Document Type and Number:
Japanese Patent JP7029949
Kind Code:
B2
Abstract:
To efficiently manufacture a stretchable sheet by suppressing breakage of a tooth groove of a tooth groove roller when the sheet breaks.SOLUTION: A manufacturing method of a stretchable sheet 11 manufactures the stretchable sheet 11 by: supplying a substrate sheet 10 to an engaging part of a pair of tooth groove rollers 3a, 3b by a pair of infeed rollers 2a, 2b to extend the substrate sheet 10; and drawing an extended substrate sheet 10a from the engaging part while adding tension by a pair of outfeed rollers 4a, 4b. A breakage detection sensor 5 is disposed between the pair of tooth groove rollers 3a, 3b and the pair of outfeed rollers 4a, 4b in order to stop the pair of tooth groove rollers 3a, 3b and subsequently stop the pair of infeed rollers 2a, 2b when the breakage detection sensor 5 detects breakage during operation.SELECTED DRAWING: Figure 1
