| This patent provides an apparatus and a method of tensioning a flat web of material to be conveyed, of the kind set forth in the opening part of this specification, which permits tensioning of When conveying flat webs of material, a problem which frequently arises is that, within an item of equipment, a machine and so forth, after a conveying operation, the web of material must be positioned precisely with respect to a processing station such as for example a printing station or a stamping station. In order to occupy the precise position at any time, the web of material must be held virtually always taut or tensioned. In addition, it is frequently not sufficient for the web of material merely to be driven in the direction of advance movement, but the web of material must also be pulled back in the direction opposite to the direction of advance movement, either because the web of material has been advanced too far as a positioning error, or because the web of material has been pushed beyond a desired position, as a result of a processing step. Both when the web of material is being advanced and also when it is being pulled back, the demand for precise positioning makes it necessary for the web of material to be held in a tensioned condition or taut. This patent concerns an apparatus and a method of tensioning a flat web of material to be conveyed, in particular in a printing and dispensing device for labels, which includes: a drive for advancing and retracting the flat web of material, and at least one advance unit and at least one braking unit having a braking roller which are in contact with the web of material and which are drivable by the drive means. It is further provided that the drive has a drive motor that is drivingly connected to the advance unit and the braking unit and that, in a conveyor operation in the advance direction of the web of material, the braking roller of the braking unit is uncoupled from the drive motor. |
