Abstract
An apparatus is disclosed for lagging (in-process storing) packages of textile yarn on wheeled buggies. At least one storage lane for textile yarn buggies is provided and a plurality of wheeled textile yarn buggies with connecting hooks having depending tail portions for joining the buggies together as a train are positioned in the storage lane. Air switch pads are provided at the exit from the storage lane for detecting the presence of a buggy. A driven chain with lugs thereon for moving the train of buggies forward one buggy length and then engaging the depending portion of the hooks for disconnecting the buggy nearest the exit from the remainder of the train is actuated by a signal from the air switch pads each time the air switch pads fail to detect the presence of a buggy.
