Abstract: A hydraulic section-stretching machine, having a cylinder and piston co-operating with a stretching grip, a longitudinally movable but arrestable counter-grip having clamping jaws operative perpendicularly to the section-stretching axis, the counter-grip being provided with two C-shaped apertures in the same plane, perpendicular to one another, one facing the stretching grip to accommodate the section to be stretched, and the other facing the stretched material to be transported, and a severing means close to the clamping jaws, acting in a vertical plane perpendicular to the stretching axis.
