ROLLER TRANSFER APPLICATION METHOD AND APPLICATION DEVICE FOR HOT-MELT ADHESIVE

摘要

In a roller transfer application method for a hot-melt adhesive, a coater head having a slot in a direction towards an axis center of a pattern roller is provided to face a pattern surface of the pattern roller; and by supplying the hot-melt adhesive, which is supplied from a hot-melt adhesive supply device, in a thin-film state to a pattern top surface of the pattern roller, thin-film hot-melt adhesive is thus only supplied to the top surfaces of protrusions of the pattern roller. By opening an on-off-type hot-melt adhesive supply control valve, which is attached to the coater head, at a timing that an adhesive opening (the slot) on the bottom surface of the coater head faces application zones on the pattern surface of the pattern roller, the hot-melt adhesive is supplied only to the top surfaces of the pattern roller protrusions.

主权项

1. A roller transfer application method for a hot-melt adhesive, including a step of transferring a hot-melt adhesive applied to a protrusion of a pattern roll, from a protrusion surface of the pattern roll to a surface of an application substrate,
wherein the hot-melt adhesive in a thin film state is fed only to the protrusion surface of the pattern roll by providing a coater head having a slot groove in an axial direction of the pattern roll to face a pattern face of the pattern roll, and feeding the hot-melt adhesive fed from a hot-melt adhesive feeder, in a thin film state, to a pattern surface of the pattern roll.
