The horngears can be arranged for forming at least two closed paths for braiding. Each horngear has a driving gear and a hornplate. Each horngear can be selectably operated in a first mode, to rotate with the driving gear, and in a second mode, in which the driving gear rotates, but the hornplate does not. Bobbin carriers are positioned on some of the horngears. A track is configurable in: a first flat braiding mode with the carriers arranged on the horngears, so that there is one or more separate closed path for forming a first flat braid configuration; and a second flat braiding mode for forming a second flat braid configuration different from the first flat braid configuration. A switch is provided for changing a configuration of the track between the first and second flat braiding modes. Full Article
nat Method for braiding reinforcing fibers with variation in the inclination of the braided fibers By www.freepatentsonline.com Published On :: Tue, 24 Feb 2015 08:00:00 EST A method of braiding reinforcing fibers on a mandrel (8) with a machine having a ring (9) carrying at least two series of reels of fibers, by moving the mandrel at a predetermined forward speed while moving the two series of reels along the ring (9) so that they cross while rotating in opposite directions and at a predetermined speed of rotation about an axis (AX) of the ring. The braid is formed on the mandrel (8) in the vicinity of a region of convergence (R) of the fibers that together define a conical shape (C). The method comprises: a step of reconfiguring the machine in which the angle (a2) at the apex of the cone (C) defined by the fibers takes on a new value (a2); and a step of restarting braiding in which the movement of the reels along the ring (9) and the forward movement of the mandrel (8) are re-established with a new speed of rotation and a new speed of advance.

nat Combination scoop and funnel By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT A combination scoop and funnel apparatus provides a scoop portion defining a dry material reservoir having an open top and a downwardly tapered conical bottom portion which terminates in a discharge aperture. A handle is joined to the scoop reservoir. A movable frusto-conical funnel member defines a funnel aperture at its lower end and an open top at its upper end. The funnel member supports a valve slide which extends upwardly through the discharge aperture and further supports a valve cap on the upper end thereof. The valve member is movable between a downwardly extending valve closed configuration and an upwardly positioned valve open configuration. Full Article
