Abstract: A pneumatic plug gauge has been developed in the context of the invention. This plug gauge comprises a first measuring channel which can be connected to a pressure medium source and opens into a first outlet for the pressure medium, which outlet can be directed to a surface of the workpiece to be tested. According to the invention, this plug gauge is designed to determine the tilt angle between a section on the surface thereof and a region opposite this section on the surface of the workpiece by virtue of the first outlet being arranged at one end of the section and at least one second outlet being provided, which second outlet is arranged at the other end of the section. It has been recognized that the admittedly high precision of pneumatic length measurements can be converted in a particularly advantageous manner to high precision of the angle measurement in this manner. The tilt angle can be measured at least with an accuracy of less than one tenth of a degree.

Abstract: A generally rectangular siding panel having a front and rear faces is provided. The siding panel has at least one protrusion disposed along at least one of the faces, wherein the at least one protrusion provides an air gap between the siding panel and a face of a second siding panel when the siding panels are installed in a siding panel assembly. A generally rectangular siding panel having a front and rear faces is also provider where the siding panel has at least one recess or cut spaced along at least one of the faces, wherein the at least one recess or cut provides an air flow path between the siding panel and a face of a second siding panel when the siding panels are installed in a siding panel assembly.

Abstract: A clip for siding panels installed on a wall of a structure includes a substantially planar nailing face and a seat extending from a bottom edge of the nailing face disposed to receive the bottom edge of an overlapping siding panel. A hook member extends from a top edge of the nailing face and is disposed to hang the clip from a top edge of a siding panel overlapped by the overlapping siding panel. The nailing face is sized to provide a partial overlap of the overlapped siding panel by the overlapping siding panel when the clip is attached to the overlapped siding panel by the hook member and the overlapping siding panel is seated in the seat.

Abstract: A composite part, in particular a vehicle panel such as a car body attachment part, a movable glass cover, or an interior space lining, comprises a foamed plastic layer and an elongated, extruded plastic body. The elongated, extruded plastic body enhances stability of the car body attachment part, is reinforced with fibers, and is embedded in the plastic layer at least in sections.

Abstract: A method of producing a foamed part, in particular a car body attachment part for a motor vehicle, includes the following steps. A foaming tool is provided that includes a tool bottom part and a tool upper part. An outer skin is placed in the tool bottom part and an expandable material is applied. The foaming tool is closed, with at least one portion of the outer skin being located in a gap between the tool bottom part and the tool upper part. After the foaming process, during opening of the foaming tool, the outer skin is trimmed by the foaming tool itself. The invention further relates to a foaming tool for applying such a method.

Abstract: A car body attachment part, when mounted to a motor vehicle, has an inner side comprising a surface portion, and an opposite, visible outer side. A method for producing the car body attachment part includes the following steps. A foaming mold is provided that includes a first tool mold die and a second tool mold die. The inner side of the car body attachment part is associated with the first tool mold die, and the outer side is associated with the second tool mold die. Next, a protective foil is inserted in the first tool mold die, at least in a region of the surface portion. The protective foil is provided with a foam backing so that the inner side in the region of the surface portion is constituted by the protective foil. The protective foil is connected with the foam backing such that the protective foil can be peeled off from the foam backing in a non-destructive manner. The car body attachment part is particularly useful as a roof module mounted to a roof of a motor vehicle.
