Document Type and Number:
Japanese Patent JP2005248416
Kind Code:
A
Abstract:
To provide a method and apparatus for stabilizing the run in the drying section of a paper machine or the like.
A web 16 running from an opening nip between a cylinder 10 and a supporting fabric 18 toward a roll 14, is supported by a negative pressure created by a blow box 30. In an intensified negative pressure region 34', i.e. close to the disengaging point between the supporting fabric and the cylinder, the pressure is greater than at a distance from this disengaging point. The negative pressure is controlled according to parameters which act on the runability of the web and which can be varied, so the desired runability is maintained between the cylinder and the roll.
