Abstract: The system for regulating the feed of articles to a wrapping machine, includes a conveyor for feeding a series of longitudinally-spaced articles to the wrapping machine sensors for detecting the position of each article on the conveyor at predetermined instants, and a control circuit for varying the speed of the conveyor in dependence on the output signals from the sensors, so that the articles are fed to the wrapping machine in a predetermined phase relation relative to it. The sensors are arranged to provide signals indicative of the degree of any deviation of each article from the correct position in phase with the wrapping machine and the control circuit is arranged to correct the speed of the conveyor in proportion to the degree of deviation detected.
