Latest Patents

Bruno Granella holds a patent for a method and apparatus for repairing a junction pipe connection to a main. This innovative solution involves a cutter head that is led into the junction pipe and operates primarily with its front face. This design eliminates the need to locate junction pipes in a replaced sewer pipe, which is a common challenge in traditional methods. The cutter head is attached to a flexible shaft, and a feeding device supplies the cutter head during the cutting process. The fastening mechanism centers the device within the pipe being worked on, ensuring precision and effectiveness. The cutter head features an eccentric head that rotates around the center axis of the pipe, along with a cutter wheel that moves in a circular orbit within the pipe. The fastening mechanism consists of three radially adjustable supporting elements and a hydraulic piston-cylinder unit that presses these elements against the inner wall of the pipe. Once the supporting elements are secured, the cutter head is advanced by the feeding device to perform the cutting operation.
