Abstract: This invention proposes a new, improved method and apparatus for applying web segments to a traveling web. These web segments, sometimes called ears or wings, may be asymmetrical or otherwise incompatible with the usual slip-and-cut method. The asymmetrical shape may have differing web tensions which can cause the web segments to be improperly engaged with the vacuum holes on an anvil roll. The present invention utilizes both circumferential rows of vacuum holes and an additional pattern of ear retaining vacuum holes. The circumferential rows of vacuum holes are activated consecutively by vacuum commutation, however, the pattern of ear retaining vacuum holes are activated simultaneously to counter the effects of differing web tensions on the ear portions.

Abstract: We have designed a machine for office use called the Electric Paper Reinforcer/Hole Puncher (EPRHP) to protect the printed document. EPRHP is an electric powered device that can automatically apply a clear, ultra thin layer of plastic film on the edge of printed documents to reinforce them, and then punch 3 holes within the plastic film area on these documents. As a result, these 3 holes will be reinforced and prevent the documents from being torn by the rings of the binder. EPRHP can be further used to reinforce large sized printed drawings by applying the plastic film on the edge of drawings. The EPRHP is a portable machine and can be placed on an office desk. EPRHP can turn a document printed on a piece of regular bond paper into a durable document, without deforming the paper appearance or creating any winkles on the paper.
