Abstract: A linear indexing machine comprising a continuously driven conveyor for conveying a plurality of pallets to and from a plurality of index stations to allow work functions to be performed on work pieces carried by the pallets. At each station, the pallets are detached from the conveyor while at conveyor speed; decelerated; stopped for a predetermined time interval to allow a work function to be performed on their work pieces; accelerated to conveyor speeds; and then attached to the conveyor for conveyance to the next station. An index cam follower is carried by each pallet and an index cam, driven in synchronism with the conveyor, is disposed at each station for co-acting with the cam followers of the pallets to decelerate, stop, and accelerate the pallets.
