Qualitatively selective retractable peel plate for labeling

摘要

A peel plate assembly functions in a normal position of the plate 101 being extended for the purposes of peeling adhesive labels from a supply web and directing them toward containers (120), but can be retracted selectively when a label is identified as incorrect or faulty, thereby leaving faulty or incorrect labels on the label supply web at least until they are removed from the active site of label application. When the peel plate 101 and its supporting block 111 are retracted from the normal position shown, the web passes around a roller which has no sharp edge to cause peeling. Defective labels are detected by a scanner connected to a central processing unit.
