A sheet can be securely drawn out of a sheet roll irrespective of an outer diameter of the sheet roll, and then, can be conveyed. A driven roller moves according to the outer diameter of the sheet roll, so as to be brought into press-contact with an outer periphery of the sheet roll from below, with respect to the direction of gravity, irrespective of the outer diameter of the sheet roll. An arm member moves according to the outer diameter of the sheet roll, so as to guide a lower side of the sheet drawn through above the driven roller irrespective of the outer diameter of the sheet roll.

An expansible chuck for holding hollow cylindrical cores used for winding and unwinding sheet material. A portion of the chuck body nearest the flange is stepped up so that the diameter of the chuck near the flange is slightly larger than the diameter of the rest of the chuck. The stepped up portion centers the chuck within the core which helps the expanding elements to uniformly grip the core.

A printing apparatus prints an image on a recording medium unwound by an unwinder. The recording medium is wound around a first winding shaft in order from a beginning edge to an ending edge of the recording medium. The wound recording medium is rewound, and the rewound recording medium is wound around a second winding shaft in order from the ending edge to the beginning edge of the recording medium.

A fastening strap unit includes a frame with a mandrel and a strap connected thereto. The strap is wrapped to the mandrel, and the first end of the strap is fixed to the mandrel and a hook is connected to the second end of the strap. A shaft extends from the frame and a motor drives the shaft which drives the mandrel. A first sensing chip is connected to the second end of the strap and a second sensing chip is connected to the first end of the strap. A sensor is connected to the frame so as to detect the first sensing chip or the second sensing chip when the strap is retracted or released to its final position, and the motor is stopped.

In one example, a device for unwinding or winding multiple rolls of print substrate includes multiple spindles each to hold a roll of print substrate and a differential operatively connected to one end of each spindle. The spindles are aligned with one another lengthwise along a spindle axis and the differential is to output torque along a differential axis offset from the spindle axis to turn the spindles on the first axis.

A continuous winding method produces a continuously wound electrical device, such an undulator. A continuous tape is wound about a series of turn around pins and in grooves in a magnetic core. A plurality of winding stacks are created, each transitioning to the next sequential stack by a transition tape portion extending from one turn around pin to the next turn around pin, which is position opposite with regard to the location of the pin on the magnetic core.
