An apparatus for separating articles advanced in series and in a mutually contacting relationship, includes a first conveyor advancing the articles in a series and in contact with one another on a first conveyor surface, and a second conveyor arranged for receiving articles from the first conveyor and advancing the articles in series on a second conveyor surface. The second conveyor has a conveying speed greater than that of the first conveyor, whereby the articles are advanced on the second conveyor surface in a spaced relationship to one another. There is further provided a third conveyor having article carriers which convey the articles downstream of the second conveyor surface as viewed in a direction of article advance. A suction device generates, in zones of the first and second conveyors, a force exerted on the articles and oriented for pressing the articles against the first and second conveyor surfaces.

In an apparatus for separating articles advanced in series and in a mutually contacting relationship, including a first conveyor advancing the articles in a series and in contact with one another on a first conveyor surface; said first conveyor having a discharge end; a second conveyor having an input end receiving articles from said discharge end of said first conveyor and advancing the articles in series on a second conveyor surface; said second conveyor having a conveying speed greater than that of said first conveyor, whereby the articles are advanced on said second conveyor surface in a spaced relationship to one another; a transfer location situated between and being bound by said discharge end of said first conveyor and said input end of said second conveyor; and a third conveyor having article carriers mounted thereon; said article carriers being arranged for conveying the articles downstream of said second conveyor surface as viewed in a direction of article advance; the improvement comprising suction means for generating, in zones of said first and second conveyors, a force exerted on said articles and oriented for pressing said articles against said first and second conveyor surfaces; said suction means comprising a first suction arrangement extending along a length portion of said first conveyor up to said transfer location and a second suction arrangement extending along a length portion of said second conveyor up to said transfer location whereby during the transfer of any two contacting consecutive articles from the first conveyor to the second conveyor, the trailing article of the two consecutive articles is exposed to the pressing force of the first suction arrangement on the first conveyor and simultaneously the leading article of the two consecutive articles is exposed to the pressing force of the second suction arrangement on the second conveyor to positively separate the leading article from the trailing article by a pulling force pulling away the leading article from the trailing article; said pulling force being derived from the pressing forces of said first and second suction arrangements and the speed difference between the first and second conveyors.
