Abstract: A tufted carpet constructed by embedding pile yarns on a primary base fabric, where a ratio at which a surface of the primary base fabric is visible accounts for 5% to 85% as viewed from above the tufted carpet. The primary base fabric is formed by entangling a color fiber, a characteristic fiber, and a low melt fiber on a spunbonded base fabric or a woven base fabric. The color fiber imparts an appearance design to the surface of the primary base fabric; the characteristic fiber has at least one function selected from the group consisting of deodorization, antibacterial, anti-allergen, and anti-mite; and the low melt fiber melts at a lower temperature than melting points of the other color fiber and characteristic fiber, and fixes these fibers on the surface of the primary base fabric by thermocompression-bonding. The resulting carpet exhibits excellent shape stability, economical efficiency, and lightness.

Abstract: In a bending press, the stroke length of a ram member is automatically set based upon conditions such as the angle to be made on a workpiece, the width and configuration of a groove in a lower tool, and the thickness, width and tensile strength of the workpiece. There is also an input device into which the bending conditions are set and a computer for calculating the stroke length of the ram member which is then automatically adjusted. A device for detecting deflections occurring in an overhead beam in the bending press is connected to the computer to compensate for the stroke lengths of the ram member. The press accurately and easily bends sheet-like workpieces into various shapes including those cylindrical and semicircular in cross section.

Abstract: This invention relates to a method and apparatus for adjusting a stroke length of a ram for a press. The stroke length of the ram is adjusted with respect to a base point. The hydraulic pressure level in the acting chanber is also adjusted. The press is generally used for bending metal sheets. By this invention, an optimum stroke length of the ram in the press can be easily determined without experimentally processing and, therefore, wasting sheet metal workpieces.
