Disclosed herein is an apparatus for the exiting of products, particularly cigarettes, from a wrapping/packing line for the said products, able to check that the wrapping on all the products has been properly executed and to guarantee the succession continuity to the equipment located further along the line. The apparatus comprises means for moving the products intermittently along an exit channel in time with the inching motion of the wrapping/packing line; retainer means synchronized with the movement of the said transportation means, movable from a position in which the products are held, one next to the other, along the channel to a position in which one product at a time is allowed to enter the said channel; feeler means for detecting the presence or the absence of a product at the entry point to the channel; electro-mechanical coupling means fitted on the means for transmitting the intermittent motion to the aforementioned transportation means and to the said retainer means. The feeler means are electrically connected to the coupling means and to the feeler means for checking that the wrapping has been properly executed, in such a way as to cause the transportation means and the retainer means to be halted, as well as to cut off the said feeler checking means whenever they detect the absence of a product at the entry point to the aforementioned channel.
