cutters makes it possible to decrease the width of the sheet to a size that allows only the cutter to pass on.. When there are no cutters, the sheet needs to be reduced on the flat table and needs to be passed in point from the flat table to the winder to later increase the width of the sheet.
It has been quite a long time to complete this cycle.
It can be estimated that with the use of sheet cutters the time of a break at the end of the machine is reduced to something around one third.
