Document Type and Number:
Japanese Patent JP2553429
Kind Code:
B2
Abstract:
A dryer apparatus is disclosed for drying a pressed web. The apparatus includes a plurality of single tier dryer sections in which successive sections dry alternate sides of the web, the web being transferred between successive sections without any open draw of the web such that the web is uniformly dried on both sides thereof while the web is restrained against cross-machine directional shrinkage. Each of the sections includes a single tier of dryers with an intermediate roll disposed between each adjacent dryer. A dryer felt extends in serpentine configuration around each dryer and roll such that the web is disposed between the felt and each dryer for drying one side of the web. The felt is also disposed between the roll and the web with the felt in direct contact with an alternate side of the web. The intermediate roll defines a plurality of circumferential grooves for diffusing boundary air following the felt that would otherwise tend to lift the web from the felt extending around the roll. The arrangement is such that inherent machine directional shrinkage of the web during drying thereof inhibits crossmachine directional shrinkage of the web during movement of the web between successive dryers.
