Device for cooling adhesive applied to a surface of sack bodies

A device for cooling an adhesive applied to a surface of bag bodies, including a transfer conveyor and a cooling conveyor, wherein the transfer conveyor conveys the bag bodies at a transfer speed to the cooling conveyor and wherein the cooling conveyor conveys the bag bodies taken from the transfer conveyor at a cooling conveyor speed to an exit of the cooling conveyor, wherein the bag bodies receive the adhesive while being conveyed on the transfer conveyor;

• wherein the transfer speed is higher than the cooling conveyor speed, wherein the cooling conveyor has a cooling surface, which faces the surface of the bag bodies provided with the adhesive after the bag bodies have been conveyed from the transfer conveyor, wherein the cooling conveyor comprises a cooling drum having a shell surface which forms the cooling surface, the adhesive on the surface of the bag bodies is configured to have a dwell time on the cooling conveyor as the adhesive on the surface of the bag bodies is cooled on the cooling surface such that the adhesive on the surface of the bag bodies is no longer sticky at the exit of the cooling conveyor when the bag bodies leave the cooling conveyor, and wherein both the transfer conveyor and the cooling conveyor are configured to convey the bag bodies in a direction of the longitudinal axes of the bag bodies.
