Abstract: A method and apparatus for rejection of defective mineral fibre slabs in a continuous production process of mineral fibre slabs.

Abstract: The present invention concerns a method and an apparatus for rejection of defective mineral fibre slabs in a continuous production process of mineral fibre slabs, said method comprising the steps of providing a continuous flow of rows of a predetermined number of mineral fibre slabs on a first conveyor with a first direction of travel; detecting each of the slabs in a row for defects; redirecting one or more defective slabs onto a second conveyor for further processing and transferring the remaining non-defective slabs in a row to a third conveyor, downstream of the first conveyor and having a third direction of travel; or if no defective slabs are detected in the row, the entire row is continued onto a fourth conveyor and onwards to a fifth conveyor both being downstream of the first conveyor and has the same direction of travel as the third conveyor; receiving the non-complete row of non-defective slabs from the third conveyor on a buffer table, and assembling a complete row from non-defective slabs receive
