Abstract
A turret winder for winding web material on spindle-supported cores has a turret which is moveable into three indexing positions, one of which is a web transfer, cutting and winding station, and another of which is a winding completion station. Frames adjacent to the turret support carriages which support a secondary lay-on roll. The carriages include a primary carriage which is moveable vertically with respect to the turret and a lay-on roll carriage which is moveable horizontally with respect to the primary carriage. The lay-on roll carriage has an arm which is engaged by the turret during movement of the spindle between the above two positions so that arcuate movement of the spindle is translated to movement of the lay-on roll carriage in such a manner that the lay-on roll accurately follows the movement as the building roll moves to the winding completion station.
