Abstract: An oven for baking a thermally curable binder in a mat of mineral fibers, including plural compartments through which the mat of fibers passes successively, the mat being compressed and transported through the compartments by gas-permeable upper conveyors and lower conveyors, each compartment having a length along a direction of movement of the mat and including a mechanism introducing a hot air flow, located either below or above the fiber mat, and a mechanism extracting the air after having passed through the mat, respectively arranged either above or below the opposite face of the mat, so that the binder is progressively brought to a temperature higher than its curing temperature. In one compartment the mechanism introducing hot air includes air inlets that open partly on openings formed on a first lateral side of the compartment and partly on openings formed on the opposite lateral side of the compartment.

Abstract: A dryer for an electrode substrate of a rechargeable battery according to an exemplary embodiment of the present invention includes: a drying oven for drying an electrode substrate by feeding the electrode substrate to an inlet and discharging it through an outlet; fixed guide rolls provided at a distance from each other between the inlet and the outlet to guide the electrode substrate; lifting guide rolls ascended or descended at one side of the respective fixed guide rolls to guide the moving electrode substrate; driving rolls disposed to correspond to locations of the lifting guide rolls; and a shuttle moving toward the outlet from the inlet.

Abstract: An oxidation furnace for the oxidative treatment of fibers, in particular for producing carbon fibers, with a housing which is gas-tight, apart from passage areas for the carbon fibers, and a process chamber located in the interior of the housing. Hot air can be blown into the process chamber by at least one air inlet device. Deflecting rollers flanking the process chamber guide the fibers arranged side by side in the form of a carpet through the process chamber in a serpentine manner, wherein each fiber carpet spans a plane between opposite deflecting rollers. The air inlet device allows hot to be diverted to the side of the deflecting rollers facing away from the process chamber such that hot air flows over the respective deflecting roller and the fibers before it enters the process chamber.

Abstract: A photographic processor includes a circular processing drum and a circular drying cylinder. A transfer arm is utilized to transfer processed photographic media from the circular processing drum to the circular drying cylinder. The circular drying cylinder includes an outer housing and a diffuser member having slots provided therein. The slots extend in a spaced manner from an entrance to an exit of the drying cylinder so as maximize the drying of film in the drying cylinder.

Abstract: A moving-web slack reducing system including a deformable tension roller, such as a brush-type tension roller having an outer surface defined by the ends of a plurality of bristles. The slack reducing system may be deployed in a preheater assembly for a machine for manufacturing corrugated board. The bristles of the deformable tension roller allow the outer surface of the tension roller to deflect both radially and in the cross-machine direction without binding to the paper web. The bristles may also deflect variably across the tension roller in the cross-machine direction. Thus, the deflection of the bristles adjusts automatically and virtually instantaneously to changes in the tension of the paper web to compensate for variations in tension across the web in the cross-machine direction. This allows the brush-type tension roller to take the slack out of the paper web without having to rapidly and precisely adjust any actuators.

Abstract: A double backer for curing the web bonding adhesive and drying the corrugated paperboard web utilizes a web holddown apparatus for maintaining the web in intimate drying contact with the lower heating units which does not require the use of a driven holddown belt. The holddown is provided instead by a series of parallel, flexible, closely spaced strips suspended above the web in the heating section and extending in the direction of web travel. The length of the holddown strips in contact with the web may be selectively varied.

The holddown is provided instead by a series of parallel, flexible, closely spaced strips suspended above the web in the heating section and extending in the direction of web travel. Supplemental holddown force may be provided by banks of spring fingers supported above and in contact with the holddown strips on a transverse support rod which may be rotated to vary the amount of supplemental holddown force. Alternately, the holddown strips may comprise continuous cables in which one run of the cables rests upon the moving web to provide the web holddown and a second run includes high friction cable portions which are movable into driving contact with the upper surface of the web to pull it through the heating section, as for initial web thread up.

Abstract: A dryer system for drying a coating applied to a substrate includes a thermally conductive roll having a length and a peripheral surface for supporting the substrate, and a plurality of energy emitters disposed within the conductive roll along the length of the conductive roll. The plurality of energy emitters are controlled to selectively emit energy along the length of the conductive roll. The conductive roll is at least partially surrounded by at least one convection unit. The convection unit includes a blower assembly, a heater assembly and a vacuum passageway. The blower assembly includes an inlet and directs a current of air towards the substrate. The heater assembly heats the air being directed towards the substrate. The vacuum passageway extends between the substrate and the inlet of the blower assembly for returning the heated air to the blower assembly once the air has impinged upon the substrate.

Abstract: A fabric-finishing machine comprises a tank in which there is a series of drums driven in the same direction and forming an entrainment path extending from the front portion of the tank to the rear portion in a rectilinear direction. The drums entrain a single piece of fabric spread out or a plurality of pieces gathered into ropes. At least one nozzle is associated with each drum, for supplying an air-jet which presses the fabric, spread out or in ropes, onto the respective cylinder so as to achieve conditions of adhesion such that dry, moist or wet fabrics can be entrained.

Abstract: A processing apparatus comprises at least one wet processing station followed by a dryer in which wet sheet material comes into contact with heated drying air. Sheet material is fed over a static support member which supports the sheet material during drying. A drying unit is positioned opposite to and extending across the support member in a transverse direction, thereby to define a drying space between the support member and the drying unit. Drying air is fed to the drying unit to pass out through a drying air exit into the drying space. The support member includes a plurality of openings to allow drying air to pass therethrough, to ensure that the air flow is substantially the same whether a sheet of photographic material is positioned on the support member or not, while minimising the generation of turbulence.
