Abstract (en)
Heald frame for weaving looms comprising two sidepieces (F) and two crossbars (H) mutually fixed at right angles by coupling joints, each crossbar (H) consisting of a metal extruded profile which comprises an appendix (C), at the longitudinal inner edge of the crossbar (H), to which a heald-bearing plate (S) is fixed, the hooked ends of a plurality of healds (L) being hooked with a play (G)to said heald-bearing plate (S). The heald frame further comprises a braking device of the heald (L) free movement by inertia allowed by said play (G), said braking device consisting of a deformable profile (1) fixed to the longitudinal inner edge of each of said crossbars (H) in such a position as to interfere with said free movement of the healds (L) and having a predetermined stiffness in order to allow a deformation of the deformable profile (1), upon contacting the ends of the moving healds (L). Said predetermined stiffness is low enough to allow said free movement of the healds (L) up to the limit stop contact of the healds (L) against one of said heald-bearing plates (S), and at the same time is high enough to lower the speed of said free movement of the healds (L).
