    摘要: This disclosure is concerned with enabling the use of multiple liquid adhesive nozzles principally to provide continuous uniform adhesive layers, particularly in relatively small items such as cigarette filter tips or the like, wherein a critically oriented adhesive shear surface adjacent the nozzles causes the plurality of adhesive beads simultaneously deposited by the nozzles to merge into a full, continuous, uniform coating, and with additional control features provided to control the degree of merger from separate adjacent beads to uniform merged coating.

    摘要: Uniformity of hot melt coatings on thermally sensitive plastic and other webs is maintained by use of a silicone or other rubber-like web back-up roll the dimensional stability of which is maintained during hot melt coating of the webs by a heat-conducting idler roll directly contacting the back-up roll temperature and a heat transfer source for temperature deficiencies on the silicone roll surface, aiding constant nozzle-to-web spacing irrespective of temperature variations and line speeds. Provision is also made for the introduction of chilling, if required.
