An upper for an article of footwear is provided, having a braided structure comprising a first yarn having a first cross-sectional shape and a second yarn having a second cross-sectional shape different than the first cross-sectional shape. The first cross-sectional shape comprises an outer surface parallel to an inner surface in a rectangular orientation. Additionally, the first yarn is oriented such that at least a portion of the outer surface comprises the first side of the first yarn and at least a portion of the inner surface comprises the second side of the first yarn.

An apparatus for manipulating a material is provided. The apparatus may comprise a magnetic device arranged in a three-dimensional configuration. The apparatus may comprise a surface on which at least one carrier is configured to move. The magnetic device may be configured to provide a magnetic field for driving the carrier on the surface to manipulate a material. The apparatus may comprise a controller configured to control the magnetic device to modulate the magnetic field. The controller may be further configured to detect a position and/or motion of the carrier.

A bobbin head assembly for a maypole type circular braiding machine contains a spindle unit, a braiding material spool with braiding material and a bobbin head. The bobbin head contains a compensation plate and a torsion spring extending helically around the extended axis of the spindle unit. The torsion spring has a nose bent radially inwards towards the center at each of the two ends of the torsion spring coils. A spring seat is attached on the compensation plate, for receiving the torsion spring with a spring abutment element for fixing the nose of one spring end in a circumferential direction of the torsion spring. A fixing collar adjustably fixes the nose of the other spring end in the opposite circumferential direction at different positions along the circumferential direction. The position of the fixing collar can be secured in the circumferential direction with respect to the bobbin head.

Methods and systems for braiding sutures and the resulting constructs are disclosed. The sutures can have alternating bifurcated and non-bifurcated lengths. The sutures can have looped-ends, with both ends of the loop having contiguous braiding with the adjacent body or remainder of the suture. Braiding machines can have one or more bifurcating bars that can controllably obstruct or allow passage of the shuttle and carriers of the braiding machine. The controllable bifurcating bars can result in u-turns in the shuttle and carrier paths, such as a path encircling a horngear adjacent to the bifurcating bar, or passage of the shuttle and carrier across the bifurcating bar.

The invention relates to a braiding bobbin for a braiding device. The braiding bobbin includes a cylindrical braiding spool, from which a previously wound, multilayer ribbon can be unwound, wherein a first layer of the ribbon consists of a pre-impregnated fiber film, and a second layer of the ribbon consists of a protective film. In addition, the braiding bobbin includes a bracket to which the braiding spool is frontally and rotatably fastened. Additionally provided for the braiding bobbin is a cylindrical additional spool for winding the protective film of the unwound ribbon and a deflection element. The deflection element is fastened to the bracket, wherein the deflection element is secured spaced apart in the radial direction R to the braiding spool and designed for deflecting the protective film from the braiding spool to the additional spool.
