Abstract: Method and arrangement for winding a web wherein a roll being formed is supported in an axial direction of the roll by first and second support members placed at sides of the roll. The shape of the end of the roll being formed is measured indirectly or directly, and the relative positions of the support members in relation to one another are regulated based on the measurement. As indirect measurement, it is possible to measure forces in the axial direction of the roll, and as direct measurement, it is possible to measure the side line of a roll end directly by contact measurement or contact-free measurement. Based on the measurements, the relative positions of the support members in relation to one another are regulated such that any defects in the shape at the ends of the roll being formed can be prevented.

Abstract: To manufacture a film unit, a filmstrip is advanced out of a cartridge shell by rotating a spool of the cartridge shell through a spool drive shaft. The spool drive shaft stops when the filmstrip is advanced a predetermined length out of the cartridge shell. A rotational position of the spool at the stop of the spool drive shaft is detected based on a rotational position of the spool drive shaft. The cartridge shell is disengaged from the spool drive shaft while the rotational position of the spool and the advanced length of the filmstrip are maintained unchanged. The spool of the cartridge shell is engaged with a film supply shaft, after adjusting a rotational position of the film supply shaft to the rotational position of the spool, while the leading end of the filmstrip is secured to a winding shaft. The filmstrip is wound into a roll by rotating the winding shaft.

As the web is severed the second carriage positions its core to become the winding core and the first carriage moves away to off-load the full core, then, returns to a ready position with a fresh core.

Abstract: A woven cloth inspecting apparatus eliminates the influences of disturbances such as illuminating light and fly. At least two photoreceptor elements are arranged in the direction of the weft yarn of woven cloth. The photoreceptor elements detect different area of the woven cloth and they apply current signals to two respective current-to-voltage converters which convert the current signals into voltage signals which are fed to a difference calculating circuit. The difference calculating circuit calculates the difference between the values of the voltage signals received from the two current-to-voltage converters and supplies the obtained difference signal to a comparator which compares the received difference signal with a reference value preset by two reference value setting circuits. Exceeding the reference value is indicative of a defect in the warp. Alternatively the photoreceptor elements are arranged in the warp direction and detect defects in the weft.

Abstract: Film edges 9, 9 of a film web 1 are sensed with sensor heads 4,4. The sensor heads 4, 4 can be motor-adjusted transversely to the longitudinal direction of the film web 1. By virtue of the displacement, signals are produced which are proportional to the displacement and which activates servo valves 8, 8. These servo valves are connected to positioning cylinders 10, 10 which are in turn connected to chain-path deflector heads 6, 6. The signals of the servo valves activate the adjustment cylinders, which then adjust the chain-path deflector heads and thus drive them in response to movement of the film edges. By virtue of the adjustment of the chain-path deflector heads, the paths of the clip chains 14, 14 are also adjusted, resulting in a variation of the grasping depths of the film strip held firmly by the clips. This brings about an oscillating movement of the film web after the feed-in into the transverse stretching frame 16.
