摘要： A sewing machine which may employ a loop-making hook rotating about a vertical axis employs a one-way bobbin and bobbin case. A bobbin can have a larger flange and a smaller flange so as to fit in a suitably configured bobbin case in only one way. The bobbin may have a blind axial opening with a guide groove to fit a winder spindle in only one way so that the bobbin can only be wound in one way. Attempts at incorrect orientations cause the bobbin to protrude from the bobbin case in an obviously incorrect manner. Inadvertent efforts to wind the bobbin incorrectly are likely to be fruitless. Thus, a user can readily install the bobbin in the bobbin case with a proper orientation and with the thread correctly wound. Surprisingly, stitching problems, such as poor seams or the like, can be reduced.

摘要： The present computer-controlled electric sewing machine wherein the rotational speed of the central drive motor (M) is servo-controlled by means of a regulating circuit (O, CL, Cs) including a tachymetric control generator (G) has a mechanism for driving a support of a cop (C) to be reeled, comprising the assembly of structural elements of the generator (G), a double-acting clutch device (EA) enabling mechanical connection of the rotor of the generator (G) either to the central motor (M) or to the cop support, electric switch means (IE, IG) providing for in the latter case the connection of the armature of the generator (G) to an electric supply source (A) while preventing current from being supplied to the central control motor (M) of the machine.
