The invention provides an improved apparatus for producing recilinear mesh netting from threads containing thermoplastic material. In manufacturing netting in accordance with the invention transverse threads are drawn across parallel longitudinal threads and discrete masses of thermoplastic material in heated condition are moulded in respective dies about the thread crossings. The path of each transverse thread between the dies is extended by an amount corresponding to the contraction of the transverse thread which occurs in the moulding operation. The apparatus is preferably fitted with adjustable thread diverter elements between each die so that the extent to which the transverse thread deviates can be varied to correspond with the shrinkage incurred in each particular case, depending on the nature of the threads employed and on the number of longitudinal threads or the mesh size. Netting produced in accordance with the invention can be used for a variety of purposes for example in sports or for fishing and when electrically conductive threads are employed the netting can be used for electrified agricultural fencing.
