Process for handling, installing, compacting, splicing, and/or assembling composite stringers

Methods of assembling stiffened composite structures are disclosed. Some methods include forming a stiffener assembly by compacting it within a trough formed in a trunnion. A single trunnion may accommodate two or more different types of stiffeners, thereby avoiding the need for multiple sets of tooling. In some methods, a plurality of stiffener segments may be spliced together, thereby avoiding the need to transport and handle an entire stiffener. A vacuum chuck may be utilized in some examples to transfer the stiffener assembly from the trunnion to a transfer tool. The same vacuum chuck may be transferred along with the stiffener assembly on the transfer tool and loaded onto an inner mold line layup mandrel, where the vacuum chuck may be used to compact the stiffener assembly to the inner mold line layup mandrel.

20200290408 · 2020-09-17 · ·

The present invention relates to a method and an apparatus for applying noise reducing elements to tyres for vehicle wheels. Noise reducing elements (12), all equal to each other, are fed in succession on a conveyor (20) according to a predetermined path and are oriented on the predetermined path all in the same way. Tyres (2) of different sizes (C, P) are fed in succession on a conveyor (20) up to an application station (34). In the application station (34), the noise reducing elements (12) are picked up from the conveyor (20) and applied to radially inner surfaces of the tyres (2). The application comprises: arranging the noise reducing elements (12) with the larger dimension (L) directed in a circumferential direction or arranging the noise reducing elements (12) with the larger dimension (L) directed in an axial direction as a function of the sizes (C, P) of the tyre (2) in which they are applied.
