A sequencing unit operating along a feed path of a number of opening devices for attachment to respective sealed packages of pourable food products includes a conveyor for conveying the opening devices arranged in at least one line, and a releasable stop mechanism interacting with the opening devices downstream from the conveyor along the path. The stop mechanisms are normally set to a first configuration, in which they arrest the opening devices along the path, and are movable into a second configuration allowing travel of the opening devices. The unit also has a push mechanism traveling at predetermined intervals past the stop mechanism to move the stop mechanism from the first configuration to the second configuration, so that the opening devices are fed in sequence and at a predetermined rate through the stop mechanism.
