摘要： The device (1) comprises a support (2) for a sliding rod (11) subjected to the force of a spring (12) tensioned between a block (11a) and a needle-clamp (9). The rod carries a casing (13) enclosing two slides (17 and 18) of which one (17) carries a hook (20) and the other slide (18) carries a sleeve (18a). A control lever (23) hinged to the casing and subjected to the force of a second spring (25) holds the slides (17 and 18) in a retracted position of the hook (20). The lever (23) comprises two sides (23a, 23b) having each a cam (21, 22) cooperating with sensors (15b, 16b) which are carried by two connecting parts (15, 16) hinged to the casing (13) and to the slides (17, 18). The cams (21, 22) determine the sequence of the motion of the slides in the casing (13), their amplitude and nature of their displacement during the rocking of the lever (23) against the force of the spring (25) so as to guide the hook from its retracted position to a position where it goes through the needle eye in order to catch a yarn placed on a portion (23e) of the liver (23).
