Abstract (en)
[origin: EP0839584A2] An adhesive or other viscous liquid applicator apparatus utilizes a cylindrical glue roll (45) and a reverse acting notched metering or doctor blade (47) which forms, from an initial liquid layer on the roll, a series of laterally spaced liquid beads of metered size. The beads are subsequently spread to form a liquid layer for transfer to a web or other surface by a flexible spreader tongue (51). A glue film control system and glue film width control are also disclosed.
