In an assembling apparatus for slide fastener stringers with spaced sections, the leading element of the element row in the leading stringer is detected by a probe inserted into the guide groove of the binder member for the elements and the engagement of the leading element and the claw of the probe retards the progress of the leading stringer leading to the retardation of the rotation of the pulling roller for the leading stringer as a consequence while the rotation of the other pulling roller for the trailing stringer, which is connected to the first pulling roller through a differential transmission mechanism is accelerated whereby the trailing stringer is forwarded with increased velocity to rapidly catch up with the leading stringer so that both of the stringers are brought into right alignment to be exactly interengaged in the binder member without mismatching. |
