Abstract

A multiply bonded mineral fibre board may be obtained by longitudinally compressing a fleece and then dividing it into two or more layers (43, 45), subjecting at least one of these layers to thickness compression and then recombining and bonding them, and preventing break-out of the tensioned sub-webs between the compression stage (53, 54) and a bonding stage (25).
