Round seam smoothing machine

The basic configuration offers a highly robust machine focused on its essential core functions.

Round cylinders can be rotated and welded on the turntable or roller table; however, this version is not designed for tanks with feet. In such cases, the cylinder is moved via individual floor rollers. The machine is driven by three motors, with the spinning machine's drive designed as a frictional lock.

Alle Vorteile auf einen Blick

A sturdy, low-torsion steel base, CNC machined to accommodate bearings.
Rotation speed (standard equipment): 0.05-1.2 rpm
Container diameter (standard equipment): min. 1,100 mm, max. 2,100 mm
Shot height: max. 2,000 mm, min. 800 mm.
Max. container height to the center of the rolls: 2,000 mm

Two machined cantilever arms, equipped with two special smoothing tubes (one 250 mm, one 350 mm), double-row precision ball bearings, hardened and ground.
Working height (lower edge of spinning machine): 750 mm. The system is not embedded in the ground.
Special mounting for roller pressure cylinders, including hydraulic pump (0-200 bar, 1-12 tons).
Driven axles, left/right movement, and rapid traverse.
Control panel without touch display (designed for use with gloves), digital potentiometer for speed, remote maintenance.
2/4-stroke control, one foot switch each for program selection (back/forward), emergency stop.

Robust round seam smoothing machine for increased load capacity

The robust version of the machine is designed for press thicknesses of 2 to 10 mm. For this purpose, the welded construction is reinforced with additional steel and ribs, and the bearing and contact pressure of the cylinder is increased to 12 to 25 tons. This version cannot be combined with a taller configuration.

Circular seam smoothing machine at higher height for extended pressing range

The height of the tower is increased to 2,600 mm. This area contains the center of the rollers, which take over the subsequent pressing or pressing of the workpiece.

Round seam smoothing machine with grinding device in the middle

For sanding the inner seam, we offer a belt sander attachment with a pneumatic pressure unit. The unit is flexibly mounted via a proportional valve and is equipped with a suction device which can be connected directly to suitable filter technology. The filter technology itself is not included in the offer, but can be added later.

Both the belt speed and the contact pressure of 0.5 to 6 bar can be adjusted via the PLC. The grinding device is mounted on the same telescopic arm as the gas shower, but on the opposite side. If the gas shower is not configured, an additional charge applies for the telescopic arm.

Longitudinal seam smoothing machine

In the basic configuration, we provide a significantly robust machine that is concentrated on its essential core functions.

Round cylinders can be rotated and welded on the turntable or roller table; tanks with feet are not intended for this version. In this case, the cylinder is moved via individual floor rollers. The drive is carried out by three motors, with the drive in the spinning machine designed as a frictional lock.

Longitudinal seam welding machine with larger length for extended pressing range

In this version, the length of the tower is increased to 2,000 mm. This allows workpieces up to 2,000 mm in length to be pressed.

Longitudinal seam welding machine in larger length for extended pressing range – closed design variant

The length of the tower is increased by 1,000 mm per position. One side is equipped with a hydraulic lock to secure the unit against bending open. In this way, workpieces with a length of up to 10,000 mm can be pressed.

Longitudinal seam welding machine with grinding device

For sanding the outer seam, we offer a belt sander attachment with a pneumatic pressure unit. The unit is float-mounted via a proportional valve and is equipped with a suction device that can be connected directly to suitable filter technology. The filter technology itself is not included in the offer, but can be added later.

Both the belt speed and the contact pressure, ranging from 0.5 to 6 bar, can be adjusted via the PLC. The grinding device is mounted on the same telescopic arm as the gas shower, but on the opposite side. If the gas shower is not configured, there will be a corresponding additional charge for the telescopic arm.
