Abstract
Precision cutting means adapted for use in cutting, e.g., small holes along a continuous web. The novel apparatus by which the process of the invention is to be carried out comprises opposed cutting means, mounted on either side of a path through which a web to be processed is moved. Each cuts only part way through the web, the cuts from each side being in exact register and leaving a blank which is secure until it is removed by positive mechanical action.
