Description

Technical Field

[0001] The utility model belongs to the technical field of long roll backing gluing, in particular to a long roll automatic backing gluing device. Background Art

[0002] Gluing the back of a long roll is a technology that evenly applies glue on the long roll. This process is usually completed using automated equipment.

Through the operation of automated equipment, efficiency can be improved, manual operations can be reduced, and the glue coating can be ensured to be more uniform and stable. This technology is widely used in printing, binding and other industries, and is one of the important processes for realizing long roll processing.
