A method of manufacturing fluted rolls, in particular for corrugating machines, comprises the steps of providing a fluted-roll blank which has a central longitudinal axis and a longitudinal direction that is parallel thereto and a surface; providing a grinding device for grinding, on the surface, flutings that run in the longitudinal direction, with the flutings comprising heads and roots that are parallel to each other and are regularly and alternately distributed along the circumference of the surface; and grinding fluting heads on the surface by means of the grinding device, with the fluting heads having the same cross-sectional curvature in the longitudinal direction.

Fluted roll and method for the manufacture thereof

The invention pertains to a device for splicing webs, in particular, paper webs for manufacturing corrugated cardboard, with a splicing unit ( ) for preparing and splicing the rear end of a nearly empty active roll ( ) to the front end of a web ( ) to be spliced, and with the splicing unit ( ) containing one respective intake ( ) for the active web ( ) and for the web ( ) to be spliced. The device also contains a web unrolling device ( ) that serves for accommodating several web rolls ( ), with the web unrolling device ( ) being constructed in such a way that it is able to accommodate at least three web rolls ( ) such that a first web of the three webs delivered from the web rolls ( ) can serve as the active web ( ), a second web of the three webs ( ) can serve as the web ( ) to be spliced to the active web and the third web roll ( ) can be simultaneously exchanged and/or the web in question can be prepared for the next splicing process.

Corrugated cardboard manufacturing process

A machine for the production of a single-face lined web of corrugated board comprises a pressing device for pressing a liner web on a paper web provided with a corrugation. This pressing device comprises a vapor permeable pressing belt which consists of a fabric of metal with warp threads and weft threads. The warp threads arc provided in groups of three warp threads at a time, the distance of two neighboring groups of warp threads being smaller than the width of each group of warp threads. Preferably, the material of the weft threads is softer than the material of the warp threads, the weft threads having notches, in each of which a warp thread is disposed.

An apparatus for the manufacture of sheets of corrugated web of variable size comprises a margin cutting arrangement, which is disposed--in the conveying direction--downstream of, and separated from, longitudinal cutting arrangements and which is provided with cutting devices for cutting margins, which are permanently in engagement with the web of corrugated board. In the case of changes of format width accompanied by changes of the width of the margins to be cut off, this makes it possible that the latter can be cut continuously, which helps avoid malfunction.
