SPOOL CARRIAGE UNIT
2
GENERAL UNIT DESCRIPTION
4
–
The "PGS" type spool carriage unit was designed and constructed to unwind and
pre-stretch polythene stretch film
(A)
.
–
The carriage is reversible and allows wrapping according to the type of product to
wrap and of the type of spool available (adhesive externally or internally). The low
film consumption and homogeneous weight on each pallet allow a consistent reduc-
tion on operating costs.
–
The carriage is equipped with driven pre-stretch rolIers
(B)
, that rotate with different
peripheral speed.
–
The variation of the pre-stretch value, at preset values, is obtained by simply replac-
ing ratios, according to film’s characteristics and packaging requirements.
–
The stretch effect on the film between the rollers before load wrapping, in addition to
reducing the section, provides physical characteristics that make it more resistant to
keep the load intact during subsequent handling.
–
Further, an automatic roller device, with loading cell
(C)
, controls outfeed film tension
next to the pallet corners.
