METHOD AND WELDING DEVICE FOR CONNECTING SHEETS OF MATERIAL
First Claim
1. A method for connecting material webs arranged with overlapping edges in which an automatic welder which has a carriage, a drive unit and a welding device, is guided along the overlapping zone of the material webs to be connected, whereby the edges to be connected are connected to each other by the welding device, wherein a temporary guide marking moving with the carriage along the edge of the overlapping material web and prescribing the movement track of the automatic welder is generated on the overlapped material web by means of a marking device arranged on the automatic welder, and the guide marking is detected during the movement of the automatic welder by a sensor device whereupon a control signal is produced for a display unit and/or for a steering unit and the automatic welder is always movable precisely along the movement track prescribed by the generated guide marking by means of the control signal.

Abstract
The invention relates to a method for connecting material webs disposed with overlapping edges, wherein an automatic welding machine having a driven chassis and a drive unit disposed thereon and a welding unit is guided along the overlap zone of the material webs to be connected, such that the carried welding unit connects the edges to be connected to one another. The invention further relates to an automatic welding machine for performing the method. The invention proposes that a temporary guide marking moving along with the chassis be generated along the edge of the overlapping material web by means of a marking unit disposed on the chassis, said guide marking always extending parallel to the edge and prescribing the path of the automatic welding machine on the overlapping material web and that the guide marking be detected by means of a sensor device during the movement of the automatic welding machine, wherein a control signal is generated for a display unit and/or the drive unit and the chassis is movable along the guide marking by means of the control signal.

- 6. An automatic welder for connecting material webs arranged with overlapping edges, having a carriage, a drive unit and a welding device, the carriage being guidable along the overlapping zone of the material webs to be connected and the edges to be connected being connectable by means of the welding device, characterised by a marking device by means of which a temporary guide marking, moving together with the carriage and prescribing the movement track of the automatic welder can be generated on the overlapped material web along the edge of the overlapping material web, and a sensor device with which the guide marking can be detected during the movement of the automatic welder, so that a control signal for a display unit and/or for a steering unit can be produced, with which the automatic welder is always movable precisely along the movement track prescribed by the guide marking.
