The container speed adjusting apparatus has one or more resiliently compressible components which facilitate alteration of the translational speed of the container, as well as alteration of the rotation thereof. Among the preferred approaches to providing such resiliently compressible means are to have endless belts supported and driven by primary pulleys with secondary resiliently compressible pulleys in engagement with said belt and disposed between the primary pulleys. The endless belts may be provided with specifically configurated resiliently deformable portions, such as weakened portions in the belt, openings in the belt, or radially outwardly projecting elements. In general, a pair of container speed adjusting apparatus units will be employed and will be so spaced that the size of the path therebetween is less than the diameter of the container at the point where the container speed adjusting apparatus will contact the container. If desired, both container speed adjusting apparatus units may have essentially the same construction. In one embodiment, a resiliently compressible wheel is provided in lieu of one or both of the units having the endless belts. In a preferred practice, the container speed adjusting apparatus is employed to reduce the translational speed and rotation of the containers which may be bottles or jars made of plastic or glass. ##
