【発明の名称】紙のウェブを製造するためのコンパクトなマルチレベル製紙機械
Document Type and Number:
Japanese Patent JP2003517115
Kind Code:
A
Abstract:
A compact multilevel paper making machine is provided comprising a web-receiving region where a web of paper is received on a fabric forming a continuous loop, a reel-up for winding the paper web onto a roll, and a web transfer point disposed between the web-receiving region and the reel-up. The fabric receives the web at the web-receiving region and then supports and transports the web from the web-receiving region to the web transfer point in a first direction on a first defined vertical level. At the web transfer point, the web is separated from the fabric. The fabric loop further includes a return run from the web transfer point to the web-receiving region over which the fabric then travels. A cleaning section is also disposed along the return run of the fabric loop for cleaning the fabric. Following separation from the fabric, the web is transported to the reel-up in a second direction, generally opposite to the first direction, and on a second defined vertical level different from the first defined vertical level. The second defined vertical level may be either above or below the first defined vertical level, wherein a defined vertical level may comprise, for instance, a floor of a building. Dryers are also provided before and/or after the web transfer region for drying the web and are accordingly disposed on the different defined vertical levels. Thus, by configuring the paper making machine to transport the web between different defined vertical levels, a compact multilevel paper making machine having a small footprint is provided for limited-space installations.
