An apparatus and method for crimping an implant (30), in particular an intraluminal endoprosthesis, which can adopt either a compressed state or an expanded state, at least over part of its length including a roll arrangement comprising at least three rolls (1, 2, 3) for clamping the implant (30) therebetween, wherein the spacing of at least one roll (1) of the roll arrangement relative to each of the other at least two rolls (2, 3) can be reduced in such a way that an implant (30) clamped between the rolls (1, 2, 3) can be transferred from the expanded state into the compressed state, at least over part of its length.
