Abstract: A plastic reinforcement engaging the end wall of a bag tube includes an outlet surrounded by an outwardly extending flange which has the same curvature as the end wall and extends. This construction stiffens the stiffens the end wall and reduces the risk of the tube tipping over which it is rested upside down on its cap.

Abstract: Apparatus for transporting work pieces by means of work piece pickups engageable with a chain type conveyor to a plurality of work stations located along the path of the conveyor. Work piece pickups located between parallel spaced guide rails which are disposed above two parallel spaced endless link type chains are provided with guide rolls which engage the undersides of the guide rails and with pivotally mounted carrier arms provided with toe portions adapted to engage the links in the conveyor chains. Means are provided at each work station to stop one, or a group, of work piece pickups while the conveyor chains continue to move and to actuate a gripping device for releasing the work piece so that it can be worked on.
