Abstract: A window seal testing machine for seals of the type used in powered automotive windows, the testing machine comprising an adjustable frame simulating a portion of a powered automotive window, the frame being adapted to receive one or more sets of window seals and a piece of window glass therein to simulate the sealing relationship between the seals and window glass in an actual automotive window. The testing machine further includes a drive mechanism for repetitively cycling the window glass through the frame and seals to simulate actual window operation over hundreds or thousands of cycles. The entire machine is preferably self-contained and portable, and the frame is further adjustable to be adapted to test different sets of seals and types of window glass.

Abstract: A crimp on flange tool of the type used to crimp door seals to vehicle door frames, comprising a handheld tool connected by a flexible drive coupling to a remote, separate drive unit whose weight is not added to the weight of the handheld tool when used by a human operator. The invention further includes a novel operator handle arrangement for the handheld tool, in which a handle is on-axis with the crimping rollers. Another aspect of the invention is a novel roller arrangement comprising two sets of parallel rollers, with a first set being spaced more widely to function as guide rollers and a second, downstream set being spaced more narrowly to crimp a seal fed to them by the guide rollers.
