Title:
MANUFACTURING METHOD FOR SHEET MATERIAL
Document Type and Number:
Japanese Patent JP2016221687
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enhance productivity of a sheet material.SOLUTION: A manufacturing method for a sheet material 1 includes a measurement process for measuring the state of the sheet material 1 flowing in a constant direction by measurement means 7 separated by a first distance L1 in a thickness direction of the sheet material 1 from a surface 1a of the sheet material 1. The manufacturing method further includes: a swollen section detection process for detecting a swollen section 11 swollen by the first distance L1 or more in the thickness direction of the sheet material 1 from the surface 1a of the sheet material 1 on an upstream side of the measurement means 7 before the measurement process; and a process for stopping the sheet material 1 before the swollen section 11 is supplied to the measurement means 7 by the detection of the swollen section 11.SELECTED DRAWING: Figure 1
