The manufacture of round cord is carried outcheapest and best by means of a machine made by Francis Shaw ofManchester (fig. 63). The separate sheets, united with their inser-. FiG. , are rolled up, and any number of such strips up to twelveare put under the rolling machine, formed of two bench-tops. Theupper bench-top, tilting increasingly as it advances, presses on thestrips in its forward motion and rolls them into the form of roundcord; insertion and covering can be rolled up in one smooth cord is desired the covering is left out, and, ifnecessary, a layer of rubber is run on to the cord by means of MANUFACTURE OF SOFT-RUBBER ARTICLES. 145 the tube machine. The cord is vulcanised in a straight length,in a hose-heater, after having been previously wrapped in the samemachine. Square and flat Tucks cord is first made up in the formof round cord in the same way, and is afterwards passed throughthe shaping-machine (fig. 64) and pressed into shape. This machinepossesses the great advantage over the ordinary grooved rolls, thatby means of it cord of any dimensions can be made by merelychanging the upper wheel. Tube-rings and similar arti
