A processing system and a device manufacturing method that can perform manufacturing of an electronic device without stopping the entire manufacturing system, even when the processing state actually implemented on a sheet substrate by a processing device differs from the target processing state. A processing system for sequentially conveying a long, flexible sheet substrate along a length direction to each of a first through a third processing device to form a predetermined pattern on the sheet substrate, wherein the first through the third processing devices implement a predetermined process relating to the sheet substrate according to setting conditions set to each processing device, and when at least one from among the states of the actual processing implemented on the sheet substrate by each of the first through the third processing devices exhibits a processing error relative to a target processing state, changes other setting conditions, separate from the setting conditions exhibiting the processing error, according to the processing error.

A packaging machine comprises a conveying device for advancing a web along a web advancement path at least to a tube forming station where the web is formed into a tube and for advancing the tube along a tube advancement path, a tube forming and sealing device configured to form and to longitudinally seal the tube, a tensioning device upstream of the tube forming station and configured to control the tension of the tube and a control unit configured to control packaging machine operation. The tensioning device comprises a main drive roller rotatable around a main rotation axis and a main drive motor configured to actuate rotation of the main drive roller around the main rotation axis. The control unit is configured to control the main drive motor such that angular speed and/or angular acceleration of the main drive roller is cyclically varied to control the tension of the tube.
