APPARATUS AND METHOD FOR FABRICATING FLEXIBLE DISPLAY SCREEN

A fabricating apparatus and method for a flexible display screen. The fabricating apparatus for the flexible display screen comprises a roller mechanism and a jig (21); the jig (21) has a bearing surface (211) for bearing a flexible display panel (1); the bearing surface (211) is a curved surface; the roller mechanism comprises a roller (31); and the axis (x) of the roller (31) is parallel to the plain line (y) of the bearing surface. The fabricating apparatus for the flexible display screen is used for attaching a support layer (2) to the flexible display panel (1), so that the flexible display panel (1) is better bonded to the support layer (2), thereby reducing the probability that the flexible display panel (1) is separated from the support layer (2) during normal use.

Method of aligning a flat or profiled metal sheet
11504756 · 2022-11-22 · ·

A method of aligning a flat or profiled metal sheet with preformed notches on the two sides of the metal sheet when the sheet enters into a bender or folding machine directly from a roll forming machine linked or joined to the folder. The metal sheet has to be effectively aligned on the folder before folding to avoid potential damages to the metal sheet of not being properly squared or angled on bending while reducing the times to produce the folded products. Moreover, this method according to the invention allows the metal sheet to feed directly into the folder from the rollformer without having to pass through an intermediary transfer table or aligning device/machine before entering the folder for folding or manual alignment in the folder.

Bending beam for a swivel bending machine

An elongated bending beam for a swivel bending machine has an approximately C-shaped beam cross section and two bending tools, which are opposite one another relative to a preferably horizontal central plane, and which run facing one another in the longitudinal direction of the bending beam, between which a workpiece portion of a workpiece to be bent can be introduced. An angle-measuring system for contactlessly measuring a bending angle is arranged inside the C-shape beam cross section, with which a bending angle can be measured relative to a reference plane at a workpiece section bent by one of the bending tools. The angle-measuring system also includes a first angle-measuring unit arranged below the central plane and having a first measuring region positioned substantially above the central plane, and a second angle-measuring unit arranged above the central plane and having a second measuring region positioned substantially below the central plane.
