Abstract (en)
[origin: EP0054973A1] 1. Apparatus for making rolls of shingled strip (37) of flat flexible articles, such as sacks or sack workpieces, which are deposited in a shingled arrangement on a belt conveyor (28), comprising a reel hub (45), which is mounted in the machine frame (54), and to which at least one retaining strip (40) is secured, which is withdrawn from a supply roll (39) and during the winding of the shingled strip is held under tension against the shingled strip to retain the same, a belt conveyor for supplying the workpieces, which consists of a frame, which carries rollers (32, 33) at least at opposite ends and is pivoted on the axis of the first roller (32), and a driven endless conveyor belt (28) trained around the rollers of said frame, also comprising a device (38) for moving the frame into engagement with the reel hub (45) or with the roll of shingled strip (37) being formed on said reel hub so that the reel hub roll is driven by the endless conveyor belt (28), and a conveyor for delivering the shingled articles to the belt conveyor, characterized in that two pivoted arms (47, 49) arranged with mirror symmetry are longitudinally slidable mounted on an axle (53), which is transverse to the belt conveyor (28), each of said pivoted arms carries at its end an outwardly directed pin (46, 50) for receiving a reel hub (45), and the pins (46, 50) are used in alternation for receiving the reel hub (45) for the roll (37) to be wound at a time, which reel hub is aligned with the belt conveyor (28), and for a replacement of the completely wound roll of shingled strip (37) by a new reel hub (35).
