Title: METHOD OF MANUFACTURING A PACK FOR OVOIDAL OBJECTS ABSTRACT OF THE DISCLOSURE A cardboard pack for egg, or the like, is made of two slitted blanks, the longer one of which is bent into flat-topped and flat-bottomed waves. After the wave bottoms are bonded by adhesive to the flat blank, the wave tops are tucked in and the waves flattened mechanically. After the adhesive bonding, the solid cross-strips at the ends of the flat blanks become unnecessary and are cut off. Precautions are taken to avoid undesired adhesion of strips previously separated by slitting. With the waves flattened, the blanks can be easily stored or transported. The blanks are set up at the place of filling by mechanically raising the waves, bending up the sides of the back to form pockets, inserting the good, bending over the top strips, and securing them together on their line of abutment. The shorter set of blanks is preprinted.
