Title:
【発明の名称】短縮されたセルロース構造体を製造する方法及び装置
Document Type and Number:
Japanese Patent JP2001527171
Kind Code:
A
Abstract:
A process and an apparatus for making a foreshortened paper web are disclosed. A wet web disposed on a fluid-permeable papermaking fabric is being pressed between two parallel and mutually opposed first and second press surfaces, the first press surface contacting the web, and the second press surface contacting the fabric. In the continuous process, the press surfaces, the web and the fabric move in a machine direction. Under pressure, at least selected portions of the web become densified and adhered to the first press surface which can be treated with a creping adhesive. The first surface is heated to create a temperature differential between two surfaces. The temperature differential causes the water contained in the web to move from the web into the fabric, thereby drying the web. After the web is released from the pressure, the web is foreshortened either by creping or by transferring the web to a slower moving transfer fabric. Creping is performed with a creping doctor blade juxtaposed with the creping surface having the web adhered thereto. A creping adhesive may be deposited on the creping surface according to a predetermined pattern. The creping surface may comprise the first press surface. Optionally, the web may be calendered after being foreshortened.
