Abstract: Trimming apparatus for books and similar materials are detailed. Dynamic variability of the apparatus allows sizes of successive materials to differ in two dimensions—both from spine to face and from head to foot. The result is a processing system with substantially greater utility than presently available, as the system may process respective materials of multiple different sizes without stopping the apparatus to adjust positions of the cutting implements.

Abstract: An improved warehousing system whereby orders of material may be rapidly and efficiently filled and conveyed to a point of use or distribution. The system includes at least one elongated conveyor for moving material in a predetermined direction and an elongated walkway on at least one side of the conveyor in immediate adjacency thereto. A plurality of turntables, each having at least two angularly spaced material receiving stations are disposed immediately adjacent the walkway oppositely of the conveyor and are pivotally mounted so that a selected one of the material receiving stations may be disposed to face the walkway.
