Abstract
A sliver delivery and opening device having a pivotably seated sliver intake cylinder driven by a worm gear arrangement comprising a worm wheel connected to the sliver intake cylinder that meshes with a worm affixed to a drive shaft. The worm includes thread windings conforming to a superimposed profile that axially offsets the worm relative to the worm wheel, thus preventing placement of a tooth of the worm wheel on a thread head of the worm when the worm wheel pivotally engages the worm. The amount of offset is measured between a plane of symmetry intersecting the superimposed profile of the worm thread windings and a pivot plane intersecting a center axis of the worm wheel. A positioning device, comprising at least one magnet and a ferromagnetic positioning element, prepositions the worm wheel relative to the pivot plane for pivotal engagement of the worm wheel and the worm.
