摘要：The parts or profiles produced from synthetic materials, preferably

theremoplastics, are of high mechanical strength by virtue of a molecular orientation dueto rolling compression stretching within the roll nip of at least one pair of pressure orcompression rolls at roll and material temperatures below the crystalline melting pointor the softening temperature of the synthetic material and above 303 K whilst stretchingunder pressure. The rolling compression stretching of the said parts or profiles isperformed with the same or approximately the same circumferential speed of thepressure or compression rolls or without friction at pressures of 20 to 250 MPa,

preferably 25 to 150 MPa, with a compression stretching ratio of over 1.1, preferably 2.1.The apparatus comprises one or more pressure rolls, of which at least one is supportedin bearing bodies which can be adjusted in height, depth and/or to the sides, devices fortemperature control, preferably heating the roll surface, and devices in connection withthe bearing bodies of the adjustable roll for withstanding linear loading in the roll nip of950 N/mm to 5,500 N/mm.
