Title:
METHOD FOR MANUFACTURING ELASTIC COMPOSITE SHEET
Document Type and Number:
Japanese Patent JP2023057490
Kind Code:
A
Abstract:
To provide a method for manufacturing an elastic composite sheet that imparts elasticity and at the same time reduces yawing, etc. of seals and improves appearance.SOLUTION: A method for manufacturing an elastic composite sheet includes: a stretching step of forming an elastic sheet by feeding a raw material sheet between a pair of tooth groove rolls that engage with each other with respect to the raw material sheet including an elastic material and applying stretching processing; a shrinking step of shrinking the drawn elastic sheet to be brought into a weakened elongated state after the stretching step; and a sealing step of merging the elastic sheet with another sheet in the weakened elongated state and partially joining them to form a sealing section spaced apart in a conveying direction.SELECTED DRAWING: Figure 1
