Method for horizontally splitting cured mineral wool web
A recently granted patent (Publication Number: US11982030B2) discloses a method and apparatus for horizontally splitting a cured mineral wool web. The method involves providing a cured mineral wool web on a conveyor, longitudinally dividing it into at least two sub-webs, lifting a sub-web by lifting a section of the conveyor, and horizontally cutting the lifted sub-web. The cutting is performed by a band saw with an endless saw band having a horizontal lower active cutting path and an upper return path perpendicular to the conveyor's direction of travel. Simultaneous cutting can be performed on the sub-webs, with the band saws running in opposite directions towards the exterior side edge of the initial web.
The apparatus for horizontally splitting the cured mineral wool web includes a conveyor for advancing the web, at least one dividing device for dividing the web into sub-webs, lifting mechanisms for lifting each sub-web at different locations on the conveyor, and horizontal cutting devices for cutting the sub-webs while lifted. The conveyor is a roller conveyor with sub-lines of rollers corresponding to each sub-web, and the cutting device is provided above each lifting section. The band saws can run in opposite directions towards the exterior side edge of the initial web, ensuring efficient cutting of the sub-webs. Overall, the method and apparatus described in the patent aim to streamline the process of splitting cured mineral wool webs horizontally, improving efficiency and productivity in the manufacturing process.
