In a clip for closing a tubular wrapper, bag or the like, comprising a curved, U-shaped length of wire, which is adapted to be driven along a clip guideway by a punch against a die and thus closed around the gathered wrapper, the improvement which comprises forming each leg of the clip with an outwardly direct portion. A plurality of such clips are arranged one behind the other in a bar or stack. The bar is used in combination with the clip closing device including a clip guideway and comprising means for advancing said bar toward said guideway, a die for a clip in said guideway, and retractable punch for advancing a clip in said guideway toward said die, said punch having a pair of side portions with respective outwardly directed arcuate portions for receiving the outwardly directed portions of said legs of the clip, whereby upon retraction of said punch if the clip is not closed it will be retracted with said punch so as not to permit the next clip of said bar to be advanced toward said guideway. |
