ABSTRACT:
A method and apparatus for handling logs of convolutely wound webs which includes providing a rewinder-tail sealer wherein a glue stripe is applied to a predetermined circumferential location on a partially unwound log and the log rewound by rolling on itself toward and into a pair of spaced-apart rollers, providing a path from the roller pair to log receiver wherein logs sequentially roll in the path, the path having fixed dimensions, operating the rewinder-tail sealer to develop logs of a first nominal diameter to enable the roller pair to controllably rotate each log for positioning the glue stripe at a first angular orientation, which in combination with the fixed dimensioned path enables each log to be received in the receiver with its glue stripe in a second angular orientation, changing the operation of the rewinder to develop logs of a second nominal diameter, and by correlating the second nominal diameter with the fixed dimensioned path to enable each second nominal diameter log to be received in said receiver with its glue stripe in the second angular orientation and adjusting the spacing between the roller pair to be slightly less than the second nominal diameter.
