ABSTRACT:
Cigarette sticks are transferred from a cigarette maker to a filter tip attachment by a unit that includes a conveying roller made to rotate in a first feed direction and furnished with channels aligned on a second direction transverse to the first direction. Each channel accommodates a single stick, directed onto the conveying roller by way of an impeller device, and presents two longitudinal areas designed to make contact progressively with corresponding longitudinal areas of the stick as it advances into the channel, the effect being to create a chamber between the stick and the part of the channel lying between the two longitudinal areas of contact, which is connected to a source of negative pressure.
