Abstract
In a sewing machine, a needle-bar is slidingly mounted in two bearings, the external surface of each of which has a spherical profile. The bearings are pivotably engaged in respective seats of complementary profile provided in a fixed support, for an upper bearing, and in a movable lever, for a lower bearing. This lever is alternately pivoted into two opposite positions under the action of a stepper motor. The motor drives the movable lever by engagement of a pinion with peripheral gear teeth carried by the movable lever. The motor, the fixed support, the movable lever, the bearings and the needle bar form a self-contained and detachable assembly.
