Feeding system

A feeding system comprising:

• a feeding apparatus for feeding an elongate, wire-shaped or tubular workpiece to a forming machine, wherein the feeding apparatus has a receiving device for receiving a workpiece supply in the form of a coil and a straightening system (400) which is downstream of the receiving device and which has two adjustable rolling/straightening apparatuses which are connected one behind the other and which have differently orientated straightening planes for straightening the workpiece before introduction into the forming machine;
• a measurement unit for measuring residual curvatures on straightened wire-shaped or tubular straightening material which has passed through the straightening system of the feeding apparatus, and for establishing measurement data which represent a residual curvature of the straightened straightening material;
• characterized in that a cutting device for separating rod-shaped portions of a predeterminable length from the straightening material which has passed through the straightening system;
• the measurement unit has a measurement apparatus for receiving a rod-shaped portion, which is separated from the straightening material, of the straightening material which has passed through the straightening system in a measurement position;
• and
• the measurement unit is configured for a measurement which is specific to the straightening plane and which allows association of the curvature portions which represent the measurement data with the different straightening planes of the rolling/straightening apparatuses.
