    摘要: A polyamide composition comprises (a) 50 to 99 wt. % of a polyamide; and (b) 50 to 1 wt. % of a modified polyolefin which is modified with 0.001 to 10 mole % of an adduct component selected from alicyclic carboxylic acids or functional derivatives thereof which has a cis-form double bond in the ring, which can be substituted with a nonmodified polyolefin at a ratio of 1 to 90 wt. parts per 100 wt. parts of said modified polyolefin.

    摘要: The present invention relates to an abrading machine comprising two abrading devices, a carrier member that is provided between the two abrading devices so as to be movable toward and away from them. Gripping elements are mounted on the carrier member so as to be located on opposite sides of the abrading devices to hold a workpiece to be abraded. A plurality of supporting members are also provided on the carrier member to rotatably swing up and down in order to support the workpiece as it is abraded by the different abrading devices. The gripping elements are pivotably attached to the carrier member and are designed to swing with respect to the carrier member in the direction of movement of the carrier member.
