Abstract
A web transfer system includes a first winder with a first core thereon and a second winder with a second core thereon. The web transfer system includes a roll changer carriage that is moveably mounted on a track and communicates with a carriage actuator. A linkage is pivotally mounted to the roll changer carriage and is movable between a first and second roll transfer positions. The linkage includes a lay-on roll and an auxiliary arm. The auxiliary arm is pivotable between a retracted and extended position. The auxiliary idler is rotatably mounted to the auxiliary arm. The lay-on roll and the auxiliary idler roll transfer a web from the first core to the second core.
Claims19
A web transfer system, comprising:
- a first winder fixedly mounted to a foundation, the first winder having a first spindle rotatable about a first spindle axis;
- a second winder fixedly mounted to the foundation and being spaced apart from the first winder, the second winder having a second spindle rotatable about a second spindle axis;
- a roll changer carriage moveably mounted on a track;
- a carriage actuator configured to actuate the roll changer carriage;
- a linkage pivotally mounted to the roll changer carriage about a linkage axis, the linkage being movable between a first roll transfer position and a second roll transfer position;
- a first lay-on roll rotatably mounted to the linkage about a first axis of rotation;
- a first auxiliary arm pivotally mounted about the first axis of rotation and being pivotable between a first retracted position and a first extended position;
- and
- a first auxiliary idler roll rotatably mounted on a first distal end of the first auxiliary arm,
- wherein the first lay-on roll and the first auxiliary idler roll are configured to transfer a web that is wound around a first core on the first spindle to a second core on the second spindle;
- a second lay-on roll rotatably mounted to the linkage about a second axis of rotation;
- a second auxiliary arm pivotally mounted about the second axis of rotation so as to be pivotable between a second retracted position and a second extended position;
- and
- a second auxiliary idler roll rotatably mounted on a second distal end of the second auxiliary arm.
