An apparatus (1) for controlling the unwinding of a web (2) wound on a core is disclosed. The apparatus (1) includes a turnbar (10), an actuator (20), a sensor (30), and a controller (70). The turnbar (10) includes a target location to receive the web (2). The actuator (20) is coupled to the turnbar (10) and includes an axis of movement (29). The sensor (30) measures transverse placement of the web (2) relative to the target location and transmits an input signal to the controller (70) when transverse placement of the web (2) differs from the target location. The controller (70) provides an output signal to the actuator (20 to move the turnbar (10) along the axis of movement (29) such that the web (2) maintains substantial alignment with the target location.

A circumferential location of a tail end of a log of convolutely wound web material is determined by rotating the log in a stationary position and a diameter of the log is sensed with a sensor at a plurality of times while rotating the log in the stationary position. A plurality of signals corresponding to the diameter of the log at the plurality of times are generated. The signals corresponding to the diameter of the log at the plurality of times a compared. A change in the signals corresponding to the diameter of the log at the plurality of times is detected and associated with the circumferential location of the tail end of the log.

A filament winding apparatus includes a bobbin driving unit, a winding device, and a tension applying device. A filament winding method using the filament winding apparatus includes a temporary suspending step of temporarily suspending operation of the winding device in the middle of winding the fed-out fiber portion around the workpiece. In the temporary suspending step, the length of the feeding path is increased by moving the pressing member while causing the pressing member to press against the fed-out fiber portion in a state of continuing to feed out the fed-out fiber portion from the fiber roll portion.

An apparatus, system and method for a new and improved coiling system that provides sensors to a computer control on the traverse while winding wherein the sensors mounted on the traversing mechanism to detect flanges of different width or reel and spools as the flanges are approached during winding that provides an automatically turnaround point without human intervention and is computer controlled with communication from the sensor.

Machine for controlling the shape of a reel of web product, comprising a pick-up zone for at least one reel to be evaluated, a moving apparatus of said at least one reel from said pick-up zone to an unloading zone, and an evaluation apparatus of at least the outer diameter of the reel, configured to act between said pick-up zone and said unloading zone.

The winding system has an electrode plate unwinding mechanism, a separator unwinding mechanism, a winding mandrel, a cutter, and an auxiliary wheel mechanism. The electrode plate unwinding mechanism is configured to unwind an electrode plate, the separator unwinding mechanism is configured to unwind a separator; the winding mandrel is configured to wind the electrode plate and the separator to form a winding core; the cutter is configured to cut the electrode plate and is arranged upstream of the winding mandrel; the auxiliary wheel mechanism is arranged downstream of the cutter, where the auxiliary wheel mechanism includes an auxiliary wheel, a first drive member, and a second drive member, the first drive member is configured to drive the auxiliary wheel to move closer to or away from the electrode plate. The second drive member is configured to drive the auxiliary wheel to rotate to adjust the tension of the electrode plate.
