stenter frame with fabric feed and delivery on opposite sides S-M
is a new model of stenter frame joining the advantages of the multipass
machine (improved fabric quality and reduced overall dimensions)
to the easy operation of the single-pass one (all feed, selvedge
gluing and cutting devices are readily accessible and easily kept
is manufactured in several models according to number of passes
and hence fabric content inside the chamber (up to 120 m maximum).
Fabrics are consequently processed at lower temperatures than in
single-pass stenter frames with definitely better results as far
as enhanced appearance, final "handle" and dimensional
stability are concerned.
S-M stenter frame is produced with different useful widths starting
from 180 cm up to 320 cm maximum.
fine and independent control of the overfeed drum speed ensures
a steady fabric overfeed on the nail chain (up to +60% maximum)
according to the different selvedge tension. Inlet double-hinge
swivel arms prevent any weft distortion.
S-M stenter frame can comprise 2 chambers, each equipped with its
own temperature control: the lower chamber for drying and the upper
one for heatsetting.
outlet cooling system via air blown onto both fabric sides while
it is still pinned ensures the best conditions for fabric dimensional
(optional) automatic filter cleaning ensures a steady performance
of the plant. The filters run before a rotating brush inside a vacuum
pipe connected with a sucking device and a bag filter outside the
machine. The brush rotates in the opposite direction of the filters,
thus crumbling the layer of lint which is sucked into the duct and
conveyed to the outer filter. Dust and lint cannot therefore fall
into the stenter frame. During cleaning, air filtering is carried
out by additional filters in a fixed position.
have pins and counter-pins and are equpped with (automatically lubricated)
ball bearings to reduce friction against the sliding guides. The
pictures show how compact and manifold the plant is.
the machine stops, an automatic flap stops ventilation onto the
processed fabric. However, air goes on circulating through a part
og the circuit (fans - gas burners or batteries - filters) thus
preventing any marking of the fabric inside the chamber and ensuring
minimal re-setting up times.
