Abstract
A picking mechanism comprises a flexible picking belt for securing to a belt wheel and made of plastics reinforced by a number of stranded and/or bunched groups of fibers. The fiber groups are disposed in an insert extending over the entire length of the picking belt and surrounded by a layer of plastics constituting the picking belt and free from the fiber in the fiber groups. The picking belt has an end portion remaining outside the winding area of the belt wheel and formed with a web-like raised part. The easily-manufactured, low-weight picking belt prevents exposure of fiber in the fiber group during a long period of operation.
