Abstract: A carton for packaging a series of rolls of web material includes parallel, opposite side walls and angled, corner walls provided at opposite corners of the carton. The rolls are positioned within the carton such that the material of the roll adjacent each corner wall engages the corner wall. Top and bottom end flaps extend from each of the side walls, for enclosing the top and bottom ends of the carton. Cut-out retainer flaps are formed in two of the top end flaps, for engagement within an internal passage defined by the core of the roll of material therebelow to retain the rolls of material in position within the interior of the carton.

Abstract: A tray-type package for receiving a series of articles is constructed from a blank which enables the user to vary the size of the horizontal surface on which the articles are placed. The blank includes a bottom panel and a series of side walls which are interconnected with the bottom panel via connection structure which defines a series of fold locations, and the user selects the appropriate fold location according to the size of articles being packaged such that, when a predetermined number of articles are placed on the tray, the outer articles are in close proximity to, or engage, the tray side walls. When the tray side walls are folded at the different fold positions, the position of the adjacent side wall ends varies, and retainer structure is interposed between the side wall ends which accommodates such variation and which secures the side walls together. The retainer structure is an extension section formed on one of the side walls which overlaps the other side wall.

Abstract: A device for aligning the shafts of adjacent driven and driver machinery units comprising a pair of congruent alignment plates connected to the coupling flange of each plate such that the axis of each shaft is normal to an identical point on each plate. A pair of centering bars positions each shaft with a coupling flange thereon in such position. Opposed keys on one plate are registered in corresponding keyways on the opposed plate by manipulation of the machinery. A gauge plate indicates any offset in the plates. Registration of the keys and superimposition of the congruent plates is achieved by machine manipulation to assure the user that an alignment in angularity and parallelism has been achieved. Bubble levels and dial indicator gauges are used in connection with the plates to enhance the alignment process.
