Abstract:
Disclosed is a method to form arbitrarily shaped, uniform, lightweight, thermally insulating and acoustically absorptive automotive components with controllable density, thickness, porosity, and surface integrity. The method is based on natural cellulosic fibers such as those found in cardboard and paper and uses a thermoplastic fiber and particle slurry to form fusible components. The method produces components having the benefit of commercially available thermoformed fiber mats or open-cell extruded foam components with excellent acoustical properties, enhanced thermal insulation, and are light weight, which limits engine inefficiency, and the high cost of such products so as to allow large scale implementation.
Abstract:
A reinforced paperboard tube is constructed by depositing a polymeric matrix with embedded fibers on a paperboard tube by use of pultrusion processes, resulting in a composite tube with a paperboard inner surface and a composite polymer/fiber outer surface. The resulting composite tube exhibits desired strength and dynamic properties greater than those provided by either the original paperboard tube or the added polymer/fiber shell taken alone. The composite tube is particularly useful in the manufacture of paper or other sheet or strand materials which are rolled onto tubes during manufacturing, since the composite tube allows a low-diameter tube upon which such materials can be wound at very high speeds without the dynamic instability that would otherwise result if plain paperboard or polymer tubes of the same diameter and length were used.
Abstract:
The invention includes an arrangement for manufacturing an elongated object (4) including, inter alia, a fibrous material, by compressing (7,8) a quantity of fibrous material provided with a binding agent and drying the compressed fibrous material by passing the material between the electrodes of a high-frequency drier (5). One electrode (12), preferably both electrodes (12, 13) of the drier is/are arranged to co-act with an electrode-heating device (16).
Abstract:
Apparatus for manufacturing sleeves of fiber pulp by passing fiber pulp through a nozzle including a mandrel extending through the nozzle and a reciprocating piston mounted on the mandrel to exert pressure on the pulp. Screen members are located on the interior surface of the nozzle, the exterior surface of the mandrel, and the end surface of the piston in conjunction with suction means to provide for dewatering of the pulp.
Abstract:
Consistently-automated production machines allocated in a pulp-molding production line and a method for prepare a dried paper article (i.e. a filter tip, a cartridge container, or a component of a packaging tube) is introduced herein. It can not only resolve the technical problems of the existing pulp-molding fabrication method that is incapable of producing an elongated cylindrical/tubular component, having a ratio, greater than one, of a maximum longitudinal height thereof being relative to a maximum transverse width thereof, but can also save its working cycle time, benefit its mass production, and assure its higher product yield and quality.
Abstract:
A container with a shell and lining within its interior is provided. The shell and/or lining can be fabricated from a biodegradable, recyclable, and/or compostable material. The lining can be configured as a parison, a preform, and/or other mass that is capable of being expanded. The lining can be inserted within a cavity of the shell and caused to expand to form an expanded state. The lining, in the expanded state, may be used as a barrier, preventing beverage that is inserted into the container from making contact with the shell. The lining, in the expanded state, may be configured to maintain contact with an inner surface of the shell so as to provide adequate shock absorption. The lining can be a thin film, providing an overall thinner construction and/or an overall lighter construction can be used to fabricate the container.
Abstract:
The present invention provides a core for receiving a wound product wherein the core is made of a waste sludge produced in a papermaking process. The process for making the core includes the steps of mixing the sludge with a binder material, which may be either a wet strength or a dry strength agent, and then compressing the mixture into a core through a process such as extrusion or molding. Optionally, the sludge may be dried prior to mixing with the binder material.
