1. A mechanism for effecting guide bar lapping movement in warp knitting, said mechanism comprising:
- (a) a fluid drive servo motor means including a cylinder element and a double-acting, piston element arranged therein, one of said cylinder element or said piston elements being movable by fluid introduced into said cylinder, and control means for introducing fluid into said cylinder for causing selective movement of said movable element;
(b) rod means rigidly associated with said movable element for linear movement therewith; and
(c) connecting means for connecting said rod means to transmit directly said linear movement of said rod means to said guide bar, said connecting means including spherical bearing means interconnecting said rod means and said guide bar to permit said guide bar to make front and back swing movements with respect to said guide bar without affecting said direct transmission of said linear movement of said rod means to said guide bar.

Abstract
A mechanism for effecting guide bar lapping movement in warp knitting machines comprises a double-acting piston-in-cylinder servo arrangement connected directly to the guide bar. The piston 13 of the arrangement 11 may be connected by a rigid yoke arrangement 15 to a rod 16 slidable in linear bearings 17 and connected to the guide bar 12.

5. A mechanism for effecting the lapping movement of a plurality of guide bars in a warp knitting machine said mechanism comprising:
-
(a) a plurality of fluid drive motor including a cylinder, a double-acting piston arranged for movement within said cylinder, and a control means for introducing fluid into said cylinder for selectively moving said piston in both directions along the axis of said cylinder; (b) a plurality of rod means, each of which is rigidly associated with one of said pistons for movement therewith and each of which includes a slide rod mounted for linear slidable movement a bearing means, said plurality of slide rods all being arranged in close parallel relation to one another; and (c) a plurality of connecting means, each of said connecting means connecting one of said slide rods to one of said guide bars to transmit directly said linear movement of said slide rods to said guide bars for effecting said lapping movement thereof, said connecting means including spherical bearing means interconnecting said rod means and said guide bar to permit said guide bar to make front and back swing movements with respect to said guide bar without affecting said direct transmission of said linear movement of said rod means to said guide bar.

6. A mechanism for effecting guide bar lapping movement in warp knitting, said mechanism comprising:
-
(a) a fluid drive servo motor means including a cylinder element and a double-acting, piston element arranged therein, one of said cylinder element or said piston elements being movable by fluid introduced into said cylinder, and control means for introducing fluid into said cylinder for causing selective movement of said movable element; (b) rod means rigidly associated with said movable element for linear movement therewith, said rod means including a piston rod connected directly to said piston element and extending away from both ends of said piston element, a yoke connected to said piston rod, and a slide rod connected to said yoke and mounted for linear movement in bearing means; and (c) connecting means for connecting said rod means to transmit directly said linear movement of said rod means to said guide bar and to permit movements of said guide bar with respect to said rod means in directions of movement transverse to said linear movement of said rod means.

7. A mechanism for effecting the lapping movement of a plurality of guide bars in a warp knitting machine said mechanism comprising:
-
(a) a plurality of fluid drive motor including a cylinder, a double-acting piston arranged for movement within said cylinder, and a control means for introducing fluid into said cylinder for selectively moving said piston in both directions along the axis of said cylinder; (b) a plurality of rod means, each of which includes a piston rod connected directly to said piston for movement therewith with said piston rod extending away from both ends of said piston, and each of which includes a yoke connected to said piston rod and a slide rod connected to said yoke and mounted for linear movement in bearing means, said plurality of slide rods all being arranged in close parallel relation to one another; and (c) a plurality of connecting means, each said connecting means connecting one of said slide rods to one of said guide bars to transmit directly said linear movement of said slide rods to said guide bars for effecting said lapping movement thereof and to permit movements of said guide bars with respect to said slide rods in directions of movement transverse to said linear movement of said slide rods.
