Abstract
A link conveyor is proposed which includes a first set of helical coils or spirals connected together in interdigitated parallel disposition to define a base structure providing adequate strength and dimensional stability in the conveyor and a second set of interdigitated helical coils or spirals connected together and to the base structure and forming a supplementary structure for protecting the said base structure against damage or undue wear. The base and supplementary structures may be arranged to form a single layer conveyor or may comprise two separate plies connected together by support coils to define a Duplex structure. The conveyor is of particular application to papermachine clothing suitable for dryer fabrics, forming fabrics and base structures for press felts.
