摘要:
A method and apparatus (20) for intermittently cutting a moving target web (26) includes rotating a knife roll (32) having at least one knife member (44) to provide an operative knife-member speed, and rotating an anvil roll (34) having at least one anvil member (46) to provide an operative anvil-member speed. The knife roll and anvil roll have been positioned to provide an operative nip region (30) therebetween, and a substantially continuous target web (26) has been moved at a selected web speed through the nip region. A rotational positioning of the knife member has been coordinated with a rotational positioning of its cooperating anvil member to provide an operative, cutting engagement between the knife member and its cooperating anvil member, thereby cutting the moving web at cut locations which are intermittently spaced along a machine-direction (22) of the target web.

The invention relates to methods and an apparatus useful to installing and removing endless belts in a conveyor system and more preferably continuous fabrics, belts, felts and webs used in the papermaking process. According to the present invention a pair of guide rolls to move a first continuous fabric from a first fabric position to a second fabric position and a second fabric from the second fabric position to the first fabric position, passing the fabrics over one another as the position of the fabrics are exchanged. The movement of the first and second fabrics may be done at the same time so as to further enhance the efficiency of changing fabrics.

The present disclosure relates to creped tissue webs that demonstrate low surface-roughness and high sheet bulk. The present disclosure relates to a creped, single ply tissue web having a single wire probe mean deviation of MIU (MMD) of less than about 0.040 and a sheet bulk of greater than about 12 cc/g. The present disclosure also relates to a creped, multi-ply tissue web having a single wire probe mean deviation of MUI (MMD) of less than about 0.035 and a sheet bulk of greater than about 10 cc/g.
