Abstract
The cutting needle (1) according to the invention is, for example, a latch needle and has a knife element (11) secured to the shank (2). The knife element (11) defines a cutting edge (18) which projects obliquely upward from the shank. The knife element (11) is arranged externally of the range of motion of the latch (4) and cuts open a loop situated on the shank when it is overdriven outward. The knife element (11) is made, for example, of a suitable spring steel and is held unremovably on the shank (2).
Claims7
A cutting needle for loop-forming textile machines, comprising a shank provided at one end with a hook and, a separate knife element secured to the shank wherein the knife element has a cutting edge which is rising at an inclination relative to the longitudinal direction of the shank and is disposed in a recess formed in a side face of the shank, and further comprising a slider element mounted on the shank for movement in a longitudinal direction of the shank and having an edge facing the hook end of the shank that is approximately perpendicular to a top surface of the shank and which in a first position will effectively cover the cutting edge and in a second position will expose the cutting edge, whereby the needle can be selectively used as either a cutting needle or a transfer needle.
A cutting needle for loop-forming textile machines, comprising a shank provided at one end with a hook and, a separate knife element secured to the shank, and wherein the knife element is formed as a transfer spring that is secured in a recess formed on a side face of the shank, and has a cutting portion and a transfer portion spaced from the cutting portion in the longitudinal direction of the needle.
