Abstract:
A noise absorber carpet comprised of a fabric layer portion and a resinous backing layer portion is provided. The fabric layer portion and the resinous backing layer portion are heat bonded with a press into the noise absorber carpet, and the press includes perforation pins and a cooling medium. The resinous backing layer portion is provided with noise absorbing perforations formed by contact with the perforation pins of the press and cooled by the cooling medium. The perforations having been cooled by the cooling medium with the press simultaneously with the bonding of the resinous backing layer portion with the fabric layer portion and the cooling of the press by the cooling medium, thereby providing for instant curing and fixation of the shape of the perforations.
