VERFAHREN UND VORRICHTUNG ZUR ETIKETTIERUNG VON BEHÄLTERN MIT DURCH PRESSLUFT UNTERSTÜTZTEM TRANSFER DER ETIKETTEN

摘要

A method and apparatus for labeling containers allows labeling of containers by wrap around labeling without applying an adhesive on the leading edge of the label. Labels are held on a label drum and moved into a label applying position while containers are fed into the label applying position. Air is blown from a first position on the label drum onto the leading edge of the label at an angle to the label drum surface and in a direction backward along the label from the leading edge to force the leading edge of the label against the container, while also minimizing the laminar flow of air under the label. After the leading edge of the label has engaged the container, air is blown from a second position on the label drum spaced from the first position onto the label and container at an angle to the label drum surface to maintain a laminar flow of air over the label and maintain the label tight against the container during container rotation. The leading edge is maintained on the container by wet adhesion or by air which is blown onto the label and container from first and second angled positions on the side opposite the label drum. Air can also be blown from a third position on the label drum spaced from the first and second positions onto the leading edge of the label after the container has rotated almost 360 degrees to maintain the label tight against the container during the final part of the wrapping process.
