摘要:
For the continuous treatment of textile or yarn, the textile or yarn, previously soaked with a solution for treatment, is treated both with wet heat in the form of saturated steam of 105*-170*C in a closed system, and in a multi-purpose apparatus for a continuous wet treatment of the cloth. The apparatus includes a wet expander, a device for soaking cloth with a chemical solution and for squeezing the cloth, a high pressure steamer, a washer and a dryer arranged in sequence, and, in addition, a sealing device is provided at the entrance and outlets from the high pressure steamer so that many varieties of finishing can be performed individually or simultaneously.
摘要:
An apparatus for subjecting a continuous length of moving material to a fluid treatment. The material is initially soaked in a bath of processing fluid while in a substantially tensionless condition. Immediately thereafter, the material is guided through a treatment chamber where it is exposed to a high velocity flow of the same processing fluid.

A method of cleaning the surfaces of guide rolls used in treating and processing cloth comprised of the step of passing a strip of material soaked in a cleaning fluid, such as water, in a continuous path over and in contact with the guide rolls. The method is preferably performed by attaching the strip of material to the cloth being processed and continuously passing it through the guide rolls following the cloth to remove any contamination that might have been accumulated on the rolls during processing. In the passage over the rolls, which are preferably reversed during the cleaning operation, the strip of material is squeezed against the rolls and the cleaning fluid assists in the removal of contaminants as the cloth wipes the roll clean.

A unidirectionally reinforced resin structure is manufactured by an apparatus which comprises a melt resin bath in which a melt resin is stored and into which a long fiber bundle passes, and a plurality of opening pins disposed in the melt resin bath. The long fiber bundle is impregnated with the melt resin and opened by the opening pins during the passing in the melt resin bath. The opening pins are arranged in a perpendicular direction with respect to the melt resin bath and the opening pins are composed of at least two groups in the perpendicular direction so as to open at least two long fiber bundles.

An installation for pickling rolled metal strip in order to remove oxides formed thereon. The strip is fed horizontally through an acid solution bath over a series of deflecting rollers rotating about axes perpendicular to the feed direction of the strip and defining, within a single vessel, outward and return paths comprising at least three superposed sections, and walls dividing the vessel into at least two superposed treatment cells of a height which is low enough for the treatment liquid to be driven along by the feeding of the strip by pumping action.

A method and apparatus for impregnating a fibrous base material with a varnish liquid, wherein the so-impregnated base material is substantially air free. A base material is passed under the surface of and through a supply of low-viscosity liquid such as to impregnate the base material with the low-viscosity liquid and displace air from the base material so as to provide a substantially air-free base material. The air-free base material is passed through an entrance for and into a syphon. An inert gas is supplied to the syphon so as to maintain an inert gas atmosphere therein sufficient to maintain the air-free condition of the base material. The air-free base material is then passed through an exit of the syphon and under the surface of and through a supply of varnish liquid sufficiently to displace the low-viscosity liquid from the air-free base material and impregnate the air-free base material with the varnish liquid.

An automatically operated wire intake device is proposed for a wire enameling machine. In this machine the wire that is to be enameled is wound a number of times around roller blocks that stand at some distance from one another. The wire runs through the processing stations of the wire enameling machine a number of times by rotating around these roller blocks. With regards to the wire intake device, a displaceable slide block is positioned on a rotating transfer bar onto which the end of the wire is fastened, and which a pilot carries. Upon each rotation of the transfer bar this pilot comes into contact with a point arrangement which displaces the slide block by one "stage" to the side at each rotation, which displacement corresponds to the spacing of neighboring guide channels on the roller blocks.

In continuous hot dipping of metal strip, the tension of the strip at pre-treatment furnaces and that at air-wiping nozzles are isolated and made independent of each other. For this purpose bridle rolls driven by motors are disposed downstream of the pre-treatment furnaces. The tension at the former is maintained at a lower value, while the tension at the latter is maintained at a higher value. The bridle rolls are mounted in bearings which are covered by seal boxes in which an inert gas is enclosed so as to prevent the intrusion of atmospheric air into the furnaces.
