摘要

According to the method, a random axial flow of arriving trays (P) of articles (A) is accessible, a stack of blanks (F) is accessible, a synchronized axial flow of trays (P) is formed, all the trays (P) are transferred from the synchronized axial flow (P) to constitute a synchronized axial flow of lots (L) of the desired format and frequency, each lot (L) is separated from the preceding and/or subsequent lot (L) by a vacant space (5a, 5c) having the length of the length of one article (A) or a multiple thereof, the pitch thus being variable and matched to the length of the lot (L), the blanks (F) are taken from the stack on demand in accordance with the trays (P) to constitute a synchronized flow of blanks (F) matching the synchronized flow of lots (L), each blank (F) being separated from the preceding and/or subsequent blank by a vacant space (19) having the length of the length of one article (A) or a multiple thereof; from the synchronized flow of lots (L) and the synchronized flow of blanks (F), each lot (L) of articles (A) is made to engage with each blank (F) before folding the blank (F) around the lot of articles (A) and securing the blank to itself.
