Abstract
The invention relates to a tensioning/relaxing element that comprises a base (3), at least one rotating shaft (4) mounted on said base, a mobile part (2) and a lashing device (1). Between said base (3) and the at least one shaft (4) at least one nonpositive and positive element (5, 6) is provided that tightly encloses the shaft (4). The first nonpositive and positive element (5), configured as a tensioning element, is firmly linked on the one side (5a) with a part (2) that is mobile vis-a-vis the base (3) and can be actuated on the other side (5b), with a variable and continuous pretension, via a first actuator (11), while the second nonpositive and positive element (6), configured as a relaxing element, is firmly linked on the one side (6a) with the base (3) and can be actuated on the other side (6b), with a variable and continuous pretension, via a second actuator (11'). The invention is characterized in that the tension force or relaxing force can be continuously modified during the tensioning or relaxing process.
