ABSTRACT:
A method and apparatus for connecting harness cords to the heddles which are eventually to be used in a weaving machine. A harness cord is threaded through an upper eyelet of the heddle and is turned back on itself with the connection being fixed by a shrink hose which is shrunk over the eyelet, thereby clamping the harness cord to the upper eyelet. An apparatus is movably mounted on an assembly frame between the various harness assemblages. At each location on the frame, the apparatus holds the free end of the harness cord after it has been threaded through the eyelet on the heddle. A friction brake is utilized to hold the free end of the harness cord while the apparatus effects a tightening of the harness cord and a drawing of the eyelet into the unshrunk shrink hose. A cutting mechanism is provided to sever the harness cord between the eyelet and the friction brake. As the eyelet is pulled down into the center of the shrink hose, the harness cord is clamped between the inner sidewall of the shrink hose and the eyelet. A source of heat in the apparatus effects a shrinking of the shrink hose, the harness cord is clamped between the inner sidewall of the shrink hose and the eyelet. A source of heat in the apparatus effects a shrinking of the shrink hose and a securement of the harness cord to the heddle. The apparatus also includes structure for effecting an alignment of the thread guides in a predefined common plane and maintains this alignment throughout the connection of the harness cord to the heddle.
