摘要

An apparatus for gripping, guiding and transporting opposite longitudinal side edges of slit, deformable strip for forming expanded mesh sheet. One chain of each of two pairs of opposed endless chains has a longitudinal recess adjacent a longitudinal planar side edge of the strip for receiving the planar edge of the strip therein and the opposed chain of each of said pairs has a plurality of equispaced sharp projections for penetrating the longitudinal planar side edge of the strip whereby the said edge is effectively gripped between the opposed chains during expansion.
