摘要： Filters (2) dispensed from a hopper (6) are taken up by aspirating flutes (13) on the periphery of a rotating drum (11) and transferred to a pneumatic feed duct (5) along which each one is propelled in turn toward a filter tip attachment machine (4). A transfer station (27) located beneath the drum (11) is occupied by a body (14) of which a first portion functions as a concave sealing block (19) capable of movement between a first position of contact with the cylindrical face of the drum (11), and a second position distanced from the drum (11) ; the feed duct (5) includes a channel (29) incorporated into a second portion (20) of the body (14), and therefore integral with the sealing block (19), so that with the block distanced from the drum (11), the channel (29) assumes a position in which the opposite ends are exposed and accessible, allowing an operator to clean the duct or remove a blockage.
