Function
The spreading system half-width X-Pander consists of two roller units each with three rollers that meet in the middle. Each unit has two fixed rollers and one moving roller. The width of the cord can be controlled by varying the bite angle of the moving center rollers. Spreading can be optimized by manually adjusting the correction angle.
Area of use
X-Pander spreading systems are used exclusively in hot-stretching plants before the traction station to achieve constant web width and uniform thread distribution.
Application
The X-Pander spreading system can be mounted in all positions. The infeed path should be the equivalent of at least half a web width, while the exit path should be kept as short as possible.
