Description

Technical Field

[0001] The utility model relates to the technical field of paper barrel production, in particular to a paper barrel rolling machine. Background Art

[0002] Paper drums, also known as fiberboard drums, are made from eight layers of kraft paperboard bonded together with a polyvinyl alcohol solution. The lid and bottom are machine-bonded from five layers of plywood. With increasingly stringent environmental requirements and pressing environmental challenges, paper drums are becoming increasingly popular and widely used.
