Patent ID: 10988320

Abstract:
The present invention relates to a screw transport apparatus for bottles, comprising: —a support structure, which extends longitudinally between a bottle inlet 1a and a bottle outlet 1b of the apparatus, and—a spiral-shaped helical body, which is associated with the support structure and extends axially parallel to the support structure between two own axial ends. The above spiral-shaped helical body can be rotated on itself about its own longitudinal axis to move bottles in cooperation with the support structure. The spiral-shaped helical body comprises at least two spiral-shaped seats, which extend coaxially between the two axial ends. They are angularly offset from each other and differ from each other by the shape and/or dimensions of the relative bottle housing compartment defined by each of them. The two spiral-shaped seats are intended to be used alternatively to the other for the transport of bottles having different shapes and/or dimensions.
