Abstract
A differential shaft for a strip-producing machine comprises a differential shaft mainly made up of a shaft core, a securing plug disposed at one end of the shaft core, a multiple of rolling tubes and partition rings each alternatively positioned with the other and sleeve joined in a sequence onto the shaft core thereof, and a fixing plug clamping tight of the partition rings and the rolling tubes thereof from the other end of the shaft core. The partition rings are stably located onto the shaft core via a pair of position pins engaged with a pair of stepwise retaining recesses of the shaft core with a ring gap A formed between the partition rings and the shaft core to reduce the friction thereof when the rolling tubes proceed with the strip production, effectively prolonging their lifespan in use. Moreover, pressed tight by said fixing plug, the partition rings can transversely move at the stepwise retaining recesses via pivot pieces of the position pins thereof, evenly distributing the clamping force onto each rolling tube for more smooth and efficient rolling movement thereof.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
