Title:
横断幅を有しかつ無限の長さを有するウェブを複数の使用供給形態へ変換する方法及び装置
Document Type and Number:
Japanese Patent JP4563529
Kind Code:
B2
Abstract:
An apparatus and method of converting a web (10) of definite length into a plurality of web portions by slitting the web at a transverse point prior to processing the web portions into a plurality of use supply forms (such as rolls), wherein the plurality of web portions are separated by a two-stage process. A first stage of the process is a partial separation operation that almost entirely separates the web portions, but leaves the web portions (26) connected, such as by a slitting operation that leaves a series of connected zones. The second stage includes the complete separation, such as by breaking of the connected zones. The complete separation of the web portions preferably occurs near the station at which the use supply forms are created, such as a winding station. Thus, the web portions, after substantial separation at the first stage can be handled (for example, guided and tensioned) as if the plurality of web portions were a full width web. But, after handling and transporting of the web portions to the use supply form station, the web portions are completely split so that the plural web portions can be wound or otherwise converted into a plurality of use supply forms.
