Abstract (en)
[origin: EP0337079A2] According to the invention, winding machines having supporting rollers are so arranged that wound rolls (17) of small diameter can be ejected by being clamped between the ejection surface (13) of the ejector bar (9) and the supporting roller (2), which carries out the ejection, and by being lifted out of the supporting-roller bed (3) by a rotary movement of said supporting roller (2). In such a winding machine according to the invention, this is made possible in that the ejection surface (13) reaches the swung-round supporting roller (1) and in that its upper limitation in the swung-forward position extends as far as the region of the crown of the adjacent supporting roller (2). <??>In a winding machine of this type comprising a combined device (8) for ejecting wound rolls and for inserting new winding tubes (5), in which the ejection surface (13) of the ejector bar (9) ends at a distance from the supporting roller (1) and the tube-inserting element (14) releases the tubes (5) through the free space between the ejection surface (13) and the supporting roller (1), the ejector bar (9) has an ejection surface (13) which can be moved or extended in the rest position of the ejecting/inserting device (8) in the direction of the swung-round supporting roller (1). <IMAGE>
