ABSTRACT:
Apparatus and method for folding cohesive coated material like corrugated paper and coated film about three dimensional solids like paper products, toys, machinery and books for transport is accomplished by a framework supporting a roll or other supply of the cohesive coated material, a guide for the material, a platform for a cutting blade and an end frame or mandrel and a movable U-shaped crimping frame for forcing the leading sheet of coated paper or film back into contact with itself around the object to be packaged.
The apparatus may support horizontally a roll or other supply of cohesive coated paper or film that is conducted over a horizontal shelf beneath a restraining strip and then passed over a rounded mandrel until a proper length is beyond the mandrel so as to encompass the object to be wrapped or packaged, the paper being pulled over the mandrel by contact with a crimping frame of rounded tubing that is articulate with respect to the mandrel. Then the crimping frame is reversed in motion and the paper or film is returned to a vertical position in contact with the object and is then forced about the mandrel by the crimping frame to adhere to itself on three sides of the object and be cut from the roll end when crimping is complete. The crimping of the material is very important to good packaging, but contact pressure alone is sufficient to seal the package and may be accomplished by either the preferred cylindrical tubing or by angle or square tubing.
