In order to protect the longitudinal edges of a link belt against damage or undue wear it is proposed to provide an edge guard comprising a multiplicity of guard elements engaged with the coils of the belt, the elements each comprising a body part for disposition adjacent the edge of the belt and a mounting element for engagement with a respective coil. The body part is preferably flexible, and the body parts of adjacent elements may partially overlie one another in providing a reinforcing wear resistant edge to the belt for protecting the ends of the coils.

Edge guard means for a link belt and a link belt embodying such means

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.

Conveying and like structures

A dimensionally stable warp knitted paper maker's felt includes a plurality of interlocked yarns having a weight per unit length equivalent to at least 500 denier. Laid-in yarns and/or resin may be used to impart the desired stability to the felt.
