Winder with constant packing roll

A turret winder comprising:

• a rotatable turret assembly having a first core and a second core supported thereby, the turret being rotatable so that the first core can be positioned at a first location while the second core is positioned at a different second location, wherein a web material can be wound onto either of the first and second cores at either of the first and second locations;
• a pack roll assembly associated with each of the first and second cores, the pack roll assembly including one pack roll that is movable into contact with one core with a winding roll thereon so that a web leading onto the one core from a web source contacts the associated pack roll at or prior to winding thereof on the winding roll for excluding entrapped air prior to forming of convolutions on the roll in a winding position at either of the first and second locations and locations therebetween, and wherein each of the first and second cores is unloaded at the first location after the winding is completed thereon and a new core is loaded at the same first location, while the other of the first and second cores is continuously winding at the second location, the turret and pack roll assemblies being configured to permit the new core to be rotated to the second location, while the core with the winding roll thereon is rotated to perform unloading at the first location without any interruption of winding thereon, wherein each pack roll assembly including the respective pack roll and a mechanism for moving and maintaining the pack roll in contact with the respective one core with the winding roll thereon being independently rotatable relative to the respective one core with the winding roll and relative to the other pack roll assembly, wherein each of the pack roll assemblies includes a pack roll support member on which a carriage travels in a controlled movement, the pack roll support member having an opening formed therethrough that receives one respective spindle bearing housing to permit the pack roll support member to be rotatable about the spindle bearing housing.
