A method of testing a functional unit includes an optical sensor system (28) for detecting an optical signal from at least a part of a moving material web (14), a data processing system (36) for valuating the optical signals, and a display (38) displaying a state of the material web (14) and arranged in a sensitive range (30) of the sensor system (28).

An electrode supply unit corrects an electrode target position based on a positional displacement amount of a first separator material, a first offset amount which is an actual positional displacement amount between the first separator material and an electrode when the first separator material is supplied in a manner that a positional displacement is not generated, and a movement amount in a lateral direction when an electrode supply region moves from a first position T1 to a second position T2 The electrode supply unit then supplies the electrode to the first separator material. A joining head corrects a joining target position based on a positional displacement amount of the electrode, a second offset amount which is an actual positional displacement amount which occurs when positions of the electrode and the joining head are adjusted so as not to cause positional displacement, and a movement amount in the lateral direction when the electrode supply region moves from the third position T3 to the fourth position T4. The joining head then joins the separator materials.

A material aligning device having a plurality of sine waves, wherein the sine waves can be in the form of protrusions repeating along an outer surface of a roller. The material aligning device provides an oscillation to the material sheet moving on it to cancel its vibrations, which allows for faster and improved alignment while printing, web converting, and during other similar processes. The material aligning device also relieves the high amount of tension typically necessary for the printing, converting, and other similar material processing using machines. The reduction in tension also reduces the likelihood of the material sheet being overly stretched or for it to rip.

A roller (1) is used for guiding and/or width stretching of a running material web (2). The roller (1) has a supporting body (3), on the outside of which receptacles (4) for axially displaceably held battens (5) are provided. These grasp the material web (2). In order to improve the functionality of this roller (1), at least one undercut groove (6) is formed on the supporting body (3) between at least two of the battens (5). This undercut groove (6) can receive at least one functional component (7).

Apparatus and methods are provided for automatic edge positioning and guiding of a moving web, such as a textile fabric or carpet, onto a conveyor system comprising manufacturing operations such as sewing, for example. More in particular an apparatus is provided including mechanics, optics and control for steering and positioning the side edges of the moving web in order to correct for misalignment, and hence sewing can occur appropriately.
