Pneumatic transport system using a tube with baffles where the baffles are spaced such that the transported object is always in contact with at least one baffle at a time

摘要

A device for transporting articles, comprising a tube 40 adapted to receive and transport articles F of substantially predetermined length, a pneumatic system for causing a pressure differential across the article F being transported as the article F moves through the device, and a plurality of unslitted, unslotted deformable baffles at spaced-apart locations throughout the length of the tube 40. Each baffle defines an aperture through which the transported article can pass, where adjacent baffles are spaced apart by a distance such that the object is continuously in contact with at least one baffle at a time.
