Have one data table, structured similar to this:

Activity Time Manufacturer

9 0 A

8.7 0 B

8.3 1 B

9.2 2 A

....

Fit a Model in JMP with Y = Activity and the following terms: Time, Manufacturer, Time*Manufacturer.

In the report, if Manufacturer is significant, that tells you that the intercept for the time models are different. If the Time*Manufacturer term is significant then that tells you that the time slopes are different. I am guessing this is what is needed. You did however state EQUIVALENCY. If you need EQUIVALENCY, the process is more complicated. I hope this is what you really needed.
