Abstract: A robot joint driving apparatus has an improved structure, a robot having the same, and a cable linkage method of the robot joint driving apparatus. In the robot joint driving apparatus, lines of a cable to drive a robot joint unit are connected plural times in parallel, thereby increasing torsional stiffness of the robot joint unit.

Abstract: In a process for continuously pulling a web of tows of carbonizable material under tension through an oxidizing oven, the web is introduced into the oxidizing oven by initially feeding a leader in the form of a web of heat-resistant cloth through the oven and then heating the oven if the oven is not already hot. The trailing edge of the leader which remains outside of the oven is then spliced to the leading edge of the web of carbonizable tows, and the leader is used to pull the web of carbonizable tows into and through the hot oven. Use of the heat-resistant leader greatly minimizes wastage within the web of carbonizable tows. Splicing of the trailing edge of the lead to the leading edge of the web of carbonizable tows is accomplished by taping, stitching and folding the two edges to form loops therein into which elongated rods are inserted. The two edges are then secured within a splice bar, the opposite halves of which define slots for receiving the two edges and the included rods.
