A sheet supplying apparatus, which is capable of winding a sheet tightly, includes a driving unit configured to cause a roll including a wound consecutive sheet to rotate in a first direction for feeding the sheet or a second direction opposite to the first direction, a sensor that detects a leading end portion of the sheet separated from an outer circumferential surface of the roll, and a contact body that presses the outer circumferential surface. Before the sheet is fed, in a state in which the contact body presses the outer circumferential surface, the driving unit causes the roll to continuously rotate in the second direction until a detection cycle of the leading end portion by the sensor is less than a predetermined value.

A system for decurling a web from a roll of material comprises rollers, a decurling station actuator, a sensor, and a controller. The rollers are configured to pull the web along a path with an angle. The decurling station actuator is configured to shift one of the rollers relative to the other rollers to adjust the angle of the path. The sensor is configured to sense a characteristic of the roll of material and generate sensor data. The controller is configured to receive a signal representative of the sensor data and direct the decurling station actuator to shift one of the rollers based at least in part on the sensor data.

An apparatus is provided for handling overlay sheet material on a cutting apparatus including a conveyor for moving work material in a longitudinal direction and a support for positioning a tensioner frame adjacent the conveyor. A tensioner frame, attached to the support, has a nip wheel and a drive for rotating the nip wheel with a tangential speed in excess of the longitudinal conveyor speed attached to the tensioner frame. The nip wheel engages the overlay sheet material applying a tension thereto in the same longitudinal direction as the conveyor.

A medium supplying device includes a housing part configured to house a rolled medium obtained by winding a sheet, a pair of rollers disposed at a predetermined interval in the housing part, and a supplying belt with an endless annular shape provided around the pair of rollers and configured to rotate along with rotation of the pair of rollers. An outer peripheral surface of the rolled medium is supported with the supplying belt, and the supplying belt is driven into rotation to rotate the rolled medium to supply the sheet.

An electrode sheet rewinding apparatus for rewinding an electrode sheet includes a bobbin having a PET film wound therearound, a bobbin holder configured to hold the bobbin, a base plate located under the bobbin holder and configured to support the bobbin holder, a roller type touch roll configured to press an electrode sheet rewound around the bobbin above the bobbin to prevent meandering of the electrode sheet, a vertical plate located at one side of the base plate, the touch roll attached to the vertical plate, and an idle roller unit configured to form a tangential line to the electrode sheet rewound around the bobbin together with the touch roll. The idle roller unit includes an idle roller configured to maintain tension of the electrode sheet and to form a tangential line to the electrode sheet and two driving mechanisms configured to change the position of the idle roller.

Apparatus for applying a strip P comprising at least one microcreped paper to a carrier material T, where the apparatus comprises the strip P, wound to a reel S, and rotatably mounted rollers R.sub.1, R.sub.2 and R.sub.3 for guiding the strip P at least partly unwound from the reel, where the at least one microcreped paper comprised in the strip P wound to the reel has a tensile strength of at least 8 kN/m, an extensibility of at least 4% and a tearing resistance of at least 1200 mN.

A device for introducing patterns by radiating a wound continuous substrate. The device provides patterning during continuous roll-to-roll movement without material slippage and with minimal distortion by providing a dancer roll between a processing drum and an unwinder roll on one side, and a winder roll on the other side, for tautly guiding the continuous substrate along a contact surface of at least half of the circumference of the processing drum in order to drive the continuous substrate without slippage. The dancer rolls are adapted to tautly guide the advancing substrate web and returning substrate web with a constant force, and an equilibrium is adjustable between a defined counterforce and the constant action of force on the dancer roll by a stabilization device, and is maintained constant by a controller based on measured deflections of the dancer roll by controlling the rotational speed of the unwinder and winder rolls.
