Abstract
A latch needle (1) having on its latch (7) a latch head (9) that is provided with a recess or a depression (12) for receiving a section of a tip (14) of the hook (4), said tip having the configuration of a truncated cone. The latch head (9) is wider than the latch shaft (8) of the latch (7), however, distinctly narrower than the needle shaft (20). Due to this measure, too great an expansion of the loops during the casting-off process is avoided, and the risk of a collision of the latch head with other components, for example, sinkers, is reduced.
Claims16
Latch needle (1) for a loop-forming textile machine, such as, for example, a knitting machine, comprising
- a needle body (2) having a needle shaft (20) with a shaft width (11), said shaft width to be measured between a first lateral surface (18) and a second lateral surface (19), and having a loop-forming part (3) with a hook (4) and a latch slit (5), and with a bearing arrangement (6) located in the latch slit (5),
- a latch (7) having a latch shaft (8), which is pivotally supported on the bearing arrangement (6) and bears a latch head (9) being provided with a receiving space (12) for receiving the tip (14) of the hook and having a width (16) that is to be measured between a first lateral surface (21) and a second lateral surface (22),
- whereby the latch (7) is supported so as to be pivotable between a rear position and a closed position,
- whereby, in the closed position, the latch head (9) has a receiving space (12) that interacts with the tip (14) of the hook (4) in order to form a hook inside space (10),
- characterized in that the width (16) of the latch head (9) is smaller than 95% of the width (11) of the needle shaft (20).
