device and method for the formation of groups consisting of a variable number of products

摘要

Device for forming groups (G) composed by a variable number of products (P), comprising:a path of advance (26) along which, in use, a continuous array of products (P) advances along a direction of advance (28) with the products (P) in mutual contact,an arresting member (36) against which, in use, the continuous array of products (P) comes in arresting contact at the end of said path of advance (26),a conveyor device (16) to remove from the continuous array successive groups (G) of products (P) from a terminal part of the array in contact with the arresting member (36), anda regulator device (39) to vary selectively the position of the arresting member (36) along said direction of advance, andan accompanying device (64) to support the array of products (P) and control the velocity of displacement towards the arresting member (36).
