Abstract
Apparatuses and methods of forming sheets having different lengths are provided. The apparatuses and methods may also be used to form panel lengths of different values using a same processing roll. In some embodiments, the diameter of the roll need not change. In some embodiments, the spacing between adjacent rolls need not be changed when transitioning from one sheet length to another sheet length. In some embodiments, the processing roll includes an excess material receiving component that can be active or deactivated to switch between different sheet sizes.
Claims19
An apparatus for forming sheets of web material of different lengths, the apparatus comprising:
- a cutting arrangement for cutting a web of material into sheets at a cutting location, the cutting arrangement including a roll receiving the web of material on an outer periphery thereof and carrying the web of material past the cutting location, the roll rotating about a rotational axis, the roll having an excess material receiving component having a first mode and a second mode;
- wherein in the first mode, a first extent of material is accommodated by the excess material receiving component to form sheets of a first length;
- wherein in the second mode, a second extent of material is accommodated by the excess material receiving component to form sheets of a second length, the second extent of material being greater than the first extent of material;
- and
- wherein the roll rotates about the rotational axis through a first arc angle that is the same for forming the sheets of the first and second lengths.
