Abstract
The book cover applicator is suitable for use in applying covers to multiple sheet fillers which have been secured together along the spine by a hotmelt adhesive. The applicator includes clamps for securing the filler and cover at a cover application station, a heater bar for applying heat to melt the hotmelt adhesive, and a blower for cooling the melted hotmelt adhesive to ambient temperature. The hotmelt adhesive provides a strong, flexible bond between the filler spine and the cover.
