本发明提供一种能够抑制网的断裂的适合于网自动卷绕机的网切断方法及网切断装置。网切断方法包括如下工序：赋予张力并搬送网；以及一边使切断设备的切断点在网的宽度方向上移动，一边将所搬送的网切断成上游网与下游网，且在切断网的工序中，在网的厚度方向上夹持相对于切断点的网的上游部分与网的下游部分，且使切断点与上游部分及下游部分的两个夹持点位于相同面上，并且，于切断点在网上的移动方向的后侧，限制被切断的上游网和/或下游网相对于网而朝垂直方向移动。; and moving a cutting point of a cutting equipment in a width direction of the web while cutting the transported web into an upstream web and a downstream web. Moreover, in the steps of cutting the web, clamping an upstream portion and a downstream portion of the web relative to the cutting point in a thickness direction of the web, and the cutting point and two clamping points of the upstream portion and the downstream portion are positioned at the same surface. Moreover, at a backside of a moving direction of the cutting point at the web, movement of the upstream web and/or the downstream web toward a vertical direction relative to the web is restricted. |
