ABSTRACT:
In processes and apparatuses for closing packaging sheaths made of flexible material, particularly tubular bags, by means of a U-shaped closing clip 4, the end portion 5 of the packaging sheath which is to be closed is gathered and is introduced into a receiving space 7 between the guideways 2 for the two legs of the closing clip 4 and for a closing punch 3 and by means of said punch is closed on a female die 9 at the end of the clip-guiding guideway 2, the problem arises that particularly with bags having a highly fluid content it is complicated to feed the gathered end portion 5 of the packaging sheath to be closed laterally to the clip-guiding guideway 2 and is particularly difficult to remove the closed bag. In order to avoid said difficulties it is suggested that the bag to be closed is moved along a straigt line into an open receiving space 7 between the guideways 2 for the two legs of the closing clip 4 and that the female die 9, which is disposed laterally of the end of the clip-guiding guideway 2 is moved at right angles as far as to its closing position in a guiding groove 8 along a straight line.
