Abstract: A machine for folding and applying onserts onto consumer goods such as cigarette packs comprises a continuous roll of preprinted onserts and a transverse cutter assembly for cutting onsert segments from the continuous roll. Each onsert segment includes a pair of side-by-side preprinted onserts. A buckle folder receives each cut onsert segment and folds that segment along at least one transverse fold line. A longitudinal cutter assembly longitudinally cuts each folded onsert segment into two individual onserts. A transport system serially receives the individual folded onserts and moves the onserts along dual diverging paths where a pair of spaced apart lug belt conveyors receives the onserts from the discharge end of the transport system. Each lug belt conveyor includes spaced apart transverse lugs along the length thereof against which the onserts are positioned.

Abstract: A belt-type continuously variable transfer system (15) includes a driving pulley assembly (20), a driven pulley assembly (22) and a V-shaped belt (24) engaged to transfer rotary power therebetween. The driven pulley assembly (22) can include a ratio adjustment mechanism (46) that adjusts the position of a rear sheave (40) relative to a forward sheave (42). The adjustment mechanism (46) includes a motor (170) and a worm gear mechanism (171, 172) that rotates an actuation screw (154). Rotation of the actuation screw (154) is reacted by a split nut (158) so that as the screw (154) rotates is translated along the axis (B) of the driven pulley assembly (22). Translation of the actuation screw (154) exerts pressure against the rear sheave (40) to push it toward the forward sheave (42), thereby altering the drive ratio of the pulley assembly.
