发明名称 Intermittent adhesive applicator
摘要 An applicator 15 deposits a solvent-carried adhesive intermittently along a moving strip 10. A sump 26 is arranged below strip 10 to contain a quantity of the solvent 27, and an adhesive wheel 16 rotates with its lower region immersed in the solvent. Adhesive wheel 16 has a continuous periphery on which adhesive is continuously applied, and an applicator wheel 17 rotates against the adhesive wheel and the bottom of the strip above the sump. Applicator wheel 17 a as an intermittent peripheral surface 18 that receives adhesive from the adhesive wheel and applies it in an intermittent pattern to the bottom of the moving strip. The sump, the adhesive wheel, the applicator wheel, and the region of contact between the applicator wheel and the strip are enclosed to retain a substantially saturated solvent vapor atmosphere within the enclosure 25 to inhibit the evaporation of solvent from the adhesive.
