Continuous feeding equipment consisting of:
 Decoiler Decoiler with expandable mandrel mm. 430 to mm. 520. Maximum capacity kg. 5000,
 Hydraulic controls.
 Tape launcher group
Welded steel base that in a single base collects:
 "Head" locking vices coming from the reel.
 Cutting and welding equipment of the above head with the tail of the belt already thrown into the collection pit.
 Locking vise of the aforementioned tail.
 Belt launching unit in accumulation pit with Hp 20 cc engine
TUBE LINE “YODER” Ø from 21,3 mm up to 102 mm.
 All hydraulic controls with Hp 7.5 engine
 Belt collection pit
- The belt collection pit is adjustable as needed with a spare capacity of approximately 400 linear meters.
 Machine base forming area
- The base supports all the part of the Forming Pipe, it is made up of very thick separable sides, built in mechanical cast iron, and equipped with internal ribs.
- The carefully planed sides are fixed to each other by means of steel tie rods and bolts.
- The base of the base is of planed sheet metal, AG62, with a thickness of 35 mm; it is fixed to the sides by means of 16 mm Allen bolts.
 Unnerving calender
- It consists of a 5-roller steel apparatus, which has the function of flattening the belt.
 Ribbon Guide
- It consists of two independent cages, approximately 400mm apart, with two adjustable guide rollers rotating on ball bearings
 Tube forming group
It’s composed by;
- 4 vertical passages with motorized cages only for lower rollers, while the idle upper rollers are pulled by the belt in contact with the lower rollers,
- Three vertical "Fin Pass" cages with both motorized roller holder shafts.
TUBE LINE “YODER” Ø from 21,3 mm up to 102 mm.
- The cage is a cast iron carcass, which houses a
system of transmission both for dragging on the belt and for moving the joint to the next one.
- Seven movable shoulders in special cast iron, which are coupled to the drive cage
supports the roller holder shafts, it is fixed to the base by means of special quick-locking brackets.
- Six cages with horizontal axes, consisting of a double control base side for height adjustment and self-centering.
- One head carries vertical rollers, uniform and guide the edge of the belt first
of the entry of the tape itself into the sealing unit.
 Soldering group.
- The welding unit consisting of a steel bench with 2 rollers on the axis self-centering horizontal.
- Two horizontally and vertically adjustable blocks complete the welding area tool holder for removing the excessive weld bead.
 Cooling unit
- An electric pump ensures the forced circulation of lubricated cooled water, which is distributed by means of a complex system of pipes and fittings, in all the points where lubrication and cooling are necessary.
- More specifically, the newly welded tube passes into a bathroom and simultaneously under a series of showers, therefore its temperature is reduced so as to allow perfect calibration.
 Machine base calibration zone
The base is completely similar to the base described in the "Forming Zone"
 Tube calibration group.
- It consists of 4 vertical cages and n. 4 horizontal calibration cages also in this case completely similar to those described for forming.
 Straightening group
- It consists of no. 3 double shoulder TT support base units, made of special mechanical cast iron,
- Each support can support 2 roller holder brackets adjustable in all directions by means of a lateral control and handwheel.
- Appropriate rollers mounted on the brackets above provide for the roundness of the tube, or for the possible transformation of the round tube with a square or rectangular section.
TUBE LINE “YODER” Ø from 21,3 mm up to 102 mm.
 Miter saw
• Flying saw with cold saw Type MTM A100.
• Base made of electro-welded and mechanically worked sheet metal.
• Guides in hardened and ground steel.
• Group-cutting trolley sliding on idle wheels.
• Cutting unit with AC gear motor complete with electronic speed variator to optimize the speed of the blade in relation to the diameter, the number of teeth, the thickness of the tube and the material to be cut. The cutting speed of the blade can be adjusted from 15 to 180 m / min.
• Hydraulic clamps group that ensures the locking of the tube during cutting, without causing deformations; a linear transducer adjusts the blade stroke in relation to the diameter in order to best contain the cutting time; a proportional hydraulic valve regulates the penetration speed of the blade and its return speed when empty.
- Vices prepared for tube cutting max. Ø 89
- Shock absorber assemblies for the carriage limit switch, emergency stop
- DC motor unit with pinion and rack for the transmission of motion to the saw carriage.
- Chip collection tank and blade lubrication emulsion.
- Centralized automatic lubrication unit,
- Cable chain
- Hydraulic unit
- Electrical and electronic cabinet
- Control pulpit with display to view the functions of the system.
- Electrical system for manual and automatic operation for the line
- A special electronic unit adjusts the speed of the flying saw to the speed of the profiling line in the shortest possible time, even during acceleration and deceleration, counting the length to be cut with absolute precision and controlling the entire cutting operation.
- In addition, data can be set from the control console to be able to cut and count the desired number of bars of the desired length for about 50 different types of work orders.
