RMVT by Bauce, a leading manufacturer of leather pressing and drying machines, declares an important evolution in sammying machines, a crucial stage in leather processing, during which the material is pressed by felt cylinders to remove excess water and prepare the leather for the next stages of tanning.
We met with Luca Bauce at the Trissino headquarters in a plant that is working at a solid pace: despite the general market slowdown, and he explained the qualities of the machine. “Robustness,”he stressed, “is the main characteristic of RMVT. The machinery features a double-sided system that protects the inside movements. It has a support structure that uses two “shoulders,” or robust lateral pillars, to support and shield the internal mechanical components. This configuration offers greater stability and strength than single-shoulder systems because it better distributes the load and reduces the risk of bending or deformation of the skin during machine operation. It also allows movements to be kept safe from external contamination, contributing to the durability and reliability of the machine over time, an essential feature in industrial applications where plants are subject to continuous operations, and for a high number of hours. An additional quality lets the RMVT stand out from conventional sammying machines, namely the ability to automatically align the cylinder with the blades, in a preventive action from misalignment. When turned on, the machine realigns itself while also considering any blade wear that might occur with regular use. Every day it always positions itself at the same point, with the utmost precision, as if just calibrated, ensuring excellent results on middles, splits and full skins, consistent quality of work and greater reliability of the machine over time.
RMTV has a hydraulic power pack dedicated entirely to modulating felt pressure, a crucial element in ensuring uniform, precise and targeted leather processing. The control unit is the beating heart of the hydraulic system, adapting the pressure exerted on the felts as needed-an especially important feature when processing leathers of different thicknesses and textures, as each type of leather requires a specific pressure to achieve a uniform, high- quality finish without the risk of damaging.
Despite its considerable weight (about 17 tons), the innovative machine stands out on the market for its energy efficiency. In fact, every motorized component of the machine is fully electrically powered, from the motors responsible for the movements of the rubber roller for the felt cylinder pressure, to those for the movement of the rubber cylinder for the blade cylinder action, as well as for the closing and opening operations of the machine. A smart system that meets the increasing attention of the client to sustainability, reducing emissions and improving energy efficiency. Due to its electric nature, then, it has fewer components than conventional machines. This results into less chance of breakdowns and easier detection and troubleshooting, thanks also to the support of tele-service, which allows each machine to be monitored and serviced remotely, even from a different facility.”
Another crucial aspect of the RMVT success of Bauce relates to fully automated lubrication designed in-house with proprietary technologies, including an air-powered grease pump. The felt washing system is similarly automated, with dedicated hoses and nozzles, and integrated with a metering pump to distribute the washing detergent efficiently.
“The Bauce RMVT,” concludes Luca Bauce, “represents a step forward in electronics for tannery machines, which are now more efficient, more precise and easier to maintain. Technological advances that set new standards of excellence in the industry and give the machine a prominent place in Industry 5.0.”
