Abstract
Improved apparatus and methods of operating turn-up apparatus on a paper machine to improve performance of a paper machine turn-up process via the inclusion of the ability to vary an amount of tension on a paperband being deployed during a turn-up procedure. A cross track may have a first internal slot for the paperband to move upon and a second slot to support a first adjustable track top holder. The first adjustable track top holder holds a first top tension band in a fixed position relative to an underlying first bottom tension band.
Claims20
An apparatus for deploying a paperband for a paper machine turn-up operation, the apparatus comprising:
- a first removable tensioner comprising a securing portion and a paperband engagement portion connected by a connection medium;
- a cross track, comprising a first internal slot for the paperband to move upon, and a retaining pocket to removably attach the securing portion of the first removable tensioner above the first internal slot, and position the paperband engagement portion of the first removable tensioner across an opening between the paperband and a web spool such that a surface of the paperband engagement portion of the first removable tensioner contacts the paperband during the paper machine turn-up operation;
- and
- a paperband feeding device;
- wherein the paperband feeding device advances the paperband during at least an initial portion of a turn-up operation.
An apparatus for deploying a paperband for a paper machine turn-up operation, the apparatus comprising:
- a cross track, wherein the cross track comprises at least a first internal slot for the paperband to move upon and at least a second slot to support a first adjustable track top holder, wherein the first adjustable track top holder holds a first top tension band in a fixed position relative to an underlying first bottom tension band;
- the first top tension band, wherein the first top tension band lies across the cross track above a location for the paperband, and wherein the first top tension band interacts with the first bottom tension band;
- the first bottom tension band, wherein the first bottom tension band lies across the cross track above the location for the paperband and below the first top tension band, and wherein the first bottom tension band interacts and contacts the paperband when it is pulled out of the apparatus during the paper machine turn-up operation;
- a curve track, wherein the curve track holds the paperband at an angle to an axis of the cross track;
- and
- a paperband feeding device;
- wherein the paperband feeding device advances the paperband during at least an initial portion of a turn-up operation.
