Abstract: Apparatus for securing plastic film about a product including a curved forming plate, sealer means cooperating with the plate to form spaced discrete heat seals in overlapping portions of plastic sheet disposed about the plate and product, and transport means for reciprocatably moving the sealer means so that it remains in engagement with overlapped sheet portions and follows the path of movement thereof for a predetermined period of time.

Abstract: A system for slitting a parent web to form grooved rolls including movable shear slitters and a Coanda nozzle device for removing trim segments from the shear slitters.

Abstract: Water-borne inks containing shellac or copal in combination with a titanium ester chelate have excellent printability and bond strength when used as laminating inks.

Abstract: A system and method for venting cooling air from a plurality of filaments with which said air has been associated, employing a Coanda flow attachment means, including a Coanda flow attachment surface, to separate the filaments and air into respective streams, and then to divert said air stream in a direction away from said filament stream.

Abstract: Apparatus for removing trim from a conveying fluid medium including a conduit defining a generally rectangular shaped exit opening. A fluid flow attachment plate leads from the opening for redirecting movement of the fluid medium. A screen for interrupting movement of the trim and separating it from the fluid medium is attached to the fluid flow attachment plate.

Abstract: Apparatus for culling cant ends from a cant including a first conveyor upon which the cant ends are formed and a second conveyor which forms a gap with the first conveyor when the cant ends are positioned for transfer therebetween so that the cant ends will fall through the gap.

Abstract: A system for serially conveying discrete flexible articles including a plurality of sequentially activated Coanda nozzles disposed along an article flow path and article support means cooperable with the nozzles to propel and stabilize the articles.

Abstract: A system for transporting discrete articles such as paper roll products in a predetermined number of flow lines and consolidating the articles into a lesser number of flow lines.

Abstract: The invention is an improved lime slaker in which the lime is combined with the slaking liquor in a vertical conduit which extends below the level of the liquor in the slaker vessel. The slaking liquor is introduced into the conduit at a high velocity tangential to the interior surface of the conduit to flush the lime into the vessel. The slaker includes a vertical vent pipe that extends through the bottom of the vessel. In a preferred embodiment, the inlet of the vent pipe is surrounded by an entrainment separator. Removable covers permit convenient access for inspection and cleaning of the conduit and the vent pipe.

Abstract: Method for making a roll paper product formed from a web having a substantially uniform width and having a groove end and a boss end formed by the convolutions of the web.

Abstract: Apparatus for transporting strip material from a first location to a second location including a first conduit, a venturi device disposed along the first conduit and means for generating fluid flow in the interior of the first conduit through the venturi device. A second conduit leads from the first location to the venturi device and an auxiliary fluid flow generating means is provided for entraining the strip material at the first location and transporting it through the second conduit to the venturi device.

Abstract: A system for producing a bulky, soft and absorbent paper web wherein the web is directed through a first nip formed by two dewatering felts, a second nip formed between a dewatering felt and an imprinting fabric of a specified character, and a third nip formed between the imprinting fabric and creping surface.

Abstract: A system for producing a bulky, soft and absorbent paper web wherein the web is creped from a first creping surface, passes through a nip formed between a dewatering felt and imprinting fabric of a specified character and is applied to and creped from a second creping surface.

Abstract: System for assembling a divider box from a main body blank, separate end panels and at least one divider panel. The end and divider panels are delivered to a container-erecting station where the panels are secured to the main body blank while the container is being erected.

Abstract: A system and method are provided for continually preventing filament bridging between adjacent draw nozzles. The system comprises a heating element, generally in the form of a metal heating wire, which is disposed between adjacent nozzles and is positioned in the path of filaments attempting to bridge the nozzles. The temperature is maintained at a level high enough above the melting point of the filaments so that they will continuously and instantaneously melt when they contact the heating element.

Abstract: A device for sequentially dispensing sheet material from a primary roll and a reserve roll including rotatable dispensing rollers, at least one of the rollers having a groove therein, sensing means for entering the groove when sheet material from the primary roll is depleted and tucker means responsive to such movement to engage reserve roll sheet material and introduce it between the rotatable rollers.

Abstract: A method and a system are provided for producing a continuous liquid spray curtain which, when sprayed onto a moving surface, covers essentially the entirety of that surface without substantial streaking thereof. The subject spray curtain is produced by discharging a continuous air curtain at a relatively high velocity of at least 600 feet per second. A plurality of liquid streams are at the same time discharged from a liquid discharge means at a relatively low velocity of not more than about 20 feet per second. The air curtain contacts the liquid streams at a minimum contact angle of between about -10.degree. and about +30.degree., measured from the center line of the liquid discharge means. The contacting air curtain atomizes the liquid streams and forms the subject high velocity, uniform, liquid spray curtain.

Abstract: This invention is directed to a method for upgrading cellulose by treating same with a chemical to produce a cellulose sheet having substantially increased absorbency, bulk and softness properties. The chemical system comprises the reaction product of a cyanuric halide compound and an alkylene oxide compound, respectively.
