Document Type and Number:
Japanese Patent JP2686852
Kind Code:
B2
Abstract:
A vacuum roll apparatus is disclosed for transferring a web supported on a dryer felt from a first to a second drying cylinder of a dryer section. The apparatus includes a rotatable perforate shell having a first and a second end, the shell defining a cavity which extends from the first to the second end of the shell. The arrangement is such that the dryer felt extends from the first dryer around the perforate shell to the second dryer with the web extending contiguously with the dryer felt, and the dryer felt being disposed between the shell and the web. At least one fin is rigidly secured to the shell and is disposed within the cavity such that when the shell is rotated, the fin generates a flow of air through the perforate shell towards the cavity for drawing the web into close conformity with the dryer felt during movement thereof around the vacuum roll apparatus so that the web is restrained against cross-machine directional shrinkage.
