Abstract

PURPOSE: To prevent travelling paper from contacting with the peripheral surface of a paper roll and prevent contamination of the paper roll by mounting a blow box onto the paper roll and forming thin air-stream layer on the peripheral surface of the paper roll.

CONSTITUTION: A blow box 3 is mounted contiguously to the intrusion side of the travelling paper P on a paper roll 1. On the surface opposite to the travelling paper P on the blow box 3, a blowing port 6 which opens in the tangential direction to the peripheral surface of the paper roll 1 is formed. From said blowing port 6, air is blown-out in the direction of A point on the paper roll 1, with the thickness of ten microns and someWseveral milimeters, in layered from with the width in the axial direction of the paper roll 1. Therefore, the travelling paper P does not contact with the peripheral surface of the paper roll 1, so that generation of crimps on the travelling paper and contamination of the paper roll crimps on the travelling paper and contamination of the paper roll 1 can be prevented, and drying of the paint coated on the travelling paper P is accelerated, and production efficiency can be improved.
