Abstract:
The present invention is directed to construction tools. The present invention includes tools used for applying mastic or mud to a work surface, for example, a flat box mastic applicator tool, blade assembly, and/or blade adjustment system, that have many improvements too numerous to mention all in the Abstract. The flat box mastic applicator may include unique walls. The blade assembly may have a non-uniform cross section, e.g., a blade holder with thinner areas and/or material removed at various locations along its lateral length. The blade holder may have a larger size outer end(s) to withstand bending or braking. The blade holder may have and arched shape, ribs or bumps for holding a blade more firmly, and a ridge or bump at its outer edge to act as a dam. The blade adjustment system may include symmetrical pins or posts and a tapered leaf spring. See further improvements herein.
Abstract:
An application apparatus includes a nozzle device (20) injecting a damping material from a nozzle hole (20a) to a vehicle body, an articulated robot (21) moving the nozzle device (20) relative to the vehicle body, a supply section including a supply pump (22), and a supply passage (27), and continuously driving the supply pump (22) to continuously supply the damping material from the supply pump (22) to the supply passage (27) in a substantially uniform amount, a return passage (33) branched from the supply passage (27) and returning the damping material to the supply pump (22), and a gun (32) and a return valve (34) switching a supply destination of the damping material between the nozzle hole (20a) and the return passage (33) based on information on applying the damping material to the vehicle body.
Abstract:
The invention relates to a spin coater for a device for the generative production of an object, having a support (1) which can be connected to the device in a rotable manner about a rotational axis (z); and a coating element (2) which is coupled to the support (1) and which is suitable for applying or leveling a powder layer on a plane in the device while the support (1) is rotating, said plane running perpendicularly to the rotational axis (z); wherein the coating element (2) substantially maintains its orientation during the rotational movement of the support (1) within a specified rotational range; and the coating element (2) substantially does not move in a longitudinal direction of the coating element (2) during the rotational movement of the support (1) within a specified rotational range.

Abstract:
A rod-bed assembly has a holder (30) and an insert (20) removably and insertably supported in a groove (31) of the holder (30), the rod-bed assembly being for a rod (10) rotatably supported in a recess (21) on a front side of the insert (20). Longitudinal bending of the holder (30) in a cross-direction is under 0.5%, advantageously under 0.35%, of the longitudinal distance between two profiling loading points of the holder (30).
Abstract:
A fastening structure which fixes a doctor blade to a holder is provided, which includes a cylindrical portion provided on one surface of the holder with which a doctor blade is overlapped, a through hole having an inner diameter larger than an outer diameter of the cylindrical portion and penetrating through the doctor blade. In the fastening structure, while the cylindrical portion is inserted through the through hole with a gap between an outer circumference of the cylindrical portion and an inner circumference of the through hole, an end portion of the cylindrical portion is pressed to be expanded in an outer circumferential direction and then bent towards the doctor blade, to thereby fix the doctor blade to the holder by supporting it between the end portion and the one surface of the holder.
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 blade mounting apparatus for a blade in a coater secures essentially the entire blade length. The coater provides a cross profile adjustment of a suspension flow. The blade mounting apparatus includes an adjustable thrust element engaging the blade along a line-shaped thrust contact area extending in a direction parallel to the longitudinal edge of the blade. The position of the contact area of the adjustable thrust element is variably adjustable, with local limitation, for providing cross profile adjustment.
Abstract:
A doctor for applying material, having a pressing part (doctor body) bending elasticly in the longitudinal direction and corresponding to the application width and a row of segments for pressing the pressing part, the segments (20) are connected in link-like manner by web or holding parts (203, 29, 39, 4, 40 to 48) to a unit-forming pressing device (2) pressing at least one pressing part (3, 30, 31, 32, 36), and the segments (20) being held independently to the pressing part (3, 30, 31, 32, 36).
Abstract:
A device for unilaterally clamping an elastic doctor blade into a cutting beam. The tension of the blade is varied in relation to a web of material that is to be coated and that runs over a mating roll. The doctor blade rests against the web of material along a doctor line parallel to the cutting beam. The blade is rigidly supported in its midsection along a line of support that is in fixed position with respect to the web of material parallel to the doctor line. The lower edge of the doctor blade can be displaced with respect to the plane of the doctor line and the line of support. The doctor blade is positioned in a longitudinal recess in the cutting beam. The doctor blade is clamped into the longitudinal recess against an elastic resistance in the cutting beam by means of an elastic pressure-medium hose. The lower edge of the doctor blade is guided toward the line of support when displaced out of the plane of the doctor line and the line of support. The geometric relations in the vicinity of the doctor line accordingly remain as unvaried as possible even when the tension on the doctor blade is varied.
