A braking handle (1) for simultaneous braking and guidance of a material in the form of a web being unrolled from a roll (3) comprises two semi-circular cross-section shanks (6, 7) articulated to each other, one end of which is intended to be inserted into a tubular core (2) of a roll (3) of a web material. By squeezing together the portions (9, 10) of the shanks outside of the tubular core, the portions (11, 12) located inside the core will be pressed outwards towards the walls of the core and exert friction against the walls, so that the rotation of the core is braked. The articulated joint (8) between the shanks is made of a semi-rigid material, and one of the shanks is provided with lugs (13) pointing towards the other shank and arranged near the articulated joint. <IMAGE> |
