In one aspect of the present subject matter, a method of forming a linear panel includes drawing a multi-layer panel material assembly having differing inner and outer material layers along a processing path. The method also includes heating the panel material assembly. In addition, the method includes forming the heated panel material assembly into a desired shape as the assembly is drawn along the processing path. Additionally, in another aspect of the present subject matter, a linear panel includes a body formed from a multi-layer panel material assembly having differing inner and outer material layers.

A sheet processing apparatus includes a rotating member, a switching unit, and a pressing unit. The rotating member is rotatable and has a facing portion that faces a fold section of a sheet. The rotating member rotates so as to switch the facing portion to another facing portion. Each facing portion is provided with a protrusion. A set position of the protrusion in an axial direction varies from facing portion to facing portion. The switching unit rotates the rotating member so as to switch the facing portion that faces the fold section. The pressing unit presses the protrusion of the facing portion against the fold section.

A method of roll forming a plurality of composite components. The method includes the steps: (a) laying a plurality of blanks onto a carrier strip, each blank including a stack of sheets of uncured composite material contacting a respective contact part of the carrier strip; (b) after step (a), forming the blanks and their respective contact parts of the carrier strip with a desired cross-sectional profile by passing the carrier strip carrying the blanks through a series of sets of rollers, each set of rollers performing an incremental part of a bending operation until the desired cross-sectional profile is obtained; (c) after step (b), separating the blanks along with their respective carrier strips from the rest of the carrier strip; and (d) before or after step (c), curing the blanks.

A forming device, system, and method for continuous forming of a semi-finished fiber product. The semi-finished fiber product is supported flatly from a first side and is at least locally restricted in its freedom of movement, for example pressed on and/or guided, on another side opposite the first side. The further restriction occurs in relation to a guiding area at at least one constant location or region past which the semi-finished fiber product is guided. Shaping tools and guiding areas defined thereby are used for support, and hold-down devices and their contact surfaces are used for further restriction. The further restriction is carried out transversely to a feed motion direction of the semi-finished fiber product through the forming device. The further restriction and the flat guidance serve to reduce formation of undulations and folds.

Disclosed is a terrace folding system of a secondary battery cell, including a transfer unit which transports a secondary battery cell; and a folding unit which is disposed along the transfer unit and is temporally separated from the transfer unit to fold a terrace of the secondary battery cell.

A duct that, in cross section, has one or more rounded portions is disclosed together with a method and a machine for producing it. The duct can be made from rigid foam panels with a facing on at east one side of the panels. A crimping element is used to form several substantially parallel indentations or crimps on a faced side of a panel, without breaching the facing, so that the crimped panel can be manipulated to form a section of duct with the crimps extending longitudinally. Depending on the number of crimps, the duct will appear more or less round in cross section although the crimped foam panels can be manipulated to have cross sections of different shapes such as oval. Adjacent duct sections may be joined, for example, with tape or bands, several of which are described.

An installation for forming a fiber preform, includes a follower roller. The follower roller presents a profile in section that has at least a first slope forming an angle with the axis of the follower roller and a second slope forming a second angle with the axis of the follower roller that is different from the first angle. The installation also has at least one backing roller presenting a shape complementary to the first and second slopes, the installation including a holder for holding each backing roller and configured to hold the backing roller at a predetermined distance from the first and second slopes or configured to apply contact pressure from the backing roller against the first and second slopes.

A composite forming station for forming a T-profile composite part from a planar laminate. The composite forming station includes in-line rollers arranged along a forming direction, wherein a thickness and/or edge angle each roller is greater than the preceding roller, wherein the rollers gradually splay apart feet sections of the planar laminate to convert the laminate to the T-profile composite part.

Disclosed herein are internally fluted shafts for sporting goods such as archery arrows, crossbow bolts, and golf clubs, as well as methods of manufacturing shafts with fluted internal diameters or bracing.

A method and a device for producing a reinforcing profile from at least one layer (1, 2, 3) cut out of a preimpregnated fibrous web are described, said layer (1, 2, 3) being applied to a mould core (4) determining the profile shape, being retained on the mould core (4) in the application region (6), and being pressed progressively onto the mould core, starting from this application region (6), transversely to the profile longitudinal direction, as far as the profile longitudinal edges. In order to create advantageous production conditions, it is proposed that the layer (1, 2, 3) be pressed incrementally progressively so as to be shaped onto the mould core (4), in the longitudinal direction thereof, with the aid of moulding punches (8) that are arranged offset with respect to one another both in the circumferential direction and in the longitudinal direction of the mould core (4) and are able to be forced in the direction of the moulding faces of the mould core (4).
