Abstract
A coupling device allows for the rapid releasable connection of harness cords to lifting cords on weaving machines. A first coupler is connected to lifting cords and a second coupler is connected to harness cords. An intermediate coupler is removable connected to the first and second couplers. The intermediate coupler allows for quick and easy, manual or automatic, coupling and decoupling of the first and second elements. The second coupling elements and the intermediate elements are adapted so that only the connection therebetween is breakable when pulling forces are exerted thereon.
Claims10
Connection apparatus for weaving machines comprising plural lifting cords, plural harness cords, plural first and second coupling elements, wherein the first coupling elements are connectable to the lifting cords for lifting warp threads on weaving machines, and the second coupling elements are connectable to the harness cords for lifting the warp threads, said connection apparatus further comprising intermediate elements including means for removably connecting to the first and second coupling elements, wherein said means provide for the connections of the intermediate elements with at least one of the first and second coupling elements to be breakable when pulling forces are exerted thereon for preventing damage through overloading.
A coupling method for connecting plural lifting and harness cords on weaving machines comprising providing first carriers and first couplers on the first carriers for carrying and presenting together the first couplers, connecting the first couplers to lifting cords, providing second carriers and second couplers on the second carriers for carrying and presenting together the second couplers, connecting the second couplers to the harness cords, providing intermediate couplers, and removably coupling the first and second couplers with the intermediate couplers.
