WELDING APPARATUS FOR PLASTIC-MADE CORRUGATED BOARD AND MANUFACTURING METHOD FOR PLASTIC-MADE CORRUGATED BOARD PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a welding apparatus for a plastic-made corrugate board and a manufacturing method for a plastic-made corrugate board product which are free from the whitening of a jointed part of the plastic-made corrugate board and from the damage to a planeness by deformation and also capable of jointing the plastic-made corrugate board at a high accuracy. SOLUTION: The welding apparatus for a plastic-made corrugate board welds the plastic-made corrugate board connected each other plastic-made plates comprising a couple of both sides by a rib, and is provided with a welding means for welding the plastic-made corrugate board with another plastic-made corrugate board and/or another plastic-made member by heating under pressing a contact piece for heating on the surface of the plastic-made corrugate board described above and melting the plastic-made corrugate board.
