be replaced with a similar sheet with a different width of opening for bottles of differing sizes the cleaning may include one or more stages of a detergent wash water rinse and air and vacuum drying slight deviations in the straight sections of the elongated slot will cause the vials to rotate so that all sides become clean using a sheet with an appropriately shaped elongated slot and reversing the directions of some of the conveyor belts changes the number of straight path segments and thus the length of the overall path of the vials through the equipment the adjacent belts may have slightly different speeds with the higher speeds at the beginning of the path to force the vials towards each other where they may support each other in an upright position cleaning the bottles involves passing them along the predetermined path having the straight segments connected by curved sections application_number US 74587791 A description fig1 shows a vial washer generally at 21 having the hood 22 which encloses the actual vial moving and cleaning mechanisms the bottles enter the left of the washer in fig1 from any convenient source fig2 and 3 shows the rotating wheel 25 which holds a supply of vials that will undergo cleaning in the washer 21 the equipment shown however may simply take vials off a conveyor line from other mechanisms such as filling equipment seen best in fig2 the vials 28 enter through the opening 29 from the infeed table 25 from there they travel on to the first straight path segment 30 which carries them towards the front 23 of the washer 21 near the front 23 the connecting path segment 33 changes their direction by 180 degrees and they travel along the straight path segment 34 toward the rear.
