ABSTRACT:
An anchor on a tendon twisted of a number of steel wires has at least one double-cone widening, the biggest diameter of which is at least three times bigger than the diameter of the unfanned tendon part. The method for producing the anchor comprises seizing the tendon on two spaced apart places and bulging it between these places to form a widening. On the frame of the device for carrying out the above method there are provided two means for seizing the tendon on two places spaced apart whereby one of the means is actuated to exert an axial load on the tendon.
