Abstract: Machine à coudre entraînée par un moteur dans laquelle un arbre de couture (11) est entraîné en rotation par un moteur (14) de manière à entraîner avec un mouvement alternatif une aiguille de couture (1). Dans une machine à coudre dont l'arbre de couture (11) entraîne l'aiguille (1), un cadre de couture (10) tourillonne de manière rotative l'arbre (11) et le moteur (14) entraînant l'arbre (11), le rotor (40) du moteur est monté sur l'arbre (11) et le stator (38) du moteur est monté dans le cadre (10). Ainsi, des parties telles qu'une courroie ou des poulies qui étaient nécessaires auparavant pour transmettre la puissance de traction du moteur (14) à l'arbre (11) à côté du cadre (10) sont superflues, ce qui permet de simplifier la structure de toute la machine et d'en réduire le coût.

Abstract: This invention relates to a method and apparatus for electronically gearing the sewing parts of a sewing machine (10), and more particularly it relates to electronically gearing the bobbin (22, 24) to the needle (12, 14) to eliminate the necessity of their physical coupling through mechanical linkages and drive shafts. Servo motors (26, 28, 30) provide torque to the needle, bobbin, and various other sewing parts of the sewing machine which require concerted movement. A computer (102) uses servo motor positional information to calculate motion commands that are sent to the needle and bobbin servo motors (26, 28, 30), thereby enabling electronic gearing of the bobbin (28, 30) to the needle (12, 14) so that each moves substantially in unison. Motion commands sent to servo motors (50, 52) attached to various other sewing parts of the sewing machine are based on servo motor positional information to enable the sewing parts to move in concert with the needle and bobbin. Servo motors (50, 52) move the sewing material in two dimensions during stitching, and each move of the sewing material is calculated to consume the maximum amount of time available between stitches in order to dampen acceleration and deceleration of sewing parts and eliminate problems associated with machine jerk.

Abstract: A variable stroke drive system (10) for a tufting machine (T) includes a series of drive assemblies (40) mounted along the frame of the tufting machine (T). Primary drive shafts (41A, 41B) extend through the drive assemblies (40) and are each driven by a drive motor (46). A series of first drive members (55A, 55B) are mounted to the primary drive shafts (41A, 41B) and are linked to associated second drive members (60A, 60B) such that the driving of the first drive members (55A, 55B) by the primary drive shafts (41A, 41B) in turn drives the second drive members (60A, 60B). Cam arms (65, 66) are connected to the second drive members (60A, 60B) and to rocker arms (68) to which push rods (85) are mounted, the cam arms (65, 66) being vertically reciprocated by the rotational movement of the second drive members (60A, 60B) so as to drive the reciprocation of the push rods (85), and thus the needle bar(s) (11, 11') connected thereto along a desired stroke or reciprocating path of travel. Controlling the rate at which the primary drive shafts (41A, 41B) are driven enables control of the stroke of the needle bar(s) (11, 11').
