Discussed are a flexible display apparatus and a rollable display apparatus comprising the same, in which rigidity reliability is secured against a physical impact. The flexible display panel includes a display unit provided on a flexible substrate and a back cover disposed on a rear surface of the flexible display panel. The back cover includes a panel supporting part including a plurality of openings, having a size greater than a width of the flexible display panel, and supporting the flexible display panel, and a sidewall part protruding from each of one edge and another edge of the panel supporting part.

The present invention relates to a converting machine, i.e., a machine for winding or unwinding a strip of material on coils, particularly configured to process a delicate material.

In particular, the invention is directed to a machine (1) for converting coils of a material into smaller coils, comprising a loading unit (2) for automatically loading a strip (N) of material into the machine (1), an accumulation unit (3) of the strip (N) being processed, and a winding unit (4) of the strip (N) on a winding shaft (5, 5) to form respective coils (B), characterized in that the loading unit (2) comprises an accompanying system (6) for the strip (N) from the loading unit (2) to the winding unit (4), said accompanying system (6) consisting of a double chain (7), comprising a first chain (7a) and a second chain (7b) and an accompanying bar (9) driven by said first and second chains (7a, 7b), wherein the double chain (7) develops in a loop along a path (P) and wherein the accompanying bar (9) is movable along the loop-shaped path (P) and is configured to drive the strip (N) from the loading unit (2) to the winding unit (4) and then, after releasing the strip (N), to return to the starting point in the loading unit (2).

A transport control method for use in transporting a medium in a predetermined direction by an upstream drive roller and a downstream drive roller, to operate the downstream drive roller by using PID control based on a detection value of a tension sensor disposed downstream of the upstream drive roller and upstream of the downstream drive roller for detecting tension. The transport control method includes a stable state determining step for determining, at time of the operation, whether a difference between the detection value of the tension sensors and a target value is within a stable width to make a stable state which maintains a stability time; and a gain decreasing step for decreasing a gain of the PID control to be less than an initial value when the difference is determined to be in the stable state.
