Abstract
In order to reduce the impact speed of a latch () of a needle () in back position by reducing the acceleration effect originating from a half stitch (), the upward jaw slope () of the needle () is subdivided into different regions. A first section () ascends at a relatively large acute angle γ of, for example, up to 20°, preferably 16°. Just after the half stitch () has contacted the inside () of the latch (), said half stitch arrives on a second section () of the upward jaw slope (). The second section () is a straight section which ascends at a smaller acute angle β of, for example, only 14° or less. Consequently, an acceleration effect from the half stitch () on the latch () is avoided over a wide pivot range of said latch. Preferably, this acceleration-free pivot range is at least 90°, preferably greater than 110°.
