Apparatus for producing composite corrugating media for the manufacture of corrugated fiberboard and method of making same |
摘要 |
The present invention relates to a method and apparatus for laminating two webs of corrugating medium to produce a composite corrugating medium for the manufacture of corrugated fiberboard. The method essentially consists of the steps of (a) applying a coat of a water-soluble adhesive onto one side of at least one web of a first and second corrugating medium; (b) conveying the first and second corrugating medium over the surface of a first heating cylinder such that the water-soluble adhesive is between the first and second corrugating medium to join them together into a loosely bound composite corrugating medium, wherein heat is applied to one surface of said composite corrugating medium through the first heating cylinder; and (c) passing the opposite surface of the composite corrugating medium to a second heating cylinder to subject the composite to a second heating step. The present invention contemplates an apparatus for carrying out this invention.
