ABSTRACT:
The invention relates to a safety edge for horizontally pivoted rolling gates actuated by a motor unit. It consists of a profile (11) made of rubber or other soft flexible material and having a base (14) for its application to a rolling date, and of two electrical conductors (15, 16) extending longitudinally into the soft profile, parallel and normally separate from one another. The conductors move closer in the presence of a deforming thrust on said profile, to come into contact and enable an electrical circuit to send a signal for stopping the rolling gate motor unit.
