Abstract:
1. An apparatus for separating plastic film material from waste, comprising: a supply track for supplying waste, the supply track extending in a supply direction to its downstream end; and a plurality of hooks mounted on a drum for circulating the hooks along a trajectory through an engagement area near the supply track and through a disengagement area downstream of the engagement area; wherein the engagement area is located higher than the supply track and/or in said supply direction beyond the downstream end of the supply track, such that, in operation, material that is to be engaged selectively reaches the trajectory of the hooks in the engagement area, and a remainder of the waste passes by the trajectory of the hooks without contacting the hooks; and wherein the hooks project from the drum via openings in the circumferential surface of the drum and are retractable into a circumferential surface of the drum, wherein the hooks are coupled to the drum so as to be extended while moving through the engagement area; and wherein the hooks are mounted to the drum via double lever members that are pivotable relative to the drum and carry cam followers positioned for engagement by cam profiles that are arranged axially outside of the drum.
