Apparatus and method for adjusting the track of a granule-coated sheet

Номер: US20120141657A1
Автор: David P. Aschenbeck
Принадлежит: OWENS CORNING INTELLECTUAL CAPITAL LLC

A method for adjusting the track of a granule-coated sheet includes moving a granule-coated sheet around a drum. The granule-coated sheet includes first granules. A track of the granule-coated sheet is sensed at the drum. A first signal is generated when the granule-coated sheet has moved off a pre-designated track. Second granules are applied to a lane portion of the granule-coated sheet prior to the drum in response to the first signal. The second granules make the granule-coated sheet thicker in the lane portion relative to a thickness of the granule-coated sheet outside the lane portion.

A granule applicator for an apparatus and method for applying granules onto an asphalt-coated sheet moving in a machine direction with improved resolution and edge definition of the applied granule patches and blends. In one embodiment a blend drop conveyor has an upper flight urged into a concavity by an outside, third roller. The conveyor is configured to receive granules at a first speed in an area near the convergence of the upper flight and the third roller, and to traject them on a second path at a second speed near the sheet speed of the substrate below. The applicator thus changes the speed and direction of the granules, to cause them to land on the substrate with good edge definition and minimal splatter.

The present invention relates to an absorbent structure, preferably for use in absorbent products, such as used in the food, consumer, household, building and construction, beauty and medical industry, and as used in the personal hygiene industry. The substantially cellulose free absorbent structures continuously immobilise absorbent polymer material via initial smaller pockets and subsequently larger compartments allowing excellent fluid management of the absorbent polymer material in dry, partially and fully liquid loaded state. Preferably such absorbent structure volume increases are result of temporary secondary attachment patterns made in combination with substantially permanent primary attachment grids allowing the release of bigger volumes from the initial smaller volumes by detachment of the secondary attachments. Furthermore the absorbent structure according to an embodiment of the invention non-homogeneously swells to form a liquid-managing surface structure as a result of exposing the absorbent structure to liquid. The present invention foresees in the need for improved flexible, thin, lightweight absorbent structures which overcome the absorbency problems of the prior art during absorption, distribution and retention of liquids with optimal fit.

The substantially cellulose free absorbent structures continuously immobilise absorbent polymer material via initial smaller pockets and subsequently larger compartments allowing excellent fluid management of the absorbent polymer material in dry, partially and fully liquid loaded state. Preferably such absorbent structure volume increases are result of temporary secondary attachment patterns made in combination with substantially permanent primary attachment grids allowing the release of bigger volumes from the initial smaller volumes by detachment of the secondary attachments. Furthermore the absorbent structure according to an embodiment of the invention non-homogeneously swells to form a liquid-managing surface structure as a result of exposing the absorbent structure to liquid. The present invention foresees in the need for improved flexible, thin, lightweight absorbent structures which overcome the absorbency problems of the prior art during absorption, distribution and retention of liquids with optimal fit.

A powder-rubbing apparatus comprises: a rotatable rubbing roll having a rotational axis; a substrate path; an oscillating mechanism for oscillating the rotatable rubbing roll along the rotational axis; and a powder coating die comprising an inlet port in fluid communication with an outlet port disposed adjacent to the substrate path. The substrate frictionally contacts the rotatable rubbing roll within a rubbing zone. A dispenser for dispensing gas-borne powder is in fluid communication with the inlet port of the powder coating die. The dispenser is aligned such that at least a portion of a gas-borne powder dispensed from the powder coating die is deposited directly onto at least one of the rotatable rubbing roll or the substrate and conveyed into the rubbing zone. A method of using the powder-rubbing apparatus and a powder-rubbed web preparable thereby are also disclosed. 1. A powder-rubbing apparatus suitable for making a powder-rubbed substrate , the powder-rubbing apparatus comprising:a rotatable rubbing roll having a rotational axis;a substrate path for conveying the substrate in a machine direction into frictional contact with the rotatable rubbing roll within a rubbing zone, wherein the substrate frictionally contacts the rotatable rubbing roll within the rubbing zone;an oscillating mechanism for oscillating the rotatable rubbing roll along the rotational axis;a powder coating die comprising an inlet port in fluid communication with an outlet port, wherein the powder coating die is disposed adjacent to the substrate path; anda dispenser for dispensing gas-borne powder in fluid communication with the inlet port of the powder coating die, wherein the dispenser is aligned such that at least a portion of a gas-borne powder dispensed from the powder coating die is deposited directly onto at least one of the rotatable rubbing roll or the substrate and conveyed into the rubbing zone.2. The powder-rubbing apparatus of claim 1 , wherein the powder coating die is ...

A method for monitoring production of a fluid film, including: activating a dispenser to deliver appropriate material from a storage duct to a metering system for even distribution of a fluid film; allowing the fluid film to pass a sample retrieving roller; measuring the fluid film on the sample retrieving roller using a data reading device to obtain film thickness data; transmitting the data to an analyzer to examine the data against a predetermined reference value; transmitting a comparison result in real time by the analyzer to a production equipment controlling console; controlling the storage duct to dispense material through the material metering system and adjusting the film thickness; repeating the above steps to make a film thickness within the reference range; and maintaining the thickness at the narrowest tolerance deviation, and continuously delivering the film onto a substrate for production. 1. A method for monitoring production of a fluid film , comprising:a) activating a dispenser to deliver an amount of raw material from a storage duct to a metering system and distributing the raw material by the metering system to produce a fluid film;b) allowing the fluid film to pass a sample retrieving roller;c) measuring the fluid film on the sample retrieving roller using a data reading device to obtain a film thickness;d) transmitting the film thickness to an analyzer, and comparing the film thickness with a predetermined reference value and producing a comparison result by the analyzer;e) transmitting the comparison result in real time by the analyzer to a production equipment controlling console;f) adjusting the amount of the raw material by the production equipment controlling console according to the comparison result;g) setting a tolerance deviation, and repeating a)-f) to obtain a fluid film having a film thickness within the tolerance deviation from the predetermined reference value; andh) continuously delivering the fluid film obtained in g) onto a ...

A method of manufacturing a lithium-ion secondary battery electrode sheet disclosed herein includes the step of preparing powder 220 of granulated particles. In this step, the powder ( 220 ) of granulated particles ( 240 ) including active material particles ( 241 ) and a hinder ( 242 ) is prepared. The powder ( 220 ) is deposited on a strip-shaped collector foil ( 201 ) that is being conveyed. Then, the powder ( 220 ) is removed from widthwise center portions ( 202 ) and ( 203 ) of the collector foil ( 201 ), and a squeegee ( 106 ) is brought into contact with the powder ( 220 ) remaining on the opposite sides of the center portions ( 202 ) and ( 203 ) of the collector foil ( 201 ), thus adjusting the thickness of the powder ( 220 ). Subsequently, the powder ( 220 ) remaining on the opposite sides of the center portions ( 202 ) and ( 203 ) of the collector foil ( 201 ) is pressed.
