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.

A paper winder includes a first winding core that is provided in a first arm turning centering on a rotating shaft and on which the paper should be wound, a first motor that drives the first winding core, a second winding core that is provided in a second arm turning centering on the rotating shaft and on which the paper should be wound next to the first winding core, and a controller that performs rotation control for the first motor and a second motor. In the rotation control, after, according to the turning of the second arm, completion of the winding of the paper by the first winding core and after a position of the second winding core has reached a position where the paper should be wound, during an operation of a traverse cutter that cuts the paper near the second winding core, when a torque value of the second motor is equal to or larger than a torque reference value, the controller switches a control mode of the second motor from speed control to torque control and perform tension correction control for adjusting the torque value of the second motor such that tension of the paper falls within a target range.

A thin metal strip winding method includes: a step of causing a thin metal strip to fly from a flight tube; a cutting and grasping step of cutting and grasping any portion of the thin metal strip flying from the flight tube; a thin metal strip connecting step of connecting the any portion of the thin metal strip cut and grasped in the cutting and grasping step and a leader as a ribbon, the leader being a to-be-connected portion of another thin metal strip remaining on a winding roll set on a winding roll rotation unit of a winder that winds up the thin metal strip; and a thin metal strip winding step of winding up the ribbon around the winding roll by causing the winding roll rotation unit to rotate.

A family of paper tape turn-up constructs for accomplishing automated paper web turnup in paper processing. Methods and apparatus to form the constructs are described. Methods and Apparatus to apply the constructs to paper production equipment are also described. In some examples, the paper tape turn-up construct includes a cover flap to protect an adhesive layer during initiation of the paper web turn up process.

A cover-flap transfer tape construct and associated applicators for paper web turn-up are disclosed. A zone-coated substrate carried on a linered web includes a top-side central web-grabbing adhesive band bounded by uncoated edge zones, and underside edge mounting adhesive bands separated by an uncoated middle zone. An applicator forms an out-of-plane raised profile across a central portion of the tape while maintaining planar side bands, using cooperating forming members (convex crest and complementary cavity) and manual or motorized feed. The formed length is cut to yield a discrete tape construct with the raised profile over the central adhesive and side bands aligned with mounting adhesives. The tape construct promotes reliable interception and transfer of a moving paper web during turn-up.

A roll transfer assembly for a web processing system includes a support beam configured to be mounted to a frame. The assembly includes a segmented roll assembly mounted to the support beam and includes a first and second end segments and a central segment positioned between the first and second end segments. The assembly includes a first transfer roll positioned between the first end segment and the central segment and a second transfer roll positioned between the second segment and the central segment. The assembly includes an actuation assembly that includes a first drive system configured to translationally move the first transfer roll and the second transfer roll. A second drive system is configured to move the roll transfer assembly relative to the frame.
