Abstract: An asphalt sealant material is heated within an insulated box-like container supported by a front caster wheel and a pair of thin disk-like steel side wheels. A push-type handle bar projects rearwardly and upwardly from the container which has an inner bottom wall sloping downwardly to a side discharge tube. A burner tube extends through a surrounding heater tube located within the lower portion of the container, and a heat exchange oil is confined within the annular space defined between the tubes. A propane fuel tank is supported by a platform projecting rearwardly from the container and is connected by a flexible hose to a nozzle located at the front of the burner tube. The rear of the burner tube connects with a vertical exhaust pipe, and the rear of the heater tube connects with an oil fill tube. The sealant discharge tube receives a valve tube rotatable by a control rod extending from the handle bar, and another control rod raises and lowers a squeegee member supported for vertical movement behind a bottom outlet within the discharge tube.

Abstract: A system for two-sided coating of a running paper web. The device comprises an application device for spreading the coating material over both sides of the web running through a first nip formed by a rotating counter roll and a levelling member.According to the invention, the device includes an auxiliary roll, which is, in the direction of progress of the web, fitted at a certain distance from the first nip and which, together with the counter roll, forms a second nip for the web which has followed along with the said roll over the distance. The diameter of the auxiliary roll is substantially smaller than the diameter of the counter roll, and the face of the auxiliary roll is substantially harder than that of the counter roll. By means of the invention, the risk of damaging the coating at the side of the web facing the roll can be reduced by the web being detached from the second nip formed between the rolls.

Abstract: The disclosure concerns a coating device for coating a web which travels over a counter-roller. Upstream of a doctor blade for spreading the coating composition is a coating composition application chamber that includes a resilient tongue e.g. a leaf spring, which extends downstream toward the doctor blade and defines a hydrodynamic pressure slot between the tongue and the web. A pressure space for the coating composition is defined between the downstream end of the tongue and the doctor blade. The tongue is oriented to gradually narrow the height of the hydrodynamic pressure slot between the tongue and the web, and the tongue is resilient or resilently supported for this purpose. An additional retention wall helps close off the pressure space. The pressure space helps avoid air inclusions in the coating composition and creates a quiescent zone upstream of the doctor blade enabling uniform application of the coating.
Abstract translation: 本公开涉及用于涂覆在反向辊上行进的幅材的涂布装置。 用于铺展涂料组合物的刮刀的上游是涂料组合物施加室，其包括弹性舌，例如， 叶片弹簧，其朝向刮刀的下游延伸并且在舌部和腹板之间限定流体动力学压力槽。 用于涂料组合物的压力空间限定在舌头的下游端和刮刀之间。 舌头被定向成逐渐缩小舌头和腹板之间的流体动力压力槽的高度，并且为此目的，舌头是弹性的或弹性支撑的。 附加的固定墙有助于关闭压力空间。 压力空间有助于避免涂料组合物中的空气夹杂物，并在刮刀上游产生静止区域，从而均匀地涂覆涂层。

Abstract: A method of producing coated printing paper by the use of a blade coater. A flexible blade is pressed against a paper web carried by a backing roll, by a support member disposed on the opposite side of the blade so that the blade is bent to a specific curve. The bent blade serves to remove the excess coating applied to the paper web, with improved results. The dwell time that the coating is in contact with the paper before the excess is removed by the blade is kept to a very short period.

Abstract: Two side coaters and methods of coating paper on both sides are disclosed in which a web of paper to be coated is moved in a generally upward direction in partially wrapped relation to a coating roll, so that one side of the web is in contact with and supported by the roll. This one side of the web is coated by a first coating material which is applied by the coating roll. This coating material is applied to the coating roll by an applicator roll, either directly in which a puddle is formed between the applicator roll and the coating roll, or through transfer from a pair of metering rolls in which the coating puddle is formed between the metering rolls. A second coating, which may be the same as or different from the first coating, is applied by a non-contacting jet fountain coater to an area on the opposite exposed side of the web just ahead of or including the area which is in wrapped relation to the coating roll, and the excess coating is blade doctored, employing the coating roll as a back-up roll for the doctor blade. The .[.blade.]. .Iadd.web .Iaddend.side moves upwardly in view of the operator and is turned for subsequent drying or the like with the blade side up. There are also disclosed arrangements by which the lead-in and lead-out angles of the web may be controlled for the purpose of controlling the angle of contact and degree of wrap of the web with the coating roll. The method further contemplates conventional blade doctoring, bent-blade doctoring, and zero-angle blade doctoring.

Abstract: A device for the regulation of the wet application weight of coated webs, the web being supported on its uncoated side by a roll. The device has a stationary, inherently rigid wiping device with a concavely curved long entrance flank so that between web surface and wiping device a sickle-shaped entrance gap is formed. The radius of curvature of the entrance flank of the wiping device is equal to or only slightly greater or smaller than that of the support roll. In order to avoid wear and tear at the edge of the wiping device additional wear elements are provided at the wiping device.

Abstract: A web coating method and apparatus includes a web scraping mechanism arranged after a coating section, the scraper being in the form of a wire bar. The scraping efficacy of the device is improved by forming the wire bar from small gauge wire wound upon a circular or polygonal rod, where the radius of curvature of the wire is 2 mm or less. If desired, the wire bar may be rotated relative to the web as scraping is effected.

Abstract: An edge dam assembly for an applicator for applying a film of coating material on a moving web of paper carried through an application zone, is characterized by a seal element at each side end of the zone. To prevent leakage of coating liquid past the seal element, air is introduced through the element and into the side end of the zone adjacent to the element. The air forms an air barrier pocket at the side end of the zone, which is void of coating liquid, whereby coating liquid is maintained in the zone inwardly of the seal elements.
