A spacer and conveyor mechanism for a packaging machine in which articles can be conveyed along a feed path and grouped together for subsequent packaging of each group into a discrete unit. The mechanism has a series of spacer and conveyor elements (94) constrained cyclically to execute a working and return motion such that the elements move along a working path in the feed direction of the articles during which the elements interfere with the articles in the feed path so as to form and convey said groups along the feed path and move along a return path opposite to the feed direction of the articles during which said elements are remote from said articles. The working and return paths are substantially parallel to the feed path, and the spacer and conveyor elements each have an operative face adapted to convey said articles in spaced relationship. The elements are mounted so that they are held throughout their cyclic movement with their operative faces facing towards the feed path. |
