Abstract
Abstract A multiple longitudinal traversing shed weaving apparatus comprises a weaving rotor having beat-up or beating elements for the inserted weft threads and shed-retaining elements which retain the warp threads, throughout a predetermined path, in their upper shed position or lower shed position. Each intermediate space between neighboring beat-up elements has operatively associated therewith a respective shed-retaining element which determines the upper shed position or lower shed position. Control means are arranged forwardly of the weaving rotor, viewed in the direction of travel of the warp threads, and serve for the lateral deflection and selective allocation of the warp threads at a shed-retaining element which determines the upper shed position or lower shed position. The control means possesses stroke adjusting elements in the weft direction which are constituted by rods or bars extending in the weft direction. These rods are connected with an actuation device of the type used in a conventional dobby loom.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
142 words
A multiple longitudinal traversing shed weaving loom comprising: a rotatable weaving rotor over which pass warp threads moving in a predetermined direction of travel; shed-retaining elements for holding the warp threads over a predetermined path in selective upper and lower shed positions for insertion of weft threads; control means arranged forwardly of the weaving rotor with respect to the direction of travel of the warp threads; said control means serving for the lateral deflection and allocation of each warp thread to a shed-retaining element which determines the upper shed position or the lower shed position; said control means comprising displaceable elements extending in the direction of insertion of the weft threads; and said control means further including an actuation mechanism with which there are operatively connected said displaceable elements for displacing the latter in said direction of insertion of said weft threads.
Claim 2
Dependent Claim
142 words
A multiple longitudinal traversing shed weaving loom comprising: a rotatable weaving rotor over which pass warp threads moving in a predetermined direction of travel; shed-retaining elements for holding the warp threads over a predetermined path in selective upper and lower shed positions for insertion of weft threads; control means arranged forwardly of the weaving rotor with respect to the direction of travel of the warp threads; said control means serving for the lateral deflection and allocation of each warp thread to a shed-retaining element which determines the upper shed position or the lower shed position; said control means comprising displaceable elements extending in the direction of insertion of the weft threads; and said control means further including an actuation mechanism with which there are operatively connected said displaceable elements for displacing the latter in said direction of insertion of said weft threads.
Claim 3
Dependent Claim
22 words
