<p>PURPOSE:To achieve the connection of cords easily irrespectively of the angle of the cord section by fitting, capably of rising or lowering and rotating arround a vertical center line, an end edge chuck for keeping attachably and releasably the tip edge of an unconnected rubber-covered core on a movable table. CONSTITUTION:An end edge chuck 29 is positioned so as to be coincident with width direction, and said chuck is lowered, positioning its rotary center at the origin of coodinates. The under surface of the end edge chuck 29 is placed in pressure contact and slightly back from the tip edge Aa of an unconnected rubber-covered cord A, and suction force is applied to the suction hole 29C of said under surface, while synchronizing it with the pressure contact of said chuck 29, whereby a little rear side of the tip edge Aa of the unconnected rubber-covered cord A is kept at the end edge chuck 29 by suction. By the operation of the air cylinder 26 for elevating and lowering, said chuck 29 rises and lifts up said tip edge Aa. While synchronizing with said lifting up, the motor for angle, the motor for X axis and the motor for Y axis are respectively rotated. The tip edge Aa is pushed to a rear end edge Bc by the under-surface of the bar 33 for pressure welding.</p> |
