An example of the use of animal glue adhesives in the paper converting field is for the covering of rigid boxes and containers with paper, typically lithographed decorative labels in setup box manufacturing. Animal glue adhesives are preferred because of their con­trolled tack, nonwarp properties, and permanence of adhesion. In this operation, a thin paper cover is fed through a roller applicator and coated with adhesive. The paper is delivered to a belt and then to a spotting station, where the box is placed on the cover mechanically or by hand. The machine then wraps the cover material around the box and ejects the finished box. Animal glue adhesives are also used for record albums, paper laminating, convolute and spiral cans such as oil and juice cans, and other specialty box operations, such as cosmetics and cigarettes.
