Abstract
The process is in particular intended for the manufacture of tinplate and comprises cutting a strip in the direction transverse to the direction of rolling of a reel of steel sheet, subjecting said strip to a drawing action by compression while bending the strip, and examining possible cracking on the surface of the drawn strip. This process is carried out in an apparatus which comprises a frame 1 supporting means 2 for pulling a steel strip and a head 4 for effecting a drawing action by compression while bending the strip. The head is connected to the frame and the steel strip 3 is passed through the head under the action of the pulling means 2.
