Abstract
A pin wheel feeding device includes a housing capable of being rotated about an axis. A plurality of substantially identical pins are disposed within the housing in respective alignment with a plurality of openings. Each pin includes a pair of opposing guide members. A cam member disposed within the housing is capable of being fixed in position relative to the housing. The cam member has a track formed thereon with which each of the pins is engaged with the pair of guide members thereof being located on either side of the track. The width of the track at first, second and third segments thereof is substantially coextensive with the locus of points traced by the closest adjacent points on the pair of guide members of each pin during movement of the pins along the first, second and third segments of the track.
