1. A calendar for satinizing fibrous webs directly with only two roller pairs arranged in a plane above each other in vertical alignment, comprising: a first metallic satinizing roll, having a relatively hard rough surface for satinizing; a first backup roll in first nip defining relationship with only said first metallic satinizing roll, having a resilient smooth surface comprising a synthetic material formed by polymerization of one or more materials; a second metallic satinizing roll; having a relatively hard rough surface for satinizing; a second backup roll in second nip defining relationship with only said second metallic satinizing roll, having a resilient smooth surface comprising a synthetic material formed by polymerization of one or more materials, and fibrous web support means for continued feeding of said web first through said first nip in one direction of entry, said first and second metallic satinizing rollers having uppermost and lowermost locations remote from each other and said first and second backup rollers directly adjoining each other in location intermediate said first and second metallic satinizing rolls with looping angle amounting to 180 degree around one backup roll resulting in web exit in direction substantially opposite to direction of entry and alternately for continued feeding of said web in just the opposite way.
摘要:
A mantle-radiation recuperator with a cylindrical mantle and a distributing chamber, in which the cylindrical mantle conveys the fluid to be heated up and is passed around by flue gases, and in which a recuperator mantle is suspended in a chimney which mantle is connected to supports the outer ends of which are adapted to be rested on the masonry of the chimney or a part connected thereto.
摘要:
A metallic recuperator structure comprising one or more recuperators each comprising an annular chamber defined by an inner cylinder and an outer cylinder surrounding the inner cylinder, a heat absorbing medium being forcibly drawn through the annular chamber while the heating medium passes through the inner cylinder.
摘要:
A high temperature steaming device for steaming webs of textile material with tubular steam distributors which are arranged in the lower section of a steaming chamber and which supply superheated steam to the interior of the steaming chamber. These steam distributors, which have discharge bores arranged in the longitudinal direction thereof and adjacent to each other, are formed by pipes adapted to receive steam which is superheated by being passed along heating coils directly within the steaming chamber.
摘要:
A sealing system for sealing the inlet and outlet slots of treatment containers, especially for widths of textile goods, which includes two sealing beads which form a portion of two inflatable hoses closed at their ends and normally held in cylindrical rims or housing members which are arranged adjacent and parallel to each other and at their adjacent portions are provided with slotted sections bridged by the sealing beads. The sealing beads are respectively surrounded by flexible foils of wear-resistant material, which foils are adapted to be detachably clamped between the cylindrical rims and the pertaining hoses.
摘要:
A device especially for impregnating and dyeing wide textile webs in a continuous manner, which includes a vacuum device, at least one roller and a liquor receiving container, which when being viewed in the direction of the movement of the textile web to be treated, is located behind said container, said vacuum device comprising a hood extending approximately over the length of said roller and being equipped with a rim-shaped structure along its edge into which is placed an elastic endless sealing strip adapted to be pressed against said roller, the lower section of the hood being immersible into the liquor container.
摘要:
A sealing means for a container which permits the entrance or exit of a web of material to be treated inside the container. A cylindrical roll is rotatably mounted in the opening of the container and an endless sealing strip of resilient material is pressed against the roll. The sealing strip has two straight portions, each arranged parallel to the axis of the roll. The sealing strip also has two circular portions near each end of the roll which join the ends of the straight portions. The web material is passed between the sealing strip and the surface of the roll.
摘要:
A sealing means which includes a main roller having a portion of its cylindrical area positioned adjacent to an aperture in a tank which holds a fluid (either liquid or vapor) which is to be applied to a web of material as it passes through the tank and over the main roller. An endless elastic sealing strip is positioned on the main roller and surrounds the aperture, providing a fluid seal. The sealing strip is held in position by a cylindrical channel which is secured to the tank. Additional rollers may be used to enter the material into the tank and reverse its direction.
摘要:
A sealing means for a container which permits the entrance or exit of a web of material to be treated inside the container. Three cylindrical rolls are rotatably mounted in series in the opening of the container and three endless sealing strips of resilient material are pressed against the three rollers. The sealing strips each have two straight portions, each arranged parallel to the axis of the roll. Each sealing strip also has two circular portions near each end of its roll which join the ends of the straight portions. The web material is passed between the sealing strips and the surface of each of the rolls.
