Abstract: A web, such as a paper web, is reeled onto a core tube supported by first and second carrying rolls with a topside pressing roll pressing down on the web roll as it is being formed. The completed web roll is removed from the carrying rolls by at least two lowering rolls which are lifted along a path into engagement with the completed web roll, the lowering rolls contacting the web roll after being rotatably accelerated to have an appropriate surface speed. Substantially simultaneously with the completed web roll being lowered, a new core tube is inserted in the throat between the first and second carrying rolls. The web is cut, preferably without interrupting its movement, and the newly cut end of the web is affixed to the newly positioned core tube.
Abstract: A method for punching disc-like lock parts from a metal band or the like and for combining them to form lock mechanism units determining different lock combinations or the like. The punching of the parts to their final form takes place in a series of punching actions carried out by different punching units. Punching of parts having different details is carried out by having the pattern of the series changed for each punching stroke. In a final phase, the punched lock parts are separated from the band and collected in an order determined by a pre-selected combination code.
