Thermoplastic elastomer nonwoven fabric roll, and method and device for producing the same

摘要

The thermoplastic elastomer filaments that have been melt-spun are laminated on the belt conveyor 115 thereby forming a sheet of nonwoven fabric 131, that is guided to the rotating roller 2 disposed above the transportation zone of the belt conveyor 115 and pulled off therefrom, while being wound around the paper tube 132 into the nonwoven roll 130. Since substantially the same tension as acting on the nonwoven fabric 131 serves as the pull-off force, the nonwoven fabric can be pulled off by applying only the minimum necessary tension to the nonwoven fabric 131. As a result, the nonwoven roll 130 with pull-off tension of 0.25 g/cm/weight or less that is subject to minimized longitudinal wrinkles and retarded restoration can be formed.
