A push rod (38) with a pick-up hook (38A) at the end is moved in an axial plane of symmetry to engage by means of the pick-up hook in an intermediate position the partial initial courses (M1) of a pocket (M2) and to bring them progressively to the side opposite the arc of working needles with the progressive formation of the fabric; a body in the form of a shaped annular ring (18), disposed inside the needle cylinder, has a radial slot (22) for said push rod (38) and radial slots (24) in the area opposite said arc of working needles; hooks (60) movable in said slots (24) can be moved from a concealed position to a raised position to make pin-shaped appendages (62) penetrate into the fabric along the initial edge (M1) when this has been brought by the push rod (28) to the side opposite that of the arc of working needles, and subsequently to move the initial courses (M1) progressively up to the needles which are raised and inserted into the fabric to engage said edge (M1).

Une tige formant poussoir (38) dont l'extrémité est en forme de crochet de préhension (38A) se déplace dans un plan axial de symétrie de sorte que le crochet saisisse en une position intermédiaire les rangées initiales partielles (M1) d'une poche (M2) pour les amener progressivement vers le côté opposé à l'arc d'aiguilles actives au cours de la formation progressive du tissu. Un corps annulaire profilé (18) à l'intérieur du cylindre à aiguilles possède une fente radiale (22) pour ladite tige formant poussoir (38) et des fentes radiales (24) dans la zone située en face dudit arc d'aiguilles actives. Des crochets (60) montés mobiles dans ces fentes (24) peuvent se déplacer entre une position escamotée et une position soulevée afin de faire pénétrer dans le tissu des éléments rapportés saillants (62) le long du bord initial (M1) une fois que celui-ci a été amené par la tige formant poussoir (28) vers le côté opposé à l'arc d'aiguilles actives, et afin de déplacer par la suite progressivement les rangées initiales (M1) jusqu'aux aiguilles, qui sont relevées et introduites dans le tissu en vue de saisir ledit bord (M1).
