Braking device, heald frame with such a braking device and loom with such a frame

Abstract

This braking device for the assembly of a column (1G) and a crossbar (2H) of a loom heald frame comprises a pressure screw (3), which lower face has at least one tooth and a blade (4) arranged under head of screw (3) and having at least one tooth adapted to be elastically returned towards the head of the screw (3) in a position where at least one tooth of the screw (3) and at least one tooth (447) of the blade (4) are brought into contact in the event of the rotation of the screw (3) in. The loosening direction (D). The blade (4) and the screw (3) have lateral dimensions smaller than the thickness of the crossbar and the blade (4) has at least one surface forming an obstacle to the rotation of the blade (4) around the screw (3).
