The device serves to manipulate the healds or drop wires from their separation from a stack via the drawing-in of the warp threads up to the transfer to supporting members provided for arranging in a weaving machine and it contains holding devices for accepting the separated healds or drop wires and for positively transporting them to a drawing-in station and a transfer station, positioning elements arranged in the area of the drawing-in station, and transfer devices, arranged in the area of the transfer station, for transferring the healds or drop wires having a drawn-in warp thread to the supporting members. Consequently, only a single type of manipulating arrangement is required for manipulating the healds and drop wires from their separation up to the transfer to the supporting members. That results in a substantial reduction in potential sources of error and thus in the susceptibility to trouble. In addition, only two interfaces are necessary: one leading to the separating station and one at the transfer station leading to the supporting members.
Device for manipulating harness members in a warp-thread drawing-in machine from a place at which the harness members are separated from a stack to a place where the harness members are transferred to supporting members for being arranged in a weaving machine, comprising holding means for receiving separated harness members and for transporting them to a drawing-in station at which warp threads are drawn-in with respect to the harness members and a transfer station at which the harness members are transferred to the supporting members, positioning means arranged adjacent the drawing-in station for positioning the harness members to have a warp thread drawn-in, and transfer means arranged adjacent the transfer station for transferring the harness members having a drawn-in warp thread to the supporting members, said holding means including a movably driven endless member and spaced apart holding members mounted on the endless member for receiving a plurality of harness members, said endless member transporting the plurality of harness members received on the holding members to the drawing-in station and to the transfer station.
