COPRA ® wire rolling software

speedy verification of the generated tool rolls by COPRA ® FEA RF wire rolling. The software is powerful enough to analyse the entire process in 20 to 30 minutes, so the results of any modifications are available within a very short time. An FEA simulation allows different kinds of investigation direct onscreen, in other words without prototyping and machine set ups. COPRA ® RF wire rolling solutions from data M can significantly increase efficiency in the construction of flexible pipes to convey oil and gas. The powerful simulation tools in particular allow early pinpointing of problem areas.

enormous pressure at depths of more than 1,000m. The pressure armour presents a challenge in the construction of flexible conveying pipes. This is produced by means of a winding process from a Z-shaped profile. The starting material for this profile is solid round steel, which first has to be roll formed. Processing material up to 32mm in diameter, roll forming it into a Z-profile, calls for high-performance tools – and an experienced designer. COPRA ® RF wire rolling software is a highly efficient means of support, for instance, by automatically configuring individual roll forming stations based on the starting and end cross-section of the desired profile. An essential element of roll forming solutions from data M is simple and specified with RAL colour system or with Munsell colour model. A comparison of the measurement with these systems is possible. This data will be stored in a database and serves as reference for productions with the same colour requirement. For the classification in RAL or Munsell colours choose ‘best fit scan’ and you will get the code of the colour shade, that is the most similar to the measured colour. In mode ‘scan with dE’, the measured colour is only accepted within a given tolerance interval around the reference colour. Using the ‘teach-in’ function, new colours can be added to the database e n a b l i n g

SIEBE Colour Match (SCM) The difference of colours between two cables can be safety relevant. For controlling purposes, visual inspection with colour cards is used to check the acceptance limit of the specified colours. Visual assessments are subject to subjective impression arising from factors such as illumination, angle of vision and colour sensitivity of the observer.

customers own specification or other colour reference systems. The minimal visual width of stripes is approx. 0.5mm. Cable diameter can be 1-10mm (optional bigger sizes with extended optics). The inline version can be integrated into a control system via ethernet without having its own display. Provided with an optional touch screen the device can also be operated stand-alone. An extended version is designed for operation in the quality control or laboratory with mechanics to ensure inspection of short samples. The usage of SCM is not only inline production control. Harnessing the adherence of defined colour values can also be controlled. The database with all relevant product colours can easily be copied as a file from one device to another. This ensures a colour compliance regarding production of same cables in different facilities.

SIEBE Colour Match (SCM) is an automatic system to get objective, reproducible and comparable results. An own white light source avoids measurement errors with inappropriate illuminants. Cable colours are often
