Abstract: A method for determining the curing behavior of an adhesive- or sealant bead, the adhesive- or sealant bead being applied to a workpiece, places multiple test bodies on the adhesive- or sealant bead at different, pre-defined placement times, and deformations of the adhesive- or sealant bead, caused by the test bodies, are measured at a pre-defined end time.

Abstract: A device for applying a viscous material includes an application tube which has a material inlet opening on a first end and a material outlet opening on a second end, which defines an application channel, and which is flexible at least over one portion of its length, and a housing which accommodates the application tube, and which has a material supply connection for the viscous material to the application tube, wherein the application tube is connected to the housing in an initial region coming from the material inlet opening, and is arranged at a distance to the housing in an end region extending to the material outlet opening, and wherein a bearing section of the end region is mounted near to the material outlet opening in a motor-driven eccentric that can rotate about the longitudinal central axis. An adjustment mechanism is provided for adjusting the distance of the bearing section to the longitudinal central axis.

Abstract: An apparatus for conveying viscous material out of a barrel-like container having a container bottom and a container wall that extends upward from the container bottom has a follower plate for closing off the container, which plate is movable in the direction toward the container bottom, lying against the inner surface of the container wall, which surface faces the container interior, and which plate has a dome that extends upward from an underside intended to lie on the viscous material, which dome opens, in the center, into a material exit opening. The apparatus has a pump for conveying the viscous material through the material exit opening. At least one displacement body projects into the dome through the material exit opening and is connected with the pump for displacement of the material situated in the dome and/or air situated in the dome, and at least one closeable venting opening vents the dome.

Abstract: A method applies an at least two-component, curable and viscous material in the form of a material strand or a series of material points to a workpiece, an application process starting at an application start time and ending at an application end time, and the workpiece with the material applied thereon being destined for further processing which starts at a processing start time and ends at a processing end time. The mixing ratio of the components is varied by a control device depending on predetermined and/or measured parameters during the application process in such a way that the material applied to the workpiece can be processed at any point of the material strand or at any material point at the processing starting time.

Abstract: A device for applying a pasty mass having an at least two-component, curable adhesive or sealant includes a housing, a lance, which is accommodated in the housing and can be rotated about a longitudinal housing axis and in the interior of which a material supply channel extends to a lance tip bounding the lance in the axial direction for each component of the adhesive or sealant, and a rotary feed-through for introducing the component of the adhesive or sealant into the respective material supply channel through a jacket of the housing, wherein a closing valve is associated with each material supply channel, which closing valve can close the material supply channel at a valve seat.

Abstract: The invention relates to a method and an arrangement for producing body components (48) being provided with an acoustically-effective silencing material layer (44). The aim of the invention is to enable fully automatic packaging making use of the silencing material layer (44). The silencing material that consists of a plastic material which can be cured in a thermal manner is applied onto a flat surface of a body component in a pasty, moisture-absorbing form as a layer (44), and the exposed side of the silencing material layer is covered with a cover layer (46) that facing the body component flat surface. The over layer consists of moisture-impermeable material. The thus pre-packed body component (48) can be randomly transported, intermediately stored and/or supplied for further processing under exposure to air. Curing of the silencing material (44) is only carried out in a subsequent procedure step, for example in an enameling oven.

Abstract: In the method described, a compound substantially in the form of a paste is fed by means of a pump from a storage container (1) to a metering device (3) which determines the amount of paste to be applied to a workpiece (B). From the metering device, the paste is fed to a spray head (S) where it is mixed with compressed air from a cylinder (4) or other suitable supply and sprayed on to the workpiece (B). The amount of compressed air supplied to the paste for spraying purposes is controlled by means of a control unit (6) in such a way that a strip of substantially constant width is applied to the workpiece (B).
