SANDWICH PANEL MANUFACTURING EQUIPMENT AND SANDWICH PANEL MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide sandwich panel manufacturing equipment which can suppress void occurrence and side part contraction by improving outgassing properties from the side part in a sandwich panel strip foaming process. SOLUTION: The sandwich panel manufacturing equipment for producing a sandwich panel strip SP which is produced by foaming a foamable resin core material between face strips arranged oppositely on both upper and lower surfaces has a mixing head 10 for supplying the foamed stock solution composition of the foamable resin core material between the lower face strip 1 to be conveyed and a upper face strip 2 and a foaming chamber 11 for conveying the lower face strip 1 and the upper face strip 2 while carrying out the foaming treatment of the conveyed foamed stock solution composition. The foaming chamber 11 has first conveyer apparatuses A positioned above and below the sandwich panel strip SP and second conveyer apparatuses B positioned in both side parts in the width direction of the sandwich panel strip SP and is conveyed with a nonwoven fabric 24 placed between the conveyance surface of the second conveyer apparatus B and the side part of the sandwich panel strip SP.
