Abstract
A device for the intermittent interruption of the embroidery needle movement on automatically controlled embroidery- or sewing- machines, particularly multiple head automation embroidery machines, with at least one needle bar, the latter being driven by means of a crank rod and a crank from a drive shaft. The crank rod is pivotally connected with a drive carriage. By means of a pawl the drive carriage can be connected with a driver which is fastened on the needle bar. The driver in its turn is able to be secured in an upper deadpoint position by means of a controllable holding pawl with the simultaneous separation or disconnection of the drive carriage.
