Abstract (en)
[origin: ES266772U] An expandable feed roller has two separate side-by-side discs fitted on a rotatable drive shaft. Each disc has circumferentially spaced fins extending inward toward the other disc and inclined toward the shaft. The fins of the two discs are interdigitated to form a thread-receiving valley between them. One of the discs is fixed to the shaft but the other is slidable axially along the shaft toward and away from the other disc so as to change the effective circumference of the base of the thread-receiving valley between the discs. A spring urges the two discs apart against an adjustment mechanism operable to change the relative axial positions of the discs while the drive shaft is rotating.
