A fluid application device (10), strand engagement device (30), and method of controlling the same are provided. The fluid application device (10) includes an applicator head (16) and a nozzle assembly (22). The nozzle assembly (22) includes a guide slot (34) configured to receive a strand of material and an orifice configured to discharge a first fluid on to the strand. The strand engagement device (30) is secured to the applicator head (16) and includes an actuating assembly and an engagement arm connected to the actuating assembly. The engagement arm is configured to engage the strand and move between a first position and a second position in response to actuation of the actuating assembly. The method of controlling the strand engagement device includes receiving an input signal including content, determining the content of the input signal and operating the strand engagement device in response to, and based on the content of, the input signal.
Abstract:
The invention relates to a roll coating process for applying a coating layer on a non-continuous sheet, comprising the steps of 1) applying a liquid coating composition to the top surface of the sheet by passing the sheet horizontally between an applicator roll and a backing roll; 2) forwarding the coated sheet with a coated sheet forwarder; wherein forwarding is interrupted after passing the applicator roll while maintaining a meniscus of liquid coating composition between stopped sheet and rotating applicator roll, and forwarding is restarted when the meniscus has disappeared. With this process it is possible to make sheets coated with an optical coating like an anti-reflective coating, which sheets show markedly smaller and less visible edge defects, especially at the trailing edge. The invention also relates to a roll coating apparatus suitable for operating the process of the invention, which apparatus comprises at least an applicator roll, a backing roll, a coated sheet forwarder, and control means to operate the sheet forwarder depending on the position of a sheet in the apparatus.
Abstract:
The present invention concerns a method of applying a coating (11, 12) to a glass sleeve (3) with an inner surface (5) and an outer surface (7), which glass sleeve (3) is realized as a part of a solar-receiver tube (1). Thereby, the coating (11, 2) is solely applied to one of the said surfaces (5, 7) of the glass sleeve (3). The invention also concerns such glass sleeve (3) a method of fixing such glass sleeve (3) in an interior of a coating tank, such coating tank (35) and a fixing arrangement (28) for fixing such glass sleeve (3) in an interior of a coating tank (35).
Abstract:
An applying apparatus (1) for applying a liquid agent to a coated part of an electric wire (100) includes a liquid agent tank (10) and a porous member (20). The liquid agent tank accommodates a liquid agent therein, and includes a pressurization mechanism (11) pressurizing an inside of the liquid agent tank. The porous member comes in contact with a coated part of the electric wire with holding the liquid agent delivered from the liquid agent tank, so as to apply the liquid agent to the coated part. The liquid agent tank delivers the liquid agent to the porous member by pressurization of the pressurization mechanism.
Abstract:
The invention relates to a device (100) for applying a material strand to an object, which material strand is intended for the production of an element for electromagnetic shielding. The device (100) comprises a first cylinder (120), which is arranged to accommodate a dispensable first material, a second cylinder (122), which is arranged to accommodate a dispensable second material, and a piston (130, 132) in respectively the first (120) and the second cylinder (122), which pistons (130, 132) are arranged movably in the respective cylinder (120, 122). The device (100) further comprises a drive member having a piston unit (190) for unison displacement of the pistons (130, 132) in order to achieve respectively a first flow of the first material from the first cylinder (120) and a second flow of the second material from the second cylinder (122), a merging unit for merging the first and the second flow into a merged flow in which the first flow flows around the outside of the second flow, and a dispensing nozzle (118) for dispensing the merged flow onto the object in order to achieve the material strand. The invention also relates to a method for applying the material strand.
Abstract:
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur gezielten Beschichtung von Kathetern. Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrichtung zu entwickeln, welche eine kontinuierliche und gleichmäßige Beschichtung von Kathetern und Ballonkathetern ermöglichen. Verwendet werden dabei handelsübliche Katheter ohne eine notwendige spezielle Vorbehandlung. Das erfindungsgemäße Verfahren zur Beschichtung von Kathetern oder Ballonkathetern ist dadurch gekennzeichnet, a. dass der Katheter mit einer Vorrichtung, welche eine abgemessene Menge einer Beschichtungslösung enthält, mit einem gleichbleibenden Abstand vollständig oder annähernd Teil derart radial umschlossen wird, b. dass die Beschichtungslösung den Raum zwischen dem Katheter und der Vorrichtung vollständig ausfüllt und so den Katheter auf einem axialen Teilabschnitt vollständig radial umhüllt, c. dass die Vorrichtung in axialer Richtung mehrfach über die Oberfläche des Katheters bewegt wird und d. dass zwischen den einzelnen Beschichtungsvorgängen eine gezielte teilweise Trocknung der aufgetragenen Beschichtungslösung erfolgt.
Abstract:
Strand positional guide implements, for use in connection with hot melt adhesive strand coating applicator assemblies, comprise a plurality of V-shaped strand guide slots wherein the apex portions are oriented outwardly away from the hot melt adhesive material dispensing nozzles. Accordingly, an enlarged air space is effectively defined between the plurality of elongated strands and its respective hot melt adhesive material dispensing nozzle such that the plurality of elongated strands are not adversely affected by the heat or thermal radiation generated by or emanating from the hot melt adhesive material dispensing nozzles thereof.
