Abstract
Apparatus and method for forming cigarette filters comprise a single or multiple hopper system for forming filter components of single or multiple sizes. The filter components with spaces therebetween are partially wrapped and then conveyed to at least one media applying wheel where media is deposited into the spaces between the filter components. A cover cap is formed and placed over the partially wrapped filter components downstream of the media wheel to thereby completely wrap the filter components. Subsequently, the completely wrapped filter components are joined to tobacco rods with tipping paper.
