ABSTRACT:
Articles are supplied to a conveyor by feeding primary articles from a primary supply, seriatim, to a conveyor. The conveyor is driven at a first speed consistent with the supply of primary articles so that primary articles are uniformly spaced on said conveyor. The presence of a predetermined number of supplemental articles in a supplemental supply is detected, and used to increase the speed of the conveyor to produce space on the conveyor sufficient to receive the predetermined number of supplemental articles. The predetermined number of supplemental articles are fed, seriatim, to the conveyor such that the supplemental articles are uniformly spaced on the conveyor with the same spacing that the primary articles on the conveyor.
