This stenter is designed for tentering, drying, heatsetting and
curing of all woven textile fabrics used in the wool industry.
equipped with special pin plates, the stenter is suitable for carbonizing
processing of knit goods, the stenter frame will have to be equipped
with proper selvedge openers, gumming, cutting and suction devices:
this latter is our model M.
High evaporating capacity owing to large fabric content in a reduced
volume. The stenter can be supplied with 8, 10 or 12 runs: fabric
content varying between 38 metres and 78 metres.
accessibility through large doors which give immediate access
to the filters, heat exchangers, fans, chains, a.s.o.
maintenance requirements. Fans are directly coupled with threephase
electric motors. Each driven roll has its own driving inverter
motor. No belt driven transmission or mechanical speed variators
range from -10% to +40%, adjustable even at standstill via a rheostat.
Single selvedge tension adjustable by a rheostat, too.
edge sensor with dust and waterproof enclosed photocells with
mechanical feeler. Hence the combined advantages of positive edge
sensing with light barrier and electronic control.
speed arm displacements via hydraulic jacks controlled by solenoid
valves instead of pinion and rack system; hence higher displacement
speed due to lower inertia and fewer moving parts.
chain tensioning with constant tension.
equipped with ball-bearings which absorb the fabric tension forces
and allow to use the stenter even with heavy felts. Power consumption
and the need for lubrication are kept low due to rolling friction.
fabric holding elements are provided with pin plates and pinning
counter plates which prevent fabric deepening under all circumstances.
rails are formed by a drawn steel section and almost totally enclose
chain lubrication with adjustable electric programmer: lubricating
oil is directly fed to the chain guides and bearings.
blowing nozzles are fitted close to the chain guides to allow
periodical cleaning of both elements and bearings. The nozzles
are designed with quick release couplings for connection to the
compressed air network of the plant.
number of air blowing nozzles on both sides of the fabric. These
are of the circular jet type, with side plates, which produce
an air cushion above and under the fabric.
tunnel divided into 2 heating zones: the first one for drying
the fabric, the second one for heat setting or drying in case
of pure woollen fabrics. The air temperature in each zone can
be automatically and independently regulated via electronic temperature
stenter can be supplied for any of the following heating media:
- thermal fluid
- fuel oil (indirect heating)
all cases the heaters are largely dimensioned and allow a quick
rise to working temperature as well as a precise temperature regulation.
external panels are double walled and lagged with rock wool. They
are designed for a maximum working temperature of 250° C.
stenter can be fitted with a large number of accessories as per
frame designed to receive fabric in folds, the inlet frame is
provided with braking rods, automatic centering by means of pneumatically
operated roller frame with electronic photo-cell control.
weftstraightener built in the inlet frame, that is manually controlled
and consists also of a roller frame which is pneumatically operated.
exit end of the stenter is supplied with a plaiter. The pull roll
speed can be adjusted by means of a pneumatic compensator thus
allowing bow weft correction.
suction drum cooler can be installed before the plaiter. This
device is particularly recommended when blankets have to be cooled
down for downstream operations such as raising a.s.o.
