The separator production method in accordance with an embodiment of the present invention includes a coated article winding off step of winding off, from a core, a separator original sheet which has been taken up in a coated article taking up step of winding the separator original sheet on an outer peripheral surface of the core while oscillating the core in a rotation axis direction, and the core is oscillated in the rotation axis direction in the coated article winding off step.

Maintaining a level of tension on material as it is processed in a manufacturing operation assists in the processing of the material. The tension of the material as it is fed through a process station is maintained by a material sag portion, such as an unsupported portion of the material extending between a roll of the material and the process station. The formation of the sag portion and the loading of the material forming the sag portion are automated and adjusted with a system having a material storage retrieval system, a shuttle, a tensioning device, and/or a processing station.

The medium feed device has a meandering detection sensor which detects position displacement of a recording medium in a width direction, and a control section which controls driving of a width movement unit based on detection results by the meandering detection sensor. The control section stops driving of the width movement unit when stopping feeding of the intermittent feeding.

The invention relates to an unwinding system, an assembly and a method for unwinding a tire component from a stock reel and for outputting said tire component in a transport direction, wherein the unwinding system comprises a reel station, an output conveyor and a transfer device for transferring a leading end of the tire component from the reel station to said output conveyor, wherein the transfer device comprises a retaining member which is movable along a guide path between a pick-up position and a release position, wherein the retaining member comprises a retaining surface for releasably retaining the leading end of the tire component, wherein the transfer device further comprises an arm that is rotatable around the inverting axis for moving the retaining member along the guide path, wherein the retaining member is movable with respect to the arm in an extension direction perpendicular to the inverting axis.

Unwinder of a thin ply product wound on a roll, comprising a first roll-holder assembly equipped with a first unwinding rod for a respective roll, on which the roll is adapted to be supported, and which has an axis of rotation transversal to the direction of movement of the ply unwound from the roll, a second roll-holder assembly equipped with a second unwinding rod of a respective roll, on which the roll is adapted to be supported, said second rod being parallel to said first unwinding rod of the first roll-holder assembly, said second roll-holder assembly facing said first roll-holder assembly in an unwinding zone, a ply splicing assembly placed above said first and second facing roll-holder assemblies, a ply accumulation unit to allow automatic switching between a roll being unwound in one said roll-holder assembly and a spare roll provided in the other roll-holder assembly, a system for the lateral movement of each of said unwinding rods with respect to said unwinding zone, from said unwinding zone to a loading zone wherein said rolls are outside said winding zone to facilitate loading the rolls into the respective roll-holder assemblies, wherein said splicing assembly can be moved from a working position above the two said roll-holder assemblies in said unwinding zone, to a working position above an extracted roll assembly in the loading zone, to allow preparation for splicing of the leading edge of the ply wound on the spare roll.

Unwinder of a thin ply product wound on a roll, of the type with automatic switching of the unwinding roll with a spare roll, said unwinder comprisinga first roll-holder assembly equipped with a first unwinding rod for a respective roll, on which the roll is adapted to be supported, and which has an axis of rotation transversal to the direction of movement of the ply unwound from the roll,a second roll-holder assembly equipped with a second unwinding rod for a respective roll, on which the roll is adapted to be supported, said second rod being parallel to said first unwinding rod of the first roll-holder assembly, said second roll-holder assembly facing said first roll-holder assembly in an unwinding zone, wherein of said two roll-holder assemblies, one assembly holds the unwinding roll and the other assembly holds the spare roll to be switched,a ply splicing assembly placed above said first and second facing roll-holder assemblies,a ply accumulation unit to allow automatic switching between a roll being unwound in one said roll-holder assembly and a spare roll provided in the other roll-holder assembly,a transversal position correction system for the side edges of the plies on the rolls present in said roll-holder assemblies.

A regulation device regulates movement in a width direction of a rolled sheet which is a recording medium of a printer. The regulation device includes: a first rack gear connected to one guide support unit supporting the rolled sheet so that movement to one side of the width direction is regulated, and provided to be movable in the width direction; a second rack gear connected to the other guide support unit supporting the rolled sheet so that movement to the other side of the width direction is regulated, and provided to be movable in the width direction; a pinion gear engaging with the first and second rack gears; and a regulation gear that engages with the first rack gear to rotate and regulates the movement of the first and second rack gears by regulating the rotation.

The invention relates to an unwinding system for unwinding a tire component from a stock reel and outputting said tire component in a transport direction, wherein the unwinding system comprises a reel station, a conveyor and a transfer device, wherein the conveyor extends at least partially above the reel station, wherein the transfer device comprises a retaining surface for releasably retaining the tire component along a guide path between a pick-up position for picking up the tire component from the reel station and a release position for disposing the tire component on the conveyor, wherein, in the release position, the retaining surface is facing towards the conveyor, and wherein the retaining surface is offset between the release position and the pick-up position over an offset angle of at least ninety degrees around an inverting axis that is parallel to the conveyor and perpendicular to the transport direction.
