摘要： A web to be coated travels over a deflecting roll and underneath a slot nozzle from which a curtain of a coating material falls. A suction box open toward the roll and web has upstream and downstream ends and extends full axial length of the roll. An upstream seal on the upstream side of the box is juxtaposed with the web, extends the full axial length of the roll, and has upstream and downstream edges extending transverse to the web-travel direction. A similar downstream seal is provided on the downstream side of the box juxtaposed with the web. The downstream-seal downstream edge is spaced upstream in the direction from where the curtain falls on the web. Air is withdrawn from the box between the seals to suctionally strip a boundary layer of air from the web between the seals.

摘要： A coating system for a web traveling in a web-travel direction has a slot nozzle from which a curtain of a coating material falls on the traveling web and a pair of guide elements flanking the slot nozzle and having confronting and vertical inner faces engaging and defining edges of the curtain. Respective aspiration elements fixed at lower ends of the guide elements have inner faces vertically aligned with and forming vertical continuations of the inner faces of the respective guide elements, and each formed with a vertical and inwardly open aspiration groove and with a transversely extending vacuum passage open into the respective groove. Respective floors on the aspiration elements downwardly close the respective aspiration grooves and are each formed with a sharp inwardly directed edge closely spacedly juxtaposed with the web. Excess coating material is aspirated from the curtain through the vacuum passages.

摘要： The aim of the invention is to coat running material webs (1). According to prior art, the coating material is applied to the material web (1) by means of curtain coaters. Said coating material is discharged from a slit nozzle (2) and passes through a free-falling curtain (3). The edges of the curtain (3) are separated by means of separating elements (9, 10) before the fall into the material web (1) for adjusting the coating width. According to the invention, a smaller curtain is produced on each edge by means of a first outer separating element (10). Said curtain is adjusted to the desired coating width by means of a second, inner separating element (9). In a preferred embodiment, an inner separating element (9) is used which contains a vertical channel in the interior thereof. Said channel is open on the separating edge. A water supply (24) flows into said channel.

摘要： The invention relates to a method and device for reducing the volume or pressure of a fluid which is driven through an opening (3, 17) by moving surfaces. According to said method, the opening (3, 17) is divided in at least two flow channels (5, 6, 14) by means of one or more flexible separation members (4). Each separation member (4) is attached at its rear end relatively to the direction of displacement of said surfaces, and its front finishing end extends inside said opening (3, 17). The inventive method can be advantageously implemented during production and further transformation of strip-shaped materials (paper, cardboard strips, plastic material sheets) for bringing the strip which moves on an element (cylinder, roll, rigid guiding element, winding reel) into close contact with said element.

摘要： Draw rollers for striplike materials (especially paper or cardboard strips, plastic or metal foils), having a sheath (1) that can rotate around a fixed inner component, whereby said sheath is provided with air holes along the entire surface thereof, are already known per se. A vacuum chamber (8) is arranged in the winding area of the strip. Said vacuum chamber (8) can be subjected to an underpressure. According to the invention, another vacuum chamber (8) is arranged inside the sheath (1) in the running direction of said strip (2) directly in front of the vacuum chamber (8), whereby the underpressure in the second vacuum chamber is greater than the underpressure in the first vacuum chamber (8) and is independent thereof. The upstream second vacuum chamber (8) enables the separating layer of air adhering to the strip (2) to be suctioned in a targeted manner, whereby the contact surface of the strip (2)/roller remains large enough to transmit high drawing forces.

摘要： Known devices for contactlessly guiding or treating continuous lines of material (1) have one chamber (2). A supply device (3) for a gaseous fluid is connected to said chamber (2), which has a gas-permeable wall (4). The outer surface (5) of said wall (4) is embodied as a guide surface for the line (1). According to the invention, the gas-permeable wall (4) is produced from a porous, metal-containing material with open pores which have an average diameter of less than 500 &mgr;m, preferably less than 100 &mgr;m, especially less than 20 &mgr;m. The porous material used for the guiding surface enables the line (1) to glide on a fluid pad of less than 1 mm. The losses of fluid on the surfaces not covered by the line (1) are very low.
