A process and a device enable tubular straps to be pulled or guided through support roller stations. The strap is rolled until the diameter (D) of the roll is less than the operating diameter (D') and is held in this position by a clamping means which moves with it, such as a mesh sleeve. The desired diameter of the strap is obtained by means of a device whose diameter decreases like that of a nozzle.

A conveyor having a roller belt closed in the circumferential direction having overlapping belt edges and an outer circumference and a plurality of belt support rollers guiding the roller belt along a conveying path, each support roller having a running face in contact with the outer circumference of the belt, each support roller defining an overlap with the next following support roller in the circumferential direction so that an imaginary axial extension of its running face intersects the running face of the next following support roller. Each overlap being oriented in the same direction so that in the event the belt rotates in the direction of the circumference, the outer edge of the belt in the overlap region contacts the running face instead of touching the edge of the following support roller.
