<p>The present invention relates to a device for applying runners (32) on closure profiles (22), comprising various actuator means (110, 120, 130, 140) driven by a common driving means (150), including a wheel (110) for driving a chain of runners (32) temporarily linked together by breakable bridges (34) in order to transfer successively each runner (32) towards an application station on the closure profiles (22); characterised in that the device includes means (170) for manually disengaging the driving wheel (110) relative to the other actuator members (120, 130, 140). The invention also relates to a method and a machine implementing the above-mentioned runner application device, and to the closure profiles and bags thus obtained.</p> |
