US 5948508 A Resumen
The depth of the roof-ditch channel has so far been typically between 8 and 30 mm in order to allow for insertion of the relatively voluminous prior art constructions of FIGS. 1 and 2, for example. The insert 1 according to the present invention can be used for a broader range of roof-ditch channel depths of from about 2 mm or more and, more preferably, between about 3-30 mm. The roof-ditch channel is typically spot-welded at the junction 13 of the roof panel 11 and the side panel 12, and there are usually several welding points along the longitudinal extension of the roof-ditch channel 10 resulting in an undulating shape of the roof-ditch bottom sometimes also referred to as the pillowing effect. The depth of the roof-ditch channel varies along the lateral extension of the roof-ditch channel mainly because of the step at the junction 13, because of the pillowing effect, and because of the impressions at the spot welding points, resulting in a total variation of, for example, �2 mm from the average depth along the lateral extension and of about �1.5 mm from the average depth along the longitudinal extension of the roof ditch channel.
The material used in the typically protruding outer parts 16 of the body 3 is selected together with the dimensions, in particular with the thickness (vertical extension) and the width (lateral extension) of the outer parts 16 to allow for essentially self-centering and/or friction-fitting mounting of the insert 1 into the depression 2. Friction-fitting preferably reliably secures the insert 1 to the depression 2, in particular without grazing the inner surface of the depression 2 which might result in corrosion problems. It was found by the present inventors that the materials used in the deformable, typically protruding outer parts 16 of the bottom area 7 are preferably selected together with the dimensions of the outer parts 16 to impart a Taber stiffness as measured according to TAPPI (Technical Association of Paper and Pulp Industry) T 489-M-60 using a deformation angle of 15�, of between 5 and 50 g.cm and, more preferably, of between 10 and 40 g.cm to the outer parts 16 of the bottom area 7.
In the next step the insert 1 positioned in the depression 2 is subjected to the painting cycle. The painting cycle preferably is an on-line painting process resulting in painting of the insert 1 and the adjacent surface bordering the depression. The paint may be applied by various techniques such as, for example, dip coating, spray coating, powder coating or electrostatic coating with electrostatic and powder coating being preferred. The temperature-time profile applied during the painting cycle may vary depending mainly on the painting technique and the paint used. In the automotive industry electrostatic coating presently is the dominantly used technology. A typical painting cycle includes two or more painting steps each followed by a drying step at a temperature of between 160-180� C. for about 30 minutes.
The materials useful for preparing the bottom area 7 and, in particular, the outer parts 16 of the bottom area 7 of the body 3 are selected by using the Taber stiffness test in order to evaluate their deformability. The Taber stiffness test was performed according to TAPPI T 489-M60 using a deflection angle of 15�. The stiffness is reported in Taber stiffness units (g.cm).
A roof-ditch channel was simulated by bending two stainless steel sheets (length 100 cm, width 7 cm, thickness 0.8 mm) to provide a trough-shaped depression with an essentially rectangular cross-section when positioned in an overlapping mode as shown, for example, in FIG. 4. The two metal sheets were spot-welded at the junction of the two stainless steel sheets at intervals of 80 mm. The simulated roof ditch channel had a length of about 1 m, a minimum lateral extension as measured at the bottom of the roof-ditch channel of 14�2 mm, and a depth as measured along the spot welded junction of 6�0.5 mm.
A layer of Structural Sealing Tape 5222 commercially available from 3M Company, St. Paul, Minn., U.S.A. having the dimensions 100 cm�8 mm�0.05 mm was placed in the bottom of the roof ditch channel.
An essentially anvil-shaped profile as shown in FIG. 4 having a bottom width of 12.5 mm, a top width of 8 mm, a height of 5 mm, and a length of 100 mm was obtained by extrusion of POCAN 7916, which is commercially available from Bayer AG, Germany. The outer parts 16 of the bottom layer 7 had a thickness of about 250 μm and a width of about 2 mm. The extruded profile was then forced into the simulated roof-ditch channel using hand pressure. The gap formed between the paintable surface and the edges of the simulated roof-ditch channel was 3�1 mm.
The simulated roof-ditch channel with the inserted body was subjected to a first painting step (application of a primer) followed by a first drying step (180� C., 30 min.), and then to a second painting step (finish coating) and a second drying step (180� C., 30 min.).
A simulated roof-ditch channel was prepared according to the method described in Example 1. The simulated roof-ditch channel used in Example 2 had a length of approximately 1 m, a minimum lateral extension as measured at the bottom of the roof-ditch channel of 14�2 mm, and a height as measured along the spot-welded seam of 6�0.5 mm.
A layer of Structural Sealing Tape 5222, commercially available from 3M Company, St. Paul, Minn., U.S.A., having the dimensions 100 cm�12 mm�1 mm was placed on the bottom of the roof-ditch channel.
The body 3 comprising the aluminum strip with the POCAN 7916 strip being adhered to it, was subsequently forced into the simulated roof-ditch channel 10 using hand pressure. The simulated roof-ditch channel with the inserted body 3 was subjected to a first painting step (application of a primer) followed by a first drying step (180� C., 30 min.), followed by a second painting step (finish coating) and a second drying step (180� C., 30 min.).
