ABSTRACT:
A TAB carrier is loaded into the bottom position of a bottom-loading stacking magazine using a slider which conveys the TAB carrier from a first loading position to a second unloading position located beneath the stacking magazine. The slider has a first horizontal surface on which a TAB carrier is initially placed and a second horizontal surface which is elevated above the first horizontal surface. A ramp surface connects the two horizontal surfaces. A retractable knife blade engages the TAB carrier and permits the TAB carrier to be carried by the slider only from the first position to the second position and prevents the TAB carrier from being carried by the slider from the second position back to the first position. A specific embodiment of the knife blade includes a front surface configured as an inclined cam surface which is engaged and pushed vertically downward by the TAB carrier as the TAB carrier is moved horizontally by the slider from the first position to the second position and a rear vertically-oriented surface which engages the TAB carrier and prevents horizontal movement of the TAB carrier as the slider is returned from the second position to the first position.
