An apparatus for manufacturing a bending panel of a display includes a lower mold having a first member on which a target panel is placed, an upper mold disposed adjacent the lower mold and including a second member including a first surface to press a portion of the target panel and a second surface having a first slope with respect to the first surface, and side molds disposed at opposite sides of the lower mold and each having a third member with a third surface complementary to the second surface of the second member. The first slope is smaller than about 90 degrees.

A process for winding a filament around a winding support. The winding support has a cylindrical shape with dome-shaped longitudinal ends and a roll axis, and is held by a holding device fixed to a base. The process includes the following, occurring in synchronization, feeding a filament, by means of at least one feeding device, towards the winding support, rotating the winding support with respect to the base around a pitch axis of the winding support, rotating unlimitedly the at least one feeding device around a yaw axis of the winding support with respect to the base, and/or rotating unlimitedly the winding support around the yaw axis of the winding support with respect to the base, and rotating unlimitedly the winding support with respect to the base around the roll axis of the winding support.

A laying unit for producing a fiber composite component includes a drive device which is formed for magnetic cooperation with a running face, which provides a magnetic field and/or is ferromagnetic, to advance the laying unit on the running face. A device for producing a fiber composite component comprising a laying unit of this type and a method for producing a fiber composite component comprising a device of this type are disclosed.

A pulsating corrugator is provided with at least one secondary mold block that is selectively used for forming a spigot connection as the corrugated or ribbed pipe is formed. Preferably, the primary mold blocks used to form the corrugated pipe are also used to assist in further cooling of the formed spigot connection once released from the secondary mold block. The corrugator also includes a controller used to provide different air pressure as the mold blocks move past extrusion outlets of an associate extruder.

A paint roller manufacturing system and method are described. In an embodiment, an inner strip of material and an outer strip of material are wound about a mandrel in offset relation. The inner strip of material and the outer strip of material each comprise material that results in a final paint roller which shrinks by less than 2.5 percent of the final paint roller axial length, or which has shrinkage that varies by less +/0.1%, upon hardening and setting. An adhesive is applied to at least a portion of the outer strip as it is wound about the mandrel. A length of fabric is wound about at least the outer strip to form a paint roller tube, and compression is applied to the paint roller tube while advancing the paint roller tube in a direction parallel to the mandrel. A precision measuring or sensing device is used to control a cutting device causing the cutting device to cut the advancing paint roller tube into pre-selected lengths prior to the paint roller tube hardening and setting.

A contoured composite laminate stiffener is fabricated by assembling a substantially flat composite laminate charge and forming the charge into a substantially straight stiffener having a desired cross sectional shape. A contour is formed in the stiffener which has an inside radius and an outside radius. Ply wrinkling is substantially eliminated by reducing compression strain on the inside radius as the stiffener as being contoured.

Disclosed are a composite layer, a composite layer lamination and a method of manufacturing a composite layer. The composite layer includes: a resin core formed in a plate-shape and comprising with a plurality of guide protrusions protruding along an edge of the resin core as being spaced apart at a predetermined distance from each other and a plurality of guide notches between the plurality of guide protrusions; and a reinforcing fiber wound around the resin core via the plurality of guide notches functioning as a guide for the reinforcing fiber.
