摘要

The device has a metal strap (4) with a rectilinear portion (41) connected to a movable support unit and to a semi-circular portion (42). The portion (42) is applied against a roller (5) connected to a fixed support unit, and extended by a rectilinear portion (43). A stress generator (70) has reciprocating finger (71) acting on portions (41, 43) to deform the strap between fixed support units (10) to arrange the device in two zones.
