Abstract (en)

In order to improve manufacturing precision, the present disclosure provides an apparatus for manufacturing a paper cigarette filter, the apparatus including: a supply device (10) configured to withdraw paper tow (211) made of a paper material at a predetermined withdrawal speed and transfer the withdrawn paper tow; a crimping device (20) disposed on one side of the supply device that corresponds to a direction in which the paper tow is transferred and including a pair of crimping rollers (21) from which a plurality of crimping protrusions protrude radially outward in a circumferential direction so that the paper tow is crimped while passing between the crimping rollers; a cutting device (30) disposed on one side of the crimping rollers and including a plurality of cutting blades configured to cut the paper tow so that the paper tow is separated into a plurality of separated paper portions (211a, 211b, 211c) at predetermined gaps in a width direction; an embossing formation device (40) disposed on one side of the cutting device and including an embossing roller (41) having a plurality of embossing protrusions (41a) protruding from an outer circumferential surface thereof so that a plurality of capsule-holding embossing grooves are formed to be recessed in a surface of at least any one of the separated paper portions; and a capsule addition device (80) disposed on one side of the embossing roller and configured to add a capsule (220) from top to bottom at predetermined gaps in a longitudinal direction on the surface of at least any one of the separated paper portions in which the embossing grooves are formed.
