Abstract: 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.

Abstract: A process for making a noise absorber carpet including a fabric layer and a resinous backing layer, the process including providing an uncured resinous backing layer within a mold having perforation pins, heating the backing layer to activate the resin, providing a fabric layer, pressing the fabric layer into the backing layer while maintaining the heating process to the backing layer, and providing a cooling medium to cool the mold to fix and cure the perforations within the backing layer thereby forming noise absorber perforations in the resinous backing layer.

Abstract: A system for controlling a shield plate in a helmet includes a shield plate 4 pivotally supported on a cap body 2, and a control lever 52 capable of being turned between a neutral position N in which the full closing of the cap body is permitted, and a slightly opening position A in which the shield plate in the fully closed position is pushed up and opened at a very small opening degree. In this system, the control lever 52 has a locking position permitting the control lever to turn from the neutral position in a direction opposite from the slightly opening position A. The shield plate has an abutment projection 61 formed on its inner surface, while the control lever 52 has a locking claw 52d adapted to be put into abutment against a front surface of the abutment projection 61 to inhibit the opening of the shield plate 4 upon turning the control lever 52 to a locking position B when the shield plate is in the fully closed position.

Abstract: In a full-face helmet including a chin-covering portion provided on a cap body to define a space for breathing of a user, the chin-covering portion includes a lower end edge which is formed to be directed upwards in a backward direction on wearing position of the cap body, and bulges formed at left and right outer surfaces thereof to be continuous to the lower end edge. Therefore, travel wind is passed on outer surfaces of the bulges to traverse the lower end edge, thereby generating a negative pressure or vacuum at a lower portion of the chin-covering portion to draw out the user's breath in the breathing space to below the chin-covering portion. Thus, the fogging of an inner surface of a shield plate is prevented without deteriorating the strength of the chin-covering portion.
