Process and system for making noise absorber carpet and a noise absorber carpet made therefrom
摘要:
A process for making a noise absorber carpet including a fabric layer portion and a resinous backing layer portion including the substantially concurrent steps of continuously feeding a softened resinous backing material from a backing resin feeder onto a backing roll to form a continuous resinous backing sheet thereon, and continuously feeding a heated continuous fabric sheet via a fabric roll onto the backing sheet continuously formed on the backing roll, wherein the backing roll includes spike depressions and perforation pins on its surface, and wherein the fabric roll is located close to the backing roll to press the fabric sheet against the backing sheet as the sheets proceed between the rolls and mold spikes and perforations on the backing sheet, the backing roll being cooled to a temperature range between 10 degrees Celsius and 50 degrees Celsius with a cooling medium to harden said spikes and perforations and provide bonding between the fabric sheet and the backing sheet.
