A film tensioning and steering system can be configured to extract a film from a film source. One or more film characteristics can require that the film tensioning and steering system be isolated from the film source so that a film tension can be maintained within the film tensioning and steering system. A first drive roller pair and a second drive roller pair can be configured to secure the film and enable a dampening roller to maintain the film tension between the first drive roller pair and the second drive roller pair. Additionally, the dampening roller can store an amount of the film as a film buffer. Accordingly, the film tensioning and steering system can maintain the film tension such that a steering system can align the film before the first drive roller pair provides the film at a proper alignment to a downstream system.

The present invention relates to a method of guiding a web with a shifting path of the web to a substantially constant centration point. It comprises the steps of providing a web with a shifting path of the web from a source of the web, measuring upstream of said centration point, the position and/or orientation of said web by a sensor arrangement, and guiding said web to said centration point in accordance to the measurement results. The present invention advantageously relates to operations in the manufacturing of absorbent articles such as unwinding web rolls that are wound in a shifted manner, in particular spirally wound web rolls, and removing web from containers of loose web material. The invention also relates to a device for the execution of the method.

A roller for transporting a flexible substrate is described. The roller includes a main body having a plurality of gas supply slits provided in an outer surface of the main body. The plurality of gas supply slits extends in a direction of a central rotation axis of the roller. Further, the roller includes a sleeve provided circumferentially around and in contact with the main body. The sleeve has a plurality of gas outlets extending in a radial direction (R) and being provided above the plurality of gas supply slits.

A system and method is described for marking materials in rolled form so as to overcome the problem of locating the starting point/location of said rolled material after a portion of said rolled material has been removed from the roll of said rolled material by distinguishing/pinpointing the location of every actual tear. The system and method overcomes personal frustration, wasted material and wasted time.

A manufacturing method for a band-shaped glass includes a forming step, which forms a band-shaped glass, an annealing step, which performs an annealing treatment on the band-shaped glass, a cooling step, which cools the annealed band-shaped glass, a direction-changing step, which changes a feeding direction of the cooled band-shaped glass from a longitudinal direction to a horizontal direction, and a horizontal conveying step, which conveys the band-shaped glass in the horizontal direction while supporting the band-shaped glass at a horizontal conveyance part. In the horizontal conveying step, the band-shaped glass is conveyed in the horizontal direction while a first propulsion for driving the conveyance in the horizontal direction is provided at both sides in the width direction of the band-shaped glass by the horizontal conveyance part, the first propulsion being larger than a second propulsion provided at a center in the width direction of the band-shaped glass.
