ABSTRACT:
A heald singularizing system includes a selecting member (21) for the healds (LI) fed in the form of a stack (LS). The selecting member (21) separates the front-most heald (LI1) from the stack and makes it available for the drawing-in of the warp threads. The selecting member (21) is formed by a piston which can perform a stroke essentially transversely to the heald stack (LS), during which the heald (LI1) is displaced from the heald stack (LS) into an intermediate position (ZP). Transfer means (24) transfers the respective heald (LI1) from its intermediate position (ZP) to a transport unit (25) for taking it to its drawing-in position. All types of healds can be selected from the heald stack, and neither a special preparation of the healds nor the use of a special type of heald is necessary. The heald separation and the further removal are completely uncoupled, to permit the use of means optimally adapted to the individual functions and also to simplify considerably the rectification of faults.
