Bartell Machinery has successfully designed and manufactured one of the largest Tensile Armouring Machines currently serving the Flexible Pipe Industry. The basic function of the Tensile Armouring Machine is to apply a layer of round or rectangular steel strip onto the flexible pipe being produced. The angle, speed and size of strip that is applied are determined by the flexible pipe specification. Tensile Armouring Machines are Rigid Stranders, meaning that the bobbins are always in the same relative position to the machine center line.
Two (2) machine cage sections are supplied to work in tandem. Each cage applies a layer opposite to the other and is supported by a rear bearing and front support disc. The rear bearing is designed to withstand the static and dynamic load of each cage along with the axial load provided by the wire tension. During machine operation, a pneumatic braking system is automatically adjusted as the bobbins unwind, compensating for the changing bobbin diameter and ensuring constant tension in the wire.
