This invention relates to a roller arrangement for feeding a material roll in an industrial machine forwards, preferably a roll in a cellulose or paper industry machine, the roller arrangement having such a design that it does not only feed the roll forwards but can also control the same laterally. According to the invention, the roller arrangement is characterized by the combination of the following features: a transverse roller (1), which is driven, is intended to be in contact with the material roll on its underside for feeding the same forwards, the roller having a width which is at least as great as the width of the roll; the roller (1) is intended to cooperate with contact means (3), which are arranged on the topside of the roll and are borne by a horizontal girder (4), which is arranged over and essentially parallel with the roller (1), the contact means having the purpose to force the roll against the roller; guide means (14-16) are suspended in the girder (4) and are intended to be in contact with the roll (2), the guide means (14-16) being arranged in that way that they can lift the girder (4) and by that the contact means (3) in order thereafter to be able to control the roll laterally. |
