摘要： 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').

摘要： The invention relates to a sewing machine (10). The sewing machine (10) includes a main shaft which is rotated by a motor (1) to move a sewing needle, a position detecting means (14, 15) for detecting a rotation angle of the main shaft as a main shaft angle, a thread cutting mechanism (30) having a movable knife (31), a thread cutting cam (51) having a cam groove (51a) formed along a circumferential direction and rotating in synchronization with the rotation of the main shaft, a cam follower (52) configured to engage with the cam groove (51a) to move the movable knife (31) in accordance with the cam groove (51a), a thread cutting actuator (56) which switches the cam follower (52) between an engaging position and a disengaging position with respect to the thread cutting cam (51), and a control means for controlling the thread cutting actuator (56) and the motor (1). The control means includes an operation timing determining means for determining an operation start timing of the thread cutting actuator (56) or the motor (1), based on at least one of a rotation speed (v1, v2) of the motor (1) for a thread cutting operation and a main shaft stopped angle (θ1) at which the main shaft has stopped immediately before the thread cutting operation.

摘要： The invention relates to a sewing or knitting machine, comprising a needle, a gripper and a workpiece-advancing device with at least one driven advancing element. Said advancing device (15) has a linear drive for driving the advancing element (14). The linear drive has two armatures (25, 26) which can be driven in different directions. A control device (47, 51) with a control circuit (49) for the horizontal movements and a control circuit (50) for the vertical movements of the advancing element (14) is allocated to the advancing device (15) and both control circuits (49, 53) are subordinate to a main control device (6) comprising a data processing device (7). Said main control device (6) receives its synchronisation impulses from an encoder (5) according to the current position of the needle or the gripper. The actual values (48, 52) of the horizontal and/or vertical movements of the advancing element (14) can be supplied to the main control device (6) at option.

Beschleunigungsprofil ausführt.
