  • Process for cleaning vehicle parts, in particular glass panes of vehicles
    Patent number: 5116424
    Abstract: The present invention pertains to a process and a device for cleaning parts, in particular glass panes (2) of vehicles to prepare them for subsequent treatment processes, such as application of adhesive, etc. The cleaning device (1) comprises a wiping element in the form of a cleaning band (10) which is moved relative to the part (2) to be treated. The cleaning band is guided in a loop (12) between two rolls (13 and 14) and is brought into contact with the part (2) to be treated, while the cleaning band (10) is wound off section by section and cyclically between or during the cleaning processes. To do so, an additional loop (44) is formed in the area of the loop (12) and fresh band material is wound off of the reserve roll (13). The loop (44) is subsequently eliminated and the used band material is fed to the used-material roll (14).
