A device for clamping and guiding crocheting needles for a crocheting machine. On the one hand a clamping device for the crocheting needles and on the other hand a knock-over comb are to be created, which permit a very fine spacing. To this end, in the bottom part (27) and in the clamping cover (29) of a clamping device (12), opposite, straight needle beds (73, 74) are arranged closely together. The needle beds (73, 74) have wall surfaces that are inclined in a V-shape. A knock-over comb (20, 80) fixed to the machine has upwardly projecting teeth (86) for the crocheting needles. The spacing of the needle beds and guide elements is at least 12, in particular 14 per centimetre of machine width. The holding bar (23) fixed to the machine and the bottom part (27) of the clamping device (12) have recesses, in particular chamfers (77, 76) that face one another, which permit the clamping device to move to close to the teeth (86).

Dispositif pour fixer et guider les aiguilles d'une machine à crocheter. Un dispositif de fixation pour les aiguilles à crocheter et un peigne d'abattage assurent un espacement très précis. Dans la partie inférieure (27) et dans le couvercle (29) du dispositif de fixation (12), du côté opposé, des fontures (73, 74) sont disposées l'une près de l'autre. Les fontures (73, 74) comportent des parois inclinées formant un V. Un peigne d'abattage (20, 80) fixé à la machine comporte des dents orientées vers le haut (86) pour les aiguilles à crocheter. L'espacement des fontures et des éléments de guidage est d'au moins 12, surtout de 14, par centimètre correspondant à la largeur de la machine. La barre d'appui (23) fixée à la machine et la partie inférieure (27) de dispositif de fixation (12) comportent des rainures-guides, plus précisément des chanfreins (77, 76) se faisant face et permettant au dispositif de fixation de se déplacer pour se refermer sur les dents (86).
