A tape-form packaging system is provided having an elongated carrier tape on which a plurality of elongated article-receiving loops are mounted on a face of the tape in transversely oriented relationship to the longitudinal axis of the tape with the axial ends of the loops spaced a distance inwardly from the longitudinal edges of the tape. Gating elements are affixed to the carrier tape with a gating element positioned between each axial end of a loop and the adjacent longitudinal edge of the carrier tape and operative to block axial movement of an article into or out of the respective loop. The carrier tape is flexible and upon flexing of the marginal edge portion of the tape, the gating element is displaced out of blocking relationship to the loop permitting axial displacement of an article into or out of a loop. A tape-manipulating apparatus is provided for flexing of a marginal longitudinal edge portion of a strip-form tape packaging system to temporarily remove a gating element from blocking relationship with respect to a respective article-receiving loop. Guide rails are provided to engage with the longitudinal edges of the tape as it passes through an article-transfer station to prevent displacement of the tape in its plane transversely to its longitudinal axis and to restrain the tape against displacement laterally with respect to its plane. A bending rail is positioned in the article-transfer station to bring an edge of the rail that is inclined to the path of movement of the tape into contacting engagement with the tape and effect flexing of a marginal edge portion of the tape a sufficient distance out of the plane of the tape as to displace the gating elements out of blocking relationship to an axial end of a respective loop. An elongated back-up rail is supported in contacting engagement with the face of the tape opposite the loops and at a position to maintain the loops in a planar path of movement through the article-transfer station.
