Abstract: A short dwell coater apparatus is disclosed for coating a web with a coating material, the web moving contiguously with a rotating backing roll. The apparatus includes a housing which is disposed on the opposite side of the web relative to the backing roll. The housing defines a chamber is connected to a pressurized source of coating material. The chamber is exposed to the web such that the web supported by the backing roll is coated with the coating material during passage of the web past the coating chamber. Each of a first and second weir extend in a cross-machine direction such that the coating chamber is bounded by the weirs and the web moving between the weirs. The first and second weirs define respectively first and second overflow gaps. The arrangement is such that during use of the apparatus, when the web moves past the coating chamber, coating material is coated onto the web while excess coating material overflows through the first and second gaps for recirculating through the coating chamber. A resilient blade is disposed downstream relative to the second weir. The blade cooperates with the coating material coated onto the web such that the pressure exerted by the coating material on the blade is less than the pressure of the coating material within the coating chamber, so that mottling and streaking of the resultant web is inhibited while maintaining minimum pressure on the blade.

Abstract: A squeegee device is used for applying materials of varying viscosities, such as coating substances, varnishes and adhesives to an application surface. The squeegee is pressed onto the application surface by a magnetic force. A profile member houses the squeegee and is pivotably supported by a bearing. The bearing allows the squeegee and profile member to be tiltable along an axis that is perpendicular to the longitudinal axis of the squeegee or profile member in order to insure a tilting-free and bending-free adjustment of the squeegee on the application surface.

Abstract: Formed on the doctor element, between a chamber mouth and the paper web respectively the backing roll supporting it, is an application space which relative to the doctor element, that is, on the entrance side of the paper web, is defined by a baffle plate and kept at a pressure which exceeds atmospheric pressure. Between the baffle plate, this application space 2 is subdivided toward the doctor element (coating blade) 1, creating between the end of the vane 2 and the coating blade 1 a gap whose width ranges between 4 mm and 10 mm. This makes it possible to produce a flawless coating application also in the case of very light basis application weights.

Abstract: The invention refers to a method and a device for varying the application amount of a coating agent at the blade coating of a moving material web (24,40,51), preferably a paper web, by corresponding control of the engagement pressure of the coating blade (20,43,50,68) against the web (24,40,51) which exhibits a coating agent surplus. The web is supported by a support, preferably a rotating support roller (25,41), and the blade is along one of its longitudinal sides clamped in a blade holder (21,44,49,69), moreover the blade is initially, with a certain force and thereby in an obtained arcuate shape, brought, with the opposite longitudinal side thereof, into engagement with the web, in a certain given angle between blade tip and web, and with a thereby defined engagement area.A control pressure is exerted onto the major side of the blade when the engagement pressure is to be changed, the attack point of the control pressure on the blade is displaced in the transverse direction of the blade, towards or away from the web. At the same time the size of the control pressure is adjusted. Said displacement and adjustment are done partly to provide the desired blade engagement pressure and partly to mainly maintain the angle between the blade tip and the web.

Abstract: A coater for coating a running paper or cardboard web comprises a coating chamber having one side open against the web and means for filling the coating chamber with pressurized coating substance. The coating chamber is limited in the longitudinal direction of the web by a web entrance wall, and opposite thereof, a back wall in the form of a doctor member for forming a coating layer on the web. The distance between the walls is so short that, at normal web running speed, the web moves from the web entrance wall to the back wall in a time of at the most 0.3 s, preferably at the most 0.03 s. Coating substance is supplied by means of positive pressure to the coating chamber at a position close to the web entrance wall. Close to the web entrance wall the flow of coating substance in the coating chamber is divided into two branches, of which a first branch follows the web in its running direction towards the back wall and a second branch, which is considerably greater than the first branch, flows out from the coating chamber through a slot between the web entrance wall and the web.

Abstract: An apparatus for doctoring a cylindrical rotating surface, comprising a doctor back mounted for rotation about a first axis, and a blade carrier assembly mounted on the doctor back for rotation about a second parallel axis. A doctor blade is removably supported by the blade carrier assembly and is loaded against the rotating surface by a force applied to rotate the doctor back about the first axis. A liquid filled flexible walled tube extends along the second axis between the doctor back and the blade carrier assembly. The blade angle is adjusted by expanding and contracting the liquid filled tube to rotate the blade carrier about the second axis.
