Abstract:
The invention relates to a method for applying an at least two-component, curable and viscous material in the form of a material strand (12) or a series of material points to a workpiece, an application process (20) starting at an application start time (22) and ending at an application end time (24), and the workpiece with the material applied thereon being destined for further processing (32) which starts at a processing start time (30) and ends at a processing end time (34). According to the invention, the mixing ratio (38) of the components is varied by a control device depending on predetermined and/or measured parameters (22, 24, 30, 34) during the application process (20) in such a way that the material applied to the workpiece can be processed at any point of the material strand (12) or at any material point at the processing starting time (30).
Abstract:
A system of pointillist painting comprises an automated 3-D positioning system disposed proximate a painting surface, a colorant dispenser coupled to the gantry structure and having a dispensing tip in fluid communication with a colorant chamber, the gantry structure operable to move the colorant dispensing tip to a specified position of the painting surface, where the colorant dispenser is operable to apply a specified amount of a colorant to the painting surface and creating a dot having a two-dimensional coverage and three-dimensional profile at the specified position.
Abstract:
A liquid dispenser gun (14) for mixing first and second liquid components of a two-component mixture (1 1 ) and dispensing the two- component mixture (1 1 ) includes a gun body (78), a mixing manifold (82), and a nozzle plate (84). The gun body (78) includes a gun body fluid passage (94) in fluid communication with gun body inlets (38, 50, 56) and the mixing manifold (82). The gun body fluid passage (94) is a groove in a bottom surface (79) of the gun body (78) having a generally non-linear shape such that the second component has a generally laminar flow through the gun body fluid passage (94) while a flushing component may be introduced in the gun body fluid passage (94) in a manner to produce turbulence in the flushing component.

Abstract:
The invention relates to a machine for filling the edge joints of insulating glass panes with a semiliquid to paste-like sealing compound. Said sealing compound consists of a main constituent and a secondary constituent which are different in chemical terms and in terms of their viscosity. According to the invention, the edge joints are filled with the sealing compound by means of two pumps (3, 6) which convey the two constituents from two reservoirs (1, 2) into separate intermediate storage parts (5, 8) and by means of separate, synchronously driven volumetric feed metering pumps (14, 19). Said metering pumps (14, 19) pump the constituents in a predetermined composition into a mixer (16) and then on to a nozzle (17). The nozzle (17) and the mixer (16) belong to one sub-assembly which is mounted as a whole on a frame of the machine in such a way that it can move. A gear pump (14) driven by a servomotor serves as a metering pump for the main constituent together with a piston pump (19) which serves as a metering pump for the secondary constituent. The piston (20) of said piston pump (19) is driven by a second servomotor (23) and the two metering pumps are preferably part of the mobile sub-assembly.
Abstract:
Method and device to pressure balance hoses at supply of two different components with substantially the same pressure to an extrusion head (13), where the flow of the second component is substantially below the flow of the first component, e.g. at thermosetting plastic extrusion. The first hose (10) for supply of the first component during at least a substantial part of the path to the extrusion head (13) is arranged to enclose the second hose (11) for supply of the second component.
