Sheet Coating Machines are adhesive roll coating machines that are used to apply a thin layer of glue to large labels, die cuts, sheets of foam, chipboard and similar materials.
A sheet coating machine has a large glue tank which serves as an adhesive reservoir. A tank roll dips into the glue and transfers it to the coating roll. The gap between the tank roll and coating roll is adjustable and precisely controls the amount of glue that is carried up onto the coating roll. The glue is applied to the bottom of the part, and the part is pressed against the coating roll by either a single or dual feed roll.
Sheet coating machines are available in several different feed roll arrangements for application of glue to parts from paper thickness to 5” thick, and are available in coating roll widths from 9” to 50”.
