Abstract: A method and an apparatus is disclosed for forming a multi-layered container of compressible sheet layers, such as corrugated board. The containers are formed in a single operation and avoids the known techniques of folding the layers before laminating in multistep methods. Furthermore, the container may be folded without the layers separating. The method of forming a multi-layered container having a plurality of flat sides with corners between adjacent sides comprises winding compressible sheet layers on a forming mandrel. In the process, one edge of a layer is attached adjacent to a corner of a mandrel, a shoe plate applies pressure to the layer against the mandrel as it rotates to maintain a substantially constant pressure and tension on the layer. An additional momentary force is applied to the shoe plate as each corner of the mandrel passes over the shoe plate such that the layer at each corner is compressed.

Abstract: There is provided a space divider which is made from a blank by a process in which various panels and tabs are defined by score lines and lines of severing, and in which the automatic machine which makes the space divider from the blank need only fold outer portions of the blank inwardly, and does not have to go through a zig-zag or fold-back operation. This means that a simpler mechanism can be utilized. There is also provided a space divider which utilizes less material than conventional space dividers, and which can be made of a depth less than the total depth of a carton while still being utilized both for the shipping of inverted empty bottles, and for the shipment of filled upright bottles. This is accomplished through the provision of registering fingers on the space divider, and a pair of apertures in the side walls of the carton, with which the fingers may alternatively register.

Abstract: A control system and a process is disclosed for a continuous wood chip downflow digestion system. The system maintains chip level in the top of the digester and maintains a consistency in the ratio of chips to liquor in the blowline thus allowing the system to run without constant operator attention. The system comprises a means for measuring the level of chips at the top of the digester and producing a level index over a predetermined time. This level index is compared with a preset level index and an error signal produced which operates a speed control means within preset limits for a rotating scraper feeding into the blowline. There is also provided a means for measuring the feed rate of chips to the digester, and a summating means for adding a predetermined ratio setpoint for the feed rate of chips against a flow in the blowline, to an integral of the error signal above or below a preset range to produce a summated ratio.
