A transfer system for transferring a stack (101) of flat elements to a processing device includes a delivery ramp (103) with a receiving surface (104) for receiving the stack (101), a first comb structure (121) having at least one first supporting platform (123) on which at least an edge portion (115) of the stack (101) is supportable, wherein the first comb structure (121) is mounted to the delivery ramp (103), and a second comb structure (122) having at least two second supporting platforms (124) on which at least the edge portion (115) of the stack (101) is supportable, wherein the second comb structure (122) is configured for supplying the stack (101) to the processing device. The first supporting platform (123) and the second supporting platforms (124) are arranged along a first direction (109), one after another, in an interleaved manner such that the edge portion (115) is supportable on the first supporting platform (123) and the second supporting platforms (124). The first comb structure (121) and the second comb structure (122) are movable along a lifting direction (110) with respect to each other such that the edge portion (115) of the stack (101) is supportable selectively by the first supporting platform (123) or by the second supporting platforms (124), wherein the two second supporting platforms (124) are spaced along the first direction (109) such that the first supporting platform (123) is movable along the lifting direction (110) through a space between the two second supporting platforms (124).
