The side roller is idle and it moves up and
down. Adjustment of the lower roller for pinching the plate
is by means of a handle at the front of the machine. This
movement can be motorized on request. Rotations is by means
of a self-braking motor, a reduction-gear and a pinion-crown
system with chain. The self-braking motor allows the plate
to be moved very slightly, which is useful during initial
forming. Traversing is controlled by an electric motor,
chain transmission and reduction unit. The machine complies
with the applicable safety prevention standards (CE-Machine
Directive).
Standard equipment:
- Motorized top and lower rollers rotation
- Side roll idle with movement of translation (up/down)
- Adjustment of the lower pinching roll manual by means
of an handle
- Pedal-foot operated rotation and translation
- Section bending rolls device (only for mod. Export)
- User’s manual
- CE mark
Optionals:
- Longitudinal groove
- Cone rolling device
- Section bending rolls device (only for mod. Export 170/220)
- Pneumatic drop-end opening (only for mod. Export 170/220)
- Universal set of section bending rolls
- Induction hardening of the rolls
- Third drive roll
- Lower roll motorization (pinching)
- Led readout for side roll
System:
- Lower roller C to the limit switch
- Insert the plate, making sure it does not project past
the axis of the roller B (Fig. 1)
- Lock the plate between roller A and roller B and raise
roller C for initial pre-bending (Fig. 2)
- Remove the plate from the machine, rotate it 180°
and re-insert it between the rollers
- Pre-bending the other side of the plate (Fig. 3)
- Activated roller rotation to start tube formation (Fig.
4)
