Abstract
Apparatus for the individual control of the raising and lowering movement of warp yarns on a fabric weaving loom, in which the warp yarns are passed through guide eyes, these eyes being mounted on the piston rods of fluid pressure operated piston and cylinder jacks. There are a large number of jacks, these being grouped in a plurality of units which are removable and are juxtaposable with respect to number and position in accordance with the desired density of warp threads, the units being arranged in at least two tiers. This gives great flexibility of control.

An apparatus for the individual control of the raising and lowering of warp yarns of a fabric weaving loom, said apparatus comprising:
- a plurality of jacks, each of said jacks having at least one cylinder and one piston, said jacks arranged in groups as units with respect to one another;
- piston rods connected to said pistons on each said jacks;
- a warp yarn guiding eye mounted on each of said piston rods;
- a programmer for controlling the movement of said pistons, thus controlling the warp yarns for providing a desired pattern in the fabric;
- and said plurality of saidjacks being removable and juxtaposable with respect to position and number in accordance with a desired density of said warp yarns, and further arranged in at least two tiers, said tiers being in spaced elevational relationship to one another, above said warp yarns, such that said piston rods extend in a generally vertical direction.
