摘要:
Drive unit for a weaving loom which comprises a main shaft (21) operating the essential weaving devices (27) of the loom, a driven shaft (25) operating a weave machine (26), and a single electric motor (20) for loom operation. The electric motor (20) is connected to said main shaft (21) through a first synchronous gearing comprising a disengageable clutch (28), and to said driven shaft (25) through a second synchronous gearing in constant mesh. Detection (29a, 29b, 29c, 32) and control (30, 31) devices are provided to allow engaging said clutch (28) in any preset angular position.

The invention relates to a gripper-opening device for grippers of a weaving loom, comprising a shaped-profile slider (3), capable of engaging with an operating lever of a weaving gripper and movable at least in a direction parallel to the motion of the gripper by means of a driving motor (8), between said motor (8) and the slider (3) there being provided connection means (4, 5, 6, 7, 9) in the form of an exact straight-line guide mechanism (7) whose control pin (9) is pivoted to a base (4) rigidly linked to the slider (3).
摘要:
A device for controlling the working speed of a loom, during the starting run of the loom, wherein the motor section of the loom comprises a double-speed motor. A first lower speed is equal to the steady speed of the loom; a second higher speed is equal or higher than a predetermined launching speed. During the starting run, the instantaneous speed of the motor is continuously monitored and the motor section is connected, through a main clutch group, to the weaving section of the loom, in a rest state, when said speed is equal to a predetermined launching speed.
摘要:
A control mechanism of a heald frame in weaving looms is disclosed, of the type comprising a frame hinged to an articulated linkage capable of converting the substantially rectilinear motion of a control bar (B) into a vertical motion of the frame, characterised in that said bar (B) is provided with a permanent magnet body (M) and in that an electric-coil structure (C) is further provided, in whose proximity said magnet body (M) is intended to slide, fixed in respect of the loom and forming the armature of a linear electric motor of which the magnet body (M) represents the mobile part. Some preferred arrangements of a plurality of such mechanisms in a weaving loom are further disclosed.
