APPARATUS FOR SUBDIVIDING A RUNNING WEB OF COHERENT PANELS IN ZIG-ZAG FORMATION |
摘要 |
Successive panels of a running web with panels in zig-zag formation are deflected into a duct wherein the panels gather into a growing pile on a vertically movable bottom wall. A severing tool is moved across the pile at a selected level above the bottom wall to sever the web along the fold line between two neighboring panels when the pile beneath the level of the severing tool reaches a preselected height. A spreading device is used to spread apart the panels immediately above and below the level of the severing tool to establish a clearance for entry of the tool. The panels above and below the clearance are clamped to prevent the tool from displacing and/or otherwise affecting such panels during penetration into the clearance and during severing of the web along the fold line between the panels immediately adjacent the clearance.
