Abstract
A system for supplying preforms, of the type including a hopper inclined relative to the horizontal and at the bottom of which are arranged two substantially parallel rollers driven in rotation about their respective axis, and wherein the preforms are delivered in bulk at the upper end of the hopper. The hopper includes at least a wheel for ejecting wrongly oriented preforms which is driven in rotation about its axis, which is inclined relative to a perpendicular to the direction of axes of the aligning rollers so as to sweep the wrongly aligned or nested preforms and to eject them directly towards a lateral discharge orifice of the hopper.
