Abstract

An apparatus and method for applying adhesive in a web converting machine is disclosed. In some embodiments, an adhesive application assembly is used to seal the tail of a rolled product against the rolled product. After being positioned in a location upon a roller, the rolled product is rotated and a sensor detects the location of the tail end, thereby establishing a reference for determining tail length in later operations. When the tail reaches a desired position, the adhesive application assembly applies adhesive to the tail and/or rolled product. In some embodiments, the adhesive assembly includes one or more adhesive sprayers with aperture members, and is self-cleaning. After the adhesive has been applied, the tail is wound upon the rolled product. In some embodiments, an adhesive application assembly is employed to apply adhesive to a core about which sheet material is to be wound.
