Title: sewing machine
Inventor: TAKEI TATSUO
IPC: D05B27/04
Filed: 2019-06-20
Abstract: To provide a sewing machine to contribute to the reduction of vibration and noise.SOLUTION: In a sewing machine 10, a switching mechanism 80 is connected to a slide arm 60A of a transfer mechanism 60 in an upper feed mechanism 50. When the switching mechanism 80 is activated, the slide arm 60A is switched to a transmission state in which power from a driving cam 52 is transmitted to a feed link mechanism 61 or to a non-transmitting state in which the power from the driving cam 52 is not transmitted to the feed link mechanism 61. Therefore, when the switching mechanism 80 switches the slide arm 60A to a non-transmitting state, the operation of the feed link mechanism 61 is suspended and the vertical movement of an upper feed gear 77 is suspended. Accordingly, this contributes the reduction of vibration and noise of the sewing machine 10.SELECTED DRAWING: Figure 9
