Tensioning device and method for tensioning a workpiece

Abstract:

A tensioning device for tensioning a workpiece includes a main body having a chamber, a fluid inlet providing fluid communication between a fluid source and the chamber, a puller member supported in the main body and configured to engage the workpiece, and a piston positioned in the chamber and coupled to the puller member. Movement of the piston moves the puller member along a piston axis in at least a first direction. The tensioning device further includes a sensor coupled to the piston and operative to measure a displacement of the piston and/or the puller member in a direction parallel to the piston axis. The sensor generates a signal indicative of the displacement.
