Abstract: A system and method for measuring tube movement through a tube altering machine includes a first sensor device for detecting a rotational movement of the tube caused by the tube altering machine as the tube passes therethrough. A second sensor device detects a linear movement of the tube caused by the tube altering machine as the tube passes therethrough. These precise measurements are achieved without marking or damaging the tube material and can be compared to anticipated measurements to determine if machine settings should be altered.

Abstract: Incoming tubes are turned and fed into a pilger mill by use of a single gearbox using a rotating dual track drive system. The dual track system holds the incoming tube while tube reducing (metal tube forming) occurs by the pilger tooling. When the pilger tooling is free of the incoming tube product, the dual track drive moves the tube into the pilger tooling by feeding an incremental amount of tube product. The dual track drive also indexes the incoming tube at the correct time and at a pre-determined amount. Additionally, the gearbox sub-assembly bumps the tube at a pre-determined time while the tube is free from the tooling.
