Abstract
An apparatus for controlling a warp tensioner of a weaving machine. The apparatus contains a spring member that is in working connection with the warp tensioner and a control system that has a container communicating via a 2/2 way valve with the spring member in order to vary the spring stiffness of the spring member and the position of the warp tensioner from a terminal at the side where the weaver stands by increasing and decreasing the effective volume of the spring member.
