Abstract
A tabular negative pressure sheet 3 includes a baseplate 4, a sheet 5 with conduction grooves, a nonwoven cloth lamination outer layer 6, and a surface layer member 7. The baseplate 4 is a member as a base of the tabular negative pressure sheet 3. In addition, the sheet 5 with conduction grooves is a member disposed on the outer side of the baseplate 4, and on the surface thereof, negative pressure conduction grooves 8 are formed. In the tabular negative pressure sheet 3, negative pressure conduction grooves 8 are formed in a direction substantially perpendicular to a direction in which a strip 2 is threaded so that a negative pressure is generated as far as an end portion of the tabular negative pressure sheet 3.
Claims11
A negative-pressure sheet structure comprising:
- a main body to be provided on a metal slitter line;
- conduction holes which are provided inside the main body and in which a negative pressure is generated by a predetermined suction device;
- conduction grooves formed on a surface of the main body and connected to the conduction holes;
- and
- an outer layer portion provided on the outer side of the conduction grooves and having air permeability of 1.0 cm3/cm2/s or less in terms of Frazier air permeability with low air permeability.
