ABSTRACT:
The grouping of objects, for example unit packaging goods, is accomplished by automatically assembling a stepped formation of the goods and subsequently leveling-off the stepped formation. To accomplish the foregoing, a serially increasing number of the goods are delivered in steps to a grouping station until a maximum number is reached and thereafter the number of goods per step is serially decreased. By exercising simultaneous control over the in-feed of goods and the shifting of the goods step-wise in a direction transverse to the in-feed direction after each delivery, finished groups having a predetermined size and configuration are formed at a downstream end of the grouping station and these finished groups are shifted out of the grouping station in the in-feed direction in synchronism with the in-feed of goods as the number of goods per step being fed in decreases.
