This invention pertains to a process for testing windscreen wiper blade end caps. In the course of this process, first, the end caps are pushed toward the windscreen wiper blade from both sides, during the installation phase, via slide-in plate (6) until the fitting tab on the bottom of each end cap slides into the receptacle on the end of the corresponding flexor, thus capping off the wiper blades and fixing them in place. The process is characterised in that it establishes, during the installation process, whether the end caps have been adequately fitted and secured, by attempting - during the return phase, at an appropriate pre-set force controlled by a force-regulating unit (3) - to pull the installed caps out of position using a test assembly head that includes, among other things, a slide-in plate (6), noting that if the end caps remain in place undamaged, then they have been adequately fitted and secured. If, however, they have been improperly secured, then the end caps can be removed by the test assembly head (4) during the return phase via the slide-in plate (6) and, once the end caps have been taken away and the windscreen wiper blade inspected, further testing may take place. The test device is characterised in that it has a securing bridge (1), force-regulating unit (3), test assembly head (4), and accessory test apparatus with axis of rotation (5), such that either the securing bridge (1) is affixed with a securing element (7) to the slide-in plate (6) in a manner that permits an immovable joint, or the securing bridge (1) and slide-in plate (6) are fashioned as a single structural unit. It also has an accident-preventing cover (2), mounted onto the securing bridge (1) with at least one cover-securing element (8). The force- regulating unit (3) has a threaded force adjustment stem (31), a tension-producing element (32), and a set nut (33) and locking nut (34) that fit over the threaded force adjustment stem. |
