CONCRETE PRODUCTS & CAST STONE120 CPI %u2013 Concrete Plant International %u2013 5 | 2025 www.cpi-worldwide.comWith a new Masa Cuboter, Spanish paver manufacturer Cleannox %u2013 Prefabricados de La Jara S.L. has taken a decisive step towards more efficient and reliable packaging of its end products. The modern solution replaces the previous stacking system to create the paver packages, eliminates central bottlenecks in the production process and impresses with precise motion control, high energy efficiency and a well-thought-out safety concept %u2013 precisely tailored to the requirements on site.In summer 2019, Cleannox extensively modernised its production facility in Villanueva de la Jara, Spain. At that time, Masa supplied a fully automatic L 9.1 block and paver making machine including production board feed, hydraulic desk, multi-colour device and the corresponding safety installation (see also CPi 03/2020). The new ring plant was supplied by a local machine manufacturer, while the existing dosing and mixing plant continues to be used.The Masa L 9.1 has proven to be extremely efficient and reliable in Cleannox's production, much to the satisfaction of owner Alfredo Cebri%u00e1n. His company has experienced continuous growth, mainly due to the increasing demand for its products. However, this success has also brought new operational challenges. In particular, a significant bottleneck was emerging in the area of paver layer stacking, a central step in the production process.The cubing plant used so far for stacking the paver layers had served its purpose for a certain time, but was showing increasing signs of ageing. Its limited capacity and the increasing number of breakdowns led to noticeable losses in efficiency, unplanned downtime and delivery delays.Against this backdrop and after carefully examining various systems available on the market, Alfredo Cebri%u00e1n decided to reorient his technology in this section. Based on his positive experience with the Masa block and paver making machine, he once again chose Masa. The new solution was to not only work more efficiently, but also offer greater process reliability and reduce maintenance costs.Investing in efficiency: The Masa Cuboter as a new cubing solutionThe central element of the comprehensive replacement investment is the Masa Cuboter, a high-performance cubing machine supplemented by modern safety technology and a completely new control system. After the old plant was dismantled by the customer, Masa delivered the fully servo-electric Cuboter. This is already designed in the standard version for product layers with lifting weights of up to 700 kg and product heights of up to 500 mm.With the commissioning of the Masa Cuboter, Cleannox now benefits from a wide range of powerful features and functions that significantly increase efficiency, flexibility and process reliability in automated cubing:Automated precision at Cleannox in SpainMasa GmbH, 56626 Andernach, Germany Put to the test: the previous cubing plant
