Abstract
An improved weaving loom provides for mounting of the shuttle box assemblies and shuttle picking apparatus at any of a plurality of positions along the shuttle raceway to enable the loom to be configured to have a weaving width substantially narrower than the total width of the loom raceway.
Claims15
In a loom having a shuttle raceway extending across the weaving path of the loom between opposite ends of the loom weaving surface and in which a shuttle moves reciprocatingly across said raceway between two multiple cell shuttle box assemblies, said shuttle being propelled by picking apparatus positioned adjacent each said shuttle box assembly, each said multiple cell shuttle box assembly having a plurality of shuttle cells with each said cell being mounted for selective movement between a position in alignment with the path of a shuttle moving along said raceway and at least one position out of alignment with the path of said shuttle along said raceway, said loom including support structure for carrying said raceway, said shuttle multiple cell box assemblies and said picking apparatus, the improvement comprising.
- said loom being configured for mounting said multiple cell shuttle box assemblies and said picking apparatus at any of a plurality of positions along said raceway, whereby the loom may be configured to have a waving width substantially narrower than the total width of the raceway for weaving a fabric substantially narrower than the total width of the raceway.
For a loom having a shuttle race and at least one shuttle box cell on one side of the weaving path of the loom and a plurality of shuttle box cells on the other side of said weaving path for receiving and launching shuttles along the shuttle raceway, a rotary shuttle box changing apparatus comprising
- a rotary drive having a rotary motion output member rotatably driven to predetermined angles of rotation about an axis extending through said output member;
- said plurality of shuttle box cells being mounted to said rotary motion output member at spaced locations about said axis, such that predetermined rotation of said output member about said axis will being a selected one of said shuttle box cells into potion for alignment with said shuttle raceway for receiving and launching a shuttle along said shuttle raceway;
- and
- a shuttle box drive support carrying said rotary drive and being attachable to said loom, said shuttle box drive support comprising means for moving said rotary drive preselected distances toward and away from said shuttle raceway, whereby movement of the rotary drive away from the shuttle raceway provides for space between the shuttle boxes mounted to the rotary drive output memeber and the shuttle raceway to facilitate desired rotation of the output member and shuttle box cells and movement of the rotary drive toward the shuttle raceway will bring a desired shuttle box cell into alignment with the shuttle raceway for receiving and launching a shuttle.
