ABSTRACT:
An apparatus for inserting a slider onto a flexible zipper tape, comprising: a zipper tape guide that supports a section of zipper tape in a slider insertion zone and guides advancement of the zipper tape along a line; a mechanism for displacing a slider from a pre-insertion position to an inserted position on the section of the zipper tape located in the slider insertion zone; and a slider guide for guiding the slider from a transition point to the pre-insertion position. The slider guide is configured so that the slider travels along a generally U-shaped path in its transit from the transition point to the pre-insertion position. The slider guide may be a channel configured to maintain one end of the slider constantly in the lead as it moves along the channel.
