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 winding head includes a first supply spool for receiving a first fiber strand and a second supply spool for receiving a second fiber strand, an impregnation unit through which the first fiber strand and the second fiber strand can be guided for impregnation with liquid resin, a first deflection roller assigned to the first supply spool, and a second deflection roller assigned to the second supply spool. The winding head further includes a bundling roller, at which the first fiber strand and the second fiber strand can be combined to form a complete fiber strand upstream of the impregnation unit, and which is arranged downstream of and spaced apart from the first deflection roller and the second deflection roller. A spreading roller is arranged downstream of and spaced apart from the bundling roller to form two fiber spreading sections.

A paint roller manufacturing system includes a cover dispenser for continuously dispensing a windable width of paint roller cover fabric, a fabric supporting and advancing device for supporting the fabric and maintaining a width-wise dimension of the paint roller cover fabric as the fabric advances, a fabric coating applicator for applying a coating to the back side of the paint roller cover fabric while the fabric supporting and advancing device maintains the fabric in a width-wise dimension, and a compressing roller positioned downstream of the fabric coating applicator and configured to apply a compressive force on the coating after it has been applied to the back side of the paint roller cover fabric and while the fabric is supported by the fabric supporting and advancing device. In two-strip embodiments, first and second strip dispensers continuously dispense a first and second windable width of strip material. A guide system guides the first and second strip coming from the first and second strip dispensers to be wound about a mandrel and guides the coated paint roller cover fabric from the fabric supporting device to be wound about the first and second strips. An adhesive applicator is configured to apply adhesive on substantially all of the outer side of the first and second windable strips and positioned to apply adhesive to the outer side of the first and second windable strips upstream of a location where the coated paint roller cover fabric is wound about the first and second strips.

A helical winding unit includes a plurality of guides arrayed in a peripheral direction of a liner, and adapted to guide each of a plurality of fiber bundles supplied to the helical winding unit to the liner, and an opening member arranged downstream of the plurality of guides in a travelling direction of the fiber bundle, and including an inner peripheral surface for forming a hole, through which the plurality of fiber bundles are inserted from one side to the other side in the axial direction. A plurality of opening surfaces on which the plurality of fiber bundles travel while making contact are formed on the inner peripheral surface of the opening member, and a cross-sectional shape orthogonal to the axial direction of each opening surface is linear.

A fibrous preform for manufacturing an annular housing made of composite material for a turbine engine includes at least one layer that has a fibrous texture, has a three-dimensional or multilayer weave, and extends about a longitudinal axis. At least one mat includes a thermoplastic material filled with carbon nanotubes and extending about the axis. At least one multiaxial fibrous sheet extends about the axis. The at least one mat is inserted between the fibrous sheet and the at least one layer having a fibrous texture.

The invention relates to a curved product, and in particular an armor product. The armor product is produced by a filament winding process in which a plurality of reinforcing elements in the form of fibers and/or tapes are impregnated with a polymer matrix and wound onto a mandrel. The polymer matrix comprises a solution and/or dispersion of a polymer in a carrier fluid, which carrier fluid is at least partly evaporated during and/or after winding. The armor product comprises a high amount of reinforcing elements with respect to the total mass of the product.

Fiber composite components can be formed by winding fibers along tracks of a winding spool of a winding core. The fibers may either be pre-coated with a curable resin, or the curable resin may be applied to the fibers after the fibers are wound along the tracks of the winding spool of the winding core. The curable resin may also and/or alternatively be applied to a mold that receives the fibers wound about the winding spool. The curable resin may then be cured, after which the winding spool and the winding core may be removed in order to release the fiber composite component. In some cases, the winding spool may be removed from the fiber composite component by moving the winding spool inwardly towards an inside of the winding core.

A steering-column assembly for a motor vehicle may include a steering spindle rotatably mounted in a steering-column tube, which steering-column tube is mounted in a console that connects the steering-column directly or indirectly to a body of the motor vehicle. At least one of the components of the steering-column, such as the console, for example, may include a fiber composite component that can be formed by winding fibers along tracks of a winding spool of a winding core, introducing a curable resin into the fibers or a mold to be used with the wound fibers, curing the wound fibers, and removing the winding spool and the winding core so as to release the fiber composite component. The fiber composite component may then be fitted into the steering column assembly.
