Method and apparatus of jointing cord fabric and jointing holder in calender line

A method of jointing a cord fabric which is a method of jointing a cord fabric for drawing to supply cord fabric constituted by being woven by constituting warp by a number of pieces of cords from two supply positions set to a supply portion alternately continuously one by one in a calender line for topping rubber to a number of pieces of aligned cords by a calender roll;

• wherein during drawing to supply the cord fabric from one of the two supply positions, by using a jointing holder capable of holding a start end portion of the cord fabric in a stretched state, the start end portion of the cord fabric drawn from other thereof is held by the holder and set to a jointing mounting portion in a state of pasting an unvulcanized jointing rubber member to the start end portion;
• and
• wherein when a final end of the cord fabric on one side of the cord fabric comes closer, a finish end portion of the cord fabric on the one side is pasted to the start end portion of the cord fabric on other side of the cord fabric held by the holder of the jointing mounting portion by interposing the jointing rubber member, the finish end portion and the start end portion are jointed by way of the rubber member by being squeezed from upper and lower sides, thereafter, by removing the holder, the cord fabric on the other side is made to be able to be drawn to be supplied continuously to the cord fabric on the one side.
