The chains 13 are supported on rollers 14 running on a track 11 along the upper run and by rollers 17 carried by supports 16 secured to rods 15 interconnecting the chains 13, the rollers 17 running on a track 12 on the lower run. The distance between the flanges 22, 23 on the members 21 is sufficient to allow movement with the chains around the driving sprockets at the ends of the upper and lower runs. The flanges of the channels may have depressions in which to locate the rollers 19 to assist in driving the platens, and stop means may be provided on the conveyer to halt movement of the platens whilst the chains continue to move.
