  • Patent number: 10377115
    Abstract: To acquire a stretchable sheet having air permeability due to the presence of through-holes, with no hole formed through outer layers. There are provided: interposing a resilient film (30) that stretches and contracts, in a stretched state between a first sheet layer (21) having no elasticity and a second sheet layer (22) having no elasticity; and joining the first sheet layer (21) and the second sheet layer (22) together with a number of joints directly or through the resilient film by melting the resilient film (30) with ultrasonic fusion energy applied by a thermal fusion device from the outside of the first sheet layer (21) and the outside of the second sheet layer (22) to a number of joint regions with intervals, during the interposing. The resilient film (30) is supplied around a counter roll (63) so as to be supplied around the anvil roll (60), and the anvil roll (60) is accelerated to be faster than the counter roll (63) in peripheral speed to stretch the resilient film (30).

  • Publication number: 20130340925
    Abstract: The method of manufacturing the secondary paper roll for the tissue paper products including: a multi-ply forming step (51) of multi-ply forming single-sheets S11 and S12 from primary paper rolls, reeled out from the plural primary paper rolls JR in the continuous direction so as to form a multi-ply continuous sheet S2, a chemicals applying step (53) of applying chemicals to the multi-ply continuous sheet S2, a slitting step (55) of slitting the multi-ply continuous sheet S2 into each product width of the tissue paper products or several fold widths thereof, and a winding step (56) of coaxially winding the respective slit multi-ply continuous sheets S2 so as to form plural secondary paper rolls R of each product width of the tissue paper products or several fold widths thereof.
