摘要： A method and apparatus for automatically performing work operations, such as the punching of apertures, on moving web materials. The apparatus includes a chassis that is mounted for limited movement in the direction of web travel. The chassis includes a clamping plate and a base plate which are selectively brought into clamping engagement with the web, which enables the chassis to be moved along with the web. Subsequently, a tool is drawn into engagement with the web to perform the work operation. Upon completion of the work operation, the tool is removed from the vicinity of the web, the web is released by the chassis clamping and base plates, and the chassis is returned to its original position.
