    Abstract: An existing tying machine (20) is modified by the addition of components to produce a self contained laundry tie-out station (10). The components for the modification include a linear slide support yoke frame (22), attached on top of the tying machine's component mounting platform (24) with a pneumatic linear slide unit (34) mounted on top. A hanger slide rod assembly (40) is attached to the mounting face of the linear slide unit for retaining a selected group of hangers (36) containing laundered clothing (36?). Conveyer feed lines are aligned with distal ends of the recessed hanger slide rod (42) when in an at rest position. A pneumatic system operates the slide unit and controls are integrated into the tying machines existing electrical system. The invention draws the group of hangers into the tying machine where it bunches the hangers together and electromechanically binds the group with a twist tie.
