Abstract
Abstract The apparatus is associated with a spinning or twisting machine and removes individual textile bobbin tubes from a reservoir, such as a container which contains such bobbin tubes. The container has in its lower portion a funnel-shaped structure through which the bobbin tubes move downwardly towards an opening. As is known, there is the danger that the bobbin tubes undesirably form "bridges" and thereby the further delivery of such bobbin tubes is interrupted. Such bridge formation is avoided by providing a break-up rod or bar which is arranged substantially horizontally and parallel to the broad sides of the container, in the interior and in the region above an opening of the container. The break-up rod or bar is supported in the longitudinal sides of the container with play on all sides and in a freely rotatable manner. The thickness of the break-up rod or bar and the thickness of the bobbin tubes are of the same order of magnitude. This apparatus has the advantage of surprising simplicity and thus is much less expensive than hitherto known devices.
