发明名称 Encapsulating laminator
摘要 The apparatus and method employ upper and lower laminating films, having opposed layers of heat activated adhesive. The laminating films are brought together at the surface of an infeed roller which is positioned in front of two opposed heated laminating rollers. The laminating films are brought together at the infeed roller at such angles that an infeed shelf is formed and such that an article may be fed between the upper and lower films as they pass about the infeed roller. The article being laminated may be adjusted until the article has progressed into the nip between the laminating rollers.
