    A gripper tape drive device for a shuttleless loom, in which a circular disc is mounted coaxial but not perpendicular to the main loom shaft, its outer circular edge rotatably engaging a circular collar, of which two opposing pins spaced 180 DEG apart cooperate with the ends of a fork rigid with the control shaft of the gripper tape sprocket. Adjustment means are also provided for varying the amplitude of the oscillatory motion of said control shaft.

    The invention relates to textile machinery and relates to flexible rapier weaving machines, namely a flexible rapier drive.
    The purpose of the invention is to simplify the design and expand the technological capabilities.
    In Fig.1 schematically shows the drive, a perspective view; figure 2 - section aa in figure 1
    The drive contains the main shaft 1 of the weaving machine, rotating at a uniform angular speed in the direction of arrow 2, and a control shaft 3 associated with it, the axis of which is perpendicular to the axis of the main shaft 1, and the axes of these shafts intersect at point 0. On the shaft 3 the toothed sector 4 of the overdrive is fixed, which also contains gear 5, which engages with sector 4 and is rigidly connected to the shaft 6 located parallel to the control shaft 3 and rigidly connected to the drive sprocket 7 driving the rapier 8, supplied for all th its length 1 perforations 9 and a gripper 10 at one end,
    The control shaft 3 and, consequently, the sprocket 7 receive oscillatory movements in the direction of arrows 11, as a result of which the gripping device 10 makes a reciprocating rectilinear motion in the direction of arrows 12.
    To do this, an extension 13 is provided at one end of the main shaft 1, containing a hemispherical recess 14 with a center at point 0, which includes a hemisphere 15 also centered at point 0, forming one unit with the annular disk 16, which is coaxially fixed to the main shaft 1 with screws 17 and the hemispherical clamping lid 18, so that its center of symmetry coincides with the point O and its plane 19 of symmetry is not perpendicular to the axis of the main shaft 1, but at an angle y to the plane 20, perpendicular to shaft axis 1 Outer ring lip The annular disk 16 interacts with the annular groove of the cylindrical sleeve 21, and the sleeve 21 has on its outer surface two pins 22 and 23 spaced 180 ° apart from each other, respectively, and located on a common axis 24 passing through point 0 and forming an angle & Ј with the plane 19 of the disk symmetry. The pins 22 and 23 interact with the ends of the plug 25, which is rigidly connected to one end of the control shaft 3.
    The stroke of the gripping device depends on the angle y, as a result of which, to change the stroke of the gripping device, it is only necessary to change the angle of inclination of the annular disk 16, i.e. angle $. For this purpose, the hemisphere 15 is blocked in the recess 14 by means of screws 17, which pass through the elongated adjustment slits 26 arranged parallel to each other in the hemisphere 15. The hemisphere 15 is directed, at its movement, to the desired angular position with a finger 27 protruding from the hemispherical grooves 14 and entering the guide groove 28, made on the outer surface of the hemisphere 15 "
    To achieve this adjustment, the guide groove 28 and parallel slots 26 must be located in planes parallel to the plane passing through the axis; the main shaft 1 and perpendicular to the end of the annular disk 16, restored from the center of the latter.
    The drive works as follows
    Continuous rotation of the main shaft 1 forces the hemisphere 15 rigidly connected to the shaft to rotate and drive the annular disk 16 with a constant amplitude from the plane 19 to the plane 29 symmetrical to the first relative to the plane 20.
    The cylindrical sleeve 21, which does not rotate with the shaft 1, since it is rigidly connected to a fork 25 located perpendicular to the axis of the main shaft 1, oscillates with the same amplitude, which is converted into the corresponding reciprocating motion of the control shaft 3 and reciprocating duck laying pick-up
