Further, resilient force is stored in a second spring by tension produced when the ribbon is fed from the ribbon feed roller. The ribbon tends to slacken when the sheet is back-fed, such slackening ribbon is rewound by reversely rotating the ribbon feed roller by the stored resilient force.

Abstract: In a level control method of controlling levels of a series of mutually joined materials when the materials pass through a catenary zone, whenever the joint travels a given length in the catenary zone, a plurality of optimum catenary curves are calculated with the position of the joint in the catenary zone as a parameter. Based upon a result of the calculation so obtained, a relationship indicative of the level of a material at the location of a catenary sensor is then calculated as a function of the position of the joint in the catenary zone. At this moment, the catenary sensor is used to detect the level of the material. Finally, the level of the material at the location of the catenary sensor is controlled with a value indicated by the above relationship being used as a target value. As a result, even when a joint between two adjoining materials having different unit weights passes through the catenary zone, the materials can travel in the catenary zone while the level is appropriately maintained.

Abstract: A guiding and braking unit for a material web which passes through a processing machine, such as a machine for the manufacture of packing containers. The unit comprises a roller adapted to a guide cylinder for the web. This roller is manufactured from a material with a high coefficient of friction. The roller is adapted so that it can be swivelled via an arm in a direction transverse to that of the material web to thus follow the material web when it is moved sideways, or axially in relation to the guide cylinder. Each sideways movement, however, because of the suspension of the roller, brings about a lifting of the roller which is continuously counteracted by the pressing of the roller against the cylinder. As a result, the roller is returned automatically to a central position and through friction, carries the material web with it to a central position in relation to the guide cylinder.
