ABSTRACT:
An apparatus for driving and positively spacing attachments along a moving timing chain is disclosed, consisting of at least three chains or belts and means for driving the chains or belts at different speeds and/or directions relative to each other. Attachment carrying lugs are positively held between a first and second chain for a determined distance over a path defined by the first chain, an then released by the second chain to subsequently move into positive engagement between the first chain and a third chain. The speeds and directions of the chains determine the spacing of the lugs and associated attachments.
