A method of and apparatus for manufacturing a mineral fiber insulating web by providing an uncured primary nonwoven mineral fiber web treated with binding agent, conveying the primary nonwoven mineral fiber web along a predetermined path of travel, compacting the primary nonwoven mineral fiber web, severing the primary nonwoven mineral fiber web into at least two secondary nonwoven mineral fiber webs, compressing at least one of the secondary nonwoven mineral fiber webs substantially beyond the initial compaction of the primary nonwoven mineral fiber web, positioning the compressed and remaining of the two secondary nonwoven mineral fiber webs into contiguous relationship to each other, and curing the binding agent to adhere the secondary nonwoven mineral fiber webs to each other thereby forming a cured multi-ply mineral fiber web or strip. The method is varied by fan-folding the mineral fiber web after the same has been compressed and thereafter at least partially curing the fan-folded mineral fiber web and proceeding as aforesaid. The apparatus includes opposing pairs of compression rollers or compression belts for compressing the secondary nonwoven mineral fiber web, guides for moving the secondary nonwoven mineral fiber webs out of the plane of the uncured primary nonwoven mineral fiber web, saw for cutting the uncured primary nonwoven mineral fiber web selectively along horizontal or vertical planes, guides for aligning the compressed secondary nonwoven mineral fiber web into contiguous relationship with a remaining secondary nonwoven mineral fiber web, and reinforcement/treatment systems for improving surface characteristics, heat transference, moisture permeability and the like.
