Abstract:
An outer periphery coating method of honeycomb structure has coating steps where the honeycomb structure including a ring-like bulge portion is rotated; a coating member is brought into contact with a side surface of the honeycomb structure by pressing a side edge portion of a spatula via a rubber sheet, the coating member including the plate-like spatula in which a specific cut portion is formed in the one side edge portion and the side edge portion provided with the cut portion is an inclined surface inclined on a coating surface side, and the rubber sheet in which a cut is formed so that an end surface of the end portion is parallel to a back surface of the spatula when the end portion is bent along the side edge portion of the spatula; and a slurry coating material is supplied to the side surface of the honeycomb structure.
Abstract:
A device for applying a free-flowing medium to a continuously conveyed web, wherein the medium can be transferred to the web by a continuously rotating transfer (gravure) roll. An application head is provided in order to transfer the free-flowing medium to the circumference of the gravure roll. The application head includes a chamber which is open toward the circumference of the gravure roll and has an inlet and an outlet for the medium to be applied. The front outer face, in the direction of rotation, of the chamber is delimited by a front doctor blade and the rear outer face, in the direction of rotation, is delimited by a rear doctor blade. Both doctor blades are seated against the circumference of the gravure roll. The front doctor blade can be pressed against the circumference of the gravure roll by a pressing body with an adjustable pressing force.
Abstract:
The invention relates to a doctor blade for the surface treatment of fibrous nonwoven webs, including a main body and a coating arranged on the surface of the main body, wherein the coating covers at least the part of the surface of the main body on which the doctor blade is provided for contact with the fibrous nonwoven web, and wherein the porosity of the coating is less on the first surface adjoining the main body than on the surface arranged opposite thereof.
Abstract:
A new doctor blade by which resin finishing can be stably applied to such a thin cloth having a weight 120 g/m2 or less is provided. The doctor blade has a lower portion bent to form an inclined surface so as to supply a resin composition on the inclined surface of the blade and to coat the resin composition on a cloth moving from the blade tip side to the blade body side, the lower portion 3 of the blade 1 in a width of 2-12 cm being bent to make an angle of 110-160 degrees to the blade body (upper portion 4). The tip portion 5 of the lower portion 3 of the blade 1 may be bent backward in a width of 3-10 mm at an angle of 50-150 degrees to the lower portion 3 of the blade.

Abstract:
A metering device which, for the purpose of forming an adhesive medium sump (21), is associated with an application roller (16), having at least one film applicator (36), a pull-off edge (50) of said film applicator (36) extending in a metering gap (28) formed between the application roller (16) and the metering device (14), is characterized in that an adhesive medium dispenser (51) is provided, in the metering gap (28), on a film applicator (36) side situated opposite the adhesive medium sump (21). A metering device as described above is characterized in that the dispenser (51) is aligned so as to lead away from the applicator roller (16).
Abstract:
A pre-honed doctor blade (1) with a lamella profile (2), produced by means of a grinding wheel (3), wherein the lamella (2) has a curved profile (shaped as an arc of a circle or as an arc of an ellipse) and the manufacturing grooves (4) produced by the grinding wheel (3) on the lamella (2) are not parallel to the edge of the doctor blade (1).A method of producing said doctor blade (1) is also described, comprising at least the steps of:positioning above the band a grinding wheel (3) with its axis of rotation not at right angles to the edge of the doctor blade (1);setting the grinding wheel (3) in rotation;moving the band beneath the grinding wheel (3) parallel to its edge.The grinding wheel 3 can be a cylindrical grinding wheel or a conical grinding wheel; during the processing, the edge of the doctor blade (1) can be maintained on the vertical drawn from the centre of the grinding wheel (3) or offset with respect to said vertical.
Abstract:
There is disclosed a method for the manufacture of coating or doctoring blades, wherein an elastomeric wear-resistant material at the blade tip is provided in a continuous process. During the manufacturing, the thickness of the applied elastomeric material is determined by winding the blade (containing the applied polymer composition) into a coil before the applied composition is fully cured. Successive turns of the coil are separated by a distance which is smaller than the initial thickness of the applied composition, such that the only partly cured composition is deformed by adjacent turns of the coil into the desired thickness and/or shape.
Abstract:
Equipment for changing a blade (43) in a coating device (51) changes several blades (43) arranged in a band (43). The equipment includes reels (11, 40) connected to the ends of the blade holder (45), for holding the reeled unused and used band (43); transfer devices (13, 20) for moving the band (43) in connection with the blade holder (45), and lifting devices (17) for lifting the band (43) up and lowering it into the blade holder (45). Indentations (44) at least the length of the hollow shaft (52) are arranged at regular intervals on the band (43), and are arranged to permit the blade (43) to be lowered into the blade holder (45).
Abstract:
A treatment equipment, which is intended to be installed in connection with a moving surface. The treatment equipment includes a frame and a blade holder formed from composite material as a single piece and connected to the frame. In addition, a blade is fitted to the blade holder, the bevelled edge belonging to which is arranged to be brought into contact with the moving surface by moving the blade holder. In the blade holder, there is also a separate backing blade, which is fitted at one edge into the blade holder, the other edge extending closer than the blade holder to the said bevelled edge.
Abstract:
A method for the surface treatment of a doctor element including a steel alloy, in particular austenitic steel, for coating devices. The doctor element is subjected to a gas plasma-assisted treatment, the gas plasma containing nitrogen and carbon compounds and at least one noble gas, preferably argon. During the treatment, foreign metal foreign ions, in particular titanium and molybdenum, are implanted directly into the steel surface of the doctor element.
