Abstract
A pulley-block drive of an open shed Jacquard mechanism is sectionally controlled by a movable suspension apparatus. Pulley bands or harness cords are attached to one of the ends of the movable suspension apparatus. The movable suspension apparatus is suspended from hooks which can engage with the knives of the jacquard machine so that the movable suspension apparatus is driven by the knife grid of the jacquard mechanism.
Claims13
Jacquard loom machine apparatus comprising movable suspension apparatus and moving means for moving the suspension apparatus by knife grids of the jacquard machine apparatus, the moving means comprising hook means and connecting means for connecting the hook means to the movable suspension apparatus, hook-shaped projection means on the hook means and lateral moving means for moving the hook means laterally for selectively engaging and disengaging the hook-shaped projections with the knife grids;
- wherein the hook means comprise flat strips aligned next to each other and wherein the hook-shaped projections are provided on flat sides of the flat strips;
- wherein further the lateral moving means comprise needle means having their first and second opposite rollers contacting opposite flat faces of each strip, the rollers being connected to the needle means for moving horizontally with the needle means, whereby portions of the strips are moved laterally with the needle means and the rollers for selectively engaging and disengaging the hook-shaped projections with the knife grids.
Jacquard loom apparatus comprising:
- movable horizontal support boards;
- vertical movable hooks and means for connecting the hooks and the support boards, each of the hooks having hook-shaped projections extending laterally from the hooks;
- and
- horizontally movable needles and means for connecting the needles which the hooks for moving the hook-shaped projections selectively into and out of engagement with knife grids;
- wherein the hook means comprise flat strips having relatively wide dimensions transverse to a direction of needle movement and relatively narrow dimensions parallel to the direction of needle movement and wherein the means for connecting the needles to the strips comprise rollers connected to the needles and positioned on opposite sides of the strips for rolling along flat faces of the strips and for moving the strips horizontally with movement of the needle, while permitting flexing of the strips.
An open shed jacquard machine comprising:
- a plurality of pulley bands, hooks, knives, harness cords, and a movable suspension apparatus and a fixed suspension apparatus;
- wherein one end of each pulley band is connected to one hook and the other end of each pulley band is connected to a movable suspension apparatus, while one end of each harness cord is connected to a harness and the other end of the harness cord is connected to a fixed suspension apparatus, so that all pulleyblocks can be sectionally controlled, and each movable suspension apparatus is driven by a knife grid of the jacquard machine;
- wherein further each movable suspension apparatus is suspended from a number of hooks which can engage with the knives, each hook having the same form as the hooks to which the pulley bands are affixed and each hook consisting of two strips aligned next to one another each of which are provided at the appropriate height with a hook-shaped projection and each strip being pivotally attached at its base with the movable suspension apparatus and slides at its top in a guide, which permits a certain deflection of an upper end of the strip.
