ABSTRACT:
A device for wrapping a glued junction band (T) around an axially arranged pair of cigarettes (S) with a double filter interposed therebetween, wherein the cigarettes and filters are aligned by terns on a rotary drum (1) comprising rolling sectors defined between peripheral gabled ridges (2) on the periphery of the drum. In each of said sectors, the axial rolling movement of a tern comprising the cigarettes and double filter, which promotes the wrapping of the junction band (T) therearound, is caused by a relative sliding movement between the periphery of the drum (1) and an endless chain-track (3), the articulated links (11) of which comprise, each, an arcuated rolling face or sole (111) and are positively guided, perfectly concentrically with the drum (1), along a pre-determined angle thereof, depending upon the length of the band and upon the rate of the relative movement, the radial constant spacing between the soles (111) and the opposite rolling sectors of the drum (1) being such as to engage laterally, by a gentle pressure, the terns to be wrapped in the respective band (T). Each of said rolling faces or soles (111) of the chain-track links (11) has an inlet sharp corner (211), on the upstream side of the rolling sole, with respect to the direction of the peripheral movement of the drum (1), so as to form an abutment shoulder to align the terns of cigarettes (S) and interposed double filter, if necessary and before they begin rolling, and to make sure that the rolling movement of the terns begins with each tern in perfect alignment.
