Winder assembly and method of use thereof

A method for changing cores on a winder assembly, comprising:

• providing a turret assembly including a first core and at least a second core mounted for rotation on the turret assembly, the first core having a web of sheet-type work material winding there around;
• providing a lay-on roll assembly moveable between a retracted and an engaged position, the lay-on roll assembly having at least one roller forming part thereof, the lay-on roll assembly being in the engaged position with the roller rotatably engaged with the work material winding onto the first core forming a first nip between the roller and the first core;
• causing a first actuator, in response to commands issued from a controller, to operate to move the lay-on roll assembly to the retracted position wherein the roller is tilted off of and away from the work material wound onto the first core;
• causing the turret assembly, in response to commands issued from the controller, to index the first core onto a roll removal position and the second core into a winding position;
• causing the first actuator, in response to commands issued from a controller, to operate to move the lay-on roll assembly to the engaged position with the roller rotatably engaged with the work material winding onto the first core;
• cutting the work material to separate the work material from the roll of work material wound onto the first core, thereby creating a work material edge;
• providing a transfer roll assembly moveable between a retracted and an operating position, the transfer roll assembly having at least one roller forming part thereof;
• and
• actuating a second actuator, in response to commands issued from the controller, thereby causing the transfer roll assembly to move from the retracted to the operating position so that the roller forming part of the transfer roll assembly rotatably engages the second core forming a second nip between the roller and the second core;
• providing a transfer roll assembly rail having a rail end pivotally extending there from and being moveable between a retracted and an operating position, the at least one roller being coupled for rotation to the rail end, the roller being movable between a retracted and an engaged position;
• and
• actuating a third actuator, in response to commands issued from the controller, thereby causing the rail end and the roller to move from the retracted to the operating position so that the roller forming part of the transfer roll assembly rotatably engages the second core forming a second nip between the roller and the second core.
