A display apparatus includes: a flexible first layer including a bending area; an adhesive layer on an upper surface of the flexible first layer; and a second layer attached to the flexible first layer by the adhesive layer. A direction of internal stress at a first portion of the flexible first layer is different from a direction of internal stress at a second portion of the flexible first layer, when the flexible first layer is in a flat state.

A biaxially stretchable laminated fabric composite material includes a four-way stretchable fabric and a barrier film. The barrier film and the fabric are selectively attached at a plurality of individual bond points. When the fabric is in an unstretched state, random folds are formed in the unbonded regions of the barrier film. When the fabric is in a stretched state, the random folds are partially or fully flattened to allow the biaxially stretchable laminated fabric composite material to biaxially stretch.

The plurality of driving rollers is configured to drive the overlapped foil and the composite current collector to downstream. The coiling roller is configured to wind up the composite current collector having the foil welded thereon.

Methods for manufacturing printed laminates or elastic printed laminates are disclosed. The printed laminates may have a first extensible material and a second extensible material. The first extensible material may have a plurality of repeating graphic sets each having a repeating graphic set length. The first extensible material may have a first strain and the second extensible material may have a second, different strain. The second strain may be constant. The first strain may be variable to correspond to the repeating graphic set lengths to a predetermined laminate pitch. The first and second extensible material may be joined together at a point of joinder. An elastic member, such as a plurality of elastic strands, for example, may be positioned intermediate the first and second extensible materials to form an elastic laminate.

A lamination machine has at least one material source which is in the form of a sheet feeder for material to be laminated. The lamination machine has at least one lamination unit that includes at least one first lamination source for laminating material, the at least one first lamination source being configured as a first roll changer and having at least two first roll holding devices.

A separation device is usable for separating portions of a material web. The separation device has at least one front clamping device, with at least one front clamping point, and at least one rear clamping device, with at least one rear clamping point, and at least one first stretching element. The separation device can be switched between at least one traversing mode and at least one separation mode by the movement of at least the at least one first stretching device between at least one first traversing position and at least one first separation position. A transport line is the shortest connection between the at least one front clamping point and the at least one rear clamping point, that connection line completely on a vertical reference plane and traversing or running at a tangent to any component of the separation device on the respective same side as one of a transport path provided for the material web and the portions to be separated. The transport line, in the at least one separation mode, is 2 mm longer than in the at least one traversing mode and has the smallest radius of curvature in the at least one separation mode of at least 0.05 mm. A first reference plane and a second reference plane are mutually spaced apart in an axial direction and a first transport line, lying on the first reference plane, and a second transport line, lying on the second reference plane, have different lengths when the first stretching element is located in the at least one first separation position.

Plastic flooring having registration system contains: an electronic control unit electrically connected with roller equipment and the registration system, the roller equipment is configured to deliver a substrate, a printing layer, and an abrasion resistance layer toward a rolling device. The rolling device includes a fourth roller set having pressing patterns identical to surface patterns of the printing layer, and the registration system has a first sensor, a tension regulator, and a second sensor. The first sensor is disposed on a delivery path of the printing layer which corresponds to the first sensor and has multiple positioning points.
