The deformation portion (10) comprises at least one cut (12) extending from the contact surface (2) to the central portion (6), the cut (12) being arranged such that the deformation portion (10) comprises at least one elastically deformable segment (16).

An apparatus includes a bi-modal roller configured to rotate about a longitudinal axis of the bi-modal roller. The bi-modal roller includes two ends and a rolling outer surface. The rolling outer surface is divided into a convex portion and concave portion. The concave portion includes at least one concave curve extending longitudinally between the two ends. The concave portion is configured to, when a film physically contacts the concave portion, affect translation of the film in response to a stick condition or a slip condition. The convex portion includes at least one convex curve extending longitudinally between the two ends. The convex portion is configured to, when the film physically contacts the convex portion, affect translation of the film in response to a stick condition or a slip condition.

An items processing apparatus for placement and singulation of flat items has a placement device and a feed deck and a separation device. A portion of the placement device is arranged below the placement deck of the apparatus. The feed deck has an opening for an separation roller, and a portion of the separation device arranged above the feed deck. This portion and the separation roller form a gate of the separation device for the singulation of a stack of flat items. A control computer controls the placement device and separation device. The placement device is equipped for edge alignment of a stack of flat items with different formats and has at least two transport elements, which enable an automatic displacement of the stack transverse to the transport direction and placement of the stack at an alignment wall, as well as a transport of the stack in the transport direction toward the feed deck of the separation device, as well as a displacement of the stack counter to the transport direction. A movement assembly is provided to move the portion of the separation device in a direction counter to the transport direction. The control computer controls the alignment state of the transport elements of the placement device of the items processing apparatus, and controls the movement of the portion of the separation device. The aforementioned portion enables a displacement of the stack counter to the transport direction.

Disclosed herein is a drum for roll-to-roll deposition to rotate about a longitudinal axis. The drum is circular in a widthwise cross-section and has a shape in which opposite longitudinal edge portions each have a narrower width than a longitudinal central portion. By using the drum for roll-to-roll deposition according to embodiments of the present disclosure, it is possible to remove wrinkles occurring on a flexible substrate when a roll-to-roll deposition process is performed. As a result, it is possible to manufacture a film roll having a deposition layer with excellent widthwise thickness uniformity.
