Abstract
A method of and device for feeding into the charging funnel of a worm machine strip-shaped or irregularly formed partial pieces of material, especially rubber, dosed by weight as components of a mixture, according to which the pieces are weighed individually and are conveyed to the worm machine in a cycle sequence time compensating for the difference of the rated value or preselected weight and the actual value of the weight of the individual piece. The device for practicing the method according to the invention has an electric scale preferably connected to an analog converter, which scale feeds a starting voltage proportional to the actual weight of the partial pieces to a rated value -- actual value comparator and to an electric calculator which latter determines the change in the cycle sequence time in conformity with the deviation from the preselected weight of the respective partial piece.
