An apparatus for gripping, guiding and transporting opposite longitudinal side edges (10) of slit, deformable strip (12) for forming expanded mesh sheet. One chain (22) of each of two pairs of opposed endless chains (21, 22) has a longitudinal recess (36) adjacent a longitudinal planar side edge of the strip (12) for receiving the planar edge (10) of the strip (12) therein and the opposed chain (21) of each of said pairs has a plurality of equispaced sharp projections (32) for penetrating the longitudinal planar side edge (10) of the strip (12) whereby the said edge (10) is effectively gripped between the opposed chains (21, 22) during expansion. |
