Abstract

1,144,330. Making tubes to standard lengths; rolling tubes. MANNESMANN-MEER A.G. 24 May, 1966 [13 Sept., 1965], No. 23136/66. Headings B3A and B3M. In a method of making seamless metal tubes of equal lengths and weights in plant comprising an extrusion press followed by a rolling and elongating mill, a measuring device is locate therebetween to measure the length of each of the tubes emerging from the extrusion press, the value obtained is compared with a standard length and the speed of the rollers is adjusted to produce finished tubes of substantially equal length. The measured length of the extruded tube is fed into a storage device where the differences in length are stored on punched cards. The measured length is processed by a computer coupled to an electric regulating machine which varies the speed of successive rolls so that the tube is rolled to the required length.
