Abstract: Method for warping with a cone sectional warping machine, which winds threads in bands on a warping drum, wherein a support for a thread guide comb and the warping drum are displaced in relation to each other in correspondence with the increasing thickness of winding and predetermined warping data. The first band is monitored during a first measuring phase by a roll exerting contact pressure and the monitored displacement path is recorded as a function of the number of rotations of the warping drum. Roll pressure on the winding during the measuring phase is continuously monitored using measuring techniques. Displacement of the support is corrected if monitoring results differ from a predetermined setpoint. In order to even out the formation of the wind, the roll is arranged at a given distance from the warping drum when warping of the first band is started. The monitoring of the roll is automatically started with increasing thickness of the winding as soon as the winding causes the roll to rotate.

Abstract: A method of making a balloon expandable braided stent with a restraint to initially prevent self-expansion and the resulting product. Multiple strands of a resilient metal or plastic are braided to form a tubular configuration of a predetermined outside diameter which assumes a lesser diameter when the tubular stent is longitudinally stretched. When in its stretched condition, it is coated with a polymeric material which is then cross-linked to effectively “freeze” the intersections of the braided structure holding it in its reduced diameter configuration. The tubular stent is designed to be placed within a body vessel using a balloon stent delivery catheter. When the balloon surrounded by the braided wire stent is inflated, the stent expands initially to an extent to break the bonds of plastic material between the intersections of the strands, thereby permitting self-expansion to take place.
