Frequently Asked Questions

ContiAct® is WELSCH INDUSTRIAL’s proprietary technology for continuous high-compaction extrusion of concrete roof tiles. The machines achieve a design speed of 170 tiles per minute (TPM) with a consistent effective output of 140 to 150 TPM for standard tiles. What sets ContiAct® apart is the combination of massive cast-iron construction that absorbs high-frequency vibrations, rolling block link chain pallet drives for micron-level positioning, vacuum-hardened guide rails, and tungsten carbide-armored extrusion heads with chrome-manganese carrier bodies. We also offer specialized ContiAct® machines for complex fittings such as verges, ridges, and hip caps at 25 to 30 TPM, as well as fully customized configurations for unique production requirements.
Yes, WELSCH INDUSTRIAL specializes in the technical overhaul, modernization, and conversion of concrete roof tile production lines across all global brands, with a deep focus on Braas/Redland and Powell Automation systems. Our approach goes beyond simple repair: we elevate existing equipment to modern 2026 performance standards by integrating contemporary mechatronics into proven heavy-duty frames. This includes upgrading pallet drives with zero-backlash power transmission, optimizing extrusion head geometry for improved laminar concrete flow, modernizing cutting tables, and retrofitting wear-critical zones with tungsten carbide protection. We can modernize individual components or deliver complete machine overhauls, extending the productive lifecycle of your capital investment by decades.
The RiLu® spray system is WELSCH INDUSTRIAL’s high-precision coating solution for applying pure acrylic paints to concrete roof tiles at up to 150 TPM. It uses a three-part cabin architecture: a feeding chamber that neutralizes incoming air turbulence, the main spray cabin with specialized sloped-hood geometry, and an exit chamber that captures residual mist for recycling. The polished stainless steel interior is virtually free of ledges or dead zones, while kinetic baffles intercept overspray and direct it into collection basins for reuse. Our 8th generation RiLu® hybrid filter with rotating vibration technology and optional oxygen barrier ensures clog-free filtration over multiple shifts without maintenance interruption.
