<p>A mechanical conveyer for e.g. tubular preforms (2) has two moving extruded profile (7, 8) belts separated by a gap (10) whose inner faces incorporate groove guides (11, 13). The guides locate against and hold the tubular preform collar (5). The conveyer can transport the preforms along horizontal, vertical and inclined planes and through changes of direction of 180 or 360 degrees.</p> |
