Resin film coated heat insulating and sound absorbing material, a method and equipment for manufacturing the material

In a process for producing a resin film covered heat insulating/sound absorbing material comprising:

• covering front and rear surfaces and both side surfaces along the longer sides of a plurality of inorganic fiber mats cut to have a predetermined length, with resin films in a state that the mats are placed along the resin films of continuous band-shape with a predetermined spacing between the mats,
• cutting the resin films along a direction of the shorter sides of the inorganic fiber mats at portions between the inorganic fiber mats in a state that the resin films are pressed by a pressing member, and
• bonding mutually front and rear side resin films extending from the shorter sides of the inorganic fiber mats at the same time of the cutting step;
• the process for producing a resin film covered heat insulating/sound absorbing material being characterized in that the resin films are pressed by a pressing member having film setting portions at both ends of its bottom surface, whereby the ear portions of extensions of the resin films at the shorter sides of the inorganic fiber mats are prevented from spreading sideways.

In an apparatus for producing a resin film covered heat insulating/sound absorbing material, comprising two conveyers placed with a space between the conveyers to convey an inorganic fiber mat covered with band-shaped resin films,

• a cutting blade provided between the conveyers so as to be perpendicularly to the conveying line of the conveyers,
• pressing members disposed on both sides of the cutting blade, and
• receiving plates disposed under the respective pressing members,
• wherein the resin films are cut at portions between the inorganic fiber mats by the cutting blade in a state that the films are pressed against the receiving plates by the pressing members to produce a resin film covered heat insulating/sound absorbing material,
• the apparatus being characterized by further comprising a film setting portion provided at each of both ends of the bottom side of the pressing members, for pressing the resin films to prevent the ear portions of the resin films from spreading sideways.
