METHOD AND DEVICE OF APPLYING ADHESIVE TO PACKAGING MATERIAL

摘要

PROBLEM TO BE SOLVED: To apply an adhesive to areas of the adhesive to be applied to a packaging material so as to match a purpose by area.

SOLUTION: Transfer of the adhesive depends on the transfer speed of a material web (21) and other parameters while the adhesive, particularly a hot melt-type adhesive is applied to the material web (21) for blank. The pressure of the adhesive acting on the adhesive is controlled by a pressure control valve (37) connected with a central control unit (31) of the machine corresponding to the transfer of the material web, thereby the adhesive can be uniformly distributed.
