LAMINAR BLOCK AND METHOD OF AND APPARATUS FOR PRODUCING THE LAMINAR BLOCK ABSTRACT OF THE DISCLOSURE A laminar block useful as an insulating material comprising a laminar body composed of a plurality of lamin- ated sheet-like members, each member being made of the inorganic fibers; at least one first stitching thread parts, each having a first surface thread part extended along an outer surface of a sheet-like member situated at one surface side of the laminar body, a first penetrating thread part extended substantially continuously from one end of the first surface thread part so as to penetrate the laminar body in a direction of a thickness thereof and a second penetrating thread part extended substantially continuously from the other end of the first surface thread part so as to penetrate the laminar body in the direction of the thickness thereof; and at least one second stitching thread parts, each having a second surface thread part extended along an outer surface of a sheet-like member situated at said one or the other surface side of the laminar body, a third penetrating thread part extended substantially continuously from one end of the second surface thread part so as to penetrate the laminar body in the direction of the thickness thereof, and a fourth penetrating thread part extended substantially continuously from the other end of the second surface thread part so as to penetrate the laminar body in the direction of the thick- ness thereof at a portion different from that where the first and second penetrating thread parts of adjacent one first stitching thread part penetrate the laminar body, can be cut into a desired shape or size relatively easily as required and the laminated state of cut pieces formed by the cutting of the laminar block can be maintained with less fear of separation or disintegration.
