The stamping device is combined with a stop, against which blisters of the packing strip to be stamped out run. By use of the stop, an always similar position of the blisters within the packing strip is achieved in the case of different expansion behaviors of the continuous film. By use of a buffer zone for a part of the continuous film, matching to different continuous films is achieved. ## Claims ### Claim 1 A device for severing packing strips (11) having blisters (10) from a continuous film (12), having an advance device (15) that conveys the continuous film (12) step by step by at least a width of a packing strip (11), and having a severing tool (20) having a continuous outer cutting edge that determines an outer contour of the packaging strip (22) and adjoining at a specific distance in a conveying direction, a stop (30) is arranged in a covering region of the severing tool (20) and positioned to abut at least one blister (10) of the packing strip (11) to be severed, and wherein the stop (30) penetrates a cutout (29) in the severing tool (20), said cutout being within the bounds of said continuous outer cutting edge, said stop being parallel to a direction of motion of the severing tool. ### Claim 2 (depends on 1) The device as claimed in claim 1, wherein a buffer region (25) for a part (26) of the continuous film (12) is formed between the advance device (15) and the severing tool (20). ### Claim 3 (depends on 2) The device as claimed in claim 2, wherein between the advance device (15) and the severing tool (20), in a region of broad sides of the continuous film (12) there are arranged guide elements (21 to 23) for the continuous film (12), which are free of the buffer region (25). ### Claim 4 (depends on 3) The device as claimed in claim 3, wherein the advance device is a transport roller (15), in which cutouts (16) for the blisters (10) are formed. ### Claim 5 (depends on 3) The device as claimed in claim 3, wherein a shape of the stop (30) is matched on a side facing the continuous film (12), to a shape of at least one blister (10). ### Claim 6 (depends on 3) The device as claimed in claim 3, wherein the stop (30) is interchangeable. ### Claim 7 (depends on 2) The device as claimed in claim 2, wherein a shape of the stop (30) is matched on a side facing the continuous film (12), to a shape of at least one blister (10). ### Claim 8 (depends on 2) The device as claimed in claim 2, wherein the stop (30) is interchangeable. ### Claim 9 (depends on 2) The device as claimed in claim 2, wherein the advance device is a transport roller (15), in which cutouts (16) for the blisters (10) are formed. ### Claim 10 (depends on 1) The device as claimed in claim 1, wherein the advance device is a transport roller (15), in which cutouts (16) for the blisters (10) are formed. ### Claim 11 (depends on 1) The device as claimed in claim 1, wherein a shape of the stop (30) is matched on a side facing the continuous film (12), to a shape of at least one blister (10). ### Claim 12 (depends on 11) The device as claimed in claim 11, wherein the stop (30) is interchangeable. ### Claim 13 (depends on 11) The device as claimed in claim 11, wherein the advance device is a transport roller (15), in which cutouts (16) for the blisters (10) are formed. ### Claim 14 (depends on 1) The device as claimed in claim 1, wherein the stop (30) is interchangeable. ### Claim 15 (depends on 14) The device as claimed in claim 14, wherein the advance device is a transport roller (15), in which cutouts (16) for the blisters (10) are formed.
