The invention relates to an apparatus for providing web-like interleaving sheet material on one track or on multiple tracks at a cutting zone in which products supplied on one track or multiple tracks are cut into slices and interleaving sheets are introduced that are cut off from the provided interleaving sheet material in the cutting zone, having a removal device that is configured to remove the material web from a material store, and having a loop store in which the material web forms a loop having a loop portion at the incoming side and a loop portion at the outgoing side, wherein the loop store provides a reception space for the loop whose one side forms a support for the one loop portion and whose side opposite the support forms a boundary for the other loop portion.

A transport device includes a first driving roller configured to contact an outer circumferential surface of a roll body on which a medium is wound, and apply rotational torque to the roll body, a second driving roller configured to unwind the medium from the roll body, a first drive unit configured to drive the first driving roller, a second drive unit configured to drive the second driving roller, and a control unit configured to control the first drive unit and the second drive unit. The control unit controls the first drive unit, based on a magnitude of a load current flowing in the second drive unit.

An inkjet recording apparatus includes a feeding-side motor, an inkjet recording unit, a winding-side motor, a feeding-side roll-diameter measuring unit, a winding-side roll-diameter measuring unit, and a motor drive controller. Based on a relationship between motor rotating speeds and roll diameters under conveyance of the recording medium at a specified conveyance speed, the motor drive controller determines a first rotating speed corresponding to a feeding-side roll diameter measured by the feeding-side roll-diameter measuring unit and moreover determines a second rotating speed corresponding to a winding-side roll diameter measured by the winding-side roll-diameter measuring unit to drive the feeding-side motor at the first rotating speed and moreover drive the winding-side motor at the second rotating speed.

A printing apparatus includes first and second supplying portions, a printer, and a winding unit. The first supplying portion can supply a recording medium on a conveyance route to the printer for first surface printing. The winding unit then rotates in a first direction to wind the printed recording medium. A wound recording medium edge is located at a specific location and then guided to a conveyance route opening portion if the wind direction is a second direction. After the edge is at the specific location, the recording medium is supplied through the opening portion to the printer for second surface printing. If the second supplying portion supplies the recording medium for first surface printing, then it supplies the medium for second surface printing. If a user sets a wound-in-advance recording medium to the second supplying portion, the second supplying portion supplies the set recording medium to the printer.

There is provided a printing apparatus that is capable of reducing an occurrence of transport disorder of a medium when transporting the medium unwound from an unwinding unit that holds a roll body.

The printing apparatus performs printing on the medium unwound from the roll body having the medium wound into a cylindrical shape, the printing apparatus including: an unwinding unit 40 that rotatably holds the roll body and unwinds the medium by rotating the roll body; a transport unit that transports the medium unwound from the unwinding unit 40; and a printing unit that performs printing on the medium transported by the transport unit. The unwinding unit 40 includes a first rotary body 441 that is integrally rotatable with the roll body by engaging with a first end of the roll body, a second rotary body 451 that is integrally rotatable with the roll body by engaging with a second end of the roll body, a first motor 442 that rotatably drives the first rotary body 441, and a second motor 452 that rotatably drives the second rotary body 451.
