An apparatus for automatically mounting rolls of a web material on a mill roll stand first moves a web roll on a roller conveyor in an axial direction and then in a lateral direction toward roll supports. The web roll is then automatically aligned with the roll supports by moving it vertically or turning the roll supports.

An apparatus for automatically mounting rolls of a web material on a mill roll stand first moves a web roll on a roller conveyor then in an axial direction and next in a lateral direction toward roll then automatically supports. The web roll is aligned with the roll supports by moving it vertically or turning the roll supports.

An improved process and apparatus for splicing a new web to a running web are proposed. The old web is cut off just behind the spliced point. Therefore, no tail is left on the web spliced. The running web is nipped at two points between two pairs of rolls. Because it is tight between the two points, a clear cut is possible with a single cutting blade.

Method and apparatus for splicing web

A mill roll stand for supporting at least one roll of paper or similar web-like material. The stand has a pair of endless members arranged with a spacing therebetween, at least one pair of bases mounted on the endless members so as to be opposed to each other, at least one pair of center shafts supported in the bases so as to be laterally slidable into and out of the center hole in the roll to be supported to hold the roll, a drive for driving the endless members in a synchronous manner, and a guide for guiding at least part of the endless members so that they will run in a predetermined route even under the weight of the web rolls.
