On a machine (1) for producing smoking articles, such as cigarette filters, a feed unit (24) for feeding additive elements (25), such as menthol capsules, into fibrous material, such as filtering material, has at least one hopper (26) containing a mass of additive elements (25); and a transfer device (28) which, at the input, withdraws the additive elements (25) successively from an outlet (27) of the hopper (26), and, at the output, deposits the additive elements (25) successively into the fibrous material. Between the input and output, the transfer device (28) increases the spacing between consecutive additive elements (25), so as to withdraw the additive elements (25) from the hopper (26) with a pickup spacing (Pl), and deposit the additive elements (25) into the fibrous material with an out-feed spacing (P2) greater than the pickup spacing (P1). |
