Toilet-tissue winders are able to change over at running speed, while paper and board winders need to stop the winding process in order to cut the sheet and glue the paper on to a new wind-up core. Top-line winders introduce the paper core through a maintenance pit downstairs, with web interruption time as low as 15 seconds.
Even if the demands for low tolerances of the wire and the winding space had to be observed with correspondingly high technical effort, there would still remain the problem that the wire guiding on the machine side has to follow the previously described winding design also at high winding speeds.

The lockstitch sewing machine, invented and developed in the 18th and 19th centuries, [10] [11] forms a stitch with two threads: one passed through a needle and another from a bobbin. Each thread stays on the same side of the material being sewn, interlacing with the other thread at each needle hole thanks to the machine's movement. [12]
The first machine to combine all the disparate elements of the previous half-century of innovation into the modern sewing machine was the device built by English inventor John Fisher in 1844, a little earlier than the very similar machines built by Isaac Merritt Singer in 1851, and the lesser known Elias Howe, in 1845. However, due to the ...
