procedures and with regards to the control system, making it possible to
adjust this machine to the customers requirements.
- A complete press street consists of lifting table complete
with loading unit, brushing and glue spreading machine, disc rollerway, the
press itself and the discharge unit for the staking of the finished
workpieces.

Short phase pressing plant HKP

Sturdy, strong and durable - a press concept for a multitude of coating tasks.
Our know-how with respect to press construction, guarantees easy operation and
good-quality results. The HKP is manufactured according to the customer's
requirements and can therefore be constructed to fit into existing work
procedures. |

ORMA
PFH COLD presses
- Our PFH presses are the result of a long experience in
the field of cold gluing.
The frame of the press is obtained by welding together steel beams.
Both the top and the bottom platens are planed in order to have a better
flatness of the pressing surfaces.
- The top platen can be splitted in two or four (upon
request) independently and work at different pressures. Feeding and
outfeeding made easy by series of rollers mounted on
springs that permit them to be lowered when pressing.

Cold press - PFL SERIES
- Upper movable platen (end loading)
- Our PFL presses are the result of a long experience in
the field of cold gluing. The frame of the press is obtained by welding
together steel beams. Both the top and the bottom platens are planed in
order to have a better flatness of the pressing surfaces. The top platen
can be split in two or four (upon request) independently and work at
different pressures.
- Feeding and out feeding made easy by series of rollers
mounted on springs that permit them to be lowered when pressing.

Cold press - HL SERIES
- Bottom movable platen (side loading)
- Our HL presses are the result of a long experience in the
field of cold gluing. The frame of the press is obtained by welding together
steel beams. Both the top and the bottom platens are planed in order to have
a better flatness of the pressing surfaces. The top platen can be split in
two or four (upon request) independently and work at different pressures.

Hydraulic system
- The rams are thickness chromed to grant a perfect flowing
and a higher working life either of the seal gaskets or the piston itself.
Even in this case quality has been our main concern, and we've chosen the
thickest chromed system instead of the one by chrome bath which has lower
costs but absolutely no lasting guarantee.
- All the pistons are bolted to the structure, so to be
easily removed in case of servicing. Another possibility is to weld
pistons to the structure but in so doing all the functions of the press
would be of a much lower quality.
- High reliability hydraulic power unit with a double pump
system; one with low pressure for the platen quick closure and automatic
plugging of the other one, at high pressure, to reach the pressure set to
the pressure gauge by the operator.
- Hydraulic Power unit motor plunged in oil bath to obtain
a better cooling and to reduce noise, further on to avoid any possible
damages caused by accidental shocks.
Mechanical elements
- All the NPC Presses are fitted with a crossed racks
system so composed: 2 racks group for the platen depth and 2 groups for
the length all connected between them by torsion shafts so to grant a
perfect platen movement.
- Nr. 4 lateral guides, positioned on the 4 interior faces
of the press legs. This is a further guarantee of a perfect platen
movement during either their opening or closing.
- The press platens flatness is guaranteed by the precision
with which the beams are processed. In fact both the platens are made with
beams welded between them and after mechanically milled.
|
 |
|
MAIN CHARACTERISTICS:
-
Upstroke movement of the pressing
platen.
-
N. 4/6 pistons granting a uniform
pressure.
-
Hydraulic unit complete with double
stage pump for a faster platen closing, pressure regulation hand wheel
and safety switch.

ORMA ECONOMICAL PCL - C - PRESSES
Our hydraulic presses are very easy to be operated. The "PCL"
and "C" cold hydraulic presses are the results of ten
years experience in this field.
- The "PCL" presses have top
movable platen while the "C" have bottom movable
platen.
- The bearing structures are obtained by together assembling
beams, tubules and casings granting special strength and resistance to the
presses; the platens are covered with aluminum. Upon request, the "PCL"
and "C" presses can be supplied with automatic
pressure recovery.
- The hydraulic presses Ormamacchine series C4
- C6 are designed with the same criterion used for stronger
presses even if they are economic machines.

Handling properly panels on through feed presses has always been
a problem. To improve productivity and to facilitate these operations we
designed and now manufactured the device shown in the bottom picture.
(NPC/R) This device, or rather a double composite conveyor, allows the transfer
of boards from the glue spreading machine onto the press lay up table turning
them of 90°C the double conveyor, fixed to the press lay up table frame, is
composed by a powered system whose knives run orthogonally to the press and by a
free wheel conveyor, inserted in the same direction of the press infeed
conveyor.

|
ORMA ECONOMICAL PCL - C - PRESSES

Once boards are in loading position on the knife conveyor, acting on a lever, a
pneumatic circuit turns up the free wheel conveyor and let boards slide, for
gravity, onto the press lay up table. Through feed presses type NPC/R can be
chosen among our following standard sizes 2500 x1300, 3000 x 1300, 3500x1300;
working pressures range from 40 up to 200 ton. No standard sizes and working
pressures upon request. |
