High speed lidder

摘要

A lidding apparatus has a pair of brake shoes which elevate a box from a conveyor, the box being decelerated by the brake shoes. A lidding assembly includes an opposite pair of grooves with a release configuration for supporting a flat lid blank but allowing the flaps of the blank to rotate out of the grooves. The lid blank is maintained in a flat condition as the lid blank and box are bought into mutually centered contact whereupon the side flaps are rotated toward the box through the clearances provided by the release configuration by shoes of the lidding assembly.
