Abstract

PURPOSE:To produce a cushioning package material having no disordered or falsely welded threads, by moving upper and lower molds provided on a tip of an extruder horizontally, reciprocally in opposite directions with one another so that the threads extruded from both the mold may be crossed each other and pressed to be bonded. CONSTITUTION:While a molten synthetic resin in an extruder 1 is extruded as solid or tubuler threads S, S' through discharge openings 21, 31 of an upper 2 and a lower mold 3, a pinion 10 meshed with racks 9, 9' extending laterally from molds 2, 3 are rotated forward and reversely to reciprocate repeatedly the molds 2, 3' horizontally and generally normally to the extrusion direction of the resin, so that the threads S, S' are crossed. Then the threads S, S' are introduced into a press bonding apparatus 4 and welded at their crossed portions to become in the form of a net, while a synthetic resin film or band 5 is introduced from an unwinding roller 51 into the press bonding apparatus 4 to be welded on one surface of the net of the threads S, S', and thereafter the product is wound onto a wind-up machine 8 via a cooler 6 and a houl-off 7.
