Each first and second link comprises a pair of spaced side members. There is a pivotal joint between neighbouring links. Spikes are formed on a plurality of first links to receive and locate a load. The trackway comprises a base member in the low friction layer on the base member and dimensioned to receive the second links. Side plates are spaced from each side of the base member. The side plates extend upwardly to be alongside the chain when the chain is in position. The side plates can be adjusted on the base to vary the distance from the base. Low friction distance pieces on the inner side of the side plate extend to contact and locate the chain. The chain is thus held on a fixed course and movement inwardly of the low friction distance pieces can compensate for wear in the chain.

  • Patent number: 4954066
    Abstract: A chain guide structure for guiding a conveyor chain through a thermoforming machine to protect the chain from plastic chips and other debris. The chain guide includes a support rail structure for supporting an upper run of conveyor chain, and a spring steel cover sheet overlying a track defined by the support rail and in close proximity with the chain to serve as a cover and thereby protect the chain from contamination from foreign material. Additionally, the chain includes a series of spikes to penetrate a plastic sheet and thereby carry it through the machine, wherein the chain guide structure has a width sufficient to permit lateral outward expansion of the plastic sheet as it is heated in the thermoforming machine. An upwardly inclined portion of the guide structure provides a cooling section to permit the plastic sheet to cool as it is carried away from a forming section of the machine.
