A packing method and unit to pack articles, includes: moving first seats by a first conveyor and second seats by a second conveyor along first and second paths at first and second moving speeds, respectively; and cyclically transferring an article from a first seat to a second seat in a transfer station. The first seats and second seats each designed to house an article. During normal operation with no rejected articles, the first moving speed is functionally equal to the second moving speed, and the same number of first and second seats pass through the transfer station in a given time interval. Where at least one article is rejected in a first seat, the second moving speed is functionally decreased relative to the first moving speed so that two first seats (one containing the rejected article) passes through the transfer station in the time interval as one second seat.

A conveyor system for grouping containers including a conveyor module configured to convey and meter a stream of containers of various dimensions a first star wheel and a second star wheel configured to move a plurality of first containers along a first travel path, wherein the first containers each have a first geometric center, and wherein the first travel path is defined by the geometric center of the first containers, and a third star wheel and a fourth star wheel configured to move a plurality of second containers along a second travel path, wherein the second containers each have a second geometric center, and wherein the second travel path is defined by the geometric center of the second containers, wherein the first travel path and the second travel path are substantially similar.

A star conveyor for containers which includes at least one supporting body which can move rotatably about a rotation axis, and supports peripherally a plurality of gripping devices, which are distributed around its rotation axis and are each adapted to retain a respective container to be conveyed; each one of the gripping devices includes at least one respective pair of gripping arms; at least one gripping arm of such pair of gripping arms includes a main body and at least one adapter element which is detachably attached to the main body and is interchangeable with at least one other adapter element of a different type, in order to vary the configuration of the at least one gripping arm according to the type of container to be conveyed.
