- 1 - Abstract: The disclosure relates to an apparatus for the production of reinforcing non-woven net fabric which is provided with selvage nipping devices for nipping selvages of a weft sheet or loop end portion of weft thread reaches at both sides and advancing the weft sheet with the thread reaches laterally tensioned. An adhesive applying device coats thermoplastic adhesive onto the weft sheet being nipped by the selvage nipping devices, except at the sel- vage portion of the weft sheet. A heating device dries and melts the adhesive on the weft sheet and a sheet pressing device presses and bonds together the weft sheet with the melted adhesive thereon and a preheated warp sheet. Accordingly, during the application of the adhesive, the thread reaches can be maintained exactly straight and in parallel and spaced relationship, and no adhesive is applied to the warp thread, other than at the intersecting points with the weft sheet. Further, a sheet press device has its peripheral surfaces controlled to keep the temperature lower than the softening point of the ad- hesive, whereby the composite of weft and warp sheets can be easily and rapidly released from the sheet pressing device.
