Abstract
A device for orienting tubular preforms which are fed in bulk by a supply device, including two continuous endless conveyors which are disposed side by side and which are equipped respectively with two parallel lines which are separated horizontally from one another by a distance that is greater than the largest cross-sectional dimension of the preforms. According to the invention, the preform-supply device is disposed above one end of the two conveyors. The two conveyors are moved by drive device in opposing directions in order to pivot any preforms that arrive positioned sideways across the conveyors and to drop the longitudinally-oriented preforms into the space between the two conveyors. The orienting device also includes an endless belt for collecting preforms, which extends beneath the two conveyors parallel thereto and which is used to collect and move the horizontally-laid longitudinally-aligned preforms one after the other.
