Abstract
The guide for a picking element is provided with five plane guide surfaces which are peripherally disposed about the picking tunnel. These five guide surfaces are disposed on each of the single guide tooth or are distributed between a separately constructed guide hook and an adjacent separately constructed guide support. Any two adjacent guide surfaces are disposed to define an angle of at least 90 degrees in order to reduce the friction forces operating between the guide surfaces and the picking element.
