A dresser apparatus is provided for a strand of blow-molded articles interconnected by shorter flashings. A first pair of first rollers and a second pair of second rollers are of the gear type and are mounted for rotation to define pinching planes therebetween along which the strand is directed. The second rollers are relatively spaced to engage the articles and flashings passing therebetween, and are spaced from the first rollers such that the second rollers engage each flashing or article while a succeeding article or flashing is being engaged by the first rollers. A second moving device rotates the second rollers at a predetermined speed which is greater than the speed of the first rollers. Thus, each flashing or article is pulled from the succeeding article or flashing. A final pair of final rollers is mounted for rotation and defines a final pinching plane rotated (turned) with respect to the second pinching plane so that deformation of the articles caused by engagement with the first and second rollers is compensated for by passage through the final rollers. The dresser apparatus may include a third pair of third rollers spaced from the second rollers by a distance longer than the flashings but shorter than the articles so that the separated flashings fall between the second and third rollers while the articles are passed from the second to the third rollers:
