Especially, be with 30 to contact with main calender 22 at contact site at least, in the sector of circumference, move, with shaped region 20 relative positionings, wherein said shaped region is relative with secondary calender 24.

Preferably, calender has different diameters, and especially, main calender has the diameter littler than secondary calender.For example, the diameter of main calender is 0.1 to 0.4 with the ratio of the diameter of secondary calender, is preferably 0.2 to 0.3, preferably equals 0.27.

In addition, preferably, device 1 comprises can be at the shaping adjustment of the volume tension-adjusting gear with 30 tension force.

For example, the tension adjustment apparatus comprises idler roller 40, said idler roller be with 30 to engage, have movable rotation, thus with tractive or unclamp said band and adjustment of tonicity.

According to preferred embodiment, with the closed circuit of 30 formation around main calender 22.For example, aligning roller 12 is positioned at by the inboard of being with the circuit that forms with idler roller 40.

With 30 formed at least a portion that is used for this circuit the volume conveyer.

Device 1 also comprises the guiding device of the volume that is used to guide said pipe or is forming.

For example, said guiding device comprises carriage, and this carriage comprises a pair of plate 52, this a pair of plate along the rotation positioned at intervals of calender 22,24 so that between this is to plate, define a zone.

When the shaping of volume at first, the pipe T that also not have twine to go up to roll up is positioned in the shaped region 20 between the plate 52 of guiding device.

Carriage also comprises first telecontrol equipment, and said first telecontrol equipment is connected to plate 52, so that on the shaping direction, move these plates.For example, said telecontrol equipment is pneumatic.

According to an embodiment, device 1 comprises the band storing apparatus, and said band storing apparatus comprises for example a pair of flange 200, and each flange all is coupled on the side of main calender, from the radial surface of said main calender give prominence to.In said embodiment, said band is narrower slightly than the axial dimension of main calender, and keeps being accommodated between the flange.

According to another embodiment, said band has the width bigger than the axial dimension of main calender, so as outstanding from the edge of said main calender, but be slightly smaller than the axial distance between the plate 52.

Advantageously, hang over the edge of said band and the problem between the plate 52 with regard to having limited fiber like this.

According to preferred embodiment, saidly that is to say with 30 being multi-layered types, form by a plurality of overlapping layers.

Preferably, comprise with 1 that the outer surface 30a ' of machined layer 30a, said machined layer is predetermined and contact, and process, and be smooth with inviscid by polyurethanes (polyurethane) with netting W.

In addition, be with 30 to comprise middle enhancement Layer 30b, for example process, and be positioned on the inner surface of machined layer 30a by polyester (polyester).

In addition, be with 30 to comprise traction layer (dragging layer) 30c, said traction layer is arranged to contact with enhancement Layer 30b and is predeterminedly contacted with the belt wheel of moving belt, and said traction layer is processed by polyester fiber (polyester fabric).

Preferably; Said with 30 having 10 to 30N/mm, preferably equaling the longitudinal modulus of elasticity of 20N/mm; That is to say the elastic modelling quantity on the direction of advance of band; And 2 to 10N/mm, preferably equal the transverse modulus of elasticity of 5N/mm, just at the elastic modelling quantity that is orthogonal on the direction of advance direction of band.

The elastic modelling quantity that point out the front normally is represented as K1% and has shown in order to realize that per unit width (1mm) goes up 1% the required tractive load of increase of length; Measure in hope on the direction of K1%, sample stretches on length.

In addition, preferably, band according to the present invention has 270 to 310 millimeters width, common 285 or 299 millimeters, and has ± 0.5 millimeter tolerance.
