📋 Tender Overview
When measuring press felts manually there is often a risk of jamming tripping and slipping. At some positions the employee is additionally exposed to enormous heat and the constant danger of a felt break also represents a significant permanent safety risk. Yet the measurement of felts is an important component in the papermaking process. The automated measurement with Voiths ProTect NG Next Generation therefore offers an excellent alternative to determine the important felt data without risk.The ProTect system consists of an autonomous carriage and one or more fixed rails traverses. The user waits on the runway during the measurement and thus no longer remains in the hazardous area. A carriage can be used in different paper machines. It does not matter how wide the machines are and whether the carriage has to run to the left or to the right.The new generation of the ProTect NG carriage also offers programmable measuring cycles self-diagnosis and remote service access. Furthermore the carriage speed can be reduced to the point where 3D mapping travel is possible. The traverses can be installed in almost any position even those that are difficult to access. No water electricity or compressed air connection is required at the actual measuring points as the ProTect NG carriage is a self-supplier. Only the charging station needs a 110220V power connection - and in the best case a water connection to fill the tank.Optimized diagnostic options with the new ProTect NGThe new ProTect NG continues the global success of ProTect and offers several new benefits for customers. With the experience of much more than 200 installed positions ProTect has become the standard for semi-automatic press felt measurements. ProTect NG is the consistent further development of the original ProTect system with improvements in all areas. In addition to weight reduction and optimized serviceability functionality has been improved above all explains Torben Beckmann Global Product Manager at Voith Paper.Besides the ability to program individual macros for more customized measurements ProTect NG has a number of pre-programmed procedures including detailed edge analysis automatic CD and MD measurements and variable speed measurements. ProTect NG offers the service expert the flexibility for individual measurements while making standard measurements as easy as possible.Torben Beckmann Global Product Manager at Voith PaperProTect NG provides an optimized diagnostic option which can be combined with all available measuring instruments. The integrated display shows the most important carriage parameters as well as the pre-installed measuring run programs. The intuitive operability provides even inexperienced operators with quick access to the various analysis options. ProTect NG also convinces with its further reduced weight which is achieved by using carbon and 3D-printed parts. The lower weight is important for more comfortable handling combined with increased safety for the staff.The 3D felt mapping enables precise measurements of the felt parameters for optimization and fault elimination. Depending on the measuring device used water permeability moisture tension and temperature can be measured.3D diagnosis of the press felts in CMDIn combination with suitable felt measuring devices the very low speed of the ProTect NG enables three-dimensional scanning of felt surface temperatures moisture and water permeability profiles of the press felts. Depending on the machine width a 3D scan can take several minutes during which time the service technician now no longer needs to be in the dangerous area. Voith offers a tensiometer specially developed for felt tension measurements that saves the values on a USB stick during the measurement. After the measurement the measured values are read out in the PC.
