Claim 12:
13. An apparatus for deploying a paperband for a paper machine turn-up operation, the apparatus comprising:
a cross track comprising a first internal slot for the paperband to move upon and an attaching feature to affix a first apron to a surface proximate to the first internal slot;
the first apron, wherein the first apron lies across the surface above a location for the paperband, and wherein the first apron interacts and contacts the paperband when it is pulled out of the apparatus during the paper machine turn-up operation;
an apron tensioning device, wherein the apron tensioning device provides an additional force against at least an edge of a surface of the first apron, wherein the apron tensioning device comprises a bladder, wherein the bladder is molded to the first apron, and wherein the attaching feature comprises an apron holding slot along a length of the cross track, wherein the first apron comprises a portion of its body that fits within the apron holding slot, and wherein the bladder contacts at least a portion of the first apron and applies additional tension to the paperband when the paperband exits the cross track;
a curve track, wherein the curve track holds the paperband at an angle to an axis of the cross track;
a paperband feeding device; wherein the paperband feeding device advances the paperband during at least an initial portion of a turn-up operation;
a pair of bars, wherein the pair of bars has a length approximately equal to a length of a spool of a paper making machine, and wherein the pair of bars is positioned to be between the cross track and the spool of the paper making machine such that the paperband passes between the pair of bars as the paperband is drawn through a nip; and
wherein the pair of bars are symmetrically bent in different regions to adjust forces on the paperband as it interacts with at least one bar of the pair of bars.
