A tensioner for the controlled clamping and forward movement of an elongate element, in particular for winding/unwinding a cable, a hose, a pipeline or an umbilical on a reception member. The tensioner comprises at least one frame that carries three guide boxes arranged around a passage axis. This tensioner comprises means for maneuvering these guide boxes, in particular second maneuvering means for the maneuvering in rectilinear, or at least substantially rectilinear, translation of lateral guide boxes, respectively in a direction defining an angle of between 115 and 125, and preferably between 118 and 122, with respect to said central plane. These second maneuvering means comprise at least one rocker element comprising a proximal end mounted so as to pivot on said frame and a distal end mounted so as to pivot on said lateral guide box, respectively about rotation axes extending parallel to said passage axis.

A production system for processing a wire material wound to form a wire reel, in particular reinforcing steel. The production system comprises a receiving device for receiving the wire reel; an unreeling device for removing the wire material on the wire reel; and a processing device for processing the removed wire material. The unreeling device comprises a conveyor surrounding a first deflection roller and a second deflection roller, wherein permanent magnets are arranged on the conveyor and an increased frictional connection can be established between a surface of the wire material and an outer surface of the conveying means by means of the permanent magnets.

A tensioner pad assembly is adapted to be mounted on an endless track of a tensioner to frictionally clamp an elongated product supported and moved by the tensioner. The pad assembly includes a carrier member and a pair of gripping members, which gripping members can with their carrier member mating surfaces be mounted in multiple discrete gripping positions on gripping member mating surfaces of the carrier member. The mating surfaces form interlocking structures adapted to transfer a squeeze force from the carrier member to the gripping members. The interlocking structures provided on the carrier member define the multiple discrete gripping positions. The gripping member mating surfaces extend at an angle relative to each other, such that the multiple discrete gripping positions differ in their distance to the base portion as well as in their distance to the imaginary plane of the carrier member.

A device for towing very long tubular objects comprises a casing and an assembly which can be fixed removably to the casing. The removable assembly comprises: pulling means capable of driving in their movement, by friction, the object in a towing direction, gripping means capable of exerting a load on the pulling means to keep the pulling means and the towed object in continuous contact; the gripping means being driven by a relative movement relative to the towed object in a direction opposite to the towing direction. The casing comprises driving means, connected removably to the pulling means and gripping means and configured to drive in movement the pulling means and the gripping means in a coordinated manner to ensure a continuous and uniform pulling of the object.
