FIG. 1 is a perspective view of a conveyor belt (broken

At the leading end of the conveyor, the chocolate-?lled
cups are shown separated from the tray and resting upon
the conveyor belt itself. Just behind the leading end
of the conveyor, a tray upper portion is being shown in
the process of being separated from the ?lled cups. Fur

As further important features of the invention, the ap

any suitable means (optionally manually) for sliding the
