  • Patent number: 10555905
    Abstract: A retaining system for a solenoid assembly of a liquid adhesive dispensing system includes a quick-release mechanism configured to secure the solenoid assembly in place. The quick-release mechanism engages an air tube of the solenoid and thereby secures the entire solenoid assembly to a manifold. The quick-release mechanism can release the solenoid, facilitating easy removal of the entire solenoid assembly, by a simple turning, pushing, or pulling action on the quick-release mechanism. The released solenoid can then be removed and replaced, thereby minimizing downtime caused due to the replacement of a faulty solenoid.
    Type: Grant

  • Patent number: 9884331
    Abstract: A bellow seal of a fluid dispensing system is disclosed. The bellow seal having a generally circular cross section includes a first end having a first diameter. The bellow seal further includes a second end having a second diameter that is smaller than the first diameter of the first end. The bellow seal further includes a contoured external surface extending between the first end and the second end. The external surface includes a cylindrical portion extending from the first end, an undulating portion, (which includes a convex portion extending from the cylindrical portion and a concave portion extending from the convex portion), and a tapered portion extending from the concave portion to the second end. The bellow seal further includes a flexible region defined between a first point located on the cylindrical portion and a second point located on the concave portion.

  • Publication number: 20160370129
    Abstract: A cover assembly for a liquid adhesive applicator protects a user from burns in case the applicator is touched and provides additional insulation for the applicator, thereby saving energy. The cover includes a first side panel and a second side panel connected to each other by posts extending through and around the applicator. A front panel is secured between the first side panel and the second side panel. A first insulating sheet may be disposed between the first side panel and a first side of the applicator to provide further insulation. Similarly, a second insulating sheet may be disposed between the second side panel and a second side of the applicator.
