Abstract
A signature bundle hoist clamp with a pivot for rotating the bundle about its longitudinal axis to thereby selectively position the folds in the signature at either the top or bottom of the bundle, for instance. The clamp includes adjustable legs, and a bearing plate is rotatable on each of the legs and is presented toward the bundle for compressing the bundle and permitting the rotation mentioned. A combined thrust and radial bearing is interposed between the clamp legs and the bearing plate for the compression and rotation mentioned, and a releasable stop pin engages the bearing plate for positioning the bundle in the selected position mentioned. The entire assembly is arranged with a hoist.
