Abstract: A distributor for receiving an air suspension of fibers and uniformly spreading them over a moving forming wire. Upper and lower parallel rotors in the distributor have parallel axes and rotor bars. The lower rotor is rotatable to distribute fibers through screen openings in a lower curved housing wall over the wire. The upper rotor bars pass in close proximity to a breaker bar extending into the distributor, and against which breaker bar clumps of fibers too large to pass through the screen openings are impacted and broken down into individual fibers capable of passing through the screen openings.

Abstract: A carton incorporates a new product release film into its tear strip, and greatly improves performance of the tear strip. The release film is uniaxially oriented, and is aligned with the tear strip, thus controlling tear strip function. Weakening cuts in the paperboard of the tear strip can now be significantly modified for manufacturing efficiencies, while the composite tear strip has enhanced performance and reliability.

Abstract: A method and system for applying a foamed binding agent to a fibrous web is disclosed. The invention is characterized by the use of an extruder having an upper lip extending 1/16 to 1/4 inch beyond the lower lip, and by the drawing of a vacuum beneath the applied foam, said characteristics being critical to the formation of a uniform foam layer atop the web. A second, more substantial vacuum is then applied beneath the web to essentially completely draw the binding agent into the web thereby providing substantial inter-fiber bonding.

Abstract: A carton has side and bottom walls of generally rectangular configuration, a pair of dust flaps hinged for closure on opposed side walls, and a pair of closure flaps hinged on opposed walls perpendicular to the first, for closure over the dust flaps. The dust flaps are constructed and arranged to be hinged inwardly of the carton and include cut-out sections that receive neck portions of a dispensing bottle and a rotationally locked dispensing nozzle thereon to hold the nozzle in place and to hold the bottle stationary as against movement about its base which is itself engaged, and held from shifting, by the carton side walls.

Abstract: Apparatus for forming a deep drawn paperboard container coated with a layer of grease and water impermeable polymeric material. A paperboard blank is disposed between and acted upon by a heated mandrel and a heated mold to form a container. The surface of the blank engageable by the mandrel bears the polymeric coating, and means are operative relatively to move the mandrel and mold toward one another, to engage, the blank, and, just prior to fully engaging the blank to set the same, to introduce a film of air between the heated mandrel and the polymer coated surface to ensure against sticking of the coating to the mandrel.

Abstract: In a multiple compartment carton, one compartment has a line of weakness for opening the compartment. Protective means overlies the line of weakness, to prevent inadvertent breakage of the line of weakness.

Abstract: In the manufacture of a multi-ply fibrous web structure, each of a pair of plies of fibrous web material is provided with a pattern of relatively deep, primary, spot embossments each adherent to the opposite ply and surrounded by a pattern of relatively shallow, secondary, non-adherent spot embossments.

Abstract: An improved bacon package is disclosed. The stiffening packaging element, commonly known as a bacon board, has full width top and bottom panels which support the bacon from the bottom and cover it over the entire top. Cover flaps on the ends of the top panel are defined by lines of weak bending resistance, and function to cover the ends of the array of bacon when the packaging element and bacon are enclosed in plastic films in a vacuum packaging operation.

Abstract: New bacon packaging is disclosed. The stiffening packaging element, commonly known as a bacon board, has full width top and bottom panels which support the bacon from the bottom and cover it on the top. Special cover flaps on the ends of the top panel are defined by transverse lines of weak bending resistance. The cover flaps, which function to cover the ends of the array of bacon, have segmental arcuate lines of weak bending resistance extending from the free edge of the cover flaps to the corresponding transverse line, and back to the free edge.

Abstract: Apparatus for the deposition of a uniform web of dry wood pulp fibers on a forming wire in combination with melt blowing die means operable to deposit melt blown fibers on the web of dry fibers to strengthen the web. Means for depositing the webs comprise serially disposed sets of fiber distributors, and the die means is disposed between the sets of fiber distributors so that the melt blown fibers are deposited as separate layers on the finished web.

Abstract: A conveyor for moving uniformly spaced-apart cylindrical articles transversely of their polar axes comprises a pair of parallel sawtooth rails, paired lifting and lowering levers on common pivots disposed along the rails in correspondence with each toothed portion of a rail, and cams for sequentially pivoting the lifting levers. The paired sawtooth elements include a stop surface and an inclined surface extending downwardly therefrom in the direction of article movement. The lowering lever is resiliently pivoted to an upper position independently of the lifting lever, and is downwardly pivotable by an article as it rolls down an inclined surface. Pivotation of the lowering lever to upper position permits the lifting lever gravitationally to pivot below an inclined surface.

Abstract: Apparatus for winding webs from a large-diameter roll onto cores to form smaller diameter rolls wherein the cores are supported on mandrels mounted at one end on a turret that is indexed between a core loading station, operational stations including at least a web winding station, and a wound-web unloading station. A pair of axially spaced star wheels keyed to a freely rotatable shaft having its axis parallel to the axes of the mandrels sequentially are engaged by, are rotated by, and are disengaged from a mandrel as it is moved between the core loading and winding stations to ensure alignment of the free end of the mandrel for supporting engagement with a provided latching cup operative to engage and steady the mandrel in the operational stations.

Abstract: Method for the manufacture of a fibrous web comprises provision of a conduit having a plurality of outlets for discharging classified fibers onto a linearly movable planar section of an endless screen. The fibers pass through openings in the screen and land on an underlying planar section of a forming wire, in formation of the fibrous web, with the aid of an underlying vacuum box. Uniformity of fiber distribution is provided by parallel banks of brushes that engage the planar section of the endless screen and are rapidly oscillated in short, non-synchronous strokes transversely of the direction of screen movement.
