Abstract
Abstract Apparatus for receiving single or multiple bundles of corrugated board blanks from a corrugator in which the bundles are automatically picked up and in the preferred embodiment stacked on a cart, with alternate bundles being placed upside down with respect to the orientation of their delivery to the mechanism. The disclosed mechanism is capable of handling full, corrugator width, single bundles of board or a plurality of less wide bundles at one time, thus obviating the necessity of having extremely high speed handling equipment or large off-bearer crews to handle the production from a corrugator. The bundles themselves, when stacked on the cart or truck, are placed in striated form for ease of unloading at another position.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
164 words
The method of handling multiple blanks of corrugated paperboard that are accumulated from the exit of a corrugator into bundles with the plural bundles being ejected at right angles to the machine direction of the corrugator, comprising the steps of: grasping a group of at least two of said bundles, on opposite sides along the longitudinal dimension of said group of bundles and wherein said bundles have identical transverse dimensions; moving the grasped group of bundles to a remote position overlying a stacking position; releasing said group of bundles at said stacking position; simultaneously with the moving of said group of bundles to said remote position, shifting said group of bundles sequentially and alternately to the right and to the left to thereby cause formation of a stratified stack at said stacking station having layers horizontally displaced to the right and to the left relative to the vertical centerline of said stack in an alternating pattern; and repeating the foreGoing steps in overlapping sequence.
Claim 2
Independent Claim

Claim 3
Dependent Claim
26 words
The method of claim 1 which further includes the step of: rotating every other group of said bundles through 180* during movement to said remote position.
